After this PR, every `.sszs` files of a given epoch (so, up to 32 files with the current `SLOT_PER_EPOCHS` value) are processed in parallel. **Which issues(s) does this PR fix?** - https://github.com/OffchainLabs/prysm/issues/16204 Tested on - [Netcup VPS 4000 G11](https://www.netcup.com/en/server/vps). **Before this PR (3 trials)**: ``` [2026-01-02 08:55:12.71] INFO filesystem: Data column filesystem cache warm-up complete elapsed=1m22.894007534s [2026-01-02 12:59:33.62] INFO filesystem: Data column filesystem cache warm-up complete elapsed=42.346732863s [2026-01-02 13:03:13.65] INFO filesystem: Data column filesystem cache warm-up complete elapsed=56.143565960s ``` **After this PR (3 trials)**: ``` [2026-01-02 12:50:07.53] INFO filesystem: Data column filesystem cache warm-up complete elapsed=2.019424193s [2026-01-02 12:52:01.34] INFO filesystem: Data column filesystem cache warm-up complete elapsed=1.960671225s [2026-01-02 12:53:34.66] INFO filesystem: Data column filesystem cache warm-up complete elapsed=2.549555363s ``` **Acknowledgements** - [x] I have read [CONTRIBUTING.md](https://github.com/prysmaticlabs/prysm/blob/develop/CONTRIBUTING.md). - [x] I have included a uniquely named [changelog fragment file](https://github.com/prysmaticlabs/prysm/blob/develop/CONTRIBUTING.md#maintaining-changelogmd). - [x] I have added a description with sufficient context for reviewers to understand this PR. - [x] I have tested that my changes work as expected and I added a testing plan to the PR description (if applicable).
Prysmatic Labs Beacon Chain Implementation
This is the main project folder for the beacon chain implementation of Ethereum written in Go by Prysmatic Labs.
You can also read our main README and join our active chat room on Discord.
Also, read the official beacon chain specification, this design spec serves as a source of truth for the beacon chain implementation we follow at Prysmatic Labs.
