CasperLabs Update 19th May: Inclusion Bonds — Making ‘free gas’ work for Validators and Delegators

Update summary

This week at CasperLabs, the team started a new release cycle for Node 0.20, during the previous Testnet release, we introduced the notion of Omega blocks, this enables non-leader nodes to be able to propose blocks which would later be finalized by the leader Node at the end of a given round. Omega blocks would increase throughput on the network by enabling faster block proposal time. We’ll be making a more detailed blog post on Omega blocks.

Also, we’re enabling support for multi-cryptographic algorithms. This feature would capacitate CasperLabs blockchain to support Ethereum account keys, secure enclave for hardware wallets as well as ED25519 encryption.

Onur Solmaz gives a presentation on “Inclusion Bonds: Making ‘free gas’ work for Validators and Delegators”.

Engineering

  • The team has started a new release cycle and entered into the first of the four weekly sprints (Sprint 2.1).
  • The team has released Node 0.19 on GitHub and it’s currently undergoing stress testing with the Test and SRE team.
  • For the next four weeks, the team is going to be working on upgrading the Testnet with contract headers as well as multiple key support.
  • We’re creating a unified storage model on the Rust portion of the Node.
  • Enhancing the Key-gen tool to support account hashes and update GraphQL Schema to support multi-cryptographic algorithms.

Testnet

  • We observed that the Testnet was not stable with 18.1. We had to bounce the network and restart again with all validators on CasperLabs Node 0.18.2 (2f2273e1486985181123ddcd9501dc3e02d73e38).
  • Testnet was restarted on 2020–05–13 at 19:00hrs UTC.
  • During this round, we introduce the notion of Omega blocks. An Omega block functions as both a witness and a state update. This feature enables the node to propose a transaction by creating an Omega block instead of Omega ballot when the deploy buffer contains deploys to process.
  • We are observing issues with 4 nodes and also the multiple era bonding issues. We are piloting fixes with 2 validators.

Current status

  • We are testing Node 0.19 with deploy gossiping on our Long-running test framework.
  • Moving from accounts identified by public key bytes to an account hash to support a multi-cryptographic signature algorithm. This would enable us to use multiple encryption schemes that support Ethereum accounts, secure enclave as well as ED25519 encryption in our notion of accounts.
  • As a result of the multi-cryptographic signature algorithm, we would be updating the python client, CLarity explorer, smart-contracts.
  • Building CasperLabs JS stack. This would enable users to be able to send deploys, transactions, and call smart contracts directly from their browser interface.
