Hire an auditor for blockchain to see your development and work.

Solidity and Ethereum

Solidity is the language most people learn fast as it created the second-largest blockchain Ethereum 🔹.
Solidity is not so difficult if you already know python, java, etc. Yes, it can become a bit strange if you just started in IT.
Solidity is run on Ethereum Blockchain and on every run it consumes transaction fees called gas fees as it is using the blockchain’s hardware(Minors).

Things you need to be aware of before coding

Wallet: This is required to make secure transactions and to maintain records. E.g: MetaMask.
Test networks: The test network is a free network that is used for development and every developer uses it to debug.
Be aware of the network you choose main-net is real Ethereum where real money exists you don’t wanna lose money for debugging right.
ChainLinks: It is the platform we connected to other components or third-party SW to get our data in blockchains. To know here.
