Checklist: Night photography. 1: Switch your camera to Manual mode by turning the mode dial to âMâ. 2: Choose the smallest f-number available and a relatively long shutter speed to record the lights. One second is a good starting point and most cameras indicate seconds using double quotes, so look for 1â.
Bitcoin mining is the processing of transactions on the Bitcoin network and securing them into the blockchain. Each set of transactions that are processed is a block. The block is secured by the miners. Miners do this by creating a hash that is created from the transactions in the block.
I want to keep this simple and as we are talking about the bitcoin blockchain for now (There are others) And their mining process differs, some good some bad. so please keep this mind. I will quickly try to explain the mining aspect which in my opinion is the magic that makes a blockchain.
