Overview

Mythic is a Solana Virtual Machine (SVM) Layer 2 blockchain built on the Firedancer runtime. It is designed from the ground up to serve as infrastructure for AI-native decentralized computing, combining the speed and composability of Solana with purpose-built AI consensus and a decentralized compute marketplace.

Unlike general-purpose Layer 2 networks, Mythic introduces Proof of Useful AI Work (PoUAIW) as its consensus mechanism. Validators do not simply attest to block validity -- they earn $MYTH by performing real AI inference tasks that contribute to the network. This means every block produced on Mythic advances both the blockchain and the AI compute available to users.

Key Features

• 1M+ TPS peak capacity via Firedancer networking stack (scales with network load and validators)
• 400ms block times for near-instant confirmation
• Full Solana program compatibility (deploy existing Solana programs without modification)
• AI-native precompiles for inference, model verification, and logit validation
• Decentralized compute marketplace for GPU, CPU, and storage
• Native bridge to Solana L1 with optimistic fraud proofs
• $MYTH as native L2 gas currency with deflationary burn on every transaction

Architecture

Mythic L2 uses a modular architecture that separates transaction ordering, execution, verification, and settlement into distinct layers. This allows each component to be optimized independently while maintaining security guarantees through Solana L1 settlement.

Transaction Lifecycle

Data Availability

Transaction data is posted to Solana L1 in compressed form. The Mythic sequencer uses erasure coding to ensure data availability even if some L1 slots are missed. Full nodes can reconstruct the entire L2 state from L1 data alone.

Fraud Proofs

Mythic uses an optimistic rollup model. State transitions are assumed valid unless challenged within a 7-day window. Any node can submit a fraud proof to the L1 settlement contract, proving that a specific state transition was invalid. Successful challengers are rewarded from the sequencer's bond.

$MYTH Token

$MYTH is the native currency of the Mythic L2 blockchain — similar to how ETH is native to Ethereum. It is minted at genesis with a fixed supply of 1,000,000,000 tokens, 9 decimal places, and zero inflation. Every transaction on Mythic L2 pays gas fees in $MYTH, and a portion of each fee is permanently burned.

Token Details

Token Utility

• Gas fees — every transaction on Mythic L2 is paid in native $MYTH
• Validator staking — validators stake $MYTH to participate in block production
• AI compute payments — pay for inference and model verification in $MYTH
• Governance voting — stake-weighted governance proposals and votes
• Compute marketplace — settlement currency for GPU/CPU/storage listings

Fee Distribution

All fees on Mythic L2 are paid in native $MYTH. Each fee type distributes across three destinations: validators (who run the network), the foundation (which funds development), and the burn address (removing tokens from circulation permanently).

Staking

Validators must stake a minimum amount of native $MYTH to participate in block production and AI verification. Staked $MYTH earns rewards from transaction fees. The staking APY is dynamic, based on the total amount staked and network activity.

Bridge

The Mythic Bridge is the core infrastructure that connects Solana L1 and Mythic L2. It enables users to move assets between the two chains. Deposited assets are credited as their L2 equivalents, with native SOL becoming MYTH on L2. The bridge uses an optimistic rollup model with fraud proofs, secured by Solana L1 settlement.

Architecture Overview

The bridge consists of two on-chain programs (one on Solana L1, one on Mythic L2), a relayer service that watches for cross-chain events, and a settlement service that posts Merkle state roots to L1 for verification.

Deposits move assets from Solana L1 to Mythic L2. Native SOL is credited as MYTH on L2. The process is fast -- typically confirmed within ~30 seconds.

Withdrawals move assets from Mythic L2 back to Solana L1. Because Mythic uses an optimistic rollup model, withdrawals include a 7-day challenge period to allow fraud proof submission before funds are released.

These are the on-chain program addresses for the Mythic bridge infrastructure. Verify these addresses before interacting with the bridge.

Token-2022 compatible asset bridging is planned for a future upgrade, enabling additional tokens to be bridged between L1 and L2.

There are multiple ways to bridge assets between Solana L1 and Mythic L2:

The Mythic Bridge is secured by multiple layers of protection, combining the security of Solana L1 settlement with optimistic fraud proofs and operational safeguards.

• Optimistic rollup model -- state transitions are assumed valid unless challenged within the 7-day window
• Settlement roots posted to Solana L1 every 100 slots, verifiable by anyone
• Any honest observer can submit a fraud proof to the L1 settlement contract
• Successful fraud proof challengers are rewarded from the sequencer bond
• Emergency pause mechanism allows the bridge admin to halt operations instantly
• Bridge admin authority will be transferred to a multisig/Ledger hardware wallet before mainnet launch
• Daily withdrawal limit of 10,000 MYTH caps exposure in case of exploit

Bridge operations incur a 10 basis point (0.1%) fee on deposits. This fee is distributed through the standard MYTH fee allocation model, contributing to network security and deflationary pressure.

Bridge fees contribute to the deflationary pressure on $MYTH. With 40% of each bridge fee burned, increased bridge usage directly reduces the circulating supply.

AI Precompiles

Mythic L2 includes native AI precompiles -- system-level programs that provide AI inference and verification capabilities directly in the execution layer. These are available to any Solana program running on Mythic.

