Contents in brief

Technical update

  • RNode 0.6.1 released.
  • Focusing on bugs and stability as the highest priority.
  • Node testing is progressively successful and Medha is on triage every Tuesday after node testing.
  • Sharding and economics for consensus are not ready. These will be part of RNode 0.7.
    • The team will be delivering features on the testnet all the way up to November.
    • Medha is working on proposing release criteria, and will work with the development team & Co-op board to settle on these criteria.

Rholang team

  • The registry is in implementation. It will support UUID and public keys only.
  • Planning on compressing the block data before sending it.
  • The block approval protocol for genesis block is in review.
  • Integration of the block store is in review. This is a large PR that depends on the genesis block approved PR.
  • Unbonding contract in review. It’s not going to be integrated in time for testnet but there will be a fast follow-on with it.
  • Error handling in Casper in review.

Storage team

  • Addressing issues in RSpace relating to thread management and performance.
  • Discovered an LMDB single writer limitation, so moving to a hybrid solution where the in-memory hotstore and LMDB are used.
  • Implemented an update frame size to support 108 MB block size by default. The size is also configurable via command flag on node startup.
  • Made some performance harness improvements.
  • There is a Grafana dashboard that can be used for testnet.
  • Building gRPC clients and API for client data retrieval.
  • Improving memory monitoring metric.


Abstract /Demo

  • Medha gives Grafana dashboard demo
  • Kayvan gives proof of concept audio demo
    • Proof of concept allows music to be stored on the blockchain and any device. Android, iOS, PlayStation etc. can subscribe.
    • It allows deployment of RChain code on tiny cheap devices such as a Raspberry Pi.
    • By installing RChain on a small Raspberry Pi, we can store IoT data onsite to the blockchain.


Pithia’s update

  • Pithia’s agreement with the co-op has been signed and updated.
  • 9 of 18 companies in the pipeline are under due diligence.
  • Three pitches took place in the Pithia offices in Seattle:
    • ERP for mining. This company is building software that manages the different aspects of mining: mining pools, asset management, and all things related to how operations are run, measured, and managed.
    • IoT security for blockchain. This company has developed a blockchain implementation that allows for securing the chipsets that manage IoT devices. They’ve already established partnerships with key chip manufacturers.
    • DEX – This distributed exchange is already live and building operations to allow wallet-to-wallet swaps of curated tokens on a blockchain.
  • Lucidity and lifeID to present at RCon3
  • They’ve announced office hours with CoMotion, a tech transfer organization at the University of Washington.
    • The team will be attending the Blockchain Seattle event.
    • Lawrence will be interviewing Washington state senator Reuven Carlyle at the Blockchain Seattle event to discuss the role of government and public private partnerships.
    • Rholang educational course material for a local coding academy in Washington state is looking for teachers.
    • The team is in connection with a smart ticket company. They have built an ERC721 token for tickets to be sold just like Ticketmaster, StubHub.
    • Building a strong relationship with Amazon Web Services for the community.

Reflective Ventures update

  • CRM system is set to manage validator inquiry responsibly.
    • The team introduces Ned Robinson to the co-op. He will be assisting the solutions group to help signed companies technically deploy on the RChain platform.

Validators sale

  • The staking amount ranges from a minimum of $1500 to $1,000,000.

The Tranche discounts:

$1,500 – $250,000   15.26% off spot

$250,001 – $999,999   18.36% off spot

$1,000,000+   21.36% off spot

  • John West shows a competitive analysis of interest paid on stake by other PoS projects.

  • The team came up with a 15.26% token sale discount for a nominal yield of 12%. The idea is, instead of minting new tokens or taking inflationary actions, tokens are sold at an additional 15.6% discount, with the benefit of a 12% nominal yield.
  • The  total return for the lock up period (18 months) compared to other staking competitors shows that RChain is paying 18% – 20% which is highly competitive.
