Solana remains one of the most popular blockchains for DeFi and NFT activities within the cryptocurrency economy. Despite facing significant challenges, including market volatility and regulatory scrutiny, the network has demonstrated remarkable resilience and continues to attract developers and users.
Understanding Solana’s Architecture
Solana, first launched in 2017, was designed to offer higher base-layer throughput and scalability compared to other Layer 1 (L1) blockchains like Ethereum and Bitcoin. While Bitcoin processes approximately 5 transactions per second (TPS) and Ethereum around 30 TPS, Solana handles about 4,000 TPS, with a theoretical capacity of 65,000 to 75,000 TPS.
This high throughput enables Solana to support near-instant transactions at extremely low costs, making it an attractive alternative to Ethereum for many Web3 developers and users.
Consensus Mechanism: Proof-of-History
Solana utilizes a unique consensus mechanism called Proof-of-History (PoH), a variation of Proof-of-Stake (PoS). PoH optimizes transaction processing by assigning a timestamp to each transaction, allowing Solana to process them in the order they arrive rather than grouping them into blocks. This approach, combined with the network's Tower BFT (Byzantine Fault Tolerance) algorithm, creates a blend of security, efficiency, and speed.
Smart Contracts and Execution
Unlike Ethereum, which uses the Ethereum Virtual Machine (EVM) for smart contract execution, Solana employs a different model for executing "programs." These programs are written in Rust and compiled into WebAssembly bytecode format (WASM), enabling high performance and parallel processing capabilities. This unique smart contract approach contributes to Solana's renowned high transaction throughput and low latency.
Additionally, while Ethereum wallets primarily support ERC-20 tokens and Ethereum-based applications, Solana wallets like Phantom are designed for Solana Program Library (SPL) tokens and Solana-based apps. However, projects like Neon Labs are working on adding EVM compatibility to Solana, allowing Ethereum-based transactions to occur directly on this alternative L1.
Current State of Solana Ecosystem
As of mid-2023, Solana's DeFi ecosystem had a total value locked (TVL) of approximately $266 million, according to DefiLlama data. While significantly lower than its previous peak of about $10 billion, this still positioned Solana as the 11th largest DeFi network at the time.
Solana also maintains an active presence in the NFT space, though its NFT ecosystem remains smaller in both activity and breadth compared to Ethereum's.
The network faces competition from other L1 blockchains like Avalanche and Fantom, as well as from Ethereum's growing Layer 2 solutions such as Arbitrum, Optimism, and Polygon zkEVM. Solana has also navigated significant challenges, including the collapse of FTX (a major stakeholder in many early Solana applications), periodic network outages, and regulatory designation of SOL as an unregistered security.
Despite these challenges, Solana remains a popular choice for DeFi and NFT applications, and its native token SOL continues to rank among the top 15 cryptocurrencies by market capitalization.
SOL Token: Native Currency of Solana
SOL serves as the native token of the Solana network, fulfilling several essential functions within its ecosystem:
- Payment for transaction fees
- Participation in Solana staking
- Medium of exchange in DeFi applications
With a circulating supply of slightly over 400 million tokens and a total supply exceeding 551 million that gradually increases through staking rewards, SOL maintains a significant presence in the cryptocurrency market.
Popular Activities on Solana
Liquid Staking with Marinade Finance
As the largest application on Solana, Marinade Finance offers a liquid staking protocol that enables users to stake SOL tokens using automated strategies. When staking through Marinade, users receive "staked SOL" tokens (mSOL), which can be used in DeFi applications or unstaked at any time to convert back to SOL.
Liquid staking provides an alternative to traditional staking, allowing users to stake any amount of SOL without the typical 1-3 day warm-up or cool-down periods. While instant unstaking incurs a fee ranging from 0.3% to 9%, users can opt for delayed unstaking without fees, though they must wait 1-2 epochs to retrieve their SOL and accumulated rewards.

Trading on Raydium
Raydium is a decentralized exchange (DEX) built on Solana that offers fast trading and liquidity mining opportunities. Users can leverage Raydium's trading interface to swap SOL and SPL tokens through liquidity pools or use limit orders for more advanced trading strategies. The platform also provides multiple ways to earn RAY tokens, such as providing liquidity to trading pools or staking, making it an attractive option for those beginning their DeFi journey on Solana.
NFT Trading on Magic Eden
Magic Eden has established itself as the leading NFT marketplace on Solana, featuring over 8,000 listed NFT collections. The platform serves as a one-stop destination for discovering and trading Solana NFTs, offering exclusive minting projects through its Launchpad service and partnerships with NFT brands. Users can also explore NFT gaming through Eden Games, which focuses on supporting game creators and their communities.
Additional Solana Applications
For those interested in further exploring the Solana ecosystem, several other applications represent some of the most popular projects on the network:
- Lido — Liquid staking | $54 million TVL
- Orca — Decentralized exchange (DEX) | $36 million TVL
- Solend — Lending and borrowing | $37 million TVL
- Atrix — Decentralized exchange (DEX) | $15 million TVL
- Francium — Leveraged yield farming | $12 million TVL
These projects offer diverse functionalities and use cases that demonstrate Solana's potential and application scenarios across various sectors of the cryptocurrency economy.
Frequently Asked Questions
What makes Solana different from Ethereum?
Solana differs from Ethereum primarily in its consensus mechanism (Proof-of-History versus Proof-of-Stake), transaction throughput (4,000+ TPS versus ~30 TPS), and smart contract execution (Rust programs compiled to WASM versus EVM bytecode). These differences result in lower fees and faster transactions on Solana, though Ethereum maintains a larger ecosystem and greater decentralization.
How secure is the Solana network?
Solana employs a combination of Proof-of-History and Tower BFT consensus mechanisms to ensure network security. While the network has experienced occasional outages, the core protocol has remained secure against attacks, and the development team continues to work on improving network stability.
Can I use Ethereum tools with Solana?
While Solana uses a different programming model than Ethereum, projects like Neon Labs are working to add EVM compatibility to Solana. This would allow developers to use Ethereum tools and deploy Ethereum-compatible smart contracts on the Solana network.
What wallets support Solana?
Several wallets specifically support Solana and SPL tokens, including Phantom, Solflare, and Ledger hardware wallets. These wallets are designed to interact with Solana-based applications and manage SPL tokens.
Is Solana environmentally friendly?
As a Proof-of-Stake variant, Solana consumes significantly less energy than Proof-of-Work blockchains like Bitcoin. The network's efficiency contributes to a lower environmental impact compared to traditional blockchain systems.
What caused Solana's network outages?
Solana has experienced periodic network outages primarily due to resource exhaustion and network congestion issues. The development team has implemented several upgrades to address these concerns and improve network stability over time.
