Solana is a next-generation blockchain, designed to offer ultra-fast and low-cost transactions. It manages to do this while maintaining a high level of security and decentralization. This network has attracted a lot of attention thanks to its innovative architecture, which overcomes the limitations of other blockchains, such as Ethereum.
In this article, we will dive into the technical aspects of the Solana blockchain. How does it work internally? What are its decentralized applications (DApps)? What role does it play in the decentralized finance (DeFi) ecosystem? After writing a critical article on Solana, this time I focus on the technical aspects of this promising blockchain.
Solana Blockchain Architecture and Operation
Solana stands out with several technical innovations. These allow it to achieve high scalability and high performance. Here is an overview of the key technical components:
Proof of History (PoH) :
Concept: PoH is a mechanism for synchronizing events and transactions based on a sequential hash function. Solana uses the SHA256 function to generate a verifiable timestamp for each transaction. This process allows for a chronological ordering of events, without the need for global consensus at each step.
How it works: Nodes validate transactions and timestamp them locally. This eliminates the need to constantly synchronize all nodes. The result? A significant reduction in validation times and increased blockchain throughput.
Tower BFT (Byzantine Fault Tolerance) :
Description: Tower BFT is a variant of the Practical Byzantine Fault Tolerance (PBFT) consensus. It is optimized to use the timestamps provided by PoH. Validators can vote on the state of the network with minimal communication, while providing enhanced security against attacks.
Advantages: This mechanism reduces block confirmation times. It also improves security, ensuring that the blockchain remains resilient even if some nodes fail.
Gulf Stream :
Mempool-Free Transaction Forwarding: Gulf Stream allows transactions to be forwarded to validators before blocks are even created. This allows the network to process transactions on the fly. This reduces latency.
Effect on TPS: By removing traditional mempools, Gulf Stream directly contributes to increasing the number of transactions per second (TPS) that Solana can handle.
Sealevel :
Parallel Smart Contracts Runtime: Sealevel enables parallel execution of smart contracts. Unlike Ethereum, where contracts are executed sequentially, Sealevel takes full advantage of the multi-core capabilities of modern processors. The result: increased overall performance.
Scalability: With Sealevel, Solana can run thousands of smart contracts simultaneously. This is essential for the large-scale deployment of complex DApps.
Turbine :
Broadcasting Optimization: Turbine divides data into small packets. It distributes them across the network in a hierarchical manner. This improves the efficiency of broadcasting block data and ensures rapid propagation of information across the network.
Cloudbreak :
Horizontal Scaling Database: Cloudbreak is Solana's database system. It is designed to be horizontally scalable. It manages concurrency to data, allowing the network to maintain high performance even under heavy load.
DeFi on Solana: State of Play and How it Works
Decentralized finance on Solana has grown rapidly, largely due to the blockchain’s technical features. These allow for fast and inexpensive transactions. Here’s a look at the top DApps and how they work on Solana:
Serum :
Central Limit Order Book (CLOB): Serum is a unique DEX. It uses a centralized order book while remaining decentralized. CLOB is hosted on Solana, allowing for instant transactions and near-zero fees.
Integration with other DApps: Serum serves as the foundation for many other DeFi projects on Solana. It acts as a liquidity engine for the entire ecosystem.
Raydium :
Automated Market Maker (AMM): Raydium works like a classic AMM. But it is integrated with Serum. This allows users to benefit from both the liquidity of the AMM and the order book of Serum.
Yield Farming and Staking: Users can provide liquidity and participate in yield farming, earning rewards for their participation.
Metaplex :
NFTs on Solana: Metaplex makes it easy to create, manage, and sell NFTs. The network allows creators to launch NFT collections with significantly lower minting and transfer fees than other blockchains like Ethereum.
According to data from DeFiLlama, the total value locked (TVL) on Solana stands at around $350 million. Protocols like Serum and Raydium dominate this space.
Using DeFi on Solana via Binance Web3 Wallet
For those looking to interact with DeFi on Solana via Binance's Web3 wallet, here's how:
Installation and Configuration: Install the Binance Web3 wallet. Configure it to interact with Solana. Import your private keys or create a new wallet. Then, add the Solana network to the wallet settings.
SOL Deposit: Transfer SOL to your wallet from Binance. You can also buy SOL directly via the wallet.
Interaction with DApps: Connect to DApps like Serum or Raydium via the wallet. The Web3 wallet allows you to securely sign transactions and easily interact with DApps in the Solana ecosystem.
DeFi Participation: Use DeFi services like staking, yield farming, or trading on Solana DEXs. Take advantage of low fees and fast network speeds.
Solana is positioned as a cutting-edge blockchain, with technical innovations that make it particularly suited to support large-scale and complex decentralized applications. The DeFi ecosystem on Solana, while still in development, already offers interesting opportunities for users and developers. However, as with any investment, it is crucial to understand the risks and do your own research before committing.
A future, more technical article will explore in detail the underlying mechanisms of Solana, including its specific architecture, protocols, and potential for future evolution.
