#Redspot

Help @shamb0 to complete the review of Redspot v0.3.

#Ask!

Framework:

Designed and implemented the StorableMap class, and implemented self-enumerable Map storage.

  • Exported the value of the entry Key in MetaData.json.
  • The format of the data stored on the chain is: key -> (value: next->key), so you can access the value stored under any key in O(1), or access to any value in O(n) iteratively.

Compiler:

  • Compiled all extension codes and migrated all to Ask! , Completely separated from ASC.
  • The inheritance and deployment of the reference file has been completed, and the problem of contract code must be in the same file is solved.

#Europa

  • The 0.3 proposal has been written and waiting to be submitted after Redspot’s vote is passed.
  • According to the proposal to design the development plan of version 0.3.

#Patract-Archive

Patract-Archive is a redesigned chain Archive project referred to Substrate-Archive. Its purpose is consistent with Substrate-Archive, and it is used to export chain state and block data. But Patract-Archive is more stable, extensible, supports multiple producer-consumer models, and is decoupled from the node environment. It is the basic component of Patract’s many data-related businesses (such as PatraScan, Elara, etc.).

The preliminary design of Patract-Archive has been completed within last week and this week, and we have a basic realization of the 0.1 framework, deleted the public components. We are about to be used in the testnet environment as version 0.1 within the next week.
