The project will also explore blockchain technology to make meat, fish, vegetables and fruits safe and traceable. At present, the Easy Clean Vegetables-Guaranteed Supply, Stable Prices and Vegetable Basket Trunk Project is a "people's project" that has grown during the anti-epidemic and supply guarantee period. In the future, it will serve as a "new livelihood project" and "new infrastructure project" in the post-anti-epidemic period.

mining

1. Biyin Mining Pool: S19 series mining machines can fully cope with halving and the current payback period is about 500 days

Regarding the "Bitmain S19 mining machine on sale", the CoinIn Mining Pool stated that the sale of the S19 mining machine has little impact on the market at present, and there is no spot stock yet. This machine can cope with the halving without any problem. Because its energy efficiency ratio is currently the lowest, that is to say, S19 will definitely be the last batch of machines to be shut down, and it should be considered the safest machine at present. Under the condition that the price of the currency remains unchanged and the difficulty remains unchanged, the payback period of the S19 mining machine is about 500 days, including the upcoming halving event, but at present, the difficulty will definitely decrease in the next cycle. If the computing power of the entire network decreases by 30%, the payback time will be relatively reduced by 30%. In addition, the expected decrease in computing power after halving and the reduction in difficulty will also speed up the payback. As for the fact that the official website was sold out as soon as it was sold out, it was mainly due to the rush to buy by retail investors. Large investors will prepare funds in advance at the manufacturer and take the goods directly.

2. Gyro Informal Talks | F2Pool CMO: When the price of coins falls, electricity costs become a key factor in the survival of mining machines

On March 25, F2Pool CMO JeSSica was a guest in the "Gyro Informal Talks" live broadcast room. When talking about "how miners survive after the price of the currency falls", she said that this month the total network computing power has been adjusted from the highest 130E to the current 100E, mainly S9 mining machines. There is no profit at the dry season electricity price. S9, A8, and A9 entered the shutdown state in advance before the halving. At present, some miners are migrating machines and preparing to start mining in the flood season. If the price of the currency is above 8,000 US dollars after the halving, the old machines will still have some mining profits according to the electricity fee in the flood season plus frequency reduction. The three core factors that determine whether Bitcoin mining is profitable are the currency price, computing power and electricity fee. When the price of Bitcoin is in a downward channel, electricity fee becomes a key factor in the survival of mining machines. Whoever has a lower electricity price resource and a lower proportion of electricity fee will have a greater advantage in mining and will be more likely to survive.

3. MRI Index shows that miners have recently sold more Bitcoin than they mined

In the 13 days ending March 25, bitcoin rose from $3,867 to $7,000, according to CoinDesk's Bitcoin Price Index. However, the MRI Index of miner inventory data created by crypto market data firm ByteTree shows that miners sold more bitcoin than they mined during 81% of the recovery rally. The 21-day rolling MRI has remained above $100 throughout the recent recovery from lows below $4,000. An MRI above 100 indicates that miners are selling more than they are mining and are reducing inventories; an MRI below 100 indicates that miners are selling less than they are mining and are accumulating inventories. As prices continue to rise, there is ample demand for the bitcoin that miners are providing to the market.

4. Gyro Informal Talks | Yu Wei, founder of Zhijian Xinyun: After the halving, the price of old mining machines will drop sharply, and the price of new mining machines will not drop much

On March 25, Yu Wei, founder of Zhijian Xinyun, was a guest in the "Gyro Informal Talks" live broadcast room. When asked whether the price of mining machines will fall after the halving, he said that the price of mining machines will definitely fall after the halving. It should be mentioned here that the old mining machines will definitely fall sharply, and the new mining machines may not have a larger drop, because the new machines have a cost and output problem. This year is a year of amplified 5G chip production, and digital computing chips are an unstable output, so Samsung and TSMC will not put out a large amount of production capacity to support digital currency chips. If the price of the currency rises and the output increases, the cost will naturally fall. According to the current global economic situation and currency price situation, the new machine will not fall too much after the halving.

DeFi

1. Cross-chain DeFi platform Kava integrates oracle Band

Kava, a cross-chain DeFi platform supported by Binance and Ripple, has integrated the decentralized oracle protocol Band Protocol.

The Kava oracle solution roadmap has revealed that Kava currently uses an oracle whitelist mechanism to collectively publish the price of each asset on the blockchain. During the mining of each block, the aggregate price obtained by the oracle and the median price of each asset will become the asset price in the entire CDP system.

4. Norwegian exchange NBX expects to launch DeFi-related business this spring

Norwegian crypto exchange NBX has close ties to Norwegian Air. However, due to the current crisis in the airline industry, Norwegian Air's stock price has plummeted by around 80% since February. Today, the Financial Times reported that the company is considering seeking government aid. Although Norwegian Air is not a shareholder of NBX, its importance as an initial customer of NBX's newly launched crypto ticketing solution is self-evident.

When asked if NBX has plans to further develop the exchange without Norwegian Air's business, NBX CEO Stig Kjos-Mathiesen said he would not comment on the company's current situation, but stressed that the company's payment solutions are only a "small part" of NBX's business. Mathiesen said: "Norwegian Air is a pilot customer of NBX, but its intention has always been to provide commercial payment solutions in several industries."

In addition, Mathiesen also said: "DeFi business is now a focus area for the company. The most important thing for NBX is to provide DeFi products to customers. Our exchange is an important part of making it simple and seamless for customers to move between different DeFi protocols and networks. This has been our roadmap for the past year and we hope to launch it in the spring." (Cryptonews)
