Announcing RIF Multisig!

What does multisig mean?

The term "multisig" stands for "multi-signature" and it's used to describe accounts associated with more than one private key. The account is created with a list of owners and a policy `m-out-of-n` when transactions are approved by at least m owners, they can be executed.

In blockchain each transaction involves the usage of public-key signature; each blockchain participant owns a private/public key pair. The participants use the private keys to sign a transaction and all other participants can verify that signature using the signer's public key.

With a multisig account, each transaction requires the signature of many accounts before being executed. One participant (who is among the multisig account owners) can start the transaction, but only when the other owners approve that transaction, it will be executed.


The multisig account eliminates the single point of failure in case of attacks and it allows the implementation of a variety of use cases where one or many parties are involved. Here below some examples.

  • Redundancy: if a user loses the key, the funds are not lost because the other keys can still be used.
  • 2FA (two-factor authentication): a single user can have both a web wallet and a mobile wallet associated with a multisig account, policy 2-of-2.
  • Departments approval: two departments must approve each transaction before being published, policy 2-of-2.
  • Parents' saving account: a kid can spend money only with the approval of either parent.
