If bitcoin were to ever consider changing their PoW algorithm a little, it seems that would immediately make purchased ASIC mining equipment partially or wholly unusable to compromise the chain (and temporarily reduce energy usage without necessarily reducing security). One possible plan to deter a multibillionaire attack.
Also regarding the word "security" here, a 51% attack impacts some parts of chain operations, but not others. It seems to me bitcoin's biggest vulnerabilities are either covert compromise of mining pool operations, or widespread compromise of networked mining systems and client nodes. Far easier than outcompeting the mining network with hardware. I don't see why it would necessarily be made public if a government compromised their nation's mining farms. Governments have skilled operatives for things like that. People would guess it happened, and the government would cover up the guesses with more powerful stories. _______________________________________________ bitcoin-dev mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
