Hello everyone,
Can anyone tell me, how to identify that a transaction is cancelled or dropped, in the ethereum blockchain?

Thanks in advance

@hooji
When you submit the transaction to the client you will receive a transaction hash back. You can look on the bockchain to see if that transaction has been incorporated or not. Even if it has not been incorporated yet, it's possible that the transaction is still outstanding and may be incorporated in the future (the transaction could be delayed because you set the gas price to a low value). If you want to 'cancel' the transaction to make sure it never goes through you must issue a new transaction (with the same nonce) which does get executed. Once the new transaction has been incorporated then the old transaction is no longer valid (because the nonce is wrong).

In solidity, A 'pure' function can neither modify the contract's data nor read it. Can you give example of a function that might need to be 'pure' ?

Hey guys. I recently wrote an article which explains you step by step how you can build a full stack vending machine ethereum dapp with solidity and javascript. Maybe someone in this group might be interested!

Here is the tutorial: https://www.roheat.com/code-a-full-stack-vending-machine-ethereum-dapp-with-solidity-and-javascript/

Please feel free to check it out and leave some feedback. Thanks!

Didn't find a lot of resources on how to deploy a gas free Parity PoA chain into a Kubernetes environment. I tried to keep this sample project as basic and simple as I can. Hoping it can help other people that want to play around with a gas free chain in a kubernetes environment!
