This denigration of signatures represents nothing less than an attack on the primacy of cryptography in cryptocurrency. The blockchain represents a complete and verifiable historical record of every transaction and balance in Bitcoin. Attacking verifiability by lopping off signatures in a misguided effort to cram more transactions into a megabyte. This leaves a eunuch which is no longer the virile Bitcoin we love. As signatures fade into history, cryptographic certainty is replaced by faith and hope.
