STP 13 (Proposal Blue Sky): An Evolution of Bitcoin with Far Less Carbon Emission


This STP, named Blue Sky, proposes B20, an evolution of Bitcoin with far less carbon emission. If passed, B20 will be fairly and 1:1 airdropped to all Bitcoin holders as if it were a straightforward Bitcoin fork. There will be no pre-mining, new issuance, or ownership misappropriation.

B20 will follow Bitcoin’s mining schedule but will be upgraded to PoS mining. While Bitcoin holders may claim their 1:1 B20 anytime, the PoS mining rights of all unclaimed B20 will be proportionately assigned to BTCST holders, who can then participate in B20 PoS mining as if their BTCST’s were B20's.


The cryptocurrency industry is at a crossroad. While blockchains have proven that distributed ledgers could be far more trustworthy, efficient, and versatile than legacy centralized data recordation methods, some opinion leaders have criticized what they perceive as unreasonably high energy expenditure.

Supporters of Bitcoin’s Proof of Work consensus algorithm view that the absolute amount of energy consumed by Bitcoin is in fact low compared to traditional financial systems. For example, according to a Greenpeace and WWF study, traditional banks relying on non-blockchain ledgers were directly and indirectly linked to 805 million tons of carbon dioxide emission in 2019. The Proof of Work proponents therefore view the energy consumed as necessary and acceptable.

Others disagree. According to the Cambridge Bitcoin Electricity Consumption Index, the Bitcoin network consumes 87.67 TWh per annum. If Bitcoin were a country, its annual energy consumption would rank between Finland (84.21 TWh) and Kazakhstan (91.67 TWh) as of 2019. To castigators of energy expenditure intrinsic to Bitcoin’s Proof of Work arms race, the point is not whether this level of power consumption is worthy, justifiable, or low compared to the banking system — all could be true. They view such exorbitant spending as wasteful and displacing those with more pressing energy needs.

Members of Standard Hashrate Group (SHG) have Proof of Work roots, but as a progressive organization, we are open to industry adaptations for Bitcoin iterations that optimize environmental impact. Now, after intensive consultation with industry experts and business leaders, SHG is proposing B20, a Bitcoin evolution with far less carbon emission.

B20 is not a synthetic τAsset. B20 is a new token to be fairly and 1:1 airdropped to all Bitcoin holders as if it were a straightforward Bitcoin fork. Specifically, if this STP is passed, B20 will launch with the following parameters.

  • Targeted Launch Block: Bitcoin Block 692692 (about 30 days from the date of this proposal)

Supported by members of the SHG and additional industry leaders to be announced, B20 as a Bitcoin evolution will leverage the BSC infrastructure and BTCST’s hashrate tokenization protocol to optimize Bitcoin’s energy consumption by more than 99% and improve Bitcoin’s block speed. SHG welcomes the BTCST community to vote on this monumental STP.

Bitcoin Standard Hashrate Token (BTCST) brings exchange-grade liquidity to Bitcoin mining. Each BTCST is collateralized by real Bitcoin mining power.
