Pearl status: what is live, in development, and still unverified

• Mainnet has run since April 27, 2026, and passed block 130,000 on October 19.
• The current core release is v1.5.2 (Oct 17, 2026), a fix on top of v1.5.0 “Security hardening”, which every operator was told to install as soon as possible.
• The current desktop wallet is v3.0.0 (Oct 13, 2026).
• Pearl Research Labs’ website now leads with a commercial inference platform: a serverless API plus managed and on-premise deployments.
• Together AI’s Pearl-powered Gemma endpoint, announced in May, is still presented on Pearl’s network page.
• An FP8 version of the protocol is specified and in development. It is in no release and has no activation height.

September and October were about hardening. v1.4.6 raised the minimum peer version and added checkpoints; v1.4.8 moved peer discovery to new seeders; v1.4.11 fixed wallet sends. Then v1.5.0 bundled a batch of security fixes reported by outside researchers, and v1.5.1 and v1.5.2 followed within four days.

There were no new forks after August’s salted noise-seed hard fork at block 99,000. The development branch, meanwhile, gained code for a fourth certificate version built on FP8 arithmetic.

No explorer, coin price or total-work figure answers Pearl’s central question. The defining metric is the independently verifiable share of network work attached to genuine training or inference.

The only published measurement, a study of late May, predates four protocol changes. Until a new one appears, “proof of useful work” is a safer description of what the protocol can do than of what all observed mining does.
