Changelog

Methodology

0.7.0

0.6.0

  • Upgrade all libp2p version identifiers
  • Move all eligible-defining NFTs to oeth:0x66747bdc903d17c586fa09ee5d6b54cc85bbea45
  • Deprecate RPC_HTTP_HOST
  • Fix bugs with indexing logs. attestate/crawler order function was ordering logs based on blockIndex and transactionIndex, but logIndex was necessary too.
    • We've essentially created two new indexing strategies ("list-delegations-2", and "op-call-block-logs").
  • store.posts now tolerates finding "in-eligible" messages
  • Added docs that explain how Kiwi News Protocol's set reconciliation works
  • Use a DFS to traverse the tree for posts (thank you to @freeatnet!)

0.5.0

  • Deactivate revocations temporarily until we're properly implementing them in the set reconciliation algorithm. Details.
  • Upgrade all protocol major versions.

0.4.0

  • Require new environment variable OPTIMISM_RPC_HTTP_HOST
  • Website: Minor stylistic changes
  • Protocol:
    • All semantic version identifiers have been upgraded as a major version to avoid name collisions with nodes running older versions of this software.
  • API
    • POST /api/v1/list endpoint now adds two new properties to a message identity and signer.
    • POST /api/v1/messages now accepts messages signed from a delegate address.
  • Docs
    • Document difference in ports between API and frontend

0.3.0

  • Environment Variables
    • Rename TIMESTAMP_TOLERANCE_SECS to MAX_TIMESTAMP_DELTA_SECS
    • Separate HTTP_PORT (for website) and API_PORT (for node API)
    • Remove all TODAYS_EDITOR_... variables
  • Add Sphinx docs
  • Many changes to the frontend (won't list details)
  • Separated website frontend from node API frontend. They now run on differnet ports.
  • The allowlist registry now guarantees returning a set of unique Ethereum addresses.
  • The level's remote comparisons are now validated at the receiving node with a JSON schema.
  • For the frontend (mainly), ecrecover can now cache recovering signatures.
  • Logging of errors in the reconciliation algorithm has been improved.
  • The "leaves" function can now be called with a "startDatetime" parameter to speed up database queries.
  • Database migration
    • This release contains an incompatible database migration from earlier releases! If you actually need to migrate from 0.2.0 to 0.3.0, contact @timdaub!
    • LMDB now uses "ordered-binary" key encoding to enable range based key queries.
    • Our message hashing and identity generation was broken and so messages weren't canonically hashed. This had to be addressed in a database migration and by fixing the canonicalization. Again, if you really must migrate your data, make sure to contact us beforehand!
    • We enabled "useNodePruning" in ethereumjs/trie (this gets rid of deleted nodes).
  • Protocols
    • Upgrade "leaves" protocol to v3.0.0
    • Improve PMT traversal algorithm that had a bug when branching factor was too big (vendored in WalkController from ethereumjs/trie).
    • Improved atomic committments of data entry within set reconciliation. Made both metadb and trie transactional.

0.2.0

  • We discovered a critical issue in the v0.1.0 code base that lead to digests of messages in the ordering algorithm to be non-canonical [1] (thanks @freeatnet).
  • We're fixing this using npm:canonicalize that implements RFC8785 for canonical JSON.
  • Since we already had nodes in the network with existing data we shipped our first migration too. It checks for the digest algorithm, and applies a migration accordingly. We strongly recommend doing a backup of the DATA_DIR before applying the v0.2.0 update.
  • To avoid synchronizations between v0.1.0 nodes and v0.2.0 nodes, we upgraded all protocol and pubsub identifiers and versions too to avoid corrupting data bases.
