OriginTrail Mainnet Release V8.1.1-rc.4

The new V8.1.1-rc.4 node introduces a significantly upgraded execution engine. It brings overall performance improvement across all node operations, especially useful for the new V8.1.X features such as node sync and random sampling

DKG Core Node runners make sure to update your nodes!

🌟 Improvements

• Introduced BullMQ as new command executor

Note: BullMQ uses Redis as a dependency. The node will automatically set up Redis for you. We recommend checking the Redis config after the node update. To do so, open the /etc/redis/redis.config file and confirm that these 4 lines are present at the end of the file:

supervised systemd
appendonly yes
appendfsync everysec
maxmemory-policy noeviction

OriginTrail Mainnet Release v8.1.0

✨ DKG V8.1.0 release

The OriginTrail Decentralized Knowledge Graph (DKG) V8.1.0 mainnet release represents a significant upgrade in the evolution of the OriginTrail ecosystem. It introduces Random Sampling-based Proofs of Knowledge (PoK), enabling TRAC staking rewards and advancing toward the next roadmap milestone: the Metcalfe Convergence. With the release of V8.1.0: - TRAC delegators can now earn rewards based on verifiable data storage. - Core Nodes gain new automation and resilience capabilities. - Builders benefit from improved configurability.

This version finalizes the Random Sampling system and introduces new network mechanics, making it one of the most significant DKG upgrades to date.

🎉 Key Features

🔹 **Random Sampling Proof System**

• Purpose: Verifies long-term availability of Knowledge Assets.
• Mechanism: Nodes submit Merkle proofs in response to randomized blockchain-issued challenges.
• No setup required: Nodes start participating automatically.

🔹 DKG Sync feature

• Function: Allows nodes to fetch missing Knowledge Assets.
• Activation: Optional, requires manual enabling.
• Benefit: Boosts Node Health, ensuring better reward performance.

DKG Core Node runners: Make sure your node is updated. Consult the update guide for details: https://docs.origintrail.io/useful-resources/dkg-v8.1.x-update-guidebook

TRAC Delegators: Staking features will resume on June 26th 2025 when the staking UI will be updated, concluding the V8.1.0 release.
