自私挖矿攻击：解释

<span data-sheets-root="1" data-sheets-value="{"1":2,"2":"Quick Summary\n\nWithin the cryptocurrency community, there has been much discussion on the heated topic of selfish mining. Basically, selfish mining is a tactic used by a miner or group of miners to boost earnings by taking advantage of flaws in the mining procedure. Some believe it is used for the best interests of the miners; however, some claim that it is a destructive force that negatively affects the crypto-mining industry.\n\nThis blog aims to provide you with a detailed view of selfish mining, its working, potential threats against the blockchain and effects on the mining ecosystem.\n\nWhat is Selfish Mining?\n----image1---\nWithholding or postponing the release of new blocks on purpose in order to obtain a competitive edge over other miners is known as selfish mining. The usual procedure for a miner to add a new block to their copy of the blockchain is to broadcast it to the network.\n\nIt can be defined simply as the state in which a single miner or group of miners controls more than half of the overall hash rate, enabling them to influence the blockchain to their benefit. With selfish mining, the miner can decide to keep the block a secret and carry on mining on top of it to extend the chain. As a result, other miners’ work on shorter chains can be declared invalid, and this longer chain can be broadcast to the network.\n\nMiners execute selfish mining to maximize their income, which involves keeping newly found blocks hidden from the rest of the network and only revealing them once another miner has figured out the puzzle for the next block. It increases the selfish miners’ likelihood of mining the next block by giving them a head start on solving the next block.\n\nHow does Selfish Mining work?\n---image2----\nThe freshly generated blocks are hidden by miners and made accessible on private chains or secret networks. This procedure reduces network latency problems, speeds up the process of finding a new block, and lowers overall operation costs. In the beginning, a branched blockchain is shorter than a public blockchain. The network’s nodes are organized into various blocks. As much as possible, two can be created simultaneously. The blockchain gets forked when two chains are published concurrently and linked by the final block.\n\nIn this method, a private chain is formed that both creates and hides new blocks. Until the private blockchain’s block height crosses that of the public blockchain, the entire procedure is repeated. The freshly formed blocks are subsequently added to the public blockchain by the selfish miners. The “honest” public blockchain effectively merges with the forked chain. The newly adopted blocks and cryptocurrency are awarded to the miners who successfully mine the new blockchain on the public chain.\n\nEach miner begins in State 0, which is the initial state. In state 1, a selfish miner extracts one fresh block and conceals it. State 2 shows that while the selfish miner hides one block, the honest miner declares that it has mined one new block. The selfish miner then displays its concealed block right away. The state would merge into State 3 in the meantime. In this scenario, some miners would obtain blocks from selfish miners and use those blocks as the foundation for mining the subsequent block. As long as it mines successfully on the blocks found by selfish miners, it may ensure a profit regardless of whether it is an honest or selfish mining block.\n\nHow is Selfish Mining a threat to crypto miners?\n\nThe security, dependability, and integrity of the blockchain networks are all impacted by the large and severe impacts of selfish mining on cryptocurrency miners and the mining sector.\n\n A few dangers to the industry are listed below:\n\n*Security Risk\nThe network’s security is the main thing that selfish mining affects. The blockchain’s consensus mechanism can be manipulated by a miner or group of miners that possess more than 50% of the network’s processing power. It can result in the issuance of erroneous blocks that impair the network’s operation. Double-spending attacks, in which a user spends the same bitcoin twice, may result from this manipulation. Users may suffer large financial losses as a result, and the blockchain’s reputation may be destroyed. In addition, the network’s security has been weakened, leaving it open to malicious activity and hacker assaults.\n\n*Decentralization\nThe blockchain network’s decentralization is impacted by selfish mining as well. A single entity can influence a network’s decision-making process if it possesses more than 50% of its processing power. The philosophy of blockchain technology, which is predicated on decentralization and transparency, stands in opposition to this concentration of power. Furthermore, selfish mining hinders small miners’ ability to engage with the network, which increases power centralization.\n\n*Network Congestion\nAn excessive number of transactions on the network might cause congestion, which is another issue that selfish mining can cause. A poor user experience may result from this congestion, which can cause delays in transaction processing and higher transaction fees.\n\n*Reputational Damage\nThe blockchain’s reputation may be harmed as a result of the selfish mining industry’s effects. Users may decide to move to other options if they lose faith in the security and dependability of the network, which could result in a loss of market share and a drop in the network’s value.\n\n*Loss of Transaction Fees\nIn the blockchain network, selfish mining may result in a loss of transaction fees. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. It can result in a backlog of pending transactions, which would lower the transaction fees that miners get paid.\n\n*Extended Confirmation Times\nTransactions in the blockchain network may take longer to confirm as a result of selfish mining. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. Users of the network may become irritated if this causes a delay in transaction confirmation\n\nHow does the Selfish Mining attack affect Bitcoin’s security?\n\n*The network’s overall hash power will become increasingly concentrated in the hands of a small number of dominant individuals as avaricious miners hoard freshly produced blocks. The Bitcoin network may become more centralized as a result of this hash power concentration, weakening its decentralization and freedom from controlling authorities.\n*A 51% attack might be launched by a single miner or group of miners who own more than 50% of the network’s hash power. It would enable them to double-spend bitcoins and risk the security of the entire network. Selfish miners can potentially obtain control over the network and raise their relative hash power by withholding newly generated blocks, threatening the security of the whole network.\n*Selfish miners may raise transaction costs for the rest of the network by withholding freshly mined blocks, which could result in a drop in the uptake and use of Bitcoin. The network’s worth and finances may be impacted as a result of this drop in adoption.\n*When a miner engages in selfish mining, they fail to notify the network of the blocks they have already mined, causing other miners to use computational resources trying to mine already-mined blocks. As a result, the selfish miner has an edge over other miners and may eventually collect a major portion of the mining rewards and, as a result, more control over the network.\n\nHow do we prevent Selfish Mining attacks?\n\nSelfish mining withholds blocks from the blockchain, putting its integrity at risk and perhaps causing centralization. Several actions may be taken, and some of them have been taken to lessen the negative effects of selfish mining on the network. Let’s examine the improvements and cures that have been suggested to combat selfish mining.\n\n1. Network Upgrades\nIncreasing the network’s resistance to selfish mining is one of the best strategies to combat it. It is best to change the blockchain protocol to combat selfish mining. For example, miners more commonly use the Ghost protocol for the Ethereum token. Selfish mining is strictly prohibited by the protocol, which pays miners who validate their blocks earlier with larger rewards.\n\n2. Restricting Selfish Miners\nRestricting selfish miners is an additional measure to combat the issue. Finding the selfish miners and adding them to a blocklist will help achieve this. Although this strategy has its uses, it is not infallible. To avoid being discovered, miners can switch up their identities or relocate to various pools.\n\n3. Encouraging Honest Mining\nSome suggestions advocate for rewarding honest mining as a means of combating selfish mining. One way to prevent selfish mining is to impose penalties on miners who engage in such behaviour.\n\n4. Cooperation among Miners\nPromoting collaboration among miners can help combat selfish mining. Before releasing their blocks to the network, miners can, for instance, decide to share them. It aids in guaranteeing that the longest chain is consistently selected.\n\n5. Reducing the Mining Reward\nAnother useful strategy for combating selfish mining is to alter the mining reward. For instance, miners might be less inclined to participate in selfish mining if the reward for discovering a block is decreased. In the same way, increasing the reward for publishing a block first might discourage mining that is motivated by greed.\n\n6. Using a different consensus algorithm\nAs an alternative consensus process, proof-of-stake (PoS) depends on validators rather than miners to produce new blocks. Validators have a lower incentive to participate in selfish mining since they are at risk of losing more because their decision is based on their stake in the network. PoS does, however, come with a unique set of difficulties, including the possibility of centralization and the initial token distribution.\n\nRead this blog: Cryptocurrency Mining Scams Explained(add Link)\n\n"}" data-sheets-userformat="{"2":641,"3":{"1":0},"10":0,"12":0}" data-sheets-textstyleruns="{"1":0,"2":{"5":1}} {"1":14}{"1":595,"2":{"5":1}} {"1":619}{"1":1693,"2":{"5":1}} {"1":1723}{"1":3432,"2":{"5":1}} {"1":3482}{"1":3668,"2":{"5":1}} {"1":3726}{"1":6203,"2":{"5":1}} {"1":6265}{"1":7644,"2":{"5":1}} {"1":7686}{"1":8027,"2":{"5":1}} {"1":8046}{"1":8426,"2":{"5":1}} {"1":8455}{"1":8766,"2":{"5":1}} {"1":8794}{"1":8987,"2":{"5":1}} {"1":9014}{"1":9252,"2":{"5":1}} {"1":9281}{"1":9616,"2":{"5":1}} {"1":9656}" data-mce-fragment="1">快速摘要 <span data-sheets-root="1" data-sheets-value="{"1":2,"2":"Quick Summary\n\nWithin the cryptocurrency community, there has been much discussion on the heated topic of selfish mining.

