This release brings upon a few changes, primarily around refactoring interchain network management. Keys for interchain networks such as ethereum or bitcoin are no longer provided upfront before dragonchain creation, but can be provided by the user via various new endpoints (supported with the lastest versions of the SDKs). This also allows users to provide their own private keys for specific ethereum/bitcoin/etc addresses if desired.

Additionally, this release comes with various fixes for the deployment process, which are updated in the docs.

Changelog

  • Feature:
    • Switch to using files for reading secrets for dynamic secret update support
    • Use new schema for NETWORK (for L5 registration and blocks). Will now look like "{blockchain} {extra_data}"
      i.e. "bitcoin testnet3" or "ethereum network_id 2" rather than a pre-set list of enums as before.
      (This allows for things such as custom/private ethereum networks, etc)
    • Add support for creating/saving various interchain networks, including custom interchain nodes, keys, etc
      • Note this also means that a chain can have multiple addresses for the same type of network now (i.e. many ETH addresses)
    • Add routes for refactored interchain support:
      • POST /v1/interchains/bitcoin Create a bitcoin network for the dragonchain to use
      • POST /v1/interchains/ethereum Create an ethereum network for the dragonchain to use
      • PATCH /v1/interchains/bitcoin/<id> Update an already existing bitcoin network of dragonchain
      • PATCH /v1/interchains/ethereum/<id> Update an already existing ethereum network of dragonchain
      • POST /v1/interchains/bitcoin/<id>/transaction Create a bitcoin transaction using one of the chain's networks
      • POST /v1/interchains/ethereum/<id>/transaction Create an ethereum transaction using one of the chain's networks
      • GET /v1/interchains/<blockchain> Get a list of all registered Dragonchain interchains
      • GET /v1/interchains/<blockchain>/<id> Get a particular interchain network from the chain
      • DELETE /v1/interchains/<blockchain>/<id> Delete a particular interchain network from the chain
      • POST /v1/interchains/default (L5 only) Set a default network for level 5 chains to use
      • GET /v1/interchains/default (L5 only) Get the default network set on a level 5 chain
    • Move the following routes legacy support only (they will work for chains upgraded from an old version for backwards compatibility, but will 404 on new chains):
      • GET /public-blockchain-address
      • GET /v1/public-blockchain-address
      • POST /public-blockchain-transaction
      • POST /v1/public-blockchain-transaction
    • Reduced initial delay checks for the webserver so kubernetes will mark the webserver as ready quicker
    • Add direct TLS support for the Dragonchain webserver (for NodePort deployed services)
  • Bug:
    • Fixed some bugs with the helm chart which caused the incorrect dockerhub image to be pulled
  • Documentation:
    • Add docs/update helm chart and values for added TLS support
    • Fixed/elaborated on some of the process for connecting to Dragon Net, including exposing a chain to the internet
    • Add an export which allows hmac key generation to work correctly on MacOS
    • Update Helm chart/values to remove unnecessarily exposed settings
    • Add creation of the dragonchain namespace before creating a secret on deployment
    • Update Golang SDK URL
    • Various spelling fixes
  • Development:
    • Refactored interchain support for easier future integration with further interchains
  • Packaging:
    • Updated boto3, kubernetes, redis, and web3 dependencies
    • Removed unnecessary dependencies, and added speedup extras for aiohttp
    • Update fwatchdog to 0.16.0 for OpenFaaS smart contracts
