What Is Solana (SOL)?

Introduction

Scalability is one of the main challenges facing blockchain technology. As these networks evolve, transaction speed and confirmation times are often limited. Solana has successfully overcome these barriers with its innovative architecture while ensuring security and decentralization.

Founded by Anatoly Yakovenko in 2017, the Solana blockchain is supported by the team at Solana Labs. Today, Solana has become one of the most widely used blockchains globally. By adopting several innovative technologies, such as Proof of History (PoH) and parallel processing, Solana is capable of achieving high efficiency with tens of thousands of transactions per second (TPS).

How Solana Works

Solana is a third-generation proof-of-stake (PoS) blockchain. It achieves high throughput, fast transactions, and low fees through several unique innovations:

Parallel Processing: The ability to handle multiple transactions simultaneously.

Proof of History (PoH): A method for time verification that does not rely on traditional timestamps.

Tower Byzantine Fault Tolerance: An optimized practical Byzantine Fault Tolerance (BFT) scheme that integrates PoH.

Turbine: A block propagation protocol that ensures network synchronization.

Gulf Stream: A transaction forwarding protocol that operates without a memory pool.

Solana Virtual Machine: A system that supports the execution of parallel smart contracts.

These technologies endow the Solana network with high performance, achieving a block time of just 400 milliseconds and a transaction processing capacity of tens of thousands of TPS. In comparison, Bitcoin has a block time of approximately 10 minutes, while Ethereum's block time is around 15 seconds.

SOL holders can choose to stake their tokens to participate in the blockchain's PoS consensus mechanism. With compatible cryptocurrency wallets, users can delegate their tokens to validators responsible for processing network transactions and share in the rewards upon successful validation. This incentive mechanism encourages both validators and delegators to prioritize the network's interests.

Proof of History

In the cryptocurrency domain, tracking the sequence of transactions is crucial. Bitcoin achieves this by bundling transactions into a block with a timestamp, but this process often leads to longer confirmation times for nodes. Solana introduces the innovative Proof of History (PoH) method.

Solana processes events and transactions using the SHA256 hash function, where each input generates a unique and unpredictable output. The output value of each transaction is used as the input for the next hash operation, thereby embedding the transaction order within the hash outputs.

This hashing process creates a continuous chain of hashed transactions, enabling validators to clearly verify the order of transactions within blocks without relying on traditional timestamps.

While hashing requires some time, validators can easily compute the total elapsed duration. By sorting transactions in the hash chain, the volume of information processed and passed through each block is reduced. Using the latest version of the hash of transaction states can significantly shorten block confirmation times.

It is important to note that Proof of History is not a consensus mechanism but rather a method to accelerate the confirmation of transaction order. When combined with proof of stake, the selection of the next validator becomes more efficient, drastically reducing the time nodes take to validate transaction sequences, allowing the network to quickly choose new validators.

Low Cost

Solana's transaction fees are extremely low, with an average cost of just $0.00025 per transaction. This low fee structure significantly lowers the barrier to entry for users looking to engage with Web3, as gas fees on other blockchains can often substantially increase the cost of individual transactions.

Energy Efficiency

Solana has become one of the most energy-efficient blockchains due to the minimal time and resources required for its nodes to validate transactions, without relying on mining as seen in proof-of-work (PoW) networks.

The Solana Foundation, a non-profit organization dedicated to protecting and supporting the Solana network, regularly publishes third-party audit reports on Solana's energy consumption and compares it with other blockchain projects as well as average household energy consumption levels. The latest report released in 2023 indicated a 25% reduction in energy consumption per transaction, decreasing from 0.879 kJ to 0.658 kJ.

What is Solana (SOL)?

SOL is the native utility token of Solana and is part of a deflationary model in which the Solana network regularly burns a portion of SOL tokens. Users are required to use SOL to pay transaction fees when transferring tokens or interacting with smart contracts. Additionally, SOL holders can become validators on the network. Similar to Ethereum, Solana supports developers in building smart contracts and creating projects on its blockchain.

SOL utilizes the SPL protocol, which is the token standard for the Solana blockchain, akin to Ethereum's ERC20. The SOL token primarily serves two main purposes:

To pay transaction fees incurred during network or smart contract interactions.

To act as a staking token as part of the proof-of-stake consensus mechanism.

Decentralized applications (DApps) built on Solana create new use cases for SOL and other tokens that utilize the SPL standard.

Solana Ecosystem

Since the launch of its mainnet beta in 2020, the Solana ecosystem has experienced significant growth. As of January 2024, over 2,500 developers are engaged in Solana projects, and the number of active wallets on the Solana network exceeds 1 million.

Many traditional economic giants have also announced their foray into Solana. For example, Discord allows users to link their Solana wallets on their profiles, while ASICS utilizes the Solana Pay payment system to sell limited-edition sneakers.

With its fast transaction speeds and high throughput, Solana has become the preferred network for various Web3 use cases.

Decentralized Physical Infrastructure Networks (DePIN): Real-world networks that employ token rewards, such as the decentralized mapping protocol Hivemapper, are made possible by Solana’s ability to process transactions quickly.

Next-Generation NFTs: The Solana ecosystem has introduced a new non-fungible token (NFT) system that leverages its scalability to create new use cases. Executable NFTs (xNFTs) from Coral are NFTs that can launch programs, fully existing within a user's wallet's network and application stack. Compressed NFTs (cNFTs) use Merkle trees to significantly reduce the cost of on-chain data storage, allowing the cost of minting a million NFTs to drop from millions of dollars to just hundreds.

Payment Systems

The Solana Pay protocol supports a seamless and permissionless payment ecosystem, enabling businesses to complete transactions within seconds. This efficient payment method enhances the convenience of transactions and improves the user experience.

Gaming and Entertainment

With its extremely low latency, Solana can handle large volumes of transactions, opening up new Web3 application scenarios for gaming, entertainment, and metaverse functionalities. This high performance creates rich possibilities for developers and drives innovation in the industry.

DeFi

Solana's high throughput and low fees provide a reliable foundation for building automated market makers and decentralized trading platforms. This advantage enables DeFi projects to thrive on Solana, attracting a large number of users and developers.

Conclusion

Since entering the blockchain space in 2020, Solana has gradually evolved into a robust and sustainable ecosystem, becoming a popular choice for numerous projects and users, with strong potential for continued growth in the future.

Risk Warning

While the cryptocurrency market offers significant growth potential and innovation opportunities, it also carries a high level of market risk and price volatility. The value of crypto assets can fluctuate dramatically in a short period, potentially leading to substantial financial losses for investors. Additionally, the cryptocurrency market faces multiple risk factors, including technical risks, legal and regulatory uncertainties, cybersecurity threats, and market manipulation. We strongly advise users to conduct thorough research and due diligence before making any investment decisions and to consult professional financial advisors. All investment decisions are made at the user’s own risk. Thank you for your trust and support of Venkate!
