Quantus Weekly: Dirac Testnet Release and Lattice Crypto Audit

This week the team released the Dirac testnet, finalizing the chain-wide update to the proof of work algorithm and lattice cryptography library, qp-rusty-crystals. This core library is now under external audit and includes constant-time signatures. The update is now integrated into the mobile wallet and libp2p.

IF YOU ARE A MINER YOU SHOULD UPDATE TO THE NEW DIRAC TESTNET
