How to Build DApp and smart contracts on aeternity blockchain ?

What is Aeternity ?

Aeternity is a blockchain network which allows for hosting smart contracts and dapp developments off the main network that makes it runs faster. Aeternity blockchain runs faster and seems to be more energy efficient than competing blockchains. It mainly deals with the scalability and offering extra securities for both smart contracts and dapps.

Aeternity Blockchain includes a "Decentralized Oracle Machine" that brings in data from outside sources to be used in smart contracts.

 Origin of Aeternity

Aeternity was founded in 2017 by Yanislav Malahov, who famously calls himself the ‘Godfather of Ethereum’. He actually worked a lot for Ethereum, before it was named and he disagreed the process of ethereum. So, he started his own project under the name called        " Aeternity " which had its white paper and initial coin offerings in April 2017. 

The mainnet of Aeternity know as " ROMA " was launched in November 2018.

Special Features of Aeternity 

1. State channels

Smart contracts are built into the blockchain which takes up a lot of space and slows down. total working of blockchain. Aeternity network has solved the above issues by allowing smart contracts to place off the blockchain, or ‘off-chain’. The smart contracts are placed on the blockchain only in case of a dispute, allowing us to hide contracts that we need to hidden.

Aeternity blockchain provides faster service and increased security which many of its competitors fails to provide.

2. Consensus Algorithm 

Aeternity blockchain uses a " Hybrid Proof of Work and Proof of Stake " consensus algorithm. We already know that Proof of Work requires high computational power, which results in a high consumption of electricity. PoW allows people to gain a chance for minning only when they have the most powerful computers.

Instead, Aeternity network uses the " Cuckoo cycle " that works on depending on computer memory bandwidth. This allows any laptops to tablets to mine AE tokens.

3. Oracles 

Aeternity blockchain aims at building a real-world data for smart contracts. For Example, Some contracts require outside informations to be fulfilled such as weather, share price and so on. 

Oracles act as a supporter that retrieve and confirms all those informations on behalf of the smart contracts.

Building Smart Contracts on Aeternity Blockchain

Aeternity blockchain includes more features that set it apart from all other smart contracts and dapp blockchain platforms. It involves an Oracle Machine that brings data into the network from outside sources. This platform allows for the development of functional smart contracts and doesn't support for stateful programming.

As it doesn't support for stateful programming, the parties of the contracts are responsible for maintaining the state of the program. In ethereum, stateful programming is important for building smart contracts or dapps. Aeternity platform renders a way that solves the problem of state sharding which is faced by Ethereum.

Building DApps on Aeternity Network

The DApps developed on aeternity blockchain are called as "aepps" which are open source applications. Aeternity always prioritizes the mobile design and user interface or user experience while developing decentralized application on its platform.

Building useful aepps from day one is the focus of Aeternity to establish a foothold in the crowded DApps platform race. The launch of the mainnet of aeternity demonstrated the capabilities of the Aeternity network.