RunInference

Execute AI model inference on-chain. Submit input data and a model identifier, and receive the model output as part of the transaction result.

// RunInference precompile
// Program ID: MythAI1111111111111111111111111111111111111

Instruction Data:
  - model_id: [32 bytes]     // Registered model identifier
  - input_data: [variable]   // Model input (tokenized)
  - max_tokens: u32          // Maximum output tokens
  - temperature: f32         // Sampling temperature

Returns:
  - output_data: [variable]  // Model output
  - confidence: f32          // Output confidence score

Returns:
  - valid: bool              // Whether output matches
  - divergence: f32          // KL divergence from expected

RegisterModel

Register a new AI model on the Mythic network. Models must be registered before they can be used with RunInference.

// Program ID: MythAI3333333333333333333333333333333333333

Instruction Data:
  - model_hash: [32 bytes]   // SHA-256 of model weights
  - model_uri: String        // IPFS or Arweave URI
  - model_type: enum         // LLM, Vision, Audio, etc.
  - min_stake: u64           // Min validator stake to serve

Returns:
  - model_id: [32 bytes]     // Assigned model identifier
  - registered_at: i64       // Timestamp

Compute Marketplace

The Mythic Compute Marketplace is a decentralized marketplace for GPU, CPU, and storage resources. Providers register their hardware and set pricing; consumers rent compute by paying $MYTH.

For Providers

Anyone with spare compute capacity can register as a provider. The registration process involves staking $MYTH and submitting a hardware attestation.

For Consumers

Request compute resources by specifying requirements (GPU type, VRAM, duration) and a maximum price. The marketplace matches you with the best available provider.

Pricing Comparison

Validators

Mythic validators are the backbone of the network. They produce blocks, validate AI inference results, and maintain the state of the L2 chain. In return, they earn $MYTH from transaction fees.

Requirements

Validator Tiers

Validator Setup (Firedancer)

Mythic L2 runs on Firedancer (fdctl), the high-performance Solana validator client by Jump Crypto. Follow these steps to join the network.

# 1. Install Firedancer
git clone https://github.com/firedancer-io/firedancer.git
cd firedancer
./deps.sh
make -j fdctl

# 2. Generate validator identity
solana-keygen new -o identity.json

# 3. Create config (mythic-validator.toml)
cat > mythic-validator.toml << 'EOF'
[gossip]
  entrypoints = ["rpc.mythic.fm:8001"]
[rpc]
  port = 8899
  transaction_history = true
[consensus]
  identity_path = "identity.json"
  expected_genesis_hash = "<genesis-hash>"
EOF

# 4. Start the validator
sudo fdctl run --config mythic-validator.toml

# 5. Register as a validator on-chain
node scripts/register-sequencer-validator.mjs --execute --server

CLI Commands

# Check validator status
solana -u https://rpc.mythic.fm validators

# View your validator's fee account
solana -u https://rpc.mythic.fm account <VALIDATOR_PDA>

# Check network slot
solana -u https://rpc.mythic.fm slot

# View epoch info
solana -u https://rpc.mythic.fm epoch-info

Rewards

Validators earn rewards from two sources: transaction fee distribution (50% of all fees go to validators) and AI compute payments (for serving inference requests). AI-capable validators receive a 2x reward multiplier. Rewards are distributed automatically every epoch (~1000 slots) by the reward distributor crank.

Roadmap

Mythic development is organized into four major phases, from initial network launch to full AI compute decentralization.

Foundation and Governance

The Mythic protocol is stewarded by Mythic Foundation, a Wyoming Decentralized Unincorporated Nonprofit Association (DUNA), formed under Wyoming Statutes 17-36-101 through 17-36-115. The DUNA structure was purpose-built by Wyoming to give decentralized autonomous organizations a formal legal personality — enabling the Foundation to hold assets, enter contracts, and represent the interests of $MYTH token holders without requiring a centralized governing board.

Wyoming DUNA

Wyoming's Decentralized Unincorporated Nonprofit Association Act (W.S. 17-36-101 to 17-36-115) is the first U.S. legal framework designed specifically for DAOs. Key provisions that apply to Mythic Foundation:

• Legal personhood — the DUNA can sue, be sued, hold property, and sign contracts in its own name.
• Member-managed — governance is exercised directly by $MYTH token holders through on-chain voting; no board of directors is required.
• Limited liability — members and participants are not personally liable for DUNA obligations solely by reason of their membership or token holdings.
• Non-profit purpose — the DUNA exists to promote the Mythic protocol, fund ecosystem development, and advance open, decentralized AI infrastructure; it does not distribute profits to members.
• Smart-contract governance — the DUNA governing documents may delegate decision-making to on-chain smart contracts (the Mythic Governance program).

Governing Principles

The following principles govern Mythic Foundation's activities and cannot be amended without a supermajority on-chain vote (≥ 67% of staked $MYTH):

DAO Structure

The Foundation's on-chain governance is powered by the Mythic Governance program (deployed at MythGov111111111111111111111111111111111111 on Mythic L2). Proposals follow a structured lifecycle:
