hermaion · series 2

Series 2 is open. Your fix is pinned to the next Bitcoin block after your payment lands. When that block is mined it carries a 256-bit hash that no one could have known a moment earlier. Your Lightning preimage and the block hash are run through SHA-256, and the 64-hex-digit result is the seed.

From the seed the cast is mechanical. Take the first six hex digits; each is one line, read bottom to top, by the yarrow proportions — a 0 is old yin (changing), 1–5 young yang, 6–C young yin, D–F old yang (changing), the 1/16, 5/16, 7/16, 3/16 the stalks make. Solid lines (7, 9) are yang, broken (6, 8) yin. The bottom three lines form the lower trigram, the top three the upper, and the King Wen table turns that pair into one of the sixty-four. Any changing line then flips to its opposite — old yin to yang, old yang to yin — and a second hexagram rises behind the first: the “into,” the before-and-after.