As a result, other miners’ work on shorter chains can be declared invalid, and this longer chain can be broadcast to the network.\n\nMiners execute selfish mining to maximize their income, which involves keeping newly found blocks hidden from the rest of the network and only revealing them once another miner has figured out the puzzle for the next block. It increases the selfish miners’ likelihood of mining the next block by giving them a head start on solving the next block.\n\nHow does Selfish Mining work?\n---image2----\nThe freshly generated blocks are hidden by miners and made accessible on private chains or secret networks. This procedure reduces network latency problems, speeds up the process of finding a new block, and lowers overall operation costs. In the beginning, a branched blockchain is shorter than a public blockchain. The network’s nodes are organized into various blocks. As much as possible, two can be created simultaneously. The blockchain gets forked when two chains are published concurrently and linked by the final block.\n\nIn this method, a private chain is formed that both creates and hides new blocks. Until the private blockchain’s block height crosses that of the public blockchain, the entire procedure is repeated. The freshly formed blocks are subsequently added to the public blockchain by the selfish miners. The “honest” public blockchain effectively merges with the forked chain. The newly adopted blocks and cryptocurrency are awarded to the miners who successfully mine the new blockchain on the public chain.\n\nEach miner begins in State 0, which is the initial state. In state 1, a selfish miner extracts one fresh block and conceals it. State 2 shows that while the selfish miner hides one block, the honest miner declares that it has mined one new block. The selfish miner then displays its concealed block right away. The state would merge into State 3 in the meantime. In this scenario, some miners would obtain blocks from selfish miners and use those blocks as the foundation for mining the subsequent block. As long as it mines successfully on the blocks found by selfish miners, it may ensure a profit regardless of whether it is an honest or selfish mining block.\n\nHow is Selfish Mining a threat to crypto miners?\n\nThe security, dependability, and integrity of the blockchain networks are all impacted by the large and severe impacts of selfish mining on cryptocurrency miners and the mining sector.\n\n A few dangers to the industry are listed below:\n\n*Security Risk\nThe network’s security is the main thing that selfish mining affects. The blockchain’s consensus mechanism can be manipulated by a miner or group of miners that possess more than 50% of the network’s processing power. It can result in the issuance of erroneous blocks that impair the network’s operation. Double-spending attacks, in which a user spends the same bitcoin twice, may result from this manipulation. Users may suffer large financial losses as a result, and the blockchain’s reputation may be destroyed. In addition, the network’s security has been weakened, leaving it open to malicious activity and hacker assaults.\n\n*Decentralization\nThe blockchain network’s decentralization is impacted by selfish mining as well. A single entity can influence a network’s decision-making process if it possesses more than 50% of its processing power. The philosophy of blockchain technology, which is predicated on decentralization and transparency, stands in opposition to this concentration of power. Furthermore, selfish mining hinders small miners’ ability to engage with the network, which increases power centralization.\n\n*Network Congestion\nAn excessive number of transactions on the network might cause congestion, which is another issue that selfish mining can cause. A poor user experience may result from this congestion, which can cause delays in transaction processing and higher transaction fees.\n\n*Reputational Damage\nThe blockchain’s reputation may be harmed as a result of the selfish mining industry’s effects. Users may decide to move to other options if they lose faith in the security and dependability of the network, which could result in a loss of market share and a drop in the network’s value.\n\n*Loss of Transaction Fees\nIn the blockchain network, selfish mining may result in a loss of transaction fees. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. It can result in a backlog of pending transactions, which would lower the transaction fees that miners get paid.\n\n*Extended Confirmation Times\nTransactions in the blockchain network may take longer to confirm as a result of selfish mining. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. Users of the network may become irritated if this causes a delay in transaction confirmation\n\nHow does the Selfish Mining attack affect Bitcoin’s security?\n\n*The network’s overall hash power will become increasingly concentrated in the hands of a small number of dominant individuals as avaricious miners hoard freshly produced blocks. The Bitcoin network may become more centralized as a result of this hash power concentration, weakening its decentralization and freedom from controlling authorities.\n*A 51% attack might be launched by a single miner or group of miners who own more than 50% of the network’s hash power. It would enable them to double-spend bitcoins and risk the security of the entire network. Selfish miners can potentially obtain control over the network and raise their relative hash power by withholding newly generated blocks, threatening the security of the whole network.\n*Selfish miners may raise transaction costs for the rest of the network by withholding freshly mined blocks, which could result in a drop in the uptake and use of Bitcoin. The network’s worth and finances may be impacted as a result of this drop in adoption.\n*When a miner engages in selfish mining, they fail to notify the network of the blocks they have already mined, causing other miners to use computational resources trying to mine already-mined blocks. As a result, the selfish miner has an edge over other miners and may eventually collect a major portion of the mining rewards and, as a result, more control over the network.\n\nHow do we prevent Selfish Mining attacks?\n\nSelfish mining withholds blocks from the blockchain, putting its integrity at risk and perhaps causing centralization. Several actions may be taken, and some of them have been taken to lessen the negative effects of selfish mining on the network. Let’s examine the improvements and cures that have been suggested to combat selfish mining.\n\n1. Network Upgrades\nIncreasing the network’s resistance to selfish mining is one of the best strategies to combat it. It is best to change the blockchain protocol to combat selfish mining. For example, miners more commonly use the Ghost protocol for the Ethereum token. Selfish mining is strictly prohibited by the protocol, which pays miners who validate their blocks earlier with larger rewards.\n\n2. Restricting Selfish Miners\nRestricting selfish miners is an additional measure to combat the issue. Finding the selfish miners and adding them to a blocklist will help achieve this. Although this strategy has its uses, it is not infallible. To avoid being discovered, miners can switch up their identities or relocate to various pools.\n\n3. Encouraging Honest Mining\nSome suggestions advocate for rewarding honest mining as a means of combating selfish mining. One way to prevent selfish mining is to impose penalties on miners who engage in such behaviour.\n\n4. Cooperation among Miners\nPromoting collaboration among miners can help combat selfish mining. Before releasing their blocks to the network, miners can, for instance, decide to share them. It aids in guaranteeing that the longest chain is consistently selected.\n\n5. Reducing the Mining Reward\nAnother useful strategy for combating selfish mining is to alter the mining reward. For instance, miners might be less inclined to participate in selfish mining if the reward for discovering a block is decreased. In the same way, increasing the reward for publishing a block first might discourage mining that is motivated by greed.\n\n6. Using a different consensus algorithm\nAs an alternative consensus process, proof-of-stake (PoS) depends on validators rather than miners to produce new blocks. Validators have a lower incentive to participate in selfish mining since they are at risk of losing more because their decision is based on their stake in the network. PoS does, however, come with a unique set of difficulties, including the possibility of centralization and the initial token distribution.\n\nRead this blog: Cryptocurrency Mining Scams Explained(add Link)\n\n"}" data-sheets-userformat="{"2":641,"3":{"1":0},"10":0,"12":0}" data-sheets-textstyleruns="{"1":0,"2":{"5":1}} {"1":14}{"1":595,"2":{"5":1}} {"1":619}{"1":1693,"2":{"5":1}} {"1":1723}{"1":3432,"2":{"5":1}} {"1":3482}{"1":3668,"2":{"5":1}} {"1":3726}{"1":6203,"2":{"5":1}} {"1":6265}{"1":7644,"2":{"5":1}} {"1":7686}{"1":8027,"2":{"5":1}} {"1":8046}{"1":8426,"2":{"5":1}} {"1":8455}{"1":8766,"2":{"5":1}} {"1":8794}{"1":8987,"2":{"5":1}} {"1":9014}{"1":9252,"2":{"5":1}} {"1":9281}{"1":9616,"2":{"5":1}} {"1":9656}" data-mce-fragment="1">什么是自私挖矿？ <span data-sheets-root="1" data-sheets-value="{"1":2,"2":"Quick Summary\n\nWithin the cryptocurrency community, there has been much discussion on the heated topic of selfish mining.

