According to Science Daily, the most significant geological event that happens in ocean trenches is the gradual subduction of the Earth's crust down into its mantle. This process takes tens of...
A blockchain â originally block chain â is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block contains typically a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data.
The series of blocks is called the blockchain. The blockchain is like your checkbook register or a general ledger of transactions. The way that Bitcoin Mining secures the blockchain makes that ledger tamper-proof and immutable. Each block once made into a block will be verified by nodes on the Bitcoin network.
