At Arch, we've developed robust mechanisms that allow developers to harness Bitcoin's trust model, without sacrificing performance or reliability. Read about our rollback and reapply architecture 👇

Arch uses Titan, a custom-built Bitcoin indexer developed by @Saturn_btc, to power its high-performance transaction processing. Titan is specifically engineered to support Arch's unique architecture requirements, introducing pre-confirmations and rollback/reapply mechanisms.

The convergence of FROST and ROAST signature schemes represents a paradigm shift in Bitcoin programmability. Unlike traditional multisigs that requiring full participant honesty, Arch achieves robust consensus with only 51% honest validators.

Satoshi's mechanism was elegant: adoption creates value, value attracts adoption. The next mechanism builds naturally: infrastructure enables utility, and utility compounds value. The user base proved Bitcoin's worth. The builder base will prove its potential.

Bitcoin transactions takes longer to finalize. Thats slow for DeFi. Arch gives you instant feedback through pre-confirmations—see your trades and transfers immediately while Bitcoin does its thing in the background. The UX users expect, with the security Bitcoin provides.
