Bitcoin Escrow; The leading role in implementing the Bitcoin 2.0 technology solution today belongs to CryptoCorp. It was created by Ryan singer, who co-founded Tradehill.

The company’s offer is based on the fact that a significant number of people have been trying to implement and promote multi-signature transaction wallets for a whole year. Their work is extremely simple.

If the bitcoin address has one private key, then this option has three of them. To save one of them, conditions are used without observing top-secret measures, that is, similar to those used in a traditional Bitcoin wallet. To save the second key, it is best to use a safe or no less reliable place, and the third one is located on the server.

When a user needs to spend some part of their funds, the wallet will perform a transaction that they will sign in local mode.

After that, it is sent to the server. In the case of the simplest implementation, the server is required to enter the code received on the smartphone using an application called Google Authenticator.

It is required in order to overcome the threshold of the second check, as well as for the server to receive confirmation that the attempt to send money is being made by their owner. If the verification results are satisfactory, the transaction will be signed and forwarded to the network, confirmed by two signatures.

What does the CryptoCorp server do? It takes a basic idea to which two upgrades are applied.

First, we introduce a technology that has been assigned the name of a wallet that has a “hierarchical deterministic multi-signature” (HDM). Simply put, 3 secret keys are replaced with three predefined wallets. The latter are sources that have the potential to issue an unlimited number of private keys.

To produce a null address from the HDM wallet, the null public key from the source under the first number is combined with the analogs generated by the second and third.

Thanks to this, CryptoCorp wallets can have more than one address, and this raises the level of secrecy, just like in a Bitcoin wallet.