Until the private blockchain’s block height crosses that of the public blockchain, the entire procedure is repeated. The freshly formed blocks are subsequently added to the public blockchain by the selfish miners. The “honest” public blockchain effectively merges with the forked chain. The newly adopted blocks and cryptocurrency are awarded to the miners who successfully mine the new blockchain on the public chain.\n\nEach miner begins in State 0, which is the initial state. In state 1, a selfish miner extracts one fresh block and conceals it. State 2 shows that while the selfish miner hides one block, the honest miner declares that it has mined one new block. The selfish miner then displays its concealed block right away. The state would merge into State 3 in the meantime. In this scenario, some miners would obtain blocks from selfish miners and use those blocks as the foundation for mining the subsequent block. As long as it mines successfully on the blocks found by selfish miners, it may ensure a profit regardless of whether it is an honest or selfish mining block.\n\nHow is Selfish Mining a threat to crypto miners?\n\nThe security, dependability, and integrity of the blockchain networks are all impacted by the large and severe impacts of selfish mining on cryptocurrency miners and the mining sector.\n\n A few dangers to the industry are listed below:\n\n*Security Risk\nThe network’s security is the main thing that selfish mining affects. The blockchain’s consensus mechanism can be manipulated by a miner or group of miners that possess more than 50% of the network’s processing power. It can result in the issuance of erroneous blocks that impair the network’s operation. Double-spending attacks, in which a user spends the same bitcoin twice, may result from this manipulation. Users may suffer large financial losses as a result, and the blockchain’s reputation may be destroyed. In addition, the network’s security has been weakened, leaving it open to malicious activity and hacker assaults.\n\n*Decentralization\nThe blockchain network’s decentralization is impacted by selfish mining as well. A single entity can influence a network’s decision-making process if it possesses more than 50% of its processing power. The philosophy of blockchain technology, which is predicated on decentralization and transparency, stands in opposition to this concentration of power. Furthermore, selfish mining hinders small miners’ ability to engage with the network, which increases power centralization.\n\n*Network Congestion\nAn excessive number of transactions on the network might cause congestion, which is another issue that selfish mining can cause. A poor user experience may result from this congestion, which can cause delays in transaction processing and higher transaction fees.\n\n*Reputational Damage\nThe blockchain’s reputation may be harmed as a result of the selfish mining industry’s effects. Users may decide to move to other options if they lose faith in the security and dependability of the network, which could result in a loss of market share and a drop in the network’s value.\n\n*Loss of Transaction Fees\nIn the blockchain network, selfish mining may result in a loss of transaction fees. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. It can result in a backlog of pending transactions, which would lower the transaction fees that miners get paid.\n\n*Extended Confirmation Times\nTransactions in the blockchain network may take longer to confirm as a result of selfish mining. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. Users of the network may become irritated if this causes a delay in transaction confirmation\n\nHow does the Selfish Mining attack affect Bitcoin’s security?\n\n*The network’s overall hash power will become increasingly concentrated in the hands of a small number of dominant individuals as avaricious miners hoard freshly produced blocks. The Bitcoin network may become more centralized as a result of this hash power concentration, weakening its decentralization and freedom from controlling authorities.\n*A 51% attack might be launched by a single miner or group of miners who own more than 50% of the network’s hash power. It would enable them to double-spend bitcoins and risk the security of the entire network. Selfish miners can potentially obtain control over the network and raise their relative hash power by withholding newly generated blocks, threatening the security of the whole network.\n*Selfish miners may raise transaction costs for the rest of the network by withholding freshly mined blocks, which could result in a drop in the uptake and use of Bitcoin. The network’s worth and finances may be impacted as a result of this drop in adoption.\n*When a miner engages in selfish mining, they fail to notify the network of the blocks they have already mined, causing other miners to use computational resources trying to mine already-mined blocks. As a result, the selfish miner has an edge over other miners and may eventually collect a major portion of the mining rewards and, as a result, more control over the network.\n\nHow do we prevent Selfish Mining attacks?\n\nSelfish mining withholds blocks from the blockchain, putting its integrity at risk and perhaps causing centralization. Several actions may be taken, and some of them have been taken to lessen the negative effects of selfish mining on the network. Let’s examine the improvements and cures that have been suggested to combat selfish mining.\n\n1. Network Upgrades\nIncreasing the network’s resistance to selfish mining is one of the best strategies to combat it. It is best to change the blockchain protocol to combat selfish mining. For example, miners more commonly use the Ghost protocol for the Ethereum token. Selfish mining is strictly prohibited by the protocol, which pays miners who validate their blocks earlier with larger rewards.\n\n2. Restricting Selfish Miners\nRestricting selfish miners is an additional measure to combat the issue. Finding the selfish miners and adding them to a blocklist will help achieve this. Although this strategy has its uses, it is not infallible. To avoid being discovered, miners can switch up their identities or relocate to various pools.\n\n3. Encouraging Honest Mining\nSome suggestions advocate for rewarding honest mining as a means of combating selfish mining. One way to prevent selfish mining is to impose penalties on miners who engage in such behaviour.\n\n4. Cooperation among Miners\nPromoting collaboration among miners can help combat selfish mining. Before releasing their blocks to the network, miners can, for instance, decide to share them. It aids in guaranteeing that the longest chain is consistently selected.\n\n5. Reducing the Mining Reward\nAnother useful strategy for combating selfish mining is to alter the mining reward. For instance, miners might be less inclined to participate in selfish mining if the reward for discovering a block is decreased. In the same way, increasing the reward for publishing a block first might discourage mining that is motivated by greed.\n\n6. Using a different consensus algorithm\nAs an alternative consensus process, proof-of-stake (PoS) depends on validators rather than miners to produce new blocks. Validators have a lower incentive to participate in selfish mining since they are at risk of losing more because their decision is based on their stake in the network. PoS does, however, come with a unique set of difficulties, including the possibility of centralization and the initial token distribution.\n\nRead this blog: Cryptocurrency Mining Scams Explained(add Link)\n\n"}" data-sheets-userformat="{"2":641,"3":{"1":0},"10":0,"12":0}" data-sheets-textstyleruns="{"1":0,"2":{"5":1}} {"1":14}{"1":595,"2":{"5":1}} {"1":619}{"1":1693,"2":{"5":1}} {"1":1723}{"1":3432,"2":{"5":1}} {"1":3482}{"1":3668,"2":{"5":1}} {"1":3726}{"1":6203,"2":{"5":1}} {"1":6265}{"1":7644,"2":{"5":1}} {"1":7686}{"1":8027,"2":{"5":1}} {"1":8046}{"1":8426,"2":{"5":1}} {"1":8455}{"1":8766,"2":{"5":1}} {"1":8794}{"1":8987,"2":{"5":1}} {"1":9014}{"1":9252,"2":{"5":1}} {"1":9281}{"1":9616,"2":{"5":1}} {"1":9656}" data-mce-fragment="1">矿机执行自私挖矿以最大化他们的收入，这涉及将新发现的区块隐藏在网络的其余部分，并且只有当另一个矿机弄清楚下一个区块的谜题时才显示它们。它通过让自私矿机抢先解决下一个区块来增加他们挖矿下一个区块的可能性。

