💡Key Ideas:

• In general, coprocessors enhance the capabilities of the main processing unit (thing of GPUs to CPUs)
• In blockchain context, coprocessors enhance the things you can do in a blockchain.
• ZK coprocessors enables to prove facts about a blockchain with offchain computation.
• What's the problem it's trying to solve? Smart contracts can only access the current state of a blockchain, not past states.
• ZK coprocessors are ZK Infrastructure that allows smart contract developers to prove off chain computations about onchain data.

For example:

• What was the average of ETH/USDC price during last month?

• How much ETH does X account had on 1st of Jan of last year?

• Demonstrate a succesful degen trade I did in the past

• Prove that I had X amount of tokens in the past.

🛠️ Build and Practice:

Create a small app that calculates the average price of ETH/USDC during a past trailing month using zk coprocessors (not oracles)
