However this transaction now needs to be validated and added to a block of the blockchain. The blockchain is a chain of blocks, and a new block is added every ~10min. We will explain how miners create new blocks, why it takes roughly 10 minutes to mine a new block, and why validation of a transaction takes on average 60 minutes if everything goes well (=6*10 minutes). Miners are currently rewarded by 12.5 BTC by block (it used to be 25 BTC/block, now is 12.5 BTC/block until 2020, then afterwards 6.25 BTC/block. This halving continues until 2110–40, when 21 million bitcoins will have been mined.) A block consists of 2 things: - an easy part: a list of transactions since the last block was found, this is to validate the transactions. - a difficult part: a code that proves the identity of the miner that mined it (so that the network can award him the 12.5 ...
