Is a distributed database that has the ability to manage an ever-increasing list of named records (blocks). Each block has a timestamp and a link to the previous cluster. The cluster string is designed to preserve and prevent the data stored in it, meaning that when you store information in the cluster, you can not later modify that information.

The cluster chain is safe by design and is an example of distributed distributed computing system with high Byzantine error tolerance. The cluster chain thus allows for a decentralized system of consensus. These features allow the cluster chain to record events, addresses, medical records, and other activity management records, identity management, transaction processing, and source verification. Such a system has profound implications for the global economic system, including the removal of large-scale intermediaries and the completion of commercial transactions without intermediaries (such as banks), which also affects the course of global trade as we know it today.

In 2008, Satoshi Nakamoto put forward the concept of the block series and then wrote in the following year an essential part of the digital currency code of Betcuen, which acts as a public ledger for all cash transfers. The cluster chain database is managed in an independent manner because of its reliance on the Ned-Land network and time stamp servers distributed around the world. The use of the mass chain in the design of the currency system made the latter the first digital currency to avoid the problem of double spending (spending the same cash amount in two different transactions).
