 **Abstract.**  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 double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, they'll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.

 永久線性增長模型降低了在比特幣中出現的財富過於集中的風險，並且給予了活在當下和將來的人公平的機會去獲取貨幣，同時保持了對獲取和持有以太幣的激勵，因為長期來看“貨幣供應增長率”是趨於零的。我們還推斷，隨著時間流逝總會發生因為粗心和死亡等原因帶來的幣的遺失，假設幣的遺失是每年貨幣供應量的一個固定比例，則最終總的流通中的貨幣供應量會穩定在一個等於年貨幣發行量除以遺失率的值上（例如，當遺失率為1%時，當供應量達到30x時，每年有0.3x被挖出同時有0.3x丟失，達到一個均衡）。
