Bitcoin HTTP is the missing link in cryptocurrency infrastructure. TCP/IP proved we can transfer messages securely; BTC proved we can transfer money securely. But the true unlock of the internet was applications. So how can we get the same unlock on BTC? The solution is simple, and has been hiding in plane sight. The programmable Layer 1's of today were built under the stress of making new economies, new ecosystems, and competing with Bitcoin's dominance. However, this consideration was short-sighted as these chains lost access to a now $2.3 trillion asset and instead compete for fiat marketshare. The purchasing power of $1 in 1950 is equivalent to that of $0.07 in 2025. Chains are now eating the United States debt while China and other foreign powers are backing out. This is not sustainable and there is only one solution: Bitcoin. That's why @archntwrk decided to build a Layer 1 that: • Maintains state with Bitcoin • Constructs Bitcoin transactions • Offers seamless, instant finality for applications This may seem counterintuitive to investors and developers following the infrastructure battle for past decade. ~How it Works~ Arch validators run both a Bitcoin and Arch client. Through Distributed Key Generation, validators hold a share of a Bitcoin secret key proportional to their network stake-weight. And thanks to advancements in threshold cryptography, keys can be split among 100+ validators. Following so far? The Arch client is composed of a fork of the extended Berkeley Packet Filter virtual machine, the same virtual machine that Solana uses. In fact, from a developer's perspective, Arch feels just like Solana, using the same Instruction Set Architecture and Compiler. And the core team is in the final stages of developing their own version of Anchor, so smart contracts can be written in Typescript or Rust. Nodes reach consensus via Proof of Stake using the distributed Bitcoin keys mentioned above. Blocks are finalized when 51% of the validators send their signature, creating instant finality for Arch transactions. This combination of keys also enables validators to construct Bitcoin transactions submitted on Arch and roll them out directly on the Bitcoin base layer, secured by Arch's economic security. Accounts leverage the existing Taproot address space on Bitcoin, meaning there's no switching between wallets to access applications on Bitcoin<>Arch. Simply hop onto your existing Bitcoin wallet and instantly stake, borrow, or trade Bitcoin and UTXO assets such as Runes and Ordinals. All transactions are rolled up on Arch and settled directly on the Bitcoin base layer. ~This is the Future~ Arch is Bitcoin HTTP, acting as the only Layer 1 that takes Bitcoin settlement into account and extends BTC to the application layer. With increased adoption of Bitcoin, Taproot address space will grow exponentially as an access point to crypto. Arch provides the only way for these users to seamlessly benefit from permissionless finance. The solution is simple. Only on Arch, always on Bitcoin.
