Currently, 500 of the S19 Pro Antminers have been delivered and deployed at the Data Center. The Data Center has the capacity to deploy up to 30,000 S19 Pro Miners that will generate 3.320 EH/s, providing Marathon with substantial opportunity for future expansion.

This low-cost electricity reduces Marathon’s breakeven costs to produce Bitcoin from approximately $7,500 per Bitcoin today to $4,600 per Bitcoin...

MuSig2: Simple Two-Round Schnorr Multi-Signatures

> we propose MuSig2, a novel and simple two-round multi-signature scheme variant of the MuSig scheme. Our scheme is the first multi-signature scheme that simultaneously i) is secure under concurrent signing sessions, ii) supports key aggregation, iii) outputs ordinary Schnorr signatures, iv) needs only two communication rounds, and v) has similar signer complexity as regular Schnorr signatures. Furthermore, our scheme is the first multi-signature scheme in the DL setting that supports preprocessing of all but one rounds, effectively enabling a non-interactive signing process, without forgoing security under concurrent sessions.
