Block is a permanently recorded file in the Dcoin network that contains information about transactions completed. Block is a partial or full record of recent transactions that weren’t yet recorded in previous blocks. In almost every case blocks are added to the end of the chain called block chain, which contains all transactions. When a block is added to the end of the chain, it cannot be amended. Block can be added to the block chain by a miner determined using the special algorithm.
