Sig3 Simplifies Multisig Bitcoin Transactions
Sig3, a Bitcoin startup which launched on September 21st, is looking to simplify multisignature (multisig) transactions through automated co-sign policies. Multisignature Bitcoin addresses require more than one key to authorize a transaction. In the case of Sig3, at least two keys must verify the transaction. This may be the user and Sig3, or multiple users or user keys. Through Sig3, users select conditional policies which must be met before a transaction is approved. Example rules include auto-approving by date, transaction size, white-listed addresses, recipient address(es), or text message (SMS) verification.
