What Is A Carbon Negative Bitcoin Block?

This is a guest post from Luxor’s Hashrate Index.

A miner with roughly 1 exahash (EH) of Bitcoin’s hash rate is advertising its blocks as “carbon negative.”

So, how can a miner produce work and leave a negative carbon footprint, seemingly reversing entropy?

Well, the short answer is, of course they can’t, but how can they claim carbon negativity at all?

The miner has been blazoning its allegedly carbon negative activities using the OP_RETURN field. The epigraph has been etched into five blocks so far.
