Tidecoin Development Roadmap

Three phases: Phase 1 is complete (Falcon-512, PQHD, ML-KEM live). Phase 2 is built and tested (AuxPoW merged mining, multi-scheme). Phase 3 covers long-term — hardware wallets, cross-chain bridges.

What has Tidecoin already delivered?

Phase 1 complete. Falcon-512 signatures, PQHD wallet, ML-KEM-512 transport, and the full Bitcoin Core v30 rebase live on mainnet.

5+ years of continuous operation. No publicly disclosed security incidents. No consensus failures. No hard forks.

// phase 2 · auxpow activation

What does the AuxPoW activation unlock?

All Phase 2 code is already implemented and tested. Phase 2 is a single consensus-height activation that simultaneously enables five features.

01

How activation works

Consensus gate
  1. 01All five upgrades are already merged, compiled, and covered by unit and functional tests on testnet.tests: unit + functional
  2. 02Mainnet behavior is gated behind a single consensus flag — no soft fork signalling, no miner voting.no soft-fork signalling
  3. 03A coordinated node release sets nAuxpowStartHeight; once the chain passes that block, five features flip on atomically.nAuxpowStartHeight = N
02

What goes live at once

Five simultaneous upgrades
  1. 01Scrypt merged mining — Litecoin-compatible AuxPoW, 100–1,000x increase in 51% attack cost.CONSENSUS_AUXPOW
  2. 02Multi-scheme signatures — Falcon-1024 and ML-DSA-44/65/87 become spendable on mainnet.CONSENSUS_MULTISCHEME
  3. 03Witness v1 512-bit — 64-byte SHA-512 script hashing for 256-bit post-quantum security.CONSENSUS_WITNESS_V1
  4. 04OP_SHA512 opcode — SHA-512 in Script enables post-quantum hash operations in contracts.CONSENSUS_OP_SHA512
  5. 05Strict PQ validation — legacy Falcon format rejected, tighter PQClean bound checks.CONSENSUS_STRICT_PQ
03

How to verify today

Testnet proof
  1. 01Testnet activates at block 1000 — every feature is already exercisable end-to-end.testnet: height ≥ 1000
  2. 02Mainnet reports AUXPOW_DISABLED until the activation height is reached.mainnet: AUXPOW_DISABLED
  3. 03Node operators can audit the gate by reading consensus.h and GetAuxpowStartHeight().consensus.h

All features gated behind nAuxpowStartHeight. Currently AUXPOW_DISABLED on mainnet, active at block 1000 on testnet.

// phase 3 · long-term

What is planned for Tidecoin's future?

Research and engineering tracks beyond Phase 2. Not consensus-critical — layered on top of the post-quantum base.
