內容簡介
The blockchain technology is probably the greatest human invention after the internet. Simply put, the blockchain technology is a form of a distributed ledger that is decentralized and public and can record transactions with a very high level of security. All the records in the blockchain are called blocks, and each of them is linked to the previous one with a hash pointer and is securely stored with cryptography. This technology is revolutionary because every transaction is recorded across a network of multiple computers in the net. This way, no record can be altered or modified without changing the other blocks. Since the blockchain technology is so decentralized, it is free from control or influence of any central authority. Even the founder or developer of a blockchain cannot change the records without the consent of or notice to all the other users. The blockchain technology is still in its early days, but it's already clear that it has the potential to change our financial system forever.
