Self-sovereign by design. Every node runs a real Bitcoin node. Every block anchors to Bitcoin. Quantum-resistant from genesis.
Every node runs a real Bitcoin node. Every block anchors to Bitcoin via Taproot. Post-quantum identity, verifiable credentials, on-device AI, and six ways to earn on consumer hardware.
Own your identity. Local AI. @toshi.btc identity. Earn with optional BitAxe USB miner.
Bitcoin payments. Verifiable credentials. Creator OS. No cloud fees.
102K Rust. EVM translation. X402 payments. Five UTXO lanes.
EVM contracts translate in. Synthetics lane for any asset. Settled on Bitcoin.
Download Toshi Wallet or Toshi Browser and you are running a full node. Bitcoin Core or Knots validates real BTC transactions. ProofnetTM runs consensus. BTCoreTM routes services. ElliottTM AI indexes knowledge. The mesh connects. Verified-work features can be enabled as the network rolls out. The user sees a wallet. The network sees a full participant.
GitHub without GitHub. Every node runs an integrated Gitea instance. Commits are PQ-signed with ML-DSA-65 keys. Repos replicate across the mesh via gossip protocol. Access via .btc domains over PQTLSTM. Every code change produces a cryptographic attestation with before/after SHA3-512 hashes committable to Memory BlocksTM. Your code, your node, your keys. No corporation can revoke your access or take down your repo.
Bitcoin answered whether people can coordinate around money without institutions. The next question is whether they can coordinate around an entire economy.
This network argues yes — through receipts, memory, and settlement on Bitcoin.
Scale is not just about how many transactions the network can process. It is about how much the network learns. A network that processes a million transactions and learns nothing has scaled horizontally. A network that processes a million transactions and accumulates a million verified, trust-scored knowledge artifacts has scaled in a dimension that no other blockchain occupies.
Design Milestones
These nine design milestones capture the architecture that makes BAN distinct. Built from the ground up in Rust. Built in Logan, Utah.
NIST FIPS 204 post-quantum signatures at the consensus level, from block #1.
Toshi PQ1TM: on-device ML-DSA-65 key generation. The secret key is designed to stay on the chip.
Finalized Memory BlocksTM feed verified local knowledge indexes and supervised datasets for local models.
Milliseconds, 90 seconds, or 5+ minutes on the same chain, under one security model.
PQTLSTM: no certificate authority dependency. Node identity serves as the certificate.
STT, TTS, and voice cloning on consumer CPU with permissively licensed components.
AttestoScriptTM with live EVM/Solidity translation, bounded execution, and no general-purpose VM.
Mine, validate, store, train AI, build models, and anchor Bitcoin on consumer hardware as programs are enabled.
The chain provides verified context to the AI, and the AI can write receipts back to the chain.
Built on Bitcoin
Bitcoin is sound money. The most secure, decentralized, battle-tested financial network ever created. The Bitcoin Attestation Network does not change Bitcoin's consensus rules. Every ProofnetTM node runs a real Bitcoin node. Every Memory BlockTM anchors to Bitcoin via Taproot. We extended Bitcoin into identity, credentials, AI, and programmable finance. All settled on Bitcoin.
BAN nodes embed a real Bitcoin node. Choose Bitcoin Core, Bitcoin Knots, or any compatible implementation. Your machine validates both chains.
BAN is designed for a 1:1 Bitcoin vault lane via Taproot. Public deposits remain disabled unless and until legal and technical readiness is complete.
BitAxe USB miners can contribute SHA-256 work that strengthens Bitcoin and may qualify for qBTCTM Anchor Shares on BAN when that program is enabled. Both networks benefit from the same work.
EVM compatibility brings Ethereum dApps and real-world assets into the Bitcoin economy via AttestoScriptTM. Nobody gets left behind.
Speed
How long until your transaction is permanent?
Other chains force one speed for everyone. BAN lets each transaction choose its own finality level - fast for coffee, medium for transfers, deep for real estate. Same chain, same security model, different speeds.
