♦ èveryone asking what @EspressoSys is and what is amouts to , my ans iis –

it’s not a chain , it’s the glue making all the rollups + validiums + appchains act like one

shared sequencer
hotshot orders txs from any chain
sub‑1s finality so arb, op, zksync can all talk instantly

DA layer
erasure‑coded data + KZG proofs
validiums save 90%+ on calldata
still cheap to verify on L1

atomic cross‑chain
flash loans, swaps, arbitrage across rollups in one block
no relayers, no multisigs
consensus enforces it

rollups ditch their own sequencers
L2s + L3s plug in easy
users get fast bridging, cheap fees, and no silos

espresso basically makes the rollup world feel like one network
fast, modular, and trust‑minimized
