# A One Way Bridge

Nov 17, 2024

Okay I went to Devcon. And while there I had a great idea that the crypto space really needs. It seems like while AI infrastructure has improved by leaps and bounds in the last 5 years, crypto infra has actually gotten worse. I’m proposing some great new infrastructure that the crypto space deserves.

We still don’t have a good decentralized bridge between Bitcoin and Ethereum, and with the rising price of Bitcoin this is more important than ever. I have some experience building bridges, so I’m proposing one. However, unlike most bridges, this is a one way bridge. It works like this:

1. Send Bitcoin to 3bridgebridgebridgebridgebridge
2. Wait for several block confirmations
3. Prove inclusion of your send in the Bitcoin chain to the bridge
4. Receive BBTC (Bridged BTC) tokens on Ethereum of the amount sent

I’ll note, nobody has the private key to 3bridgebridgebridgebridgebridge, so there is no way to recover your original Bitcoin. That’s okay, they have been safely bridged to Ethereum and you have received your BBTC token.

If you’d just like to buy exposure to Bitcoin on Ethereum without using the bridge, you can buy the BBTC token on any DEX.

Is it really that simple? Answer: yes, but only if people believe it is.

You can’t really believe the BBTC token is worth 0, can you?
