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.
This article is about the computer input/output technique. For the process scheduling concept, see Blocking (computing). In computing (specifically data transmission and data storage), a block, sometimes called a physical record, is a sequence of bytes or bits, usually containing some whole number of records, having a maximum length, a block size. Data thus structured are said to be blocked.
