# Why LitVM?

MidasPredict is built natively on LitVM — the first fully trustless, EVM-compatible Layer-2 rollup for Litecoin. If you've used other L2s like Arbitrum or Base, the experience is similar: fast trades, low gas, and assets secured by a proof-of-work chain.

## Architecture

LitVM employs a hybrid optimistic + zero-knowledge rollup design:

* **Execution:** Arbitrum Nitro stack — battle-tested, EVM-compatible, high throughput
* **ZK validity proofs:** Succinct zkVM — cryptographic proofs for ZK-grade economic finality
* **Sequencing:** Espresso decentralized sequencer — sub-100ms pre-confirmations, no single point of failure
* **Bridging:** BitcoinOS / Charms — trustless, non-custodial bridge for LTC and Litecoin-native assets

## What It Means for You

### Sub-Second Pre-Confirmations

The Espresso sequencer provides sub-100ms pre-confirmations. Daily Markets and high-frequency trading work smoothly.

### Sub-Cent Gas Fees

Small, frequent trades don't get eaten by gas. Micro-bets are viable. Points earnings aren't offset by fees.

### EVM Compatibility

LitVM is fully EVM-compatible. MetaMask, Solidity contracts, and the entire Ethereum tooling ecosystem work out of the box.

### Litecoin Settlement Security

At maturity, LitVM settles to Litecoin L1, inheriting Litecoin's proof-of-work consensus security. MidasPredict's market resolutions ultimately anchor to one of the oldest and most decentralized blockchain networks.

<details>

<summary>What if LitVM goes down?</summary>

MidasPredict would be temporarily unavailable. Contracts are EVM-compatible and theoretically portable to alternative L2s.