As long as it mines successfully on the blocks found by selfish miners, it may ensure a profit regardless of whether it is an honest or selfish mining block.\n\nHow is Selfish Mining a threat to crypto miners?\n\nThe security, dependability, and integrity of the blockchain networks are all impacted by the large and severe impacts of selfish mining on cryptocurrency miners and the mining sector.\n\n A few dangers to the industry are listed below:\n\n*Security Risk\nThe network’s security is the main thing that selfish mining affects. The blockchain’s consensus mechanism can be manipulated by a miner or group of miners that possess more than 50% of the network’s processing power. It can result in the issuance of erroneous blocks that impair the network’s operation. Double-spending attacks, in which a user spends the same bitcoin twice, may result from this manipulation. Users may suffer large financial losses as a result, and the blockchain’s reputation may be destroyed. In addition, the network’s security has been weakened, leaving it open to malicious activity and hacker assaults.\n\n*Decentralization\nThe blockchain network’s decentralization is impacted by selfish mining as well. A single entity can influence a network’s decision-making process if it possesses more than 50% of its processing power. The philosophy of blockchain technology, which is predicated on decentralization and transparency, stands in opposition to this concentration of power. Furthermore, selfish mining hinders small miners’ ability to engage with the network, which increases power centralization.\n\n*Network Congestion\nAn excessive number of transactions on the network might cause congestion, which is another issue that selfish mining can cause. A poor user experience may result from this congestion, which can cause delays in transaction processing and higher transaction fees.\n\n*Reputational Damage\nThe blockchain’s reputation may be harmed as a result of the selfish mining industry’s effects. Users may decide to move to other options if they lose faith in the security and dependability of the network, which could result in a loss of market share and a drop in the network’s value.\n\n*Loss of Transaction Fees\nIn the blockchain network, selfish mining may result in a loss of transaction fees. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. It can result in a backlog of pending transactions, which would lower the transaction fees that miners get paid.\n\n*Extended Confirmation Times\nTransactions in the blockchain network may take longer to confirm as a result of selfish mining. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. Users of the network may become irritated if this causes a delay in transaction confirmation\n\nHow does the Selfish Mining attack affect Bitcoin’s security?\n\n*The network’s overall hash power will become increasingly concentrated in the hands of a small number of dominant individuals as avaricious miners hoard freshly produced blocks. The Bitcoin network may become more centralized as a result of this hash power concentration, weakening its decentralization and freedom from controlling authorities.\n*A 51% attack might be launched by a single miner or group of miners who own more than 50% of the network’s hash power. It would enable them to double-spend bitcoins and risk the security of the entire network. Selfish miners can potentially obtain control over the network and raise their relative hash power by withholding newly generated blocks, threatening the security of the whole network.\n*Selfish miners may raise transaction costs for the rest of the network by withholding freshly mined blocks, which could result in a drop in the uptake and use of Bitcoin. The network’s worth and finances may be impacted as a result of this drop in adoption.\n*When a miner engages in selfish mining, they fail to notify the network of the blocks they have already mined, causing other miners to use computational resources trying to mine already-mined blocks. As a result, the selfish miner has an edge over other miners and may eventually collect a major portion of the mining rewards and, as a result, more control over the network.\n\nHow do we prevent Selfish Mining attacks?\n\nSelfish mining withholds blocks from the blockchain, putting its integrity at risk and perhaps causing centralization. Several actions may be taken, and some of them have been taken to lessen the negative effects of selfish mining on the network. Let’s examine the improvements and cures that have been suggested to combat selfish mining.\n\n1. Network Upgrades\nIncreasing the network’s resistance to selfish mining is one of the best strategies to combat it. It is best to change the blockchain protocol to combat selfish mining. For example, miners more commonly use the Ghost protocol for the Ethereum token. Selfish mining is strictly prohibited by the protocol, which pays miners who validate their blocks earlier with larger rewards.\n\n2. Restricting Selfish Miners\nRestricting selfish miners is an additional measure to combat the issue. Finding the selfish miners and adding them to a blocklist will help achieve this. Although this strategy has its uses, it is not infallible. To avoid being discovered, miners can switch up their identities or relocate to various pools.\n\n3. Encouraging Honest Mining\nSome suggestions advocate for rewarding honest mining as a means of combating selfish mining. One way to prevent selfish mining is to impose penalties on miners who engage in such behaviour.\n\n4. Cooperation among Miners\nPromoting collaboration among miners can help combat selfish mining. Before releasing their blocks to the network, miners can, for instance, decide to share them. It aids in guaranteeing that the longest chain is consistently selected.\n\n5. Reducing the Mining Reward\nAnother useful strategy for combating selfish mining is to alter the mining reward. For instance, miners might be less inclined to participate in selfish mining if the reward for discovering a block is decreased. In the same way, increasing the reward for publishing a block first might discourage mining that is motivated by greed.\n\n6. Using a different consensus algorithm\nAs an alternative consensus process, proof-of-stake (PoS) depends on validators rather than miners to produce new blocks. Validators have a lower incentive to participate in selfish mining since they are at risk of losing more because their decision is based on their stake in the network. PoS does, however, come with a unique set of difficulties, including the possibility of centralization and the initial token distribution.\n\nRead this blog: Cryptocurrency Mining Scams Explained(add Link)\n\n"}" data-sheets-userformat="{"2":641,"3":{"1":0},"10":0,"12":0}" data-sheets-textstyleruns="{"1":0,"2":{"5":1}} {"1":14}{"1":595,"2":{"5":1}} {"1":619}{"1":1693,"2":{"5":1}} {"1":1723}{"1":3432,"2":{"5":1}} {"1":3482}{"1":3668,"2":{"5":1}} {"1":3726}{"1":6203,"2":{"5":1}} {"1":6265}{"1":7644,"2":{"5":1}} {"1":7686}{"1":8027,"2":{"5":1}} {"1":8046}{"1":8426,"2":{"5":1}} {"1":8455}{"1":8766,"2":{"5":1}} {"1":8794}{"1":8987,"2":{"5":1}} {"1":9014}{"1":9252,"2":{"5":1}} {"1":9281}{"1":9616,"2":{"5":1}} {"1":9656}" data-mce-fragment="1">在这种方法中，会形成一条私链，它既会创建又会隐藏新区块。整个过程会重复进行，直到私链的区块高度超过公链的区块高度。随后，自私矿机会将新形成的区块添加到公链中。“诚实”的公链会有效地与分叉链合并。新采用的区块和加密货币将奖励给在公链上成功挖矿新区块链的矿机。

