# Bitlayer

Bitlayer, a Layer 2 protocol that leads the Bitcoin world into the new era of smart contracts, is not just about "accelerating Bitcoin", but rather forcibly equipping Bitcoin with a "smart brain".

• It is based on BitVM—an Optimistic Rollup architecture that does not undermine Bitcoin's foundation, elevating Bitcoin's non-Turing complete limitations to a Turing complete state. Through the DLC + BitVM architecture, it cuts off the trust risks of multi-signature bridges, allowing asset entry and exit without centralized control or backdoors, almost comparable to the security guarantees of BTC L1.

• More impressively, it is compatible with several VMs (including EVM, SolVM, MoveVM, and even CairoVM), making it incredibly easy for developers from the Ethereum ecosystem to migrate and engage in DeFi, NFTs, blockchain games, lending protocols... Bitcoin, which could previously only watch the excitement, suddenly possesses deep productivity.

• Architecturally, Bitlayer uses PoS rapid block production + Rollup for periodic submissions to Bitcoin L1’s “front-end settlement”, achieving “second-level soft finality” and “L1 reimbursement-style hard finality”, balancing efficiency with unbreakable security.

Is there actually just one step missing between technological ambition and reality?

• They claim that "security is equivalent to Bitcoin L1", but in reality: the main trust relies on the collective honesty of PoS validators (i.e., BTR staking nodes), which actually adds an assumption beyond Bitcoin itself; the security assertion still has "assumptions" supporting it.

• The current ecological layout is supported by AWS public cloud, having absorbed $5.5 billion TVL in just a few months, launched over 300 projects, and attracted over 70,000 users with a daily transaction volume of 150,000. While impressive, this raises questions: how decentralized is it? Has the most dangerous part been eliminated in front of the community?

• The most important native token $BTR, although already favored by venture capitalists such as Polychain, Framework Ventures, and OKX Ventures, with Series A funding exceeding $20 million, still faces numerous transparency issues regarding “launch time”, valuation, and token supply structure.

Summary: Is this a good horse, or merely a koi fish under the banner of "smart Bitcoin"?

In summary: Bitlayer represents a "smart revolution" in the Bitcoin world, daring to break through technological boundaries, and carries a strong sense of "early entrepreneurial spirit" and "1000 °F curiosity". If you appreciate a sense of technology, value security, and prefer playability, Bitlayer is undoubtedly a promising new player to watch; however, if you are an extreme decentralization advocate or particularly vigilant about sovereign control, you must realize that this "smart Bitcoin horse" has yet to spread its wings and is still an experimental entity tied to the AWS framework.
