2 years ago, QRL mainnet was released on 26 Jun 2018, and has operated a fully post-quantum secure blockchain network not only without incident such as lost funds or a network hiccup, but also with the same capacity of the bitcoin network. It can, and has been done.
This stability is thanks to mainnet not only running one and a half years of testnet, right back to the seminal github commit on 16 Oct 2016 from Peter Waterland (surg0r), but also to our two audits from red4sec and x41 D-sec before the final release.
Relative to the date of this blog, this brings QRL, as a codebase, and the corresponding whitepaper release, to three-and-a-half years of age.
We’ve delivered on 13 different core features and 6 ecosystem features from a total of 8542 total contributions between 49 contributors over 29 repositories.
Core Quantum secure blockchain using XMSS with a 100% pq-secure address space GUI wallet for Mac, Windows, and Linux Full block explorer functionality Quantum Resistant Tokens (QRT’s) Notarisation Multiple external audits red4sec and x41 D-sec Extensible address format Multi-platform QRL node release Multisignature transactions Integration of Cryptonight v7, then RandomX PoW algorithms Backwards compatible state upgrades Ephemeral Messaging System (EMS) Stub and Tooling Ecosystem Keybase Integration Multiple API’s Hardware wallet support with Ledger Nano S/X Mobile wallets for iOS and Android Offline wallet generator Docker QRL Node Support Special thanks While the core team is a big part of it, so were a lot of QRL contributors.
