Enterprise alliance chain system development | detailed explanation of the development of blockchain public chain traceability system

Blockchain has become the gold that major well-known companies are vying for. Now the government has also participated in it. Many companies are facing the question of "how much is the development of blockchain public chain". In this regard, it can be seen that the blockchain is How important is it? Now that people who have not invested in blockchain have appeared in the market, it is not the perception of investors at all.
Decentralized applications (DAPP) need to be built on a certain underlying chain. Different business scenarios have different requirements for the performance and consensus mechanism of the underlying public chain, and a certain application even needs to build its own underlying chain (including private chain, alliance chain, and public chain, etc.).
Introduction to the development process of the blockchain public chain:
Bitcoin is the first-generation public chain on the blockchain. At the beginning of the design, Bitcoin was positioned as a payment tool and could only carry out value transmission. As a result, Satoshi Nakamoto has significantly deleted many script instructions, so its security is extremely high. But Bitcoin's scripting language is Turing incomplete, cannot execute loop statements, and has poor scalability. Many advanced applications cannot be built on Bitcoin scripts.
Ethereum is the second-generation public chain on the blockchain. It is a public blockchain platform with Turing-complete scripts and is called the "world computer". In addition to value transfer, developers can also create any smart contract on Ethereum. Ethereum has expanded blockchain commercial channels through smart contracts, such as the issuance of tokens for many blockchain projects, smart contract development, and the development of decentralized DAPPs. Currently, there are more than 1,000 DAPPs based on Ethereum.
The third-generation public chain is positioned to be commercially available on a large scale and is associated with actual assets and real value to promote the development of the real economy. The public chain projects currently competing in the blockchain 3.0 era include EOS, Cardano, Bytom, etc., but most of these public chain projects are in the theoretical demonstration and testing stage, and a few projects that have completed the development of the main chain are still in the early exploration stage.
Currently other well-known public chains include Cardano, NEO, QTUM, BYTOM, Aeternity, Aelf, Zilliqa, Metropolis, etc. At present, Cobo Wallet already supports more than 20 kinds of blockchain assets including ETH, EOS, TRX, QTUM, AE and other main chains, and more than 500 tokens.
