Everything the scanner knows, as it knows it.

What this page is.

The paper explains. This page only reports. Every figure below is read from the machine's own tables once a second. Where a slot is empty, the machine has nothing to say yet.

Sector map

UNOPENED1 TO 9 CHUNKS10 TO 99100 OR MOREWORKING NOW
The range of the target as 4,096 sectors, lowest key at the top left, highest at the bottom right. A sector's color is how many chunks of 1,024 keys have been checked inside it.

One key, start to finish

The derivation below is not an example. It is the first key of the newest chunk, carried through every step the scanner performs, next to the target it was compared against.

PRIVATE KEY
32 bytes, a whole number inside the range
PUBLIC KEY
33 bytes: one byte for the sign of y, then x
SHA-256
32 bytes
RIPEMD-160
20 bytes, the hash160
ADDRESS
version byte, hash160, four checksum bytes, in base 58
bit 0bit 159
This key's hash against the target's, bit for bit. Orange is the run that agreed from the start. The black cell is where they parted. Everything after that is chance.

Self test

Before it was pointed at anything open, the scanner was run across the first twelve puzzles, which were claimed long ago. It was given only their addresses. These are the keys it found.

With k keys checked, the best match is expected to sit near log2 k bits. A figure far above that would be worth a second look. A figure near it is exactly what an honest machine and an unbroken hash produce.
