What does it mean that the security of Bitcoin public keys and 256-bit ECDSA is 128 bits? ↗

What does it mean that the security of 256-bit ECDSA, and therefore Bitcoin keys, is 128 bits? I mean, if I have approximately 2^256 possible points on the elliptic curve (thus possible public keys),...

Can a blockchain's transactions be reversed? ↗

No, as far as we know, Ethereum transactions cannot be reversed. The DAO hack exploited a badly coded smart contract. The smart contract runs on top of Ethereum, so there are two layers involved he...

Is 24 words seed safer than 12 words in terms of bruteforcing the private key ↗

Regardless of whether you have a passphrase or not 12 words is just as secure as 24 words because the resulting public key will still require 2^128 iterations to compute its private key using the most...

Does a clearnet connection to my lightning node not require a TLS certificate? ↗

Lightning network connections do not use TLS or certificates at all, as far as I know (note that this may be different for other types of connections, like RPC). To explain why, let us look at how the...
