EthereumIsValidAddress returns whether the given string is a valid ethereum address.

HashStrToHex hash a string returns a hex encoded string of the result.

HashToHex hash the input bytes and returns a hex encoded string of the result.

PoW calculates proof of work given block hash, transaction hash, target difficulty and a hash function.

Verify checks that the hash with the given nonce results in the target difficulty.
