区块链通过利用分布式记录全网所有交易信息，最终汇聚形成公开大账本”。其中每个区块链网络中的节点都具有记账的功能，每一个节点也都可以观察到整个总账。
The block chain eventually aggregates into an open large account by using distributed records of all transactions on the Internet.” Each node in the block chain network has a bookkeeping function and the entire ledger can be observed at each node.
区块链数据由每个节点共同维护，每个参与维护节点都能复制获得一份完整数据库的拷贝;同时，实现基础信息可追溯与不可删改。其协议与运作机制的关键在于标记时间戳”，全部节点每十分钟一起记账、确认信息，形成记录全网十分钟所有正确、无重复信息的账本数据库Block”，即为一个区块”。
Block chain data are maintained jointly by each node, each of which is involved in maintaining a copy of a complete database; at the same time, the basic information is realized retroactively and irrevocably. The key to its protocol and operating mechanism is a time stamp. All nodes are accounted for every 10 minutes, confirm the information, and form a 10-minute account database containing all correct and non-repeated information, which is a block.”
有效实现信用共享。《经济学人》的一篇文章，把区块链称为创建信任”的机器。这就说明区块链能够在技术层面建立去中心化的信任机制。在现实世界中的价值传递，往往需要基于一种信任机制来确权和记账，依赖于某个中心化的机构。例如，银行、证券交易所等，这种记账模式都是人们所熟知的。然而区块链却可以实现低成本的点对点价值传递，从而降低了信任的成本。
In the real world, value transfers often need to be based on a trust mechanism to confirm authority and record accounts, depending on a central institution. For example, banks, stock exchanges, etc., are well known.
