Published

The heads of central banks of Afghanistan and Tunisia said that their countries are considering the possibility of issuing sovereign cryptocurrency bonds. Officials reported this at the annual Spring Meetings of the Board of Governors of the International Monetary Fund and the World Bank Group in Washington.

Governor of the Central Bank of Afghanistan, Khalil Sediq, said they are seriously considering crypto bonds as a tool to attract the $ 5.8 billion private investment needed by the country's mining, energy and agricultural sectors.

Since the country is limited in opportunities for concessional lending due to the ongoing internal armed conflict, the issue could be the issue of bonds and futures for metals, said Sedik. The country hopes to use for this its reserves of lithium, estimated at more than $ 3 trillion.

The head of the Central Bank of Tunisia, Marouane El Abassi, in turn, said that the country has already established a working group, which is also seriously studying the issue of issuing sovereign bonds to Bitcoin . He recalled that Tunisia was one of the first countries in the world to issue electronic currency, an e-dinar, in which payments are received by national mail.

How do transactions occur in the Bitcoin network? The whole cycle from start to finish

Published

on

Bitcoin (BTC) and its complexity have become a concept that many cryptocurrency users have been trying to understand since its inception. In his latest video, the famous Bitcoin enthusiast Andreas Antonopoulos and the author of the book “Mastering Bitcoin,” spoke about the life cycle of a Bitcoin transaction with a wallet from start to finish.

Antonopoulos said that since the transaction was sent from the wallet for confirmation to the Bitcoin network , the wallet creates a transaction, accumulating BTC in the user's wallet and assigning addresses. Then the user's wallet transfers the transaction information to one of the many nodes to which it is connected, from where it can be sent to “1, 2 or even 8 other nodes”.

“Then the transaction is transferred to other nodes, which can be mining nodes, e-commerce payment gateways and other options. Each of these nodes will receive a transaction from yours, and each will verify each transaction. When nodes receive transactions, they do not know whether it was created by you or was redirected, and therefore each of these transactions must be checked individually. ”

Then Antonopoulos said that if all the nodes are checked, i.e. if the payment details are correct and it is confirmed that there were no double costs in the blockchain, then the transaction information will be sent to every other node.

“As soon as a transaction reaches the mining pool , it enters the pool of unconfirmed transactions, for example, a basket in which all unconfirmed data is stored. In another way it is called mempul. The information in individual memoplahs may coincide by 99%, but there will never be complete similarity. ”

According to the expert, the memory also serves to submit the transaction to the BTC miner to add a new block, after which the race is turned on for the next block. As a rule, miners have to build a block, and then solve it with the help of Proof-of-Work , making it ultimately confirmed.

Once the unit is ready, the information will be sent mayningovomu equipment to solve the problem in this particular block, and probably after the "billion hashes" miners will block.

“As soon as PoW is resolved, the mining node will return the node back in the same way as it received. The nodes check the block on the way back, and as soon as all the nodes confirm its validity, the user's wallet will know about the confirmation of the transaction. This is the full life cycle of a transaction. ”

At the upcoming bull rally, Bitcoin (BTC) capitalization will exceed $ 1 trillion

Published

on

Chris Berniske, who previously led cryptocurrency investments in ARK Invest and is now a partner in Placeholder, a $ 150 million asset management venture fund, said that Bitcoin's market capitalization will exceed $ 1 trillion. in the next bull market:

“Estimates of the top 10 cryptoactive assets at the end of each year give me the idea that only Bitcoin will reach $ 1 trillion. in the next bull market. ”

Recall that during the cryptocurrency boom at the end of 2017, when the price of Bitcoin reached $ 20,000, the market capitalization of the entire crypto market reached a maximum of $ 813 billion. If the capitalization of only one Bitcoin exceeds $ 1 trillion, it will trade at a rate above $ 40,000.

How can bitcoin reach a market capitalization of $ 1 trillion?

Like gold and other commodities, Bitcoin must become a recognized store of value with a developed infrastructure in order to cope with a huge influx of capital. In the near future, the development of this infrastructure may take several years.

In a Fortune interview last year for the New York Stock Exchange, Jeff Sprecher said that buying Bitcoin today is quite problematic for institutional investors.

“Bitcoin does not have a good market structure. Even for Bitcoin, different markets publish a lot of different prices. And you can pay up to 6% of the spread to exchange dollars for bitcoins, which means that bitcoin must grow by as much as 6% so that you can break even. ”

Many investors, including billionaire Mike Novograz, believe that those that lead Bitcoin to a trillion-dollar market capitalization are likely to be institutional investors. In an interview with Bloomberg, Novograz said:

“Maybe one of the fearless pension funds, one of the market leaders, will say:“ you know what? We have custodial services, Goldman Sachs participates, Bloomberg has an index by which I can track results. ” And they will buy. Following them, others will also start shopping. There will be a similar FOMO, which we have already seen among retail investors, only at the institutional level. ”

The imminent arrival of institutional investors to the cryptocurrency market was mentioned as early as 2017. According to a survey conducted by TRADE Crypto in partnership with BitGo, 94% of the 150 surveyed endowments in the US have already invested in the cryptocurrency market.

Morgan Creek Digital, the first US pension fund that invested in cryptocurrency, said that 66% of investments in cryystocurrency products of Grayscale come from institutional investors .
