Keeping your ESG safe with Blockpool private chains

Blockpool’s datacentres run on more than 85% renewable energy according to its CTO, Tim Shank. “We offset the remainder,” he says.

“On top of that we participate in a carbon offset program that puts us solidly in the negative. We’ve analysed the energy usage of our chain and it comes in orders of magnitude less than anything that other chains have published. We will continue to add to that offset as we deploy for clients – licensing a private chain actually removes carbon from the environment.”

Blockpool is also a member of carbonfund.org – offsetting far greater than we consume for internal business processes and computing.

An analysis of our footprint is as follows:

Test CPU	Intel i7-10710U 6 cores, Hyperthreading Active, Clocked to 1.8GHz, 25W TDP, Turbo & Speedstep Off
5,000x	Empty block forge	12.0	Wh	Margin of error	– 0 Wh / + 0.499 Wh
5,000x	Full block forge	23.5	Wh
5,000x	Empty block validate	11.5	Wh
5,000x	Full block validate	22.5	Wh	Running iterations for individual txs was not realistic given the low usage.
Derived	Add transaction to block (unvalidated)	0.0153	mWh
Derived	Validate transaction in block	0.0147	mWh	Even 100k iterations would still have a 33% margin of error.
240 full blocks/hour * 150 transactions/block = 36,000 transactions/hour
4.7 mWh/full block forged + 4.5 mWh/full block validated * 100 peer validators = 454.7 mWh/block forged and validated
240 full blocks/hour * 454.7 mWh/block total cost = 109 W network usage @ 36,000 tx/hour
