Central Bank of Tunisia and Afghanistan can create crypto bonds to attract investment

Published

on

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. ”