<span data-sheets-root="1" data-sheets-value="{"1":2,"2":"Quick Summary\n\nWithin the cryptocurrency community, there has been much discussion on the heated topic of selfish mining. Basically, selfish mining is a tactic used by a miner or group of miners to boost earnings by taking advantage of flaws in the mining procedure. Some believe it is used for the best interests of the miners; however, some claim that it is a destructive force that negatively affects the crypto-mining industry.\n\nThis blog aims to provide you with a detailed view of selfish mining, its working, potential threats against the blockchain and effects on the mining ecosystem.\n\nWhat is Selfish Mining?\n----image1---\nWithholding or postponing the release of new blocks on purpose in order to obtain a competitive edge over other miners is known as selfish mining. The usual procedure for a miner to add a new block to their copy of the blockchain is to broadcast it to the network.\n\nIt can be defined simply as the state in which a single miner or group of miners controls more than half of the overall hash rate, enabling them to influence the blockchain to their benefit. With selfish mining, the miner can decide to keep the block a secret and carry on mining on top of it to extend the chain. As a result, other miners’ work on shorter chains can be declared invalid, and this longer chain can be broadcast to the network.\n\nMiners execute selfish mining to maximize their income, which involves keeping newly found blocks hidden from the rest of the network and only revealing them once another miner has figured out the puzzle for the next block. It increases the selfish miners’ likelihood of mining the next block by giving them a head start on solving the next block.\n\nHow does Selfish Mining work?\n---image2----\nThe freshly generated blocks are hidden by miners and made accessible on private chains or secret networks. This procedure reduces network latency problems, speeds up the process of finding a new block, and lowers overall operation costs. In the beginning, a branched blockchain is shorter than a public blockchain. The network’s nodes are organized into various blocks. As much as possible, two can be created simultaneously. The blockchain gets forked when two chains are published concurrently and linked by the final block.\n\nIn this method, a private chain is formed that both creates and hides new blocks. Until the private blockchain’s block height crosses that of the public blockchain, the entire procedure is repeated. The freshly formed blocks are subsequently added to the public blockchain by the selfish miners. The “honest” public blockchain effectively merges with the forked chain. The newly adopted blocks and cryptocurrency are awarded to the miners who successfully mine the new blockchain on the public chain.\n\nEach miner begins in State 0, which is the initial state. In state 1, a selfish miner extracts one fresh block and conceals it. State 2 shows that while the selfish miner hides one block, the honest miner declares that it has mined one new block.

