Austin (00:10):

All right. Welcome guys. We're here to talk today about the transfer layer, scalability, cross chain bridging, the technical problems, the operational problem, the UX problems. This is just a panel of problems today, but it's also a panel on opportunities. We've seen a huge amount bridge over between other protocols in solana between other protocols and other protocols. We think of bridges as something new, but bridges are how DeFi has used Bitcoin as collateral for quite a long time at this point. It's kind of funny to think about how this started as we're taking an asset that's considered quite stable and solid that has no smart contract ability and being able to use that in Ethereum and that early day work really set the stage for, I think, a lot of what we're seeing today.

Austin (00:55):

But bridges go far beyond just this idea of how do I move something from chain A to chain B. There's roles in them as being decentralized ways to pass messages between different chains. There's a role for them in making users feel safe about trading across chains, and there's a role about them, about creating an exit ramp too. So that if you do something like buy an NFT for $69 million, you're not dependent on one chain to hold that. There's an ability migrate in a decentralized and trustless way. So we're getting into a bunch of that today. I'd say, let's just go ahead down the line and give a quick introduce to yourself and your project.

Hendrik (01:31):

Sure. I'm Hendrick. I'm with Jump Crypto and as Jump Crypto we're core contributors to Wormhole, which is a cross chain messaging protocol, connecting high value chains. And message passing in this sense means anything can flow between these high value chains, meaning assets and data. So your coins, NFTs, but also governance decisions and more information like as a base layer for developers to build on top of.

Bryan (01:54):

Bryan from LayerZero. Our focus is purely generic messaging interop. High level is connect every contract on every chain to every contract on every other chain.

Alex (02:05):

Hi everyone. My name is Alex Smirnoff and I'm co-founder of the deBridge Protocol, which is cross chain interoperability and liquidity transfer protocol. So the protocol itself allows to breach any arbitrary assets or data between any blockchains including solana of course, down the road.

Andriy (02:23):

Hi I'm Andriy from Allbridge, I'm a co-founder there. We currently support seven blockchains, and I hope that this number would increase to 12 by the end of the year. We started in July and since July, we bridged to solana one point half billion worth of assets.

Austin (02:44):

It's great to see. So I want to start out with just a level set question and Andriy, we'll start with you. Why is it important for a bridge to not rely on trust?

Andriy (02:54):

You see, when we speak about trusted bridges and trustless bridges, and that is the question, I suppose?

Austin (03:00):

Yes.

Andriy (03:01):

We have to consider that while we all here are building decentralized future, which should be completely trustless, in my personal opinion, sometimes we may sacrifice some layer of some level of decentralization to provide faster and better user experience. Because we are, in the end of the day, we are limited by the technology. And I have been thinking a lot about that because in the very end, we are building for our users and we want to create the product that would be used and used easily. And when we, in some cases, add too much of decentralization, that...
