Learn QRL 2.0
Plain English guides to QRL 2.0: how post-quantum signatures and proof of stake work, and how to use wallets, staking, swaps, tokens, and smart contracts on the network. Written by the team that builds ZondScan and MyQRLWallet. Every guide runs on the public testnet, where coins have no monetary value, so you can follow along and experiment freely.
QRL 2.0 basics
The core ideas behind the chain: proof of stake consensus, post-quantum signatures, the units amounts are counted in, and how validity proofs could scale it.
What is QRL 2.0?
A plain English introduction to QRL 2.0: proof of stake consensus, EVM smart contracts, ML-DSA-87 signatures, and how the new chain relates to legacy QRL.
