Hi, I'm just looking around and trying to compile & run ckb on arm64 just for fun, and noticed that ckb-system-scripts fails to compile because it needs this nervosnetwork/faster-hex#9
Should I make a PR to bump this line? https://github.com/nervosnetwork/ckb-system-scripts/blob/master/Cargo.toml#L19
We can migrate existing test suites for the crypto algorithms. Add use fuzz test to discover possible bugs.

In Bitcoin, a multisign script is written like this:
M <Public Key 1> <Public Key 2> ... <Public Key N> N CHECKMULTISIG
One can embed this script in a TX's output, and provide enough legal signatures to unlock. However, the most popular multisign method in Bitcoin is P2SH. P2SH allows users embed the Hash160 of multisign script in an UTXO, and provide original script and signatures to unlock it later.
P2SH reduces the script size to a 20bytes hash, and thus it is easy to be encoded to a multisign address.
Current multisign script on CKB is plain mode, which means the lock script has to embed and exposure all of the PKs. It costs more capacity, lack of security and privacy, and hard to be encoded to a short address.
So i suggest we follow Bitcoin's P2SH multisign method. Lock script only includes the script hash, and we use witness to provide full script.
int main(argc, args[]) {
if (argc == 2) {
// do single signature verification.
} else if (argc == 3) {
multisign_PK_hash = args[1]
multisign_script = args[2]
signers = []
PK_hash = hash()
for (signature in witness) {
PK = signature.recover()
PK_hash.append(PK)
signers.add(PK)
}
if (PK_hash != multisign_PK_hash) return -1;
return check_multisign_script(signers, multisign_script)
}
}
Keep multisign_script simple, like "2/3",and "3/5!1!4". Where "n/m" means at least n of m signature should be provided, and "!i" means one of signature must match the i-th PK.
