Google verifier and blockchain Technology

1. Google's authentication program can only read the QR code generated by Google's two authentication systems, and other programs may not be able to read it.

2. According to the learning order, it will be more systematic and efficient:
(1) establish the outline understanding of blockchain through more popular reading materials
(2) get to know the elder: bitcoin
(3) learning: Ethereum and EOS
(4) learn several projects that you are interested in and have a thorough understanding of at least one project white paper
(5) expand learning through relevant media channels, and constantly enrich their own relevant knowledge

in the eyes of many newcomers, blockchain is almost equal to bitcoin, so it is necessary to understand the overview of blockchain first, just like taking a book and looking at the directory first to know what it contains, rather than reading the first page. After the first step of learning, we have a vague concept of bitcoin, blockchain, exchange and wallet. Hands on practice is the best way to improve learning motivation and efficiency. It can also put forward more practical questions in practice and find answers with questions. The learning effect will be better. Therefore:

(1) choose an exchange, such as: huobi.pro, okex.com, BIGone, otcbtc, etc., register an account. In this process, we need to pay attention to the use of Google verifier
(2) buy a little bit, such as 0.03 bitcoin. It is recommended to buy it through C2C OTC trading and usdt trading pair, and be familiar with the two ways of purchasing
(3) download and install wallets, such as Bitian, and pay attention to the storage of mnemonic words
(4) transfer a bit of bitcoin from the exchange to the wallet

after completing the operation of the above process, you will have personal experience of the exchange, wallet, private key, OTC trading, etc<
