The very first block in a blockchain network that is hard-coded into the blockchain code.
A small denomination of ETH. 1 ETH = 1,000,000,000 Gwei.
Output data that is the result of using a hash function. With regards to blockchain, the output data is the result of using a deterministic hash function; a function that ensures the same input data will always result in the same output data.
Satoshi Nakamoto created Bitcoin with a finite supply of 21 million Bitcoin – making it a scarce commodity. Roughly every 4 years (210,000 blocks * 10 minute average creation time = 4 years), Bitcoin undergoes a process called the halving where the reward rate for mining a block is reduced by half (50%)
