#Bitlayer
You asked: "Bitlayr what is" — It seems you’re referring to Bitlayer (sometimes stylized “Bitlayr”), a prominent Bitcoin Layer-2 project. Here’s a clear breakdown of what Bitlayer is:
What Is Bitlayer?
Bitlayer is a Bitcoin Layer-2 (L2) protocol designed to bring advanced programmability, smart contracts, and scalability to the Bitcoin network, while inheriting its robust security. It achieves this through an innovative computing paradigm called BitVM, combined with rollup-style mechanisms and zero-knowledge proofs.

Key Features💥
Security Anchored to Bitcoin
Bitlayer settles its state onto Bitcoin’s main chain, ensuring Bitcoin-equivalent security through recursive verification and BitVM-based fraud-proof mechanisms.

Turing-Complete Smart Contracts
Unlike Bitcoin’s limited scripting, Bitlayer enables fully expressive smart contracts via BitVM.

EVM Compatibility🔥
It supports the Ethereum Virtual Machine (EVM), allowing developers to port and deploy Ethereum-based dApps directly on Bitlayer.

Scalability with Rollups💥
Bitlayer batches and aggregates transactions off-chain, then settles state updates onto Bitcoin with cryptographic proofs, similar to rollups on Ethereum but adapted to Bitcoin’s environment. Its V2 upgrade introduces a hybrid of ZK proofs and fraud proofs with challenge periods — reducing settlement costs while retaining trust.

Bridges and Interoperability
It features secure asset bridges (BitVM Bridge) using DLCs and OP-DLC technologies for trust-minimized transfers between Bitcoin and Layer-
