Despite the narrow focus, the conversation that ensued – which many industry experts appraised as a meaningful educational experience for the lawmakers – touched upon a range of blockchain-related issues and themes beyond energy consumption. Here is how it went down, and what comes next.
Following the opening remarks, the hearing kicked off with the witnesses delivering their testimonies. Bitfury CEO Brian Brooks made a point that it was up to the market to decide on the most productive ways to use the already produced energy and maintained that proof-of-work (PoW) is the consensus mechanism that is best suited to produce true decentralization of a blockchain network.
In contrast, Cornell Tech professor Ari Juels, while speaking favorably of blockchain technology and Bitcoin (BTC) in particular, maintained that proof-of-work is unnecessarily wasteful while the downsides of the alternative proof-of-stake, or PoS, mechanisms are largely theoretical.
John Belizaire of Soluna Computing stated that Bitcoin’s energy consumption should be seen as a feature rather than a bug because crypto mining can create efficiencies by using the excess renewable energy. Steve Wright, a former general manager of a public utility district in Washington state, shared his experiences of interacting with crypto miners who flocked into the area due to abundance of cheap electricity, while former acting assistant secretary of the U.S. Treasury Gregory Zerzan introduced multiple uses of blockchain technology and said that regulatory uncertainty could hurt
