🤝BLS multisig transactions
Useful links
Shortly, the typical keypair looks like this:
{
"privateKey":"caad28a7da57fb28879bfdd886714629e4152553a28540caed6f51531f5af61a",
"pubKey":"7QMxLg6GJwQYjc8B2WBEvaQq3TfeBhgBqHGneFu43oLfwhovrPGykbkUGe94FacSuG"
}48-bytes Base58 ecoded public key(used as address)
32-bytes hexadecimal private key
96-bytes Base64 encoded signature
