Describe blockchain Technology

1. I have summarized the following two characteristics:
1. Block chain technology is a decentralized consensus mechanism to maintain a complete, distributed and tamper proof ledger database. It can enable the participants in the blockchain to achieve a unified ledger system without establishing a trust relationship. 2. Renren blockchain technology service platform does not need to develop one click to create its own blockchain system to quickly build blockchain infrastructure; One click to complete the development and deployment of blockchain applications; To provide your customers with open, transparent and credible services.

2. I remember reading the relevant content on the official wechat of remittance world, which said that "blockchain" is the proct of peer-to-peer (or peer-to-peer) e-cash system, which can essentially replace the central bank's currency issuance, payment and settlement functions. But you can check the relevant information again to confirm the information.
