A blockchain code

1.

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin,

in essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

most blockchain public chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires that all accounts in the network need to deal with the accounting process. Distributed accounting has high security, low misoperation rate, political neutrality and correctness

however, blockchain technology embraces these features at the same time, sacrificing scalability, unable to meet the personalized supervision, and slightly insufficient in protecting data privacy. Moreover, with the increase of the number of ledger, the interaction delay will increase exponentially, that is to say, the more ledger in the blockchain network, the higher the delay

2. This should be a problem in two aspects: open source code refers to what we all know about this piece of code; As for the modification and destruction of the system, it should be the problem of system protection, so that people who want to modify and destroy can not enter. For example, there is a very valuable cultural relic in the glass window of a museum, which is on public exhibition. If you ask this question, someone will destroy or steal it.

3. For such a professional question, I suggest consulting the technical personnel or customer service of the underlying architecture of the software laikelib blockchain. Hope to adopt.
