How does Bitcoin work?

The blockchain is a shared public ledger on which the entire Bitcoin network relies. It allows Bitcoin wallets to calculate their spendable balance so that new transactions can be verified. All confirmed transactions are included in the block chain. The integrity and the chronological order of the block record are enforced with cryptography.

Bitcoin is a virtual currency that allows people to transfer value between Bitcoin wallets. A private key or seed is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature prevents the transaction from being altered by anybody once it has been issued.

Mining is a distributed consensus system that is used to confirm pending transactions by including them in the block chain. It enforces chronological order, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict rules.

How will Blockchain boost trade in Africa?

Despite a regional economic slowdown in 2020, over a dozen African countries grew last year. Complicated trade rules and lengthy border processes stifle African economies. These long-standing issues need creative solutions. Blockchain is becoming more practical and scalable in developing markets. It has just opened a regulatory "sandbox" for innovative blockchain-based goods in Ghana. Standard Bank has joined Marco Polo, a trade financing network. Here are four ways blockchain may help African trade: 1. Customs The AU-EU trade deal is still in its infancy. Traditional customs bureaucracy prevents SMEs from joining global trade networks. This procedure can be automated and simplified, saving time and money. 2. Traceability Tracking cross-border goods correctly is critical for standard and certification verification. Already, blockchain is allowing ethical supply chains for a variety of African goods. Its open-source but secure design makes certificates easy to issue and verify...
