Blockchain smart contracts explained - Brainbridge IT Staffing

In our article on video games as NFTs and introduction to blockchain technology, we’ve mentioned smart contracts. But what exactly are those smart contracts? And what difference do they make for you? That’s what you’ll find out here.

What are smart contracts?

Smart contracts are layers of code embedded directly on a blockchain that make it easier to execute transactions. They speed up processing times, and simplify agreements usually requiring a third party.

Since blockchain is based on majority consensus, smart contracts are executed when blocks reach a predetermined resolution. Terms become set when the blockchain is created. This process means every change made to a blockchain is executed exactly the same.

A foundation for smart contracts, solidity programming is the language used. In addition, cryptocurrencies like Ethereum store smart contracts directly on its blocks (unlike Bitcoin). This makes NFT smart contract execution fast and straightforward.

To better understand how smart contracts work, it’s useful to dive into the technology behind them. If you’re wondering which crypto has smart contracts, read on to find out.

List of smart contract platforms & tools

Improving the process, there are platforms for developing blockchain agreements that provide different features and benefits. A few of the better known are:

TRON
OpenZeppelin

TRON

TRON smart contract technology includes security features. Based on Ethereum, it’s compatible with other cryptocurrencies like Bitcoin.

With Ethereum topping the list of smart contract platforms, it remains a leader in the blockchain space.

OpenZeppelin

Adding safeguarding, OpenZeppelin contracts utilise an open-source platform to develop decentralised applications (dApps)

OpenZeppelin contracts are databases of smart contracts built on Solidity and Ethereum. They’re also vetted, meaning OpenZeppelin acts as a quality control layer.

Smart contracts developed with OpenZeppelin are useful for:

Controlling access
Defining ownership
Setting parameters
Monitoring token value

Payments & gas fees, like with NFTs.

Which blockchains support smart contracts

In addition to Ethereum, Solana, Polkadot, Ergo, Algorand, and Cardano all have smart contracts as well as value on their blocks.

With Polkadot cited for its interoperability (ability to easily communicate with other blockchains), and Ergo for its unique no gas fee approach, the crypto market is filled with options.

If you’re looking to invest in crypto, and find Bitcoin out of reach, it’s worth considering these. Also, as mentioned before, Bitcoin doesn’t have smart contracts on its blocks. There’s definitely a lot to cover with smart contracts.
