Editorial interest 86/100 Selection signal · not a rating of the site

Credibility concern recorded. The source reference remains available for verification and correction.

A standalone BLAKE2b proof-of-work chain designed around a fixed cryptographic challenge, a millionfold denomination shift, and balances that decay unless owners periodically defend them.

Landing page captured for the 2026-09-11 issue.

Field notes

The chain combines BLAKE2b-256 mining with a fixed Edwards25519 challenge that enters the ordinary mempool and triggers after six confirmations. Its post-event accounting is deliberately unusual: a displayed coin shifts from 10^24 to 10^18 atomic units, while each output stays fully spendable for 1,440 blocks before decaying in 60-block steps over the following 10,080 blocks. The homepage also exposes a premine address, burn schedule, network ports, and multi-platform releases.
