Single-sig, multi-sig account

In Mitum, there are two types of accounts: multi-signature (multiSig) accounts and single-signature (singleSig) accounts. The primary distinction between these two types of accounts lies in their creation methods.

singleSig account is created by mitum-currency-transfer-operation operation.

While, multiSig account is created by mitum-currency-create-account-operation or mitum-currency-create-contract-account-operation operation.

Methods that generate singleSig account:

• account.createAccount

• account.createWallet

• account.createBatchWallet

• account.key + currency.transfer

Methods that generate multiSig account:

• account.createMultiSig

• contract.createAccount

• contract.createWallet

Currently, Mitum allows the creation of multiSig accounts even with just one account, which differs from the typical multiSig accounts derived from multiple public keys.

While Mitum offers the multiSig accounts in the conventional sense as well, the concept of multiSig accounts in Mitum can be considered as more "extended."

You don't need to dwell too deeply on this. The differences observed at the Mitum network between singleSig and multiSig accounts created through the aforementioned methods are summarized in the table below.