It can result in the issuance of erroneous blocks that impair the network’s operation. Double-spending attacks, in which a user spends the same bitcoin twice, may result from this manipulation. Users may suffer large financial losses as a result, and the blockchain’s reputation may be destroyed. In addition, the network’s security has been weakened, leaving it open to malicious activity and hacker assaults.\n\n*Decentralization\nThe blockchain network’s decentralization is impacted by selfish mining as well. A single entity can influence a network’s decision-making process if it possesses more than 50% of its processing power. The philosophy of blockchain technology, which is predicated on decentralization and transparency, stands in opposition to this concentration of power. Furthermore, selfish mining hinders small miners’ ability to engage with the network, which increases power centralization.\n\n*Network Congestion\nAn excessive number of transactions on the network might cause congestion, which is another issue that selfish mining can cause. A poor user experience may result from this congestion, which can cause delays in transaction processing and higher transaction fees.\n\n*Reputational Damage\nThe blockchain’s reputation may be harmed as a result of the selfish mining industry’s effects. Users may decide to move to other options if they lose faith in the security and dependability of the network, which could result in a loss of market share and a drop in the network’s value.\n\n*Loss of Transaction Fees\nIn the blockchain network, selfish mining may result in a loss of transaction fees. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. It can result in a backlog of pending transactions, which would lower the transaction fees that miners get paid.\n\n*Extended Confirmation Times\nTransactions in the blockchain network may take longer to confirm as a result of selfish mining. It is due to the possibility that selfish miners will obstruct the finding of fresh blocks, which could create a delay in transaction confirmation. Users of the network may become irritated if this causes a delay in transaction confirmation\n\nHow does the Selfish Mining attack affect Bitcoin’s security?\n\n*The network’s overall hash power will become increasingly concentrated in the hands of a small number of dominant individuals as avaricious miners hoard freshly produced blocks. The Bitcoin network may become more centralized as a result of this hash power concentration, weakening its decentralization and freedom from controlling authorities.\n*A 51% attack might be launched by a single miner or group of miners who own more than 50% of the network’s hash power. It would enable them to double-spend bitcoins and risk the security of the entire network. Selfish miners can potentially obtain control over the network and raise their relative hash power by withholding newly generated blocks, threatening the security of the whole network.\n*Selfish miners may raise transaction costs for the rest of the network by withholding freshly mined blocks, which could result in a drop in the uptake and use of Bitcoin. The network’s worth and finances may be impacted as a result of this drop in adoption.\n*When a miner engages in selfish mining, they fail to notify the network of the blocks they have already mined, causing other miners to use computational resources trying to mine already-mined blocks. As a result, the selfish miner has an edge over other miners and may eventually collect a major portion of the mining rewards and, as a result, more control over the network.\n\nHow do we prevent Selfish Mining attacks?\n\nSelfish mining withholds blocks from the blockchain, putting its integrity at risk and perhaps causing centralization. Several actions may be taken, and some of them have been taken to lessen the negative effects of selfish mining on the network. Let’s examine the improvements and cures that have been suggested to combat selfish mining.\n\n1. Network Upgrades\nIncreasing the network’s resistance to selfish mining is one of the best strategies to combat it. It is best to change the blockchain protocol to combat selfish mining. For example, miners more commonly use the Ghost protocol for the Ethereum token. Selfish mining is strictly prohibited by the protocol, which pays miners who validate their blocks earlier with larger rewards.\n\n2. Restricting Selfish Miners\nRestricting selfish miners is an additional measure to combat the issue. Finding the selfish miners and adding them to a blocklist will help achieve this. Although this strategy has its uses, it is not infallible. To avoid being discovered, miners can switch up their identities or relocate to various pools.\n\n3. Encouraging Honest Mining\nSome suggestions advocate for rewarding honest mining as a means of combating selfish mining. One way to prevent selfish mining is to impose penalties on miners who engage in such behaviour.\n\n4. Cooperation among Miners\nPromoting collaboration among miners can help combat selfish mining. Before releasing their blocks to the network, miners can, for instance, decide to share them. It aids in guaranteeing that the longest chain is consistently selected.\n\n5. Reducing the Mining Reward\nAnother useful strategy for combating selfish mining is to alter the mining reward. For instance, miners might be less inclined to participate in selfish mining if the reward for discovering a block is decreased. In the same way, increasing the reward for publishing a block first might discourage mining that is motivated by greed.\n\n6. Using a different consensus algorithm\nAs an alternative consensus process, proof-of-stake (PoS) depends on validators rather than miners to produce new blocks. Validators have a lower incentive to participate in selfish mining since they are at risk of losing more because their decision is based on their stake in the network. PoS does, however, come with a unique set of difficulties, including the possibility of centralization and the initial token distribution.\n\nRead this blog: Cryptocurrency Mining Scams Explained(add Link)\n\n"}" data-sheets-userformat="{"2":641,"3":{"1":0},"10":0,"12":0}" data-sheets-textstyleruns="{"1":0,"2":{"5":1}} {"1":14}{"1":595,"2":{"5":1}} {"1":619}{"1":1693,"2":{"5":1}} {"1":1723}{"1":3432,"2":{"5":1}} {"1":3482}{"1":3668,"2":{"5":1}} {"1":3726}{"1":6203,"2":{"5":1}} {"1":6265}{"1":7644,"2":{"5":1}} {"1":7686}{"1":8027,"2":{"5":1}} {"1":8046}{"1":8426,"2":{"5":1}} {"1":8455}{"1":8766,"2":{"5":1}} {"1":8794}{"1":8987,"2":{"5":1}} {"1":9014}{"1":9252,"2":{"5":1}} {"1":9281}{"1":9616,"2":{"5":1}} {"1":9656}" data-mce-fragment="1">自私挖矿对加密货币矿机和挖矿行业造成巨大而严重的影响，影响着区块链网络的安全性、可靠性和完整性。

