Blocks

The real chain, as it happens. The chord changes when the next block is found, which can take a while.

A block's song

Every block has its own transmission. It opens with a call sign drawn from its hash, sent in Morse, reads out its number, then signs off. The same block always has the same call sign. Try a birthday, a halving (840000) or genesis (0).

How it plays

Blocks → numbers

Each new block is announced the way a numbers station would: three pips, then its height, read in two groups.

Hashes → chords

Under the static, a faint organ holds the chord the block's hash picked. While it waits, it drifts back through the last eight blocks' chords.

The wait → static

A block takes ten minutes on average but can take forty. The longer none comes, the louder the hiss and the higher the whistle drifts.

Adjustments → key, halvings → octave

Every difficulty adjustment, the station retunes on air and the organ moves to a new key. Every halving drops it an octave, for good. Countdowns to both are read out along the way.

Mempool → crackle

Transactions waiting to be mined crackle on the line. A busy mempool is a storm of static.

No prices anywhere in the music. Blocks and transactions only.
