Ark Labs is scaling #Bitcoin with Ark, a new layer two protocol for fast, low-cost, seamless payments.

Ark Labs raised $5.2M to build programmable finance on Bitcoin, with participation from @Tether, @EgoDeathCapital, @anchorage & others. The largest, most liquid digital asset gets the programmable infrastructure modern financial applications require, starting with stablecoins.

Bitcoin's volatility isn't a problem to solve. It's a yield opportunity. We love this take from @BitwiseInvest's @dgt10011. The next chapter for Bitcoin treasuries involves making BTC productive: monetizing volatility, generating organic yield, compounding the balance sheet.

The ol' website just got a facelift! Our vision for open programmable finance keeps evolving, and now the look matches the ambition. If you're curious about what we're building, start here 🔽

Read our full technical blog post for implementation details and architecture diagrams github.com/ArkLabsHQ/taproot-a...… Of course, this approach extends far beyond a technical demonstration. Imagine atomic, instant swaps between tokens and BTC—all on Bitcoin. USDT ↔ BTC virtual swaps,

Our proof-of-concept is open source. Yes, we have code! Check it out: github.com/ArkLabsHQ/taproot-a...… It includes a CLI for constructing colored Ark batches, tapd integration, and dockerized environments for Regtest and Signet. Try commands like mint, board, round, and unilateral exit!

Watch our technical walkthrough! This demonstration covers the full lifecycle from asset issuance to offchain token management to unilateral exit. You'll witness interactions between Onboarding Users, Exiting Users, the Ark Operator, and the Bitcoin network.

For unilateral exits, tVTXOs contain Transfer Proofs that verify an asset's path through the tree. These are activated with blockchain metadata (headers, hash, height, tx index), binding to onchain state. Here's a real exit on signet!

Our implementation, Colored Trees, developed by @boringprimate, allows VTXOs to represent both BTC and tokens while maintaining unilateral exit rights. The system recursively computes Asset Commitments and assembles Transfer Proofs at each transaction for deterministic outcomes.

Taproot Assets naturally fit into Ark's transaction batching architecture. tVTXOs embed asset commitments using Taproot's internal key and TapTree structure, functioning identically to regular VTXOs while carrying the additional asset proof data needed for token operations.

Some asked what we've been cooking 🧑‍🍳 We're pleased to report we recently completed a prototype integration of @lightning's Taproot Assets into the Ark protocol, unlocking tokenized VTXOs (tVTXOs)! New opportunities for efficient and secure token operations on Bitcoin! 👇
