FDV与市值的区别. 市值是通过将当前代币价格乘以代币的流通供应量来计算的。 市值 = 流通供应量 x 代币价格. FDV考虑了包括未流通代币在内的总供应量。 FDV = 总供应量 x 代币价格. 当所有代币都在流通时，FDV和市值将是相同的。 然而，对于许多项目来说，流通供应量只是总供应量的一部分，使得FDV成为比市值更前瞻性的指标。 它也为项目当前估值提供了现实检查。 为什么FDV优于市值. FDV因多种原因成为首选指标。 它通过考虑所有未来将进入流通的代币，提供了项目潜在价值的更全面视图，从而使估值具有前瞻性。 投资者可以通过将当前市值与FDV进行比较，更好地评估项目是被低估还是高估，从而做出更明智的投资决策。 此外，FDV有助于风险管理，帮助投资者理解未来代币释放对市场的影响。
2011年4月26日 · Satoshi’s Last Email. This email, or email excerpt, was quoted by Gavin Andresen in an interview in 2014. I wish you wouldn’t keep talking about me as a mysterious shadowy figure, the press just turns that into a pirate currency angle.

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 ...
