Round: 48 Date: 2018-02-01 Location: Albuquerque, NM, USA Commit version: d47a1d3d1f007063cbcc35f1ab902601a8b3bd91 SHA256 challenge file: 35b60456f4d4a17ceefb1acfd0371d7134789319649cfd6bf77aca35d2824950 Blake2b response file: The BLAKE2b hash of `./response` is: 7c220a51 5804a837 d314eb18 f861198f e1bff8e0 f3e4018f 68a6b2c6 8a4bc89b 59a80446 52cc2602 4c3f72f9 32730700 1bff8df0 429da619 70d6f587 72629732 Methodology ========= The hardware used was a mid-2011 MacBook Air running OS X 10.11.6. WiFi and Bluetooth were disabled and the MAC address of the WiFi adapter was blocked at my router. I transferred the challenge file via USB drive. I first attempted to use Filippo Valsorda’s golang implementation but ran into an issue where it was throwing an error, “Failed to read the challenge: point is compressed.” So, I ran the standard Rust implementation instead. Additional entropy was produced via a USB-connected keyboard. I again transferred the response and response hash via a USB drive to my network-connected laptop for upload. The MacBook Air and the USB drive used to do the compute was then destroyed. Just for fun, here’s an imgur album of the laptop destruction (yes, we made sure to avoid damage to the battery cells): https://imgur.com/a/IkG3i -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEE2eDG1CCBN16+WtTSC6+LqJ7Wy2QFAlpzmksACgkQC6+LqJ7W y2SkYQ/+OlYd79nl1EX6St7dgvbJvb2lZbP1qYG2dEdJsTY0yTILREPLwOfOlopJ DOm7hn2SGbi7FUe2XIMc07bi+shvH3h8mpKnSt9HYw/KtwAmgqt9o0DpbMNibOyw 8q9rDtmbgV8/Hg9GBDaR0V+ocy/uObdLehxb3zsm2gLToTOj4sEM75nje2zbhVSd +F/UN7qYNq5DwUIA/rqqPAA4EVaOa6zan8h803fIeokTNkw7bcIDiJkdbcZh8fko qcVEnRdhf4t0OS2ZIyGGQ8YU/EUhu8e1xvGj8aKZ+uzarMV6lgef7yOosMWbnjkh JHqEZnBXqqWGW4uslE8Flh68CmKAa7Z8gtnSOxfrIDCwN7IMM1bQzAI45yydLYCB 1rjJndasmmxkP+kzzAz0ixP6nEiMOnsNZibqTdi5kQjvytKQwm/viVeuAE5d24cM JBfBArbsug3ZvAKSgwuaboIC77/qhZYqYxxfGiM91g9KQsFrg7SXYpH3cf806JID RAHT/6z1M7RegjZL74BH74QB6tb2pVIDqDDnY9wp1Lj8PeiGx2u5+eiW71NYAX5h GtWThZrd5yk6+EBzsyIeRnPmf4oaw/Y0jMs8qePVHcaXDiWHAdwIg2lwmVfqZx80 lR5mSBmiV0tDX14SDgbQuONAqFtop102QZkawvR4ZbYPNpf/Jjc= =EmVb -----END PGP SIGNATURE-----
