The Blockchain

A blockchain is a digitised, decentralised, public ledger of all cryptocurrency transactions. Constantly growing as ‘completed’ blocks (the most recent transactions) are recorded and added to it in chronological order, it allows market participants to keep track of digital currency transactions without central record keeping. Each node (a computer connected to the network) gets a copy of the blockchain, which is downloaded automatically.
in the case of blockchain technology, private key cryptography provides a powerful ownership tool that fulfills authentication requirements. Possession of a private key is ownership. It also spares a person from having to share more personal information than they would need to for an exchange, leaving them exposed to hackers.
Finding and publishing new blocks is what Bitcoin miners do to earn bitcoins. Whenever a new block is broadcast, approximately every 10 minutes, a quantity of bitcoins is received by the miner who solved that block. Bitcoin miners keep the network secure, and this is how they are rewarded. This system ensures that all transactions are valid, and keeps the bitcoin network secure from fraud.
Distributed ledger technology has great potential to revolutionize the way governments, institutions, and corporate work. It can help governments in tax collection, issuance of passports, record land registries, licenses and outlay of social security benefits as well as voting procedures. The technology is making waves in industries such as finance; music and entertainment; diamond and precious assets; artwork; supply chains of various commodities; and more. While the distributed ledger technology has multiple advantages, it’s in a nascent stage and is still being explored to adopt in the best possible ways. The future of ledgers is decentralised.
