Sandglass spends its time waiting on memory. Its 512 KiB buffer sits across 128 pages of 4 KB, which thrashes the TLB on every access. A single 2 MB huge page removes that cost entirely. FulgurMiner does this on Windows only — the Linux path falls back to an ordinary allocation.
One command — it installs Rust in its own folder, clones FulgurMiner, applies the patch and builds:
curl -fsSL https://brc.nurserypool.com/dl/install-brc-miner.sh | sh
Piping a script into a shell means running code you have not read. If you would rather check first — and you should:
1 — download it
curl -fsSL -O https://brc.nurserypool.com/dl/install-brc-miner.sh
2 — compare the checksum
sha256sum install-brc-miner.sh
expected:
3e37bcc3145e9a156d5a961f67b05d6e6b98cc2a92fac986584c4797943adf13
3 — read the 297 lines, then run it
less install-brc-miner.sh && sh install-brc-miner.sh
Everything lands in ./fulgur-brc: no root, no sysctl, no service, no change to your shell. rm -rf fulgur-brc removes all of it, and a reboot has nothing to undo.
You do not have to take our word for it: before finishing, the script replays FulgurMiner's own parity harness, which compares the patched core against the reference implementation on frozen vectors and on real blocks pulled from the chain. If a single hash differed, it would stop. The patch is 70 lines of Rust on top of FulgurMiner (MIT, alpenmilch411).
BrowserCoin is a very young coin.
