Dash Platform Sprint 88 Review – Summary

Hey there! Here's DCG's 88th Sprint Review. Slowly but surely, we're coming closer to the platform release :)

Enjoy watching it. Or reading the takeaways down below.

TenderDash

Goal: Same block execution

Why we need this

• Better UX. Increase data insertion time (H instead of H+2)
• Reduce network load. There is no need to produce extra blocks to provide signature on proofs
• Reduce node IO. in case of next-block, RocksDB snapshots need to be created every block to provide signed state (H-2)

What we planned

• Implement same-block execution in progress
• Update vote-extension spec part for ABCI++ in review / on hold
• Validator key verification in review / on hold

What’s Next

• Implementation: same-block execution (multiple sprints)
• Backport remaining code from Tendermint master
• Important notes:
• Tendermint v0.35/v0.36 discontinued due to unstable network (p2p) layer
• test and stabilize on Tenderdash side

GroveDB

Goal: Worst Case Costs and GroveDB Replication

What we planned

• GroveDB Replication done
• Worst case costs in progress

What’s Next

• Efficient references
• Continuation on Worst Case Costs

SDK

Goal: Rework chain synchronization process (SPV) SDK repository documentation update

What we planned

• Block Headers Synchronization with 1 stream done
• POC of chain synchronization with storage done
• Unit tests 15%
• Integration tests 20%

What’s Next

• Support for multiple parallel block headers streams
• Consensus rules fine tuning for different networks
• Intermediate QA for the block headers synchronization
• Integration and unit tests

Protocol

Goal: Release v0.23 for testnet

What we planned

• Release and deploy v0.23 to devnet done
• Fix fee distribution bugs in progress
• Withdrawal transitions in progress

• Platform test suite browsers tests fail with NoAvailableAddressesError in CI in progress

• Dashify rust dashcore lib (addresses - magic numbers…) in review

Implement special transactions in rust dashcore lib

• Provider transactions (registration, service, registrar, revocation) in review
• Coinbase transaction in review
• Asset Lock in review
• Credit Withdrawal in review

What’s Next

• Continue on fee system
• Release Platform v0.23
• Continue work on withdrawals
• BLS Rust Bindings
• Special transaction BLS payload signing
• HTTPS for DAPI

Rust port update

The plan

• Integrate RS-Drive with DPP done
• Bring all changes from v23 into the Rust DPP port - in progress 3/17 - 2 finished and in review, 1 being worked on
• Make previous JS DPP tests work with Rust DPP binding
• Integrate Rust DPP into SDK, Drive, DAPI and test suite
