The Miner as an Engine
A bitcoin miner is a thermodynamic engine. Just as a traditional heat engine converts thermal energy into mechanical work, a bitcoin miner converts electrical energy into computational work and heat.
Input: Electrical energy (low entropy, highly ordered)
Outputs: Computational work (maintaining the bitcoin blockchain, creating new bitcoins)
Heat (high entropy, dispersed energy)
The Second Law of Thermodynamics
states that the entropy of an isolated system always increases over time. Bitcoin mining exemplifies this principle. The process starts with low entropy electrical energy, concentrated in the power supply. Some of this energy becomes ordered information in the bitcoin blockchain. A significant portion is converted to heat, increasing the overall entropy of the system.
This increase in entropy is not just a byproduct but a fundamental aspect of the mining process. The heat generated by miners is a direct manifestation of this entropy increase, making it an integral part of the system rather than waste.
Like traditional heat engines, the Bitcoin mining process is irreversible. You cannot convert the generated heat back into the original electrical energy or computational work. This irreversibility describes entropy increase and is part of the nature of the energy transformations involved in mining.
Just as with traditional engines, there are theoretical and practical limits to the efficiency of miners. Not all the input energy can be converted to useful work (in this case, hashing). This limitation is the same thermodynamic principles that govern the efficiency of any energy conversion process.
Consider the entire Bitcoin network as a distributed thermodynamic engine. A global system that converts electrical energy into digital value and heat, with an overall increase in entropy.
