What is Solana?

Solana is a third-generation blockchain focused on interoperability and scalability. Since its inception in 2017, Solana has solidified its position in the crypto market while its native token, SOL, at the time of writing, is the 5th largest crypto asset by market capitalization.

Solana’s affordability, efficiency, and speed have made it an attractive option for developers looking to build decentralized applications (dApps) and issue tokens on this blockchain. Its strong user growth, despite numerous outages, has made it a rival to top smart contract-enabled blockchain platforms like Ethereum (ETH).

In this guide, we’ll delve deeper into what is Solana, the basics of Solana, technical innovations, and its ecosystem. In addition, we’ll also look into the blockchain’s role in decentralized finance (DeFi), non-fungible tokens (NFTs), touch Solana meme coins, and examine its challenges and prospects.

Remember, you can use Trust Wallet as your Solana wallet, as well as explore the Solana ecosystem safely.

The Fundamentals of Solana

Before we delve into other aspects of this blockchain, let’s start by answering the basic question, “What is Solana?”

Solana is a blockchain-powered network that aims for mass adoption. The protocol was created to solve two out of the three blockchain trilemma issues by lowering transaction costs and improving scalability, all while providing a secure platform for developers to build dApps.

The blockchain trilemma refers to the notion that it’s difficult to achieve the highest levels of all three blockchain pillars - decentralization, scalability, and security - simultaneously.

Solana utilizes the proof-of-stake (PoS) consensus mechanism, which is supported by additional solutions such as the proof-of-history (PoH) method. The combination allows Solana to process transactions much faster than, for example, Ethereum.

The PoS consensus mechanism permits validators on the Solana blockchain to confirm transactions that are being added to this blockchain. On the other hand, the PoH feature enables those transactions to be verified and timestamped quickly. We’ll go deeper into Solana’s unique consensus mechanism shortly.

As a fast-growing blockchain, Solana stands out from other blockchain technologies for various reasons:

• Gas Fees: Solana is one of the fastest and cheapest blockchains. The blockchain can process thousands of transactions per second (TPS) with relatively low gas fees (at the time of writing, around 0.02 USD).

• Growing Ecosystem: Solana’s blockchain ecosystem has rapidly grown to rival other blockchains since its inception, even surpassing Ethereum in daily trading volume on decentralized exchanges in May 2024. The blockchain is also home to hundreds of Solana meme coins and dApps. The Solana DeFi and NFT ecosystem also continues to burgeon (but still lagging behind several other major blockchains)

• Transactional Speed: Solana claims it can process around 60,000 transactions per second. However, in reality, the actual number is much lower. At the time of writing, it stands at around 2,600. Moreover, the blockchain’s block time is 400 milliseconds, compared with Ethereum’s 12 seconds. This means that a new block can be added to Solana in that amount of time.

At the heart of the Solana blockchain is its native digital currency, SOL. The SOL token plays a crucial role in helping Solana power smart contract operations utilized by dApps and pay transaction fees on the network.

Beyond its transactional role, SOL is also key in Solana’s governance model. Token holders can stake their SOL and participate in the protocol’s consensus mechanism. By locking up a specific amount of their tokens, holders of SOL can help verify transactions and secure the blockchain. In exchange, stakers are incentivized with more SOL tokens for upholding the network’s integrity. According to the developers of the blockchain, there's no strict minimum amount of SOL needed to become a validator.

Technical Innovations of Solana

Solana uses the PoS consensus mechanism that is supported by the PoH feature. PoH, introduced by Solana's co-founder Anatoly Yakovenko in Solana's 2017 whitepaper, is a method designed to make blockchain transaction ordering more efficient, thereby aiding in faster transaction processing.

PoH allows a blockchain to attain consensus by verifying the order and passage of time between transactions and recording that into a ledger. Every node on the network relies on the encoded passage of time in the ledger, which is important for the functioning of the blockchain network.

While Solana’s consensus mechanism plays a key part in helping it achieve its high throughput speed and low latency, it’s not the only feature. The blockchain incorporates other features that help it achieve its overall mission. These features include:

• Cloudbreak: An innovative feature on Solana that addresses the scalability issue of the blockchain. The Cloudbreak allows Solana to handle large transaction volumes and take on more load.

