WebIt's basically a privileged contract that has the right to trigger messages from another chain. It's a pretty standard thing for cross-chain projects. There's this function verifyHeaderAndExecuteTx that anyone can call to execute a cross-chain transaction. Basically it (1) verifies that the block header is correct by checking signatures (seems ...

WebDec 14, 2024 · When understanding the difference between storage and memory, you can think of storage as a kind of hard disk in the traditional computing world, in the sense that it has “persistent” storage of data. But memory is closer to RAM in traditional computing. The stack is the data area where most of the EVM’s computations are performed.
WebIn summary, memory and calldata are both temporary data storage locations in Solidity, but they have important differences. Memory is used to hold temporary variables during function execution, while Calldata is used to hold function arguments passed in from an external caller. Calldata is read-only and cannot be modified by the function, while ... WebAug 12, 2024 · calldata vs memory.

WebDec 6, 2024 · In short, use calldata instead of memory if the function argument is only read. Note that in older Solidity versions, changing some function arguments from memory to calldata may cause “unimplemented feature error”. This can be avoided by using a newer ( 0.8.*) Solidity compiler.
