There are no rewards for running a node. StarkNet is still centralized - this means there is no consensus mechanism and therefore no way to earn rewards.



Are there rewards for running a Pathfinder node?

 I was able to run those commands without setting up a StarkNet account

When you run warp deploy or warp invoke, which account is paying for the tx fees on the Goerli testnet?

Just saw this in Cairo v0.10 docs: "support using functions as expressions"
Can anyone explain how does that work exactly? any example would be very helpful
It's mentioned here: https://github.com/starkware-libs/cairo-lang/releases/tag/v0.10.0#:~:text=Support%20using%20functions%20as%20expressions

Can you explain Cairo v0.10 usage functions as expressions?

Hey! The title sort of summarizes the question. I was wondering if there's any project where I can see an example of how something like `keccak256(abi.encodePacked(var1, var2, var3))`  could be achieved in starknet.

If there were a way to concatenate bytes, I think it wouldn't be too complicated, but such a string would never fit in a felt, and using a struct won't result in the same output.

So yes, my question is if there's an equivalent way to achieve this behavior in cairo.

Equivalent to Solidity's keccak256(abi.encodePacked())?

I got an error while deploying:
`{"code": "StarknetErrorCode.DEPRECATED_TRANSACTION", "message": "Deploy transaction is no longer supported."}`

Umm, cairo playground does not support deploying contracts anymore

What is the most user-friendly way to deploy contracts on starknet for now?
