Tidecoin Development Roadmap

Tidecoin's roadmap has three phases. Phase 1 covers the live genesis-era design: Falcon-512 signatures and YespowerTIDE mining. Phase 2 covers the built-but-not-yet-activated feature set tied to AuxPoW activation: merged mining, additional signature schemes, OP_SHA512, and witness v1. Phase 3 covers longer-term ideas that should be treated as planning, not whitepaper-canonical release commitments.

What has Tidecoin already delivered?

Phase 1 covers the live genesis-era design: Falcon-512 signatures and YespowerTIDE mining.

// 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.

How activation works

Consensus gate
  1. 01All Phase 2 code is already implemented and tested.implemented + tested
  2. 02All features are gated behind nAuxpowStartHeight in consensus parameters.nAuxpowStartHeight
  3. 03Activation height will be set via a coordinated node software release.nAuxpowStartHeight = N
02

What goes live at once

Five simultaneous upgrades
  1. 01Scrypt merged mining — transition from standalone YespowerTIDE to Litecoin-secured merged mining; substantial increase in 51% attack cost via Litecoin hashrate leverage.
  2. 02Multi-scheme signatures — Falcon-1024 and ML-DSA-44/65/87 become spendable on mainnet.
  3. 03Witness v1 512-bit — 64-byte SHA-512 script hashing for 256-bit post-quantum security.
  4. 04OP_SHA512 opcode — SHA-512 in Script enables post-quantum hash operations in contracts.
  5. 05Strict PQ validation — legacy Falcon format rejected, tighter PQClean bound checks.
03

How to verify today

Testnet proof
  1. 01Mainnet is currently set to AUXPOW_DISABLED.testnet: height ≥ 1000
  2. 02Testnet is active at block 1000.mainnet: AUXPOW_DISABLED
  3. 03Activation height will be set via a coordinated node software release.consensus.h

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

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.

Roadmap FAQ

All FAQ

Is Phase 2 code already written?

Yes. All AuxPoW, multi-scheme, witness v1, OP_SHA512, and strict PQ validation code is fully implemented, compiled, and tested with unit tests and functional tests. Phase 2 is purely a consensus activation — setting a block height at which the features go live on mainnet.

When will AuxPoW activate?

The activation height will be set through a coordinated node software release with the mining community. All features are already testable on testnet (active at block 1000).

Will I need to update my wallet for Phase 2?

You will need to update to the latest node software release that includes the activation height. Existing keys and addresses will continue to work — no wallet migration is required.
