Understand the Basics of Solana

The first thing you need to learn before you find how to deploy smart contract using Solana is the fundamentals of Solana. It is a high-performance blockchain platform that supports dApp development and trading crypto exchanges. The meaning of ‘high performance’ with respect to Solana blockchain is the ability to resolve scalability and congestion issues. Solana utilizes a specialized consensus mechanism, Proof of History consensus, which helps in achieving faster block confirmation times with better efficiency. Proof of History consensus has made Solana one of the fastest blockchain platforms.

The review of Solana smart contract example would help you understand how it has emerged as the most efficient blockchain network in the world. Proof of History helps in using historical evidence for creating records that could verify that certain events happened at a particular instance in time. The unique consensus mechanism uses a high-frequency verifiable delay function for verifying events.

Upon processing a transaction or event, it has a unique hash and calculation that could be universally verified. The calculation works as a cryptographic timestamp that can help in determining the time when a specific event or transaction happens. Every node on Solana features a cryptographic clock, which helps in tracking the time of the network and sequence of events. As a result, nodes can offer better throughout and efficiency on Solana blockchain.

Architecture of Solana Smart Contracts

The next important highlight you must learn before developing smart contracts on Solana blockchain is the architecture of Solana smart contracts. Solana features an alternative to smart contracts with programs. Solana follows two distinct workflows for development of smart contracts and dApps. In addition, the answers to “What language is used in Solana smart contract development?” also point to simple alternatives, such as C, C++, and Rust. Solana programs or smart contracts can be deployed on the chain and operate with the ‘Solana Runtime’ feature.

Solana follows a completely distinct smart contract model as compared to traditional EVM-based blockchains. The code and the state of the smart contract code are combined in one contract in conventional blockchains. On the contrary, Solana smart contract development involves stateless smart contracts, which include the program logic only. External accounts can interact with the smart contracts deployed on Solana blockchain for storing data associated with program interaction.

This way, you can ensure logical isolation of contract code from state, which serves as a major advantage for smart contract development with Solana. Furthermore, Solana also offers the options of Command Line Interface and JSON RPC API for facilitating interactions with dApps. Decentralized apps could also interact with Solana programs and the blockchain by utilizing existing SDKs.

Workflow of Smart Contracts on Solana

The comprehensive review of a Solana smart contract example would help you understand the workflow of a smart contract architecture on Solana. The Solana Program is the section that helps in creating smart contracts with C, C++, and Rust and deploying them on Solana blockchain. In the second step, users would have to develop decentralized apps with the support of client SDKs alongside JSON RPC API for using Solana programs.

On top of it, the ‘Client’ section in Solana smart contracts focuses on creating decentralized apps for interacting with programs deployed on Solana blockchain. Decentralized apps could interact with different deployed programs to ensure transaction submission through client SDK. The ‘Program’ and the ‘Client’ sections of the smart contract work in collaboration with each other to develop an ecosystem of dApps and smart contracts for updating the state of the Solana blockchain.

Why Should You Create Solana Programs rather than Smart Contracts?

The benefits of Solana programs ensure that they are important alternatives to the traditional smart contracts on other blockchains. Solana is one of the biggest competitors to Ethereum even with the similarities with other blockchains. The primary reason to deploy smart contract using Solana is the benefit of cost-effective smart contract development.

Ethereum developers have been experiencing problems due to extremely high transaction fees, which can rise exorbitantly during network congestion. Solana offers better throughput than Ethereum as it can manage more transactions per second, thereby reducing costs.

The faster transaction speeds could ensure that Solana can compete against popular centralized payment processors. Solana programs can play a vital role in improving the speed and scalability of crypto networks alongside making them more accessible. With a crypto wallet that holds SOL tokens and Solana-based tokens, you can leverage the facilities of interacting with different apps available on Solana ecosystem.

Users can also exchange a token for another on a decentralized exchange of their choice or purchase NFT from a marketplace in the Solana ecosystem. Irrespective of the type of transaction you do on Solana, you would have to pay a smaller fee than the one you have to pay on Ethereum.
