The demand for these blockchain skills raised by 552% in 2022, as per an IT report.
The report, which provides annual assessments of digital and IT skill trends, also revealed the specific blockchain skill sets that are most in demand: Solidity , Hardhat , Smart Contracts , Truffle , and Chainlink .Solidity - 44%
Solidity was specifically created for the implementation of smart contracts on private blockchain platforms, such as Ethereum, but it is also used in the open-source proof-of-stake blockchains like Avalanche and TRON , as well as in Binance Smart Chain and peer-to-peer Bitcoin-based financial platform Counterparty.In fact, Solidity employs a syntax similar to Javacript’s standard ECMA Script, which means that current web developers should find it relatively easy to learn.
The network helps them find issues with their smart contracts, such as failed calls or failed transactions, and supplies them with JavaScript and Solidity stack traces to help them pick out the reasons for the failure if the network can’t identify them by itself.A smart contract is a computer program that contains the terms of an agreement or a transaction between two parties within its code. They run on blockchain networks and are verified automatically.
For example, if a smart contract states that funds in escrow will not be released until after work is delivered, the contract will “wait” for proof of work delivery to send the funds to the other party. And it will do this automatically.Smart contracts were first proposed by American computer scientist and cryptographer Nick Szabo in 1994.
Truffle allows developers to compile, link, deploy, and conduct automated tests on their smart contracts in both JavaScript and Solidity languages before they are launched in the real blockchain network. The platform uses the Ethereum Virtual Machine , part of the Ethereum blockchain’s ecosystem. Chainlink enables these contracts to automate the transfer of data between the blockchain and external systems. This way, it allows smart contracts to interact with real-world data and services so that they can determine if they must self-execute or not.
