  • Researched and confirmed the browser implementation of the Redspot command program, which is under development.



  • Continue to develop cross-contract calls through interface calls, and code generation is basically completed.
  • We are about to generate metadata.json in JSON.


  • The StorableMap.ts code is completed.
  • Part of the code of the Framework is located in the v0.2-me branch, and will be placed in the v0.2-dev branch after the test is passed.


  • Europa v0.2 Code Review is over, and report can be found at [Here]
  • Reorganized Europa’s Release version, changed the version number to v0.1, v0.2, etc., added Substrate-v2.0.0 and Substrate-v3.0.0–1 tags for Substrate’s dependent version.
  • Locating the problem of parsing failure in the Name Section of the compiled Wasm file due to the rust version upgrade. It is about to be fixed next week. Therefore, if you want to use Europa’s Wasm Backtrace function normally, you need to limit the tool chain for compiling the contract to nightly-2021–03–03.
  • Submitted a development proposal for Europa v0.3, which will increase the UI interface and cross-platform binary packaging and distribution functions. Please check Proposal link.


Version v0.1 (based on Rocksdb storage version)

  • Rebuilt the Actor model to make it decoupled and componentized
  • Debugged and fixed issues with v0.1 version
  • Added missing storage of the original Genesis block

Version v0.2 (based on the substrate source code)

  • Adapted Dev Genesis Json.
  • Completed block generation of Mock Runtime, and write DB and Kafka.


  • The new official website is online, the new interface system displays the user’s usage data more clearly than before.
  • Fixed the bug that the long-time subscribed link returns empty data.
  • Added a new Polkadot node and kusama provided more powerful concurrency capabilities.
  • Added support for Westend.
  • In this week, nodes cannot provide services, so users can only choose other Endpoints to provide services in Polkadot’s Apps wallet. In this process, Elara took over the main traffic and provided high-quality access, which proved the superiority of the system behind Elara (the back of Elara is not a simple node cluster, but uses Patract’s self-developed technology).


  • Completed the Substrate storage structure document.
  • Completed the Substrate UML diagram.
  • Completed the page display logic design of the Democracy and Staking modules.
