On the evening of February 23, the People's Bank of China officially released the Financial Industry Standards for "Specifications on the Security of Financial Distributed Ledger Technology", which is applicable to institutions engaged in the construction of distributed ledger systems or service operations in the financial field, and provides large-scale applications for distributed ledger technology. Business support capabilities and information security risk constraint capabilities have a benign promotion effect on industrial applications. However, blockchain technology is still in the early stages of development and many issues have not yet been resolved. Therefore, the Digital Currency Research Institute of the Central Bank stated in the latest research that it is currently not recommended to transform traditional payment systems based on blockchain.

Blockchain and physical applications

The new crown "war epidemic" has not ended, and the blockchain has not withdrawn. More blockchain applications are being supported.

Third, technical direction

In 2020, Ethereum will not only have 2.0, but also welcome ProgPow. Although V thinks that after Ethereum welcomes PoS, ProgPoW will appear redundant and there is no need to consume resources. But Ethereum PoS does not have a clear date after all, and Ethereum core developers seem to want to implement ProgPoW in the short term.

V. Mining

Now that there are about 3 months left before Bitcoin halved, there is no doubt that miners are most affected by the halving. If the price of Bitcoin is still at the current price level after halving, this will cause huge losses to the mining . If Bitcoin continues to stagnate, then this panic may worsen with the halving, and mining may be facing its biggest turning point in years.

Seven, central bank digital currency and Libra

Sweden took the lead and started testing the central bank's digital currency, and it is even expected to become the first country to eat crabs. In 2020, the central bank's digital currency has received great attention, and important progress is expected, and it is even expected to see the birth of the first central bank digital currency. Libra is also developing steadily. The initial development path seems to be too aggressive, which has led to regulatory resistance. Now Libra seems to intend to start with the US dollar and anchor a single currency, which may make Libra's road more stable.

Halving = new high? Many people are predicting whether the upcoming halving of Bitcoin will drive the market up.

Prediction is easy, but in the end Bitcoin will only take time to tell us.

Analyst: Bitcoin inflation will be lower than most central banks after halving, and its price will easily rise to $ 200,000 in two years
