SatoshiVM is a versatile ZK rollup that uses EVM for off-chain computations. This means that users can interact with SatoshiVM in a similar way to how they interact with Ethereum, and developers can build on top of SatoshiVM just like they would on Ethereum.

What is SatoshiVM?
SatoshiVM bridges the EVM ecosystem with Bitcoin, enabling the Bitcoin ecosystem to issue assets and develop applications.
Features
- ZK EVM: It is a versatile ZK Rollup that uses EVM for off-chain computations.
- ZK Rollup: SatoshiVM uses Rollup technology to batch multiple transactions together and verify them as a single transaction on the Bitcoin mainnet.
- ZK Fraud Proofs: SatoshiVM uses technologies like Taproot and Bitcoin Script to perform on-chain verification of contracts without changing the consensus rules of the Bitcoin network, thereby enabling the calculation of fraud proofs.
- Data Availability: SatoshiVM must publish transaction data on the Bitcoin mainnet and ensure that anyone can verify the correctness of computations that are executed outside of the Bitcoin mainnet.
- Native BTC Gas: SatoshiVM uses native BTC as gas for EVM. Similar to ETH OP Rollup/ZK Rollup Layer 2 solutions that use ETH as gas for Layer 2, SatoshiVM uses BTC as gas for EVM transactions.
How does it work?
SatoshiVM works by passing through 3 distinct phases, identifying each with a different layer name.
Settlement Layer
It provides chain-for-data availability, sequencing, and proof verification. It allows users and dApps to send messages and assets between Bitcoin and SatoshiVM. Bitcoin serves as the payment layer, and bridges and aggregation scripts are deployed on the Bitcoin network.
Sequencing Layer
It consists of an execution node responsible for executing transactions sent to the sequencer and transactions sent to the L1 bridge script that produces L2 blocks. It also includes an Aggregation node that manages batched transactions, publishes transaction data and block information to Bitcoin to ensure data availability, and sends validity proofs to Bitcoin for finality.
Proof-of-Layer
It consists of a coordinator that assigns proof tasks to provers and transmits the generated proofs to the Aggregation node to complete finality verification on Bitcoin. It also includes a proof pool responsible for producing validity proofs that verify the correctness of L2 transactions.
From Bitcoin Network to SatoshiVM Network
Transactions made from Bitcoin (L1) to the SatoshiVM mainnet (L2), even if they contain no additional assets, are referred to as deposits.
Deposit transactions become part of the blockchain of the first L2 block of a “epoch” corresponding to the L1 block in which the deposit transaction took place. This L2 block is typically created a few minutes after the corresponding L1 block.
