It definitely not. The energy used turned to heat and eventually radiated away into the universe. Just like the energy used to find the largest prime number. Unless you think that energy is embodies in the number somehow but then where was the energy before the number was found? Because the number clearly already existed before it was found.

If you have embodied energy in something of no intrinsic value except as proof that you wasted some electricity, what you have is mere entropy. Burned toast.

Sometime, I think that "Proof of Work" is very similar to "Proof of Burn".

Usually in "Proof of Burn" you "burn" some cryptocoin sending it to an invalid address, and the blockchain has a proof that they are unrecoverable. (It was popular before someone notice that with an ICO you can have your cake and eat it too.)

In "Proof of Work" you "burn" a few barrels or petrol to produce electricity and then make some hash with the electricity, so if you find the correct hash it is a probabilistic proof that you burned the petrol. (You can cheat with other source of energy, like solar or wind, but they also have a cost.)

If anything it’s a record of energy transformed from electricity to heat, little else.

The energy isn’t still present in the Bitcoin.
