BOINC project Greylisted · automatic Snapshot 2026-11-11

DENIS@Home

4 of the project's 1 207 users with RAC have a Gridcoin CPID, but together they bring only 0 % of its credit rate, and it is greylisted: the chain pays no magnitude for it while it is.

Greylisted (automatic) since superblock 2 872 796 (2025-06-01). The chain pays no magnitude for a greylisted project, and pays it again from the first superblock that no longer lists it as greylisted.

About DENIS@Home

Biology and medicine

Simulates the electrical activity of the heart, to study heart disease and how drugs affect the heart.

Run by Universidad San Jorge in Spain (the CoMBA research group). The project builds mathematical models of the heart's electrical activity. Studying them takes many simulations with different conditions and parameters, and those are what the volunteers' computers run.

The project announced on 19 March 2026 that its work is paused for a while, because its lead researcher took on a management role at the university. It gave no date to start again.

What it says

19 of the last 20 superblocks brought no new credit, so ZCD is 19, above 7. The credit of the last 7 superblocks against the usual gives a WAS of 7.81, not below 0.1. Both are why the wallet has greylisted it: no magnitude is paid.

What brings it back

New credit in each of the next 12 superblocks brings ZCD to 7 or less (about 12 days at one superblock a day).

What the chain has about the project: the contracts that put it on the whitelist and keep it there, and what the superblocks did with it. The newest superblock, 3 334 498 (2026-11-11), lists the project on the greylist, so it is not paid. The whitelist is renewed about twice a year (the contract is removed and added again); a renewal that changes nothing is left out unless asked for.
