What is Blockchain Technology?
Blockchain is a distributed digital ledger that records transactions across thousands of computers worldwide. Once registered, these transactions cannot be altered, making blockchain highly secure, transparent, and cost-effective. This technology eliminates the need for third-party verification by using consensus mechanisms to validate transactions.
