A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the ...
Commerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, sinc...
We define an electronic coin as a chain of digital signatures. Each owner transfers the coin to the next by digitally signing a hash of the previous transaction and the public key of the next owner and adding these to the end of the coin. A payee can verify the signatures to verify the chain of ownership. The problem of course is the payee can’t ve...
The solution we propose begins with a timestamp server. A timestamp server works by taking a hash of a block of items to be timestamped and widely publishing the hash, such as in a newspaper or Usenet post. The timestamp proves that the data must have existed at the time, obviously, in order to get into the hash. Each timestamp includes the previou...
To implement a distributed timestamp server on a peer-to-peer basis, we will need to use a proof-of-work system similar to Adam Back’s Hashcash, rather than newspaper or Usenet posts. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is expon...
The steps to run the network are as follows: 1. New transactions are broadcast to all nodes. 2. Each node collects new transactions into a block.3.Each node works on finding a difficult proof-of-work for its block. 3. When a node finds a proof-of-work, it broadcasts the block to all nodes. 4. Nodes accept the block only if all transactions in it ar...
By convention, the first transaction in a block is a special transaction that starts a new coin owned by the creator of the block. This adds an incentive for nodes to support the network, and provides a way to initially distribute coins into circulation, since there is no central authority to issue them. The steady addition of a constant of amount ...
Once the latest transaction in a coin is buried under enough blocks, the spent transactions before it can be discarded to save disk space. To facilitate this without breaking the block’s hash, transactions are hashed in a Merkle Tree , with only the root included in the block’s hash. Old blocks can then be compacted by stubbing off branches of the ...
It is possible to verify payments without running a full network node. A user only needs to keep a copy of the block headers of the longest proof-of-work chain, which he can get by querying network nodes until he’s convinced he has the longest chain, and obtain the Merkle branch linking the transaction to the block it’s timestamped in. He can’t che...
Although it would be possible to handle coins individually, it would be unwieldy to make a separate transaction for every cent in a transfer. To allow value to be split and combined, transactions contain multiple inputs and outputs. Normally there will be either a single input from a larger previous transaction or multiple inputs combining smaller ...

比特币挖矿的简化概述如下： 人们通过应用计算能力参与一种称为“工作量证明”（PoW）的过程，以竞争获得比特币奖励。 之所以这样命名，是因为只有那些证明自己已经投入了足够资源（工作）的参与者（矿工）才有机会赢得奖励。 大约每10分钟，奖励会分发给一个胜出的“矿工”。 奖励有两部分 -> (1) “区块奖励”，即新铸造的比特币。 在写作本文时，区块奖励设定为6.25比特币（但从2024年5月初开始，奖励将减半，之后每四年再减半，依此类推）。 (2) 当前区块内所有交易相关的费用。 希望进行交易的终端用户必须为拟议的交易附加一笔费用，以激励矿工将其包含在下一个区块中。 目录. 为什么需要比特币挖矿？ 什么是工作证明，为什么它是必要的？ 比特币挖矿是如何工作的？ 什么是比特币的哈希算法？
