THORChain is set to integrate privacy coin Monero into its mainnet within the next 1-2 months, following successful simulation tests. The project has now entered the code review and testnet phase. Concurrently, Bittensor is being developed to launch alongside Monero, while Zcash is targeted for integration by the end of April. The integration faces challenges related to the observability of privacy chains, which the team plans to address using a Frost-based multi-signature mechanism and specialized validator node structures.
