London Bridge

The Secure Bridge Between Algorand and Ethereum

[London Bridge @LondonBridgeApp]

📢 Attention, London Bridge Community!
🚨 The testing period concludes at the end of the month. If you have wrapped tokens, please ensure to unwrap them using our guide before August 31st, when we’ll be shutting down the Testnet servers.
If you encounter any issues or have doubts, please reply in this thread, and our team will guide you through the process.

❓ How does @LondonBridgeApp ensure security and trust in the bridging process?

🎯 London Bridge utilises secure enclaves powered by #IntelSGX. This technology allows us to protect code from modification or interference at runtime, ensuring the integrity of the bridge. We also provide attestation reports from Intel to prove the authenticity of the code running on the enclaves, giving users confidence in the security of the bridge.

❓What sets @LondonBridgeApp apart from other bridges?

🎯London Bridge distinguishes itself by utilizing Intel SGX technology to generate keys and validate the state of the source chain. Unlike most bridges that rely on a network of validators, we leverage secure enclaves to ensure trust and provide attestation reports for code transparency.

While our current focus is on bridging Ethereum and Algorand chains, we are open to exploring opportunities to expand London Bridge to bridge to other blockchain networks in the future. We are continuously evaluating the needs of the community and working closely with the foundation to determine the best path forward.

Welcome to TestNet, @LondonBridgeApp!

[Algorand Foundation @AlgoFoundation]

We're thrilled to host @AndyAppBlock and @SelvaggiaDF from @AppBlockchain on a #Reddit AMA next week to dive deep on the tech of the @LondonBridgeApp.

🗓️ Mark your calendars for Tuesday, July 4th

[London Bridge @LondonBridgeApp]

@AmsonSoft Thanks for testing! You can do, up to you where you want the tokens. If you want your original UNI back on Goerli you can bridge back.

If you want to test stateproof these get used when you go from Algorand -> Ethereum

📢 Exciting News! London Bridge is Live on Testnets! 🚀

Are you ready to embark on an extraordinary journey with London Bridge? The long-awaited moment has finally arrived! We are now live on testnets: https://t.co/br5MZak9Yq
Unsure sure how to test? We’ve put together a comprehensive testing guide on “How to use the London Bridge Web App”: https://t.co/KEVc1zN2gw

Stay tuned for more updates and announcements and follow us on our social media channels to ensure you don’t miss out on any important information.

It would be more cumbersome and enclaves like to only have small amounts of code, stateproofs allow us to achieve the same outcome of validating the chain without needing to hold the entire state. The only downside is we need to wait for the next proof before accepting a txn which takes a while sometimes

[London Bridge @LondonBridgeApp]

If you have any question on what makes London Bridge different please tweet us!

We want to make sure everyone understands how the bridge works and the trust assumptions #Algorand #algofam #ALGO #Ethererum

[London Bridge @LondonBridgeApp]

@pedromeves Developing light clients in enclaves is really tough.

Would need to ask the dev team directly probably:
1. Figuring out the state proof validation and getting this running in SGX
2. After we got the PoW light client working on ETH changing this over to ETH 2.0 PoS

[London Bridge @LondonBridgeApp]

@HMD2V The second one, we rely on the secure enclave to validate the state of the chain and sign on chain.

The reasons for this approach can be seen here: https://t.co/lX24QbO86f

[London Bridge @LondonBridgeApp]

@DragonFi_Realm @AlgoNautilus The problems with validating state proofs directly in a contract (solidity in this case) are:
1. The complexity of the validation logic leading to an unmanageable gas fee
2. The need for a solution in the other direction ETH -> Algo

But we will keep an eye on these assumptions

@vegycslol @AlgoFamily @chrisswenor @lobo55399880 But the enclave public keys are kept in a smart contract and validated there, so the upgrade process must always be public. We have no backdoor for doing upgrades in private.

[London Bridge @LondonBridgeApp]

@vegycslol @AlgoFamily @chrisswenor @lobo55399880 We will have upgrades. We are working on the governance process for this. The governance process does not need to be controlled by hotkeys which we view as the main risk in bridges. Can be a multisig or contract based, whatever is appropriate for the amount of funds secured.

[London Bridge @LondonBridgeApp]

@vegycslol @AlgoFamily @chrisswenor @lobo55399880 More on the why here:
https://t.co/lX24QbNAgH

You'll be able to audit our code running on SGX along with a signed attestation from Intel of the code and the bridging key generation.

Our opinions on SGX and why we think it add piece of mind are here:

[Andy Campbell @AppBlockchain @AndyAppBlock]

There have been some really great questions on London Bridge covering both depth and breadth.

One thing that we haven't gone in depth on yet is potential vulnerabilities with SGX… (1/6)
