Network Evolution & KMD Burn: Enhancing KMD's Role in Komodo's DeFi Framework

Introducing pivotal network enhancements to pave the way for an evolved DEX P2P network, Komodo DeFi Framework 2.0.0-beta marks a strategic step forward. This release not only streamlines network performance but also introduces a deflationary aspect to KMD, underscoring its utility and value in Komodo Platform's expanding ecosystem.

Release Notes

Features:

  • KMD Burn:
    • Burning 25% of the taker fee when paid in KMD was implemented by @onur-ozkan #2006
  • Swap watcher nodes (only for UTXO/UTXO swaps):
    • For UTXO/UTXO swaps, watcher nodes will either complete the swap for taker or refund the taker payment if the taker goes offline after sending their payment. This was implemented by @caglaryucekaya in #1457 #1496 #1523 #1552
    • Using watcher nodes for swaps were enabled by default for UTXO/UTXO swaps by @caglaryucekaya. All nodes doing a swap will broadcast a watcher message after the taker payment is sent if both coins swapped are supported by watchers (currently only UTXO) #1859

Enhancements:

  • Network Enhancements:
    • P2P layer was upgraded to use the latest stable libp2p version by @onur-ozkan #1878
    • 7777 network was deprecated by @onur-ozkan #2020.
    • Seednodes for netid 8762 were updated by @smk762 #2024
    • libp2p-yamux was updated by @onur-ozkan to use yamux v0.13 (new version) by default and to fall back to yamux v0.12 (old version) when setting any configuration options #2030
    • The backpressure buffer cap was increased from 25 to 256 by @onur-ozkan #2030
    • New protocol version (Version2) was added by @onur-ozkan to be used for peer exchange and request-response behaviours in #2030
    • Network information is now written to stdout so users can find mm2 ports easily @onur-ozkan #2034
  • NFT feature was released in v1.0.6-beta, this release adds significant enhancements to this feature:
    • exclude_spam and exclude_phishing params were added for get_nft_list and get_nft_transfers RPCs by @laruh #1959
    • Spam transfers with empty meta was fixed by @laruh to no longer update #1989
  • version method was added to PUBLIC_METHODS that require no login by @smk762 #2001
  • An additional PRICE_ENDPOINTS url which is a cached copy of https://prices.komodian.info/api/v2/tickers and is updated every minute was added by @smk762 #2032

Bug Fixes:

  • ARRR/Pirate:
    • ARRR infrastructure for lightwallet servers uses a fork of lightwalletd, the grpc service was renamed by @smk762 from cash.z.wallet.sdk.rpc to pirate.wallet.sdk.rpc to use the lightwalletd fork #1963
    • Previous blocks/wallet sync was fixed by @borngraced to be resumed if sync_params are not provided after restart #1967
  • EVM web3 requests timeout was reduced to 20s by @shamardy #1973
  • Fixed 0.0001 min threshold for TakerFee was removed by @shamardy #1971
  • The minimum trading volume for evm and tendermint was changed to be the smallest possible amount of the coin by @shamardy #1971
  • Minimum trading price was reduced by @shamardy to be any value above 0 #1971
  • Cryptocondition script type was added to utxo transactions by @shamardy #1991
  • On response error the next web3 node is now tried @shamardy #1998
  • Watchtower taker-side restart bug was fixed by @caglaryucekaya #1908
  • rpcport value can now accept a string @shamardy #2026

NB - Backwards compatibility breaking changes

  • 7777 Network deprecation and the upgrade to a new p2p layer breaks compatibility with previous versions of Komodo DeFi Framework. Connections between nodes/clients running an older version of Komodo DeFi Framework and nodes/clients running this version will not be possible. To avoid this, all nodes/clients must be upgraded to the latest version of Komodo DeFi Framework.
  • Because of KMD burn of a part of the taker fee, the taker fee outputs for any coin/KMD swap are changed and makers running older versions will not be able to validate the taker fee, this will cause the swap to fail. This case will never happen anyway because older versions will not be able to connect to this latest version due to the network upgrade.
  • Because of the removal of the fixed 0.0001 min threshold for TakerFee, taker fee validation will also fail for these cases. Again, this case will never happen as the previous case.
