Essentially, a 256-bit hexadecimal number is used to encrypt transaction data that is stored in a block.

all time high, and it is

Each new block has a value called a “target hash.” In order to win the right to fill the next block, miners need to produce a hash that is lower than or equal to the numeric value of the ‘target’ hash. Since hashes are completely random, it’s just a matter of trial and error until one miner is successful. No more bitcoin can be created and units of bitcoin cannot be destroyed.

When burned, coal and natural gas emit greenhouse gases, which heat the Earth and change the climate. As of 2022, such bitcoin mining is estimated to be responsible for 0.1% of world greenhouse gas emissions. A second environmental effect is the air pollution caused by coal-fired electricity generation, and a third is the e-waste due to the short life expectancy of bitcoin-mining equipment.

Up until the final Bitcoin is GMT mined in roughly 2140, the rewards will continue to decrease in this manner every four years. Overall, miners have a queued list of transactions they have to validate. They take one transaction and all attempt to verify it at the same time. Essentially, miners have to solve a nonce (a four-byte number) included in the block header.

The two blockchains operated simultaneously for six hours, each with its own version of the transaction history from the moment of the split.
