chore: update minimum chain work, tx stats, checkpoints, seeds for v23.1

[kwvg]

Additional Information

• SECURITY.md remains unchanged for minor releases.

• The blocks used as checkpoints are

  • For mainnet, block 2361500 (0x000000000000000718ed026ebd644a8b70b42d4cbd7b25304c066c9bf15f85b7, Insight)
  • For testnet, block 1239600 (0x000000a98084beaf77ed26a905a7d59979009e23367a55b5d634962d7d65a1f9, Insight)

• m_assumed_{blockchain,chain_state}_size calculations

  • Mainnet synced till block 2421861, Dash Core v23.0.2 (release)

    $ du --exclude ~/.dashcore/testnet3 --max-depth=0 -h ~/.dashcore
    52G     /home/debian/.dashcore
    $ python3 -c "print(round(52*1.1))" # 10% leeway
    57
    $ du --max-depth=0 -h ~/.dashcore/chainstate
    241M    /home/debian/.dashcore/chainstate

    As m_assumed_chain_state_size is still <1GB, we don't update it

  • Testnet synced till block 1420138, Dash Core v23.0.2 (release)

    $ du --max-depth=0 -h ~/.dashcore/testnet3
    8.9G     /home/debian/.dashcore/testnet3
    $ python3 -c "print(round(8.9*1.1))" # 10% leeway
    10
    $ du --max-depth=0 -h ~/.dashcore/testnet3/chainstate
    76M    /home/debian/.dashcore/chainstate

    m_assumed_blockchain_size remains unchanged for testnet.

• Mainnet seeds generated using protx list valid 1 2421861, testnet seeds generated using protx list valid 1 1420138, commenting out deduplication (source) and raising the MAX_SEEDS_PER_ASN to 10 (source)

Breaking Changes

None expected.

Walkthrough

This pull request updates seed node lists and chain parameters across multiple configuration files. Changes include replacement of onion and IPv4 seed node entries in contrib/seeds files, updates to consensus checkpoints in src/chainparams.cpp (nMinimumChainWork, defaultAssumeValid, chainTxData with new height references), and corresponding updates to the serialized seed arrays in src/chainparamsseeds.h. No functional logic or control flow is modified; all changes are data-only, affecting node discovery configuration and chain progress validation points.
