Genesis blocks hold a symbolism that’s almost spiritual. They represent the birth of a new cryptocurrency, and when that currency flourishes, its foundation stone – the maiden block to have been mined – is referenced reverentially. Ethereum’s first address is a memorable one: 0x followed by 40 zeroes. It’s also a dangerous one that has been the unintended recipient of $6 million in ether and over $500 million in ERC20 tokens.
