What is FIO Protocol?
The FIO Protocol is bridging the gap between wallets (both exchange-based and self-sovereign) as well as crypto payment processing platforms providing an industry standard decentralized service layer of data, requests and confirmations that abstract away the complexities of the underlying blockchains. The FIO Protocol is not a wallet, not an exchange and not a crypto payment processor, rather, it enables them all to deliver a dramatically improved user experience. The FIO Protocol does not compete with other blockchains nor does it send value on or integrate with other blockchains but, rather, it enables them all to be more successful. Technically speaking, all other blockchains do not even know that the FIO Protocol exists.
FIO Addresses will act as the human readable “wallet names” and user identifiers on the network. In addition, FIO Addresses are the gateway to all other capabilities of the FIO Protocol. Registration of a FIO Address is done in a FIO enabled wallet or exchange where a FIO Private/Public Key pair is generated. The FIO Address and all actions on the FIO Chain are self-sovereign via the FIO Private Key. Without a FIO Address, users cannot access any of the other FIO protocol capabilities.
A FIO Request is a transaction in which a payee is requesting funds from payer using FIO Addresses. The payee first encrypts all sensitive metadata (e.g. currency, amount, public address of payee, memo, etc.) using Diffie-Hellman key method , which derives a shared secret from the payee private key and the payer public key and places the transaction on the FIO Chain. The payer polls the FIO Chain, decrypts the metadata inside their wallet and uses the information to pre-populate the send transaction, which is broadcasted to the native blockchain without involving the FIO Protocol.
In addition, the payer places a metadata about the native blockchain transaction (e.g. native blockchain transaction id, refund address, memo, hash of off-chain metadata, etc.) on the FIO Chain. Just like the request, the metadata would be encrypted using Diffie-Hellman key method.
If you are interested in integrating FIO Protocol into a wallet, check out our Wallet Integration Guide, and if you are ready to dive into code, our API spec will explain all the calls we provide. Alternatively, make it easy on yourself and take a look at some of our SDKs.
If you want to dive into the FIO Chain code and spin-up your own node or even become a block producer, check out the FIO Chain section for more information about building a node.
We have a Testnet up and running, check it out here.
