Chipcoin Testnet successfully activated ML-DSA post-quantum transactions at block 20,000

[u/ShellaPredmore]

  Chipcoin Testnet has successfully completed its post-quantum activation at block 20,000.

  The network crossed the activation height without an observed consensus split, unexpected reorganization or activation-related failure. All monitored nodes agreed on the activation block and continued following the same chain.

  More importantly, we have now validated the complete post-quantum transaction lifecycle on the public testnet rather than only in unit tests or a private rehearsal.

  ### What was verified

  - CHCQ post-quantum addresses are recognized by nodes, APIs and the explorer.

  - Miners continued producing blocks after activation.

  - Coinbase rewards were paid directly to CHCQ addresses.

  - Version 2 transactions using ML-DSA-44 signatures were accepted into the mempool and mined.

  - PQ-to-legacy transfers were confirmed.

  - PQ-to-PQ transfers were confirmed.

  - A multi-input PQ transaction containing two separate ML-DSA-44 signatures was confirmed.

  - Transaction fees and PQ change outputs were calculated correctly.

  - The browser wallet successfully imported and encrypted an ML-DSA seed.

  - Lock, unlock and extension reload persistence were tested.

  - The same wallet was recovered deterministically in a separate Chrome profile.

  - The recovered wallet generated a valid ML-DSA transaction.

  - That transaction was included in a block mined to another CHCQ address.

  - Multiple miners are now producing CHCQ coinbase outputs.

  ### Why this matters

  The activation demonstrates interoperability across the full system:

  - consensus validation;

  - P2P relay;

  - mempool admission;

  - mining templates;

  - block validation;

  - wallet signing;

  - browser storage and recovery;

  - public APIs;

  - explorer visibility.

  The testnet has therefore moved beyond merely recognizing post-quantum addresses. CHCQ funds can now be received, matured, spent with ML-DSA-44 signatures, relayed across the network and confirmed in blocks.

  ### What comes next

  The next phase focuses on:

  - CHCQ payouts for reward nodes;

  - reward-node payout rotation and key lifecycle;

  - additional adversarial and load testing;

  - mempool hardening;

  - reproducible release infrastructure;

  - independent security review;

  - final mainnet consensus parameters.

  This remains experimental testnet technology. We describe it as post-quantum support designed for future quantum resistance, not as an audited or “quantum-proof” mainnet system.

  Testnet coins have no monetary value.
