Proton Mainnet launched in May of 2020. Our core 21 Block producers started validating blocks immediately, this can all be tracked on our block explorer Bloks.io.
iOS and Android Open Source Wallet SDKs were released. This is the core tech used in the Proton Reference wallet, and was made available for all apps to embed Proton functionality.
In September 2020, we released the open source Web SDK, allowing users to authenticate and accept payments using Proton Signing Request (PSR).
We released an ERC-20 Wrapping and Unwrapping tool. This tool allows users to move between ERC-20 coins to Proton coins and back.
We have implemented a lite version of on-chain KYC already with Trulioo. Further KYC vendor integration is expected in Q4. With on chain KYC, individuals and companies can have the "verfied checkmark" on chain, and across apps.
In Dec 2020, we implemented a tiered resource lending model, where for a fixed monthly price developers can secure CPU, NET, and RAM resources needed to run their apps.
Proton Chain was developed with the intent of recording payment pending transactions of fiat as well as crypto transactions. As fiat bank accounts are moved into Proton wallet we will demonstrate the first examples of that.
As stated in the original whitepaper, the ultimate goal of Proton is to process payment pending transactions for fiat on chain. In order to effectively roll this out, we need to integrate the Metal banking and Proton Wallet functionality. This is an ongoing process that our team is dedicated to.
We plan to offer staking rewards on all coins in time, with these coins being safely lent out at high rates of interest (subject to approval).
Proton already does support the Simple Asset protocol. We are working on further NFT support and examples.
