Blockchain Sustainability Index

Many believe that Proof of Stake blockchains have solved the sustainability issues of blockchain. However, a closer look at the network reveals several factors that prevent an accurately calculated power consumption and CO2 emissions:

• Unlike Proof of Work, Proof of Stake reintroduces ownership and equity control over the network¹
• Each client in a Proof of Stake network needs to run a full node, which results in externalizing power consumption back to the clients instead of allowing thin, energy efficient, clients²
• Measuring Proof of Stake power consumption is difficult due to the lack of a reliable method for calculating the number of nodes.
• Fundamental issues with PoS make it impossible to solve the problem of distributed consensus, which could lead to even more power consumption and CO₂ emissions ³

These factors prevent us from providing accurate data on Proof of Stake power consumption and CO₂ emissions. As an example, although the estimated power consumption per transaction on Ethereum is 0.04KWh⁴, we anticipate its practical power consumption to be considerably higher given the previous reasons.

Bitcoin SV follows the original specification of the blockchain protocol called 'Bitcoin: A peer-to-peer electronic cash system'.

Most business value lies in a single shared global ledger for the provenance and traceability of information. Bitcoin SV has no caps on scalability and can deliver on this vision.

The value proposition of the blockchain is having a shared reference to the same source (of truth). Introducing multiple blockchains undermines this value proposition.

The original Bitcoin protocol was envisioned by Satoshi Nakamoto in 2008. Bitcoin SV is not the speculative technology under the ticker of BTC.
