In today’s world, many governments and interest groups are focused on reducing emissions and pollutants. While I support the development of more efficient technologies, I believe that we must also consider the costs of eliminating valuable or lifesaving technologies.

Related to that topic, some critics of Bitcoin have unfortunately proposed eliminating it altogether, citing its high energy consumption. For example, earlier this year, Robert Altenburg, a leader of one of the aforementioned interest groups, testified before the U.S. Senate against Bitcoin and its Proof-of-Work (PoW) consensus mechanism. Altenburg’s testimony was full of red herrings and strawman arguments, but I would like to focus on two of his most egregious claims:

Bitcoin is not a waste of energy.

Altenburg argues that Bitcoin is a wasteful technology that accomplishes nothing. He points to the fact that Bitcoin mining consumes a significant amount of energy, and he suggests that this energy would be better spent elsewhere. However, Altenburg fails to consider the value that Bitcoin provides.

Bitcoin is a decentralized, secure, and scarce digital asset. It is the only cryptocurrency that has achieved widespread adoption, and it's used by millions of people around the world. Bitcoin is also a valuable store of value, and it has the potential to revolutionize the global financial system.

The energy that Bitcoin mining consumes is not wasted. It's used to secure the Bitcoin network and to process transactions. The Bitcoin network is the most secure and reliable blockchain in existence, and is able to process millions of transactions per day.


 


Proof-of-Stake is not a viable alternative to Proof-of-Work.

Altenburg also argues that PoS is a viable alternative to PoW. He claims that PoS is more efficient and less energy-intensive than PoW. However, there are several weaknesses to PoS that make it an extremely unattractive alternative to PoW.

First, PoS is more susceptible to centralization. In PoS, validators are chosen based on the amount of cryptocurrency they hold. This means that large holders of cryptocurrency have a greater influence over the network. That centralization can make the network more vulnerable to attack.

Second, PoS is more vulnerable to manipulation. In PoS, validators can be bribed to both propose and approve fraudulent transactions. This could be used to censor transactions or to double-spend coins.

Third, PoS is less secure than PoW. In PoS, validators are not required to expend any resources in order to process blocks. This makes the network more vulnerable to attack.

For these reasons (and others), I believe that PoS is not a viable alternative to PoW. PoW is a more secure, decentralized, and efficient consensus mechanism.

Leave Bias Behind

Each of us enters the Bitcoin space with our own biases about what it is and what value it brings to us and to society. In no small way, coming to truly understand Bitcoin is as much about dismantling those biases as anything else.
