Dash Platform Development Update - 2022 October 4

Hey there, fellow Dashers!
We continue providing updates on Dash Platform development.
Here's the freshest one.

TenderDash

Goals: Same block execution

Task

• Stabilization of same-block execution in progress

What’s Next

• Stabilization of same-block execution
• Investigate deadlocks in consensus

GroveDB

Goals: Fee continuation and Sum Trees
Tasks
Features

• Sum Trees in progress
• Merk Sum Trees done
• GroveDB Interface done
• Sum Tree propagation in progress
• Removal on Root Tree storage in progress

Trees explanation
Problem: We have a root tree storage that is incompatible with our fee model.

Cost of the Parent Tree:

• Key
• Value (32 bytes)
• Value Hash (32 bytes)

Cost of the Top Node of Sub Tree:

• Key
• Value
• Value Hash
• Root Storage Cost
• Key
• Path Hash

Solution: Use Parent Trees to store the root key of underlying Merks.

Cost Savings:

• Key - Key (Cancels out)
• Path Hash (32 Bytes)
• Parent Root Hash (32 Bytes)

Cost of the Parent Tree:

• Key
• Sub Root Key
• Value Hash becomes Subtree Root Hash (32 bytes)

Cost of the Top Node of Sub Tree:

• Key
• Value
• Value Hash Root Storage Cost Key Path Hash

What’s Next

• Continuation of removal of root tree storage
• Verifying all cost tests
• Worst case costs after changes

SDK

Goals: Rework chain synchronization process (SPV)

Tasks

• Unit tests 75%
• Integration tests 20%

What’s Next

• QA for refined transactions sync process
• Testing with platform on testnet

Protocol

Goals: v0.23 alpha release

Tasks
Alpha release of Dash Platform v0.23.0
Testnet upgrade to new architecture and OS will take about 2-3 days
Dashmate and SDK will be released as well

• Add withdrawal to withdrawal queues in RS Drive in progress
• Implement helper container which will renew certificate automatically in progress
• Multi transaction support in Drive in progress
• Fixed 4 bugs done

What’s Next

• Continue on fee system
• Continue work on withdrawals
• Continue work on BLS Rust Bindings
• Continue work on HTTPS for DAPI
• Same Block Execution integration
• Release Platform v0.23

Rust Port Update

Tasks

• Bring all changes from v23 into the Rust DPP port in progress
• Make previous JS DPP tests work with Rust DPP binding in progress
• Integrate Rust DPP into SDK, Drive, DAPI and test suite in progress

More detailed progress report

• Porting v23 changes: Previously we’ve finished 16/21, current state is 18/21
• Right now we’re finalizing the API between Rust DPP and JS parts of the project: How do we handle data types that are exclusive to JS, like Buffers
