Introduction

Bitcoin is the king of blockchains—secure, decentralized, and battle-tested for over a decade. But despite being the world’s most trusted digital currency, Bitcoin struggles with speed, scalability, and programmability. Enter Bitlayer: a cutting-edge Layer 2 solution that takes Bitcoin beyond simple transactions, turning it into a platform for smart contracts, decentralized finance (DeFi), and cross-chain innovation.

At its core, Bitlayer blends Bitcoin’s rock-solid security with Ethereum-like flexibility, powered by the revolutionary BitVM paradigm. This makes it possible to build applications on Bitcoin that were once thought impossible.

Why Do We Need Bitlayer?

Bitcoin is strong, but not limitless. Here’s what holds it back:

Slow and expensive transactions – Bitcoin’s base layer prioritizes safety, which limits how many transactions it can handle.

No native smart contracts – Unlike Ethereum, Bitcoin wasn’t designed for complex applications, leaving developers with fewer options.

Weak interoperability – Moving Bitcoin across chains often requires trust in centralized bridges, which goes against Bitcoin’s principles.

Bitlayer is here to solve these pain points while keeping Bitcoin’s decentralization intact.

The Vision Behind Bitlayer

Bitlayer’s goal is simple yet ambitious: scale Bitcoin without changing what makes it special. Its vision includes:

Bringing high-speed scalability to Bitcoin.

Powering BTCFi—Bitcoin-based financial products and services.

Enabling Turing-complete programmability, allowing advanced dApps to flourish.

Creating a trustless BTC bridge, so Bitcoin can freely move across ecosystems without middleme

What Makes Bitlayer Different?

Think of Bitlayer as a bridge between Bitcoin’s rock-solid foundation and the modern demands of DeFi and Web3.

It’s the first rollup purpose-built for Bitcoin, not just an add-on.

It’s EVM-compatible, meaning Ethereum developers can bring their apps over with almost no extra effort.

It runs on BitVM technology, bringing smart contracts to Bitcoin without sacrificing security.

In short: Bitlayer transforms Bitcoin into a platform where innovation isn’t just possible—it’s limitless.

The Tech That Powers Bitlayer

Bitlayer introduces a new balance between scalability and security through a unique rollup model:

Trustless Entry & Exit – Assets can move in and out of Bitcoin L1 safely, without needing custodians.

Rollup Architecture – Transactions are bundled off-chain, then verified on Bitcoin’s base layer for maximum security.

Hybrid Proofs (BitVM2) – Combines zero-knowledge proofs (fast and private) with optimistic fraud proofs (secure and challengeable).

Challenge Window – A seven-day open verification period ensures no fraudulent state goes unchecked.

On top of this, Bitlayer supports multiple virtual machines (EVM, SolanaVM, MoveVM), making it a flexible environment for developers.

Key Features at a Glance

EVM Compatibility – Deploy Ethereum apps directly on Bitcoin.

BitVM BTC Bridge – A secure and trust-minimized way to move Bitcoin across chains.

Bitcoin-Level Security – All state transitions are ultimately verified on Bitcoin L1.

Flexible Data Availability – Developers can choose between Bitcoin-native and external data solutions.

The Road Ahead

Bitlayer’s growth is planned in clear stages:

1. Stage 1: PoS Mainnet (V1) – Launched in April 2024 with EVM compatibility, ultra-low gas fees, and multisig security.

2. Stage 2: Rollup Mainnet (V2) – Coming in 2025, with a native Bitcoin rollup and BitVM-based BTC Bridge.

3. Stage 3: Supercharged Rollup – By late 2025, aiming for 20,000 TPS and lightning-fast confirmations.

Bitlayer isn’t just building for now—it’s setting up Bitcoin for the future.
