Google just released the first "below-threshold" quantum chip, Willow (with 105 qubits for now). It is the first chip capable of real-time error correction, effectively reducing errors while enabling scalable quantum computing. It’s a strong sign that useful, very large quantum computers can indeed be built.
So what does this mean to modern cryptographic systems and cryptocurrency wallets? How much time do we have before they’re no longer safe?
In this tutorial, we will walk through how to create your own precompile and add it to Geth.
In Geth, precompiles are a set of stateless contracts. But unlike Solidity code, their logic isn't in the smart contract code itself—they are part of the Geth client. You can think of a precompile as an interface that can execute Go code that resides within the Geth client.
The logic for precompiles in Geth is located in the core/vm/contracts.go file.
Here is an example of how to use contracts with different Solidity versions in a Foundry test.
