Medha
- RChain Improvement Process (RCHIP Process) - Draft
- Release blocking bugs fixed. Node testing to verify fixes is planned after the hangout today. See #node-testing for call details.
- Once bugs are verified, we will re-launch test net on October 22nd. Relaunch described in Information for testnet launchers and validators.

Rholang team:
- Example package manager in Rholang provided to the community. Created for demo purposes by Mike.
- We have examples of how to use the registry in Github, under rholang/examples.
- Solution found for using " @(*contractName, "method") " The team will register all the contracts at public keys. Examples of this pattern will be provided for dApp developers.
- Porting of contracts is under way. Expect these will be done in the next week.
- Rholang API to supply deploy information to payment code in review.
Casper team
- Fixed issues around adding blocks to the local DAG. There was some inefficiency in the code base that was creating the problem.
- Moved to the inMemory block store for the time being. The new on disk block store comes next sprint. Look for increased memory utilization in the node.
- Non-deterministic bugs have gone into hiding for the moment. A lot of work has been done on the platform, so we will push forward with updating testnet.
- Suppressed the protocol handshake messages in the server console.
- Validation of the genesis block takes too long. This will be investigated by the RSpace team in a future sprint.
- Block Store is in implementation. PR for Latest messages store expected tomorrow.
Node team
- Fixes made in stream API, included in release.
- Working on compression implementation.
- Working on supporting dynamic IP addresses in the node.
- Writing up a proposal around serialization and de-serialization. Suspect that we may not be efficient in our use of protos.
Storage team
- Benchmarking scodec serializer against cryo serializer, working with Artur, who is working on something similar for the Interpreter.
  - Cryo is only slightly faster than protobufs. Less than 10%
- Almost no performance gain from the batch Trie Update/Merge strategy.
SRE team
- Working on enhancing integration tests to support testing for clique safety
- Work in progress to improve the integration test suite.
- Work in progress to improve debugging by implementing a process to obtain server logs from nodes.
- Support for the testing and release of RNode v0.7.
Incentivized testnet
- Work in progress to develop this program. Look for more information in Oct. and the start of the challenges around Dec.
Website - https://developer.rchain.coop
- Will include updates with the release of RNode v0.7
