NEAR protocol released a new version (2.0.0-rc.1) for the NEAR testnet. This update includes two major changes:
- Congestion control feature
- Stateless validation improvements
Key Points:
- Voting for the first change starts July 9, 2024, at 5:00 PM UTC
- Voting for the second change starts July 10, 2024, at 5:00 PM UTC
- This update requires changes to your database
- No security-related changes are included
Action Required: If you’re running a node on the testnet, you’ll need to:
- Update your software
- Make some configuration changes
- Possibly upgrade your hardware
Key Updates in NEAR Testnet Version 2.0.0-rc.1:
- Congestion Control:
- Limits transactions and receipts in overloaded shards
- New fields in chunk headers to indicate shard load
- Transactions may be rejected with “ShardCongested” error during heavy congestion
- Stateless Validation:
- Changes how nodes validate state transitions
- Introduces two roles: chunk producers and chunk validators
- Top 100 validators by stake become chunk producers
- All validators serve as chunk validators
- Hardware and Configuration Changes:
- For top 100 validators:
- Temporarily increase hardware capacity during upgrade
- Set
store.load_mem_tries_for_tracked_shardsto true - Initially set
tracked_shardsto [0], then to [] after upgrade
- For other validators:
- Set
store.load_mem_tries_for_tracked_shardsto true after upgrade - Set
tracked_shardsto []
- Set
- For non-validator nodes:
- Set
store.load_mem_tries_for_tracked_shardsto false
- Set
- For top 100 validators:
- Contract Changes:
- New size limits for transactions and receipts
- Increased cost for cross-shard communication
- Network Optimization:
- Recommended for all node operators
These changes aim to improve network efficiency and reduce resource requirements for most validators. Implementation will occur in stages, with voting for each protocol upgrade happening on separate days

In the coming days LNC will be running “Wheel of Transactions” to test the updated network.

The latest NEAR testnet update, featuring congestion control and enhanced stateless validation, marks a significant stride towards optimizing network efficiency and scalability. These improvements are crucial for supporting higher transaction volumes and reducing entry barriers for validators, enhancing the overall health and decentralization of the network.
