Blockchain is a distributed database that allows for secure, transparent and tamper-proof storage and transfer of data. By eliminating the need for a third party to verify transactions, blockchain provides a more efficient and secure way to conduct business.
How does blockchain work?
Blockchain is a shared digital ledger that records transactions in a secure, tamper-proof way. When a transaction is made, it is recorded on the ledger and shared with all the computers in the network. Each computer in the network then verifies the transaction and adds it to the chain, creating an immutable record of all transactions that can be traced back to the genesis block.
What are the benefits of blockchain?
Blockchain offers a number of advantages over traditional databases, including increased security, transparency, and efficiency.
