Why NEAR did not need bunker mode, and has had post-quantum account keys on mainnet since July 20, in Illia's words: "We designed NEAR with quantum in mind in 2018." The account model lets you rotate keys, hold several at once, and mix cryptographic schemes. "I literally wrote that code. It takes about 200 lines to add a new cryptographic curve." So when the key-recovery papers started dropping this year, post-quantum was a new curve, not a new chain. ML-DSA went to mainnet in July. Any user rotates in one click, no asset move, no new address, no tax event. Other chains are writing roadmaps. NEAR wrote the extension point eight years ago.