Attestor preconfirmation. Millisecond settlement for payments and credentials. Buy coffee. Verify an ID. Done.
2/3+1 finality checkpoint. Under 90 seconds. Permanent and irreversible. Online purchases. Fund transfers. Settled.
Stacked checkpoints. 5+ minutes. Maximum security for institutional settlement. Real estate. Vaults. High-value contracts.
AI Innovation
ElliottTM is fine-tuned from supervised datasets built from finalized attestos and Memory BlocksTM, not internet scrapes.
A local knowledge index that compounds with every block. The deeper the chain confirms a fact, the more the AI trusts it.
Your prompts, data, and model weights stay on your machine by default. Connect any provider you choose.
AI Cognition Shares and Model Build Shares are designed to reward verified inference and training work when those programs are enabled.
Self-Sovereignty
In Bitcoin, running a full node is a volunteer act. You validate the chain, strengthen the network, and store the ledger. BAN is designed to reward verified network work performed by node operators when those features are enabled.
Run a node on your own hardware. No cloud. No custodian. No permission. Your ML-DSA-65 keys live on your device or your Toshi PQ1TM hardware wallet. Multiple verified-work paths can run from the same machine as rollout expands.
Get yourname@toshi.btc. Resolve .btc domains through peer attestation, not DNS. No ICANN, no registrar, no corporate gatekeeper. Your node IS your identity provider. Carry verifiable credentials on your phone.
ElliottTM AI runs on your hardware, grounded in datasets and local knowledge indexes derived from finalized attestos and Memory Blocks. Your data stays local by default. You choose what to share, what to train on, and what provider to connect. You own the model weights.
If you run a Bitcoin full node today, you already have the hardware and the conviction. The Bitcoin Attestation Network lets you run both nodes on the same machine. Your Bitcoin node validates BTC. Your BAN node validates Memory BlocksTM, records attestations, and anchors every block back to Bitcoin. When verified-work programs are enabled, the same machine can qualify for qBTCTM work shares.
Every credential, transaction, AI model, and identity proof on the network is signed with post-quantum keys that you control. No corporation can freeze your account, revoke your credentials, or harvest your data. The entire economic stack is self-sovereign. This is what "be your own bank" looks like when you extend it to identity, credentials, and AI.

Build websites, stores, and docs from your node. AI assistance on every page. Publish through the network instead of relying on ad platforms.
Why It Matters
Finalized blocks feed supervised training datasets. The AI fine-tunes locally via LoRA, reasons over verified knowledge, and writes new attestations back. The network accumulates intelligence with every block, not just length.
No pre-mine. No token sale. No VC allocation. No staking yield. The economic model is based on verified work instead of passive return. Consumer hardware keeps participation accessible while Bitcoin remains the reserve layer.
BAN keeps AI outputs outside consensus validity. AI can help produce attestations, but chain validity does not depend on model responses. That separation keeps model failures from becoming chain failures.
Not just transactions. Not just state. Transactions + credentials + identity + AI training data in one Merkle-rooted, PQ-signed, Bitcoin-anchored container. That is a new data structure. Everything else in the system derives from getting that one structure right. When you understand Memory BlocksTM, the rest of the network stops looking like unrelated features and starts looking like one coherent economy.
102,691 lines of consensus engine. Memory-safe, no garbage collector, no buffer overflows, no use-after-free. Starting from zero in Rust was the expensive choice. It materially reduces several bug classes that have caused costly failures in lower-level and VM-based stacks.
Every node runs real Bitcoin. Every block anchors to Bitcoin. The 21M cap mirrors Bitcoin. Same UTXO model. Same proof of work. This is not "Bitcoin killer" positioning. It is Bitcoin economy positioning built around Bitcoin as the reserve layer and BAN as the operating layer.

After federal funding was cut, a public administrator with a background in emerging technologies and cybersecurity built 710,000 lines of post-quantum infrastructure from an apartment in Utah.
