See the miners inside OCEAN
OCEAN appears as one pool. DATUM lets individual miners build their own blocks. Blokzs shows the difference.

The missing layer
mempool.space says “OCEAN mined this block”. We say who built it.
02
OCEAN
Explorers attribute the block to the pool. The trail stops there.

DATUM miners / OCEAN templates
Blokzs separates miner-built DATUM blocks from direct OCEAN templates.
DATUM vs OCEAN
Every OCEAN block classified as DATUM-built or OCEAN-built from coinbase structure — never guessed.
Adoption over time
See decentralized template construction grow block by block across the checkpoint.
DATUM miner identities
Secondary coinbase tags shown exactly as published — cc, 888, or any arbitrary string.
No invented attribution
Tag text is identity, not proof of company names. Classification uses structural coinbase encoding only.
Decentralization you can actually see.
