OVERVIEW

Bitcoin Secured, Built for Your Use Case

BitVM Network is a modular framework for building Bitcoin anchored multi-sidechains. Rather than a single fixed design, it offers a set of interchangeable components peg mechanism, consensus, and execution environment that can be assembled into zero knowledge, federation backed, or fully trust minimized deployments depending on what a given project needs

Every configuration shares the same foundation: settlement and security anchored to Bitcoin. What changes between deployments is how the peg is secured and what kind of execution environment sits on top, so teams can start with a familiar federation based model and move toward a more trust minimized design as BitVM tooling matures, without re architecting the application layer

Positioning

BitVM Network is infrastructure for teams that want to extend Bitcoin, not a single hosted product. Its component model is meant to support use cases ranging from consortium networks to fully public, trust minimized sidechains

Modular by Design

Peg, consensus, and execution are independent layers that can be mixed and matched per deployment

Why A Sidechain

Extend Bitcoin Without Changing It

Bitcoin is a deliberately conservative settlement layer, which is exactly what makes it durable but that same conservatism means it isn't designed for complex application logic. A sidechain lets a team build the execution environment their product needs while still settling back to Bitcoin

Who Does What

Two Ways to Secure Your Peg

Every BitVM Network deployment needs a way to move value between Bitcoin and the sidechain. Two peg models are available, trading off differently between operational simplicity and trust minimization

Variant A · Federation + Merge Mine

Fast, familiar, and protected built around a federation and Bitcoin's own proof of work

A k-of-n federation manages the peg

AuxPoW consensus rules tie block production to Bitcoin mining

Predictable operations and governance for the federation

Hardware backed key custody, including YubiHSM, Coldcard, and Securosys support

Trust assumption: at least one honest federation member, or any independent watcher

Variant B · SNARK + BitVM Backstop

The same federation managed peg, backstopped by cryptographic fraud proofs for a stronger trust minimization guarantee

k-of-n federation manages the peg

BitVM fraud proofs stand ready to prevent theft of pegged funds

SNARK verification precedes fund transfer

Trust assumption: at least one honest federation member, or any independent watcher

Choosing a model

Federation + Merge Mine favors operational simplicity and is well suited to teams starting out. SNARK + BitVM Backstop adds a fraud proof layer for teams that want a stronger trust minimization story from day one. Both share the same underlying federation structure, so a deployment can migrate between them over time

Modular Architecture

Each Deployment Is Built From Independent Layers

BitVM Network separates every deployment into four layers. Each layer can be configured independently, which is what allows the same framework to support such different use cases

LayerRoleOptions
Bitcoin L1Settlement and security for the entire deploymentBitcoin mainchain
Peg LayerMoves value between Bitcoin and the sidechainBitVM or federation
ConsensusOrders and finalizes sidechain blocksMerged mining or BFT
ExecutionRuns the application logicEVM, BIP-360, Cosmos, or custom
Application LayerThe product built on topDefined by the team

Because these layers are independent, a change to the execution environment say, moving from EVM to a custom VM doesn't require resecuring the peg or changing how consensus works underneath it

Security Model

Built for Real World Failure Scenarios

Rather than assuming an ideal environment, BitVM Network's security model is built around specific, named failure scenarios and the mechanism that addresses each one.

ScenarioMitigation
Federation collusionStopped by BitVM fraud proofs
51% attacksInherits Bitcoin's hashpower via merged mining
Invalid peg outsAddressed through challenge and slashing
Watcher failureBacked by economic incentives and managed infrastructure
Execution bugsContained within audited execution environments
Double spendEnforced at the Bitcoin UTXO level

Independent verification

This section describes BitVM Network's stated security design for presentation purposes. Stakeholders evaluating a deployment for production or investment use should independently verify the federation's signature threshold and membership, current watcher and fraud proof coverage, and audit status of the execution environment before relying on it for meaningful value

Execution Layers

Any Execution Layer, Bitcoin Pegged

The execution layer is where a team's product actually runs. BitVM Network is designed to secure whichever environment fits the use case, rather than requiring a single VM
