Bitcoin Escrow Services

The bitcoin escrow service acts as a neutral third party between buyer and seller when doing business online. An escrow service is specially needed when making payments, buying things online, doing bitcoin exchanges on forums and similar. Since bitcoin transactions are irreversible many use escrow services.

An escrow service provides safer transactions by holding buyer’s coins in escrow which are released after both parties are satisfied. Some services also offer dispute resolution/mediation within escrow service. An escrow service protects seller and buyer.

Bitcoin Multisig feature

Multisig (short for multi-signature) bitcoin addresses have many interesting uses, and are not as complicated or difficult to use as it may seem at first. The basic idea is that more than one person must sign a transaction for it to be valid. Bitcoin has built-in feature that gives you an opportunity to choose as many signers as you like, and then choose how many signatures in total must be provided for a valid transaction.

For example, you can have two people who must both provide their signature (2 of 2) to validate the transaction, or you can set it up to require any 2 out of 3 possible signatures, or anything else which suits your needs. You can use multi-sig addresses to create a kind of joint account, which requires you and your partners to sign off on any withdrawals, or maybe requires a few company’s bosses to approve expenditures. You can also use them for savings wallets which require multiple signatures to increase security.

How To Use Bitcoin Multisig for Escrow

Probably the most common use of multisig is bitcoin multi-sig escrow. Multi-sig escrow provides consumer protection without the need to trust some escrow service (such as one described below) to hold coins on your behalf. Instead an address is created that requires 2 of 3 signatures from the buyer, seller, and a third person who provides arbitration in case there is a dispute. This address holds the payment until a product or service has been delivered, and can then be used to either make payment to the seller or refund the buyer.

Bitcoin Wallets That Support Multisig

The first escrow option is to setup a rule of minimum of 2 parties to sign on a multisig wallet of 2 keys. That means once a deposit has been made, both parties need to agree in order to move the funds. A second option is a minimum of 2 parties to sign out of a 3 key wallet (the seller, the buyer, an arbitrator). If there is a dispute, the arbitrator can sign with the buyer or with the seller, but cannot run away with funds.
