Bitcoin Block Size
Bitcoin blocks are collections of records of transactions which take place in the Bitcoin network, which are added by miners to the end of the Blockchain about every ten minutes. Currently, the size of any particular block is limited to 1 megabyte, which means that if a miner submits a block of a larger size to the network, the latter will reject it. The limited block size restricts the number of transactions which can be recorded in every block. There are proposals in the Bitcoin community to increase the block size limit. There are strong arguments both for and against the increase, so it remains the topic of heated debate.
