v10.4.0

Release Notes - Counterparty Core v10.4.0 (2024-09-18)

This is a major release with numerous protocol upgrades that will dramatically increase the functionality of the Counterparty protocol as well as resolve some long-standing security issues, in addition to a number of bugfixes and quality-of-life improvements.

Upgrading

If you run a Counterparty node, be sure to upgrade your node as soon as possible. Your node must be upgraded by block 866,000, which should be mined around October 16th, 2024, approximately four weeks from today.

The upgrade procedure should be straightforward: the API remains backwards-compatible, and the node will not have to perform a reparse. There are, however, two notable changes in this release that will require attention:

1. It will no longer be possible to create a dispenser from an address that you don’t control. You will have to create the dispenser from the source address of the transaction, like all other Counterparty transactions.

2. It will no longer be possible to trigger dispensers using vanilla Bitcoin wallets. The create_send API call has been modified so that it will automatically turn any BTC send to a dispenser into a create_dispense transaction.

v10.3.0

Release Notes - Counterparty Core v10.3.0 (2024-07-12)

This version most notably introduces a major performance optimization for node API access: an additional SQLite3 database has been added which tracks the current state of all Counterparty objects (in addition to the primary database that is purely log-structured). Other major changes for this version include the removal of the kickstart functionality, which is possible now that start is performant, and numerous tweaks and improvements to the v2 API.

Upgrading

This update requires an automatic full reparse of the Counterparty transactions to populate the new database file. This process may take a number of hours to complete.

ChangeLog

Bugfixes

• Fix verbose logging of order matches

• Parse transactions vouts with Rust
• Optimize get_matching_orders() with consolidated cache

API

• Introduce the following new routes:
  • /v2/transactions/<tx_hash>/sends

v10.2.0

Release Notes - Counterparty Core v10.2.0 (2024-06-11)

This is a large release that includes significant refactoring and redesigns of critical node components, including the CLI and logging subsystems, mempool processing, and API database connection management. It also includes numerous updates and extensions to the v2 API, plus new ZeroMQ support. Of course, a large number of bugs have been resolved as well.

Upgrading

The counterparty-server process now uses ZeroMQ to communicate with Bitcoin Core, in addition to the traditional RPC API. You must configure Bitcoin Core with:

[main]
zmqpubrawtx=tcp://0.0.0.0:9332
zmqpubhashtx=tcp://0.0.0.0:9332
zmqpubsequence=tcp://0.0.0.0:9332
zmqpubrawblock=tcp://0.0.0.0:9333
[test]
zmqpubrawtx=tcp://0.0.0.0:19332
zmqpubhashtx=tcp://0.0.0.0:19332
zmqpubsequence=tcp://0.0.0.0:19332
zmqpubrawblock=tcp://0.0.0.0:19333

Note: This update requires a reparse from Block 819250, which will proceed automatically upon initialization.

ChangeLog

Bugfixes

• Fix circular imports
• Return 404 errors for undefined API routes

• Fix the execution interval of the APIStatusPoller thread
• Add Access-Control-Allow-Headers = * header to API v2 for CORS

Codebase

• Refactor mempool management and block tracking—catching up is now done via RPC, and tracking via ZeroMQ
• Introduce a new Rust module to fetch blocks from Bitcoin Core over RPC. Calls are now massively parallelized and buffered; block fetching no longer slows down block parsing
• Refactor the backend module; separate calls to Bitcoin Core and AddrIndexRs into two different modules
• Add the indexed tx_hash field to the messages table
• Update rowtracer so that apsw returns a boolean instead of an integer for BOOL type fields
• Delete the defunct implementation of rock-paper-scissors; introduce a replay_events() function to reconstruct the database from a hard-coded list of historical events
• Enable parsing blocks while Bitcoin Core is still catching up
• Optimize get_pending_dispensers() by adding the last_status_tx_source and close_block_index fields to the dispensers table; optimize is_dispensable() by caching a list of all dispenser addresses
• Add the transaction_count field to the blocks table
• Add the following new database indexes:
  • credits.calling_function
  • debits.action
  • transactions.source
  • credit.quantity
  • debit.quantity
  • balance.quantity
  • dispenser.give_quantity
  • order.get_quantity
  • order.give_quantity
  • dispense.dispense_quantity
• Add the new EVENT log level
• Disable the automatic SQLite ‘quick check’ for when the database has not been closed correctly. Display an error message when exiting and at the next restart.
• Add retries to get_oldest_tx() on a Addrindexrs timeout

  • /v2/assets/<asset>/dispenses
  • /v2/addresses/<address>/issuances
  • /v2/addresses/<address>/assets

• Make the asset, assets, give_asset, and get_asset parameters case-insensitive
• Add the named=true|false parameter to /v2/assets to returning only named / numeric assets
• Publish events on the ZeroMQ Pub/Sub channel
• Implement database connection pooling for both API v1 and v2
• Enrich results containing block_index with block_time when verbose=true
• Add an action filter for the */credits and */debits routes
• Add an event_name filter for the */events routes
• Specify issuer=None within XCP and BTC asset information
• Exclude zero balances in the results of /v2/addresses/<address>/balances and zero quantities in the results of */credits and */debits
• Add BTC sent to the DISPENSE event
• Accept trailing slashes in routes
• Include first_issuance_block_index and last_issuance_block_index in asset information
• Add normalized quantities for the following fields:
  • fee_paid
