What happened to Bitcoin L2s
summary
A blunt post‑mortem of the 2023–2026 Bitcoin Layer‑2 season: hundreds of rollup/bridge projects raise funding and then vanish or turn into tokens, while a handful produce lasting primitives — BitVM paper enables on‑chain proof verification, state‑chain and BTM bridge designs iterate to BTM2/3, and Arc/Spark/Cashu solve real UX and exit problems. Spam via inscriptions proves technically unstoppable despite client forks (Bitcoin Knots/BIP110) so usage economics wins: most casinos die, the pragmatic L2s keep building.