<span data-sheets-root="1" data-sheets-value="{"1":2,"2":"Quick Summary\n\nWithin the cryptocurrency community, there has been much discussion on the heated topic of selfish mining. Basically, selfish mining is a tactic used by a miner or group of miners to boost earnings by taking advantage of flaws in the mining procedure. Some believe it is used for the best interests of the miners; however, some claim that it is a destructive force that negatively affects the crypto-mining industry.\n\nThis blog aims to provide you with a detailed view of selfish mining, its working, potential threats against the blockchain and effects on the mining ecosystem.\n\nWhat is Selfish Mining?\n----image1---\nWithholding or postponing the release of new blocks on purpose in order to obtain a competitive edge over other miners is known as selfish mining. The usual procedure for a miner to add a new block to their copy of the blockchain is to broadcast it to the network.\n\nIt can be defined simply as the state in which a single miner or group of miners controls more than half of the overall hash rate, enabling them to influence the blockchain to their benefit. With selfish mining, the miner can decide to keep the block a secret and carry on mining on top of it to extend the chain. As a result, other miners’ work on shorter chains can be declared invalid, and this longer chain can be broadcast to the network.\n\nMiners execute selfish mining to maximize their income, which involves keeping newly found blocks hidden from the rest of the network and only revealing them once another miner has figured out the puzzle for the next block. It increases the selfish miners’ likelihood of mining the next block by giving them a head start on solving the next block.\n\nHow does Selfish Mining work?\n---image2----\nThe freshly generated blocks are hidden by miners and made accessible on private chains or secret networks. This procedure reduces network latency problems, speeds up the process of finding a new block, and lowers overall operation costs. In the beginning, a branched blockchain is shorter than a public blockchain. The network’s nodes are organized into various blocks. As much as possible, two can be created simultaneously. The blockchain gets forked when two chains are published concurrently and linked by the final block.\n\nIn this method, a private chain is formed that both creates and hides new blocks. Until the private blockchain’s block height crosses that of the public blockchain, the entire procedure is repeated. The freshly formed blocks are subsequently added to the public blockchain by the selfish miners. The “honest” public blockchain effectively merges with the forked chain. The newly adopted blocks and cryptocurrency are awarded to the miners who successfully mine the new blockchain on the public chain.\n\nEach miner begins in State 0, which is the initial state. In state 1, a selfish miner extracts one fresh block and conceals it. State 2 shows that while the selfish miner hides one block, the honest miner declares that it has mined one new block. The selfish miner then displays its concealed block right away. The state would merge into State 3 in the meantime. In this scenario, some miners would obtain blocks from selfish miners and use those blocks as the foundation for mining the subsequent block. As long as it mines successfully on the blocks found by selfish miners, it may ensure a profit regardless of whether it is an honest or selfish mining block.\n\nHow is Selfish Mining a threat to crypto miners?\n\nThe security, dependability, and integrity of the blockchain networks are all impacted by the large and severe impacts of selfish mining on cryptocurrency miners and the mining sector.\n\n A few dangers to the industry are listed below:\n\n*Security Risk\nThe network’s security is the main thing that selfish mining affects.

