Threshold-optimal DSA/ECDSA signatures and an application ...

"If ECDSA is broken, Bitcoin can remain reasonably secure if you don't reuse addresses." Is this true?

If this is actually true, what makes it true?
That post is pretty old. Has anything significant changed? What's the recommended best practice these days if you need to reuse an address? For example you are a business and need to have a single address that can be published and it wouldn't be practical to keep constantly changing it?
Is this also actually true: "(That is, an address's sent transactions might not actually be meaningful, related to its receipts, or even made by the person who receives money at that address.) "? If so, why would that be the case? It sounds like the OP is suggesting an address can somehow "send" bitcoins that it never "received" - how can that be?

Time to replace ECDSA with with post-quantum cryptography to secure the future of Bitcoin.

Crucial hurdle overcome for quantum computing
The development of scalable quantum silicon chips is moving faster than expected. ECDSA is considered broken by Shor's algorithm. Upgrade Bitcoin before it's too late!

First, if ECDSA were broken, a lot of other things would be broken, like ssh, https and a bunch of other things, including banking websites. Second, if nobody reused addresses, then yes, bitcoin would be protected by SHA256 and RIPEMD160. There is currently no known way to get a preimage of a hash used by either of those functions so your ... Elliptic Curve Digital Signature Algorithm or ECDSA is a cryptographic algorithm used by Bitcoin to ensure that funds can only be spent by their rightful owners. A few concepts related to ECDSA: private key: A secret number, known only to the person that generated it. A private key is essentially a randomly generated number. In Bitcoin, someone with the private key that corresponds to funds on ...

PDF On Dec 30, 2016, Pratyush Dikshit and others published Weighted threshold ECDSA for securing bitcoin wallet Find, read and cite all the research you need on ResearchGate The security of Bitcoin mostly relies on the security of ECDSA algorithms. This thesis covers the steps of understanding how ECDSA works, and how it is used to create a new Bitcoin transaction. Also the speed performance in signature generation is measured and improved. Based upon it, di↵erent versions of security countermeasures are implemented to protect against side channel attacks ...
