Why this block matters
This block shows very strong signals of solo mining — no shared-pool payout pattern was detected and the confidence score is high.

- Payout address has never received a block reward before — consistent with solo mining
- Mined against 0 EH/s of total network hashrate — statistically rare for solo mining
- Found 33m 00s after the previous solo candidate (#283,571)