安全风险 网络的安全性是自私挖矿影响的主要方面。区块链的共识机制可能被拥有超过 50% 网络处理能力的 矿机 或 矿机 群体操纵。这可能导致发布错误区块，从而损害网络的运行。这种操纵可能会导致双重支付攻击，即用户两次使用相同的比特币。用户可能会因此遭受巨额财务损失，区块链的声誉也可能遭到破坏。此外，网络的安全性已被削弱，使其容易受到恶意活动和黑客攻击。 去中心化 区块链网络的去中心化也受到自私挖矿的影响。如果单个实体拥有超过 50% 的处理能力，它就可以影响网络的决策过程。区块链技术的理念以去中心化和透明性为基础，与这种权力集中背道而驰。此外，自私挖矿会阻碍小 矿机 参与网络的能力，从而增加权力集中化。 网络拥塞 网络上的交易数量过多可能会导致拥堵，这是自私挖矿可能造成的另一个问题。这种拥堵可能会导致用户体验不佳，从而导致交易处理延迟和交易费用增加。 声誉损害 区块链的声誉可能会因自私挖矿行业的影响而受到损害。如果用户对网络的安全性和可靠性失去信心，他们可能会决定转向其他选择，这可能会导致市场份额的损失和网络价值的下降。 交易费损失 在区块链网络中，自私挖矿可能会导致交易费损失。这是因为自私 矿机 可能会阻碍新区块的发现，从而导致交易确认延迟。这可能会导致待处理交易积压，从而降低 矿机 获得的交易费。 延长确认时间 由于自私挖矿，区块链网络中的交易可能需要更长时间才能确认。这是因为自私的 矿机 可能会阻碍新区块的发现，从而导致交易确认延迟。如果这导致交易确认延迟，网络用户可能会感到恼火

自私挖矿攻击如何影响比特币的安全性？ 随着贪婪的 矿机 囤积新生成的区块，网络的整体哈希算力将越来越集中在少数占主导地位的个人手中。由于这种哈希算力集中，比特币网络可能会变得更加集中，从而削弱其去中心化程度和不受控制当局控制的自由度。 51% 攻击可能由拥有超过 50% 网络哈希算力的单个 矿机 或 矿机 组发起。这将使他们能够对比特币进行双重支付，并危及整个网络的安全。自私的 矿机 可能会通过扣留新生成的区块来获得对网络的控制权并提高其相对哈希算力，从而威胁整个网络的安全。 自私的 矿机 可能会通过扣留新开采的区块来提高网络其余部分的交易成本，这可能会导致比特币的采用和使用率下降。采用率下降可能会影响网络的价值和财务状况。 当 矿机 进行自私挖矿时，他们不会向网络通报他们已经挖出的区块，从而导致其他 矿机 使用计算资源尝试挖出已经挖出的区块。因此，自私 矿机 比其他 矿机 更有优势，最终可能会获得大部分挖矿奖励，从而对网络拥有更大的控制权。 我们如何防止自私挖矿攻击？ 自私挖矿会扣留区块链中的区块，使其完整性面临风险，并可能导致集中化。可以采取多种措施，其中一些措施已经采取，以减轻自私挖矿对网络的负面影响。让我们来看看为打击自私挖矿而提出的改进和补救措施。

1. 网络升级 提高网络对自私挖矿的抵抗力是打击自私挖矿的最佳策略之一。最好改变区块链协议来打击自私挖矿。例如， 矿机 更常使用 Ghost 协议来获取以太坊代币。该协议严格禁止自私挖矿，并向更早验证其区块的 矿机 支付更大的奖励。

2. 限制自私 矿机 限制自私 矿机 是解决这一问题的另一种措施。找到自私 矿机 并将其添加到阻止列表中将有助于实现这一目标。虽然这种策略有其用途，但并非万无一失。为了避免被发现， 矿机 可以切换身份或转移到不同的矿池。

3. 鼓励诚实挖矿 一些建议主张奖励诚实挖矿，以此作为打击自私挖矿的手段。防止自私挖矿的一种方法是对从事此类行为的 矿机 施加惩罚。

4. 矿机 之间的合作 促进 矿机 之间的合作有助于打击自私挖矿。例如，在将区块发布到网络之前， 矿机 可以决定共享这些区块。这有助于保证始终选择最长的链。

5. 降低挖矿奖励 另一个打击自私挖矿的有效策略是改变挖矿奖励。例如，如果发现区块的奖励减少， 矿机 可能不太愿意参与自私挖矿。同样，增加首先发布区块的奖励可能会阻止出于贪婪动机的挖矿。

6. 使用不同的共识算法 作为一种替代共识过程，权益证明 (PoS) 依靠验证者而不是 矿机 来生成新区块。验证者参与自私挖矿的动机较低，因为他们面临损失更多风险，因为他们的决定是基于他们在网络中的权益。然而，PoS 确实带来了一系列独特的困难，包括中心化的可能性和初始代币分配。