• Gulf Stream: With Gulf Stream, Solana can run without a mempool, which is a usual space in other blockchains where transactions are waiting to be picked up and confirmed. It improves the overall network efficiency by optimizing transaction processing and reducing confirmation times.

• Pipeline: To allow for faster transaction processing, Solana incorporates a pipelining technique that permits the parallel processing of transactions. Using the pipeline feature, transactions in Solana get separated into three stages - fetching, processing, and write-back.

• Sealevel: Smart contracts on Solana can run simultaneously thanks to the Sealevel feature. This makes Solana a money and time-saving blockchain as many smart contracts can run in parallel.

• Tower Byzantine Fault Tolerance (BFT): As a reminder, the BFT method helps a blockchain system operate even with some faulty nodes. Meanwhile, Tower BFT uses a practical implementation of BFT, PBFT, which also utilizes the aforementioned proof-of-history method to establish the order of transactions and blocks.

The Ecosystem and Applications

Beyond being a blockchain, Solana’s growth and use amongst developers have significantly contributed to its growing ecosystem which is abuzz with activities. This has resulted in a wide range of applications being built atop the Solana blockchain.

The Solana ecosystem is home to NFTs and various dApps that cut across decentralized finance. This is because of its high throughput speed and low transaction fees. Beyond the Solana DeFi and NFT ecosystems, the blockchain is also home to numerous gaming projects.

With 264 dApps in the Solana ecosystem, below are the top five Solana dApps according to data from DappRadar:

• Jupiter Exchange: Jupiter is a decentralized exchange (DEX) aggregator that connects to all DEX markets and automated market maker (AMM) pools to compare the prices between markets on different DEXes.

• Raydium: Raydium is an AMM that offers services such as trading, earning yield, and launching new Solana projects.

• MomoAI: MomoAI is an AI-agents-driven Web3 social entertainment product platform that allows developers to focus more on creating and designing games while transferring the complexity of technical implementation to AI.

Solana's Role in the DeFi, NFT, and Meme Coins

Over the years, the decentralized finance space has experienced significant growth with the emergence of various blockchain networks. Since its launch, the Solana ecosystem has witnessed rapid growth, which has also impacted the creation of DeFi projects and protocols on the platform. This growth has been fueled by Solana’s scalability offering.

Since Solana can process thousands of transactions per second, it has become a popular choice for developers looking to build DeFi applications that need high throughput speeds. Compared to blockchains like Ethereum, Solana also offers low transaction fees.

It makes it more cost-effective for people to access and interact with DeFi protocols. But the DeFi sector isn’t the only space that blockchains like Solana have had an impact on. Solana has also contributed to the growth of the NFT market.

Solana is home to a thriving NFT market that permits people to access and explore different digital collectibles from various collections. At the time of writing, Solana is third in NFT trading volume, following only Bitcoin and Ethereum.

Ethereum’s high gas fees make trading NFTs on its platform an expensive affair. However, Solana’s low transaction costs make it a more affordable alternative. Essentially, Solana lowers the barrier of entry for creators and collectors.

Another area where Solana is making waves is in the meme coin space. The Solana meme coin space, similar to the Solana DeFi and NFT space, has been experiencing rapid growth. The creation of meme coins on Solana has helped to attract new developers and investors and grow the crypto market. However, it has also attracted numerous scam projects.

The development of Solana meme coins has also resulted in the creation of a meme coin community that’s active and engaged. And because it supports various programming languages, such as Rust, C, C++, developers have more options to use Solana.

Challenges and Future Prospects

Despite Solana’s positive contribution to the crypto space, the blockchain hasn’t been flawless. Similar to other blockchains, Solana has also had its fair share of challenges.

One such challenge has been numerous network outages which have raised questions on its reliability. In February 2024, Solana had a major network outage that lasted for five hours, rendering the blockchain unusable. Its developers have attributed the network outages to a software bug. Solana has so far had nine major and multiple partial network outages since its inception.

Another challenge that Solana has faced is network congestion which has over time, resulted in transactions failing. The blockchain attributes its network congestion issues to increased demand for its block space and negligence to execute patches associated with its networking stack promptly.

Solana has also had to deal with centralization concerns due to a relatively low number of validators and their concentration.

Still, the team behind Solana has been responsive to the issues plaguing it and is working on improvements and solutions. As Solana continues to innovate, we can expect the introduction of new features that are geared towards enhancing the network and by extension, the user experience.

Conclusion
