What is Multisig and why does it matter?



MultiSig transactions, short for multi-signature, give several users access to a single wallet.

Cryptocurrency wallets have a public key, which is shared, and a private key, which is kept secret. Transactions must be signed with a users private key in order to verify ownership, and validate a transaction.


MULTIPLE KEYS
Multi-sig wallets have a public key with more than one private key.

M of N TRANSACTIONS
Requires multiple parties to be in agreement to complete a transaction.

ADVANCED SECURITY
Provides extra security, making coins safer from theft.


Multisig was first introduced in 2012, but did not become wide-spread until 2014.

A multisig wallet may only require a certain number of its multiple users to validate a transaction.

In 2014, less than 0.02% of BTC transactions were secured by
multisig. That number is now 10%.

Public addresses begin with the number 1,
Multisig addresses begin with the number 3.
