Issue #14: OPOS Hackathon, Switchboard Functions and Solana AI

Only Possible on Solana Hackathon, Switchboard Functions, TAL AI, Encode Sessions, The 76 Devs, and Ironforge Beta

🔨 Only Possible on Solana Hackathon

Back in Issue #10 I mentioned a proposed #OPOS hackathon. Well now it’s actually going to happen thanks to LamportDAO!

The hackathon will kick off on August 1st and runs for three weeks. There will be several tracks including DePIN, Compression, DeFi and sponsors like Phantom, Balaji, and Helium.

I’ll be taking part in this one by adding Token-2022 non-transferable NFTs to my project Vanward!

⚙️ Switchboard Functions

Switchboard Functions allow you to execute your own Rust code off-chain to enable the seamless integration of real-world data into Solana programs, ensuring trust and accuracy in decentralized apps.

A Switchboard Function is executed within its own Trusted Execution Environment (TEE) which provides verification that the code being executed matches the expected measurement authorized by the function's owner.

Functions can be executed as a pre-defined cron job or on-demand for automating tasks on-chain with custom conditional logic.

You can create a Switchboard function with the following steps:

  1. Creating a Switchboard Function

  2. Define Switchboard interface in your program

  3. Write a custom function in Rust

  4. Deploy function to Docker container

  5. Create Switchboard function account

  6. Fund, Lease & Integrate

See Tools & Resources below for a starter template.

🤖 Trustless Autonomous Layer AI

TAL is a “trustless DePIN for on chain AI” model results.

Think of it as the Chainlink of AI. When you request an AI result on TAL, a network of oracles all run the same model, with the same seed and come to a consensus on what your result is.

Programs pay for each AI result generated, and engineers earn royalties each time their model is used.

If you’re interested in building, using, or mining on TAL you can apply here.
