1. Technical language

Python and Go are two technical languages that are mentioned in recruitment by many companies. Need to prioritize learning. Moreover, these two languages also have great applications in technical directions other than blockchain. For example, Go is used in the background construction of large-scale concurrent systems, and Python is used in the construction of artificial intelligence systems. So learning these two languages is a priority.

2. Technical framework

Master one or more of Bitcoin, ETH and Hyperledger.

Needless to say about BTC, the bottom layer is written in C++. A large number of currency projects, such as Litecoin, Dash, Monero, zcash, etc., all use Bitcoin technology for secondary development.

ETH is the representative of blockchain 2.0, and various application Dapps can be built on the ETH network. Nowadays, a large number of application blockchain projects are developed using the ETH platform.

Hyperledger fabric is a blockchain development platform promoted by IBM. It is mainly used for the development of alliance chains. It is currently the most popular alliance chain development platform.

3. Algorithm

POW (Proof of Work Algorithm), POS (Proof of Stake Algorithm), PBFT (Byzantine Fault Tolerance Algorithm), etc. are all important components of the cryptography part of the blockchain. A full understanding of these algorithms will help you participate in the blockchain You can have a better understanding of the cryptography part when developing the underlying project. Cryptography was not a modern subject before, and most computer practitioners did not have knowledge of cryptography.

As long as you can master the above three things, you can become an excellent blockchain development talent. If you master the first one, you will have the basic ability to participate in blockchain development.
