"What's needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party." — Satoshi Nakamoto

These words from Satoshi Nakamoto lit the fuse for everything that followed. Today, that same spark powers our work.

Not just as a tribute — but as a foundation for something new.

Inspired by Bitcoin’s original vision. Built for TON. TON Teleport BTC lets you move BTC to TON without intermediaries, wrapped assets, or permissioned bridges. Just smart contracts and math. Every step is enforced by code and cryptographic proof.

Let’s break down how it works, why it matters, and what makes it different from everything that came before.

Peg-in: Getting BTC to TON

Step 1: Send BTC. Get tgBTC on TON. From the outside? Dead simple. Send BTC to an address. Wait a bit. Get tgBTC on TON.

But under the hood? Pure blockchain wizardry.

Enter the Light Client. It’s a full-on Bitcoin light client built inside TON. Written in FunC. It syncs block headers, checks PoW, parses transactions, and keeps track of everything. It’s not a watcher — it’s a validator.

Anyone can submit Bitcoin blocks. No gatekeepers. No centralized APIs. If the block’s fake? Rejected instantly.

Once a block is verified, you push your BTC transaction. Teleport checks if it’s really there, reads it byte by byte, and if everything’s tight — it mints tgBTC.

Basically a Bitcoin node, reassembled from scratch, without the network stack. Just cryptography and sheer will.

Peg-out: Getting BTC back

Step 2: Burn tgBTC. Get BTC back. Burn your tgBTC. Enter a Bitcoin address. Done, right?

Not quite.

Bitcoin doesn’t support smart contracts or light clients. So to unlock BTC, we need a different move.

Enter the Validators. TON validators step in — but not as judges. All they do is sign the BTC transaction that Teleport has already built, based on verified on-chain data.

No oracles. No "committee of trust." Just the existing TON consensus, stretched to do something new.

Teleport bends the rules without breaking trust.

Cryptography That Powers It

TON Teleport BTC uses modern cryptographic tools like DKG (Distributed Key Generation) and FROST (Flexible Round-Optimized Schnorr Threshold Signatures).

• DKG allows validators to generate a key together without anyone holding the full key.
• FROST merges validator signatures into one clean line. Saves Bitcoin fees. Keeps decentralization sharp.

Keys rotate. Validators rotate. No one sticks around long enough to be dangerous.

Is It Really Trustless?

Some people might say:

"Wait, validators sign the transaction — isn’t that custodial?"

Yeah, we hear that a lot. But here’s the deal:

Every chain you love relies on consensus. Bitcoin has miners. Ethereum has validators. Same for TON.

TON Teleport BTC doesn’t add a new trust layer — it uses the one already baked in.

No new signers. No off-chain whispers. Just deterministic logic on-chain.

Uniswap is trustless until Ethereum decides it isn’t. Same energy.
