Kardashev Scale Quantum Computing for Bitcoin Mining

Bitcoin already faces a quantum threat through Shor attacks on elliptic-curve signatures. This paper isolates the other component that public discussion often conflates with it: mining. Grover's algorithm halves the exponent of brute-force search, promising a quadratic edge to any quantum miner o...

CVE-2025-65548

NUT-14 allows cashu tokens to be created with a preimage hash. However, nutshell cashubtc/nuts before 0.18.0 do not validate the size of preimage when the token is spent. The preimage is stored by the mint and attacker can exploit this vulnerability to fill the mint's db nd disk with arbitrary da...

CVE-2025-65548

CVE-2025-65548 affects Nutshell (cashubtc/nuts) prior to 0.18.0. The issue is that when spending a token, the preimage size is not validated, and the preimage is stored by the mint, enabling an attacker to fill the mint’s database and disk with arbitrary data. Public sources consistently describe...
