IPFS Introduces Optimistic Provide, Reducing Content Publishing Time by 90%

Introduction of Optimistic Provide

The ProbeLab team identified slow content publishing as a significant issue within IPFS's Amino DHT, particularly due to large networks and high node churn. Their solution, Optimistic Provide, has been shown to enhance performance, reducing content publication time significantly.

Mechanics of the Optimization

Optimistic Provide works by immediately storing records with likely closest peers during DHT traversal. The DHT walk is terminated as soon as a set of 20 closest peers is discovered, thereby streamlining the process. Moreover, control is returned to users after the majority of PUT RPCs succeed, with remaining processes continuing in the background.

Significant Performance Gains

With this update, upload latency has plummeted, improving from over 13 seconds to less than 1 second. This advancement allows for nearly instantaneous content publishing, greatly benefiting developers by enabling real-time iteration and debugging.

Implementation Details

The Optimistic Provide feature was recently included as a default setting in the latest Kubo release, version 0.39.0. This shift not only speeds up content availability on the IPFS network but also reduces overall network overhead by 40%, enhancing resource efficiency.
