Solana is a blockchain network focused on fast transactions and increased throughput.

Solana Blockchain was launched in 2017 by Anatoly Yakovenko of Solana Labs. Solana's goal is to break scalability bottlenecks without compromising security or decentralization.

As the cryptocurrency market continues to grow in popularity, users of ethereum, the king of the smart contract public chain, are also increasing, resulting in high Gas bills and congested networks, forcing users to find new public chains. There is an "impossible triangle" in the public chain world, in which decentralization, security and scalability cannot be achieved at the same time. The major public chains are primarily decentralized and secure, so scalability becomes the goal of many new public chains. That gave Solana an opportunity. Solana has positioned itself as the fastest high-performance public chain in the world, with network level scalability and theoretically up to 710,000 TPS for standard gigabit networks.

Solana combines proof of stake (PoS) with eight core technologies including PoH (proof of history), Tower BFT, Turbine, Gulf Stream, Sealevel, Pipeline, Cloudbreak and Achievers, To ensure unparalleled decentralization and security within the network.

Solana is the highest-performing decentralized network ever, without sacrificing decentralization.

Several technological innovations enable Solana's TPS to match the performance of a centralized network.

At its inception, Solana blockchain issued 500 million SOL tokens. While the supply of coins inflates when block rewards are paid to verifiers, Solana also reduces the supply of tokens by partially destroying transaction fees paid by users. This will also be implemented in conjunction with other token destruction transactions, ensuring that the total SOL supply remains at around 500 million coins.

Proof of History (PoH) : Without the need for nodes to communicate a consensus clock, Solana's PoH consensus algorithm makes it easier for the system to track the chronological order of transactions by building a history of transactions, enabling users to build more efficient and throughput applications and exchanges based on Solana protocols. Tower BFT: PoH optimized version of Practical Byzantine fault tolerance, Tower BFT is a consensus algorithm similar to PBFT (Practical Byzantine Fault tolerance Algorithm) designed to take advantage of synchronous clocks. Tower BFT plays the role of cryptoclock with PoH mode to facilitate network consensus, reducing the time and cost of numerous node communication and transaction delays. Turbine: A block propagation protocol that makes it easier to transfer data between blockchain nodes by breaking it up into smaller packets. This allows Solana to address bandwidth limitations and increase its overall capacity, allowing transactions to be completed more quickly. Gulf Stream: A no-memory pool transaction forwarding protocol, the Gulf Stream protocol plays an important role in driving the transaction cache and pushing it to the edge of the network. This allows validators to execute trades earlier, which reduces transaction confirmation time, faster Leader rotation, and reduces the cache pressure on validators in the pool of unconfirmed trades, allowing Solana to process 50,000 transactions per second. Sealevel: Parallel smart contract runtime system, Sealevel is a highly parallel transaction processing engine that makes Solana execution time more efficient and allows transactions to be executed simultaneously on the same state blockchain. Pipelining: Used to validate optimized transaction processing units,Pipelining is where incoming data flows are allocated to the different hardware responsible for processing the data. This transaction processing module enables transaction messages to be quickly verified and propagated among all nodes in the network. Cloud storage (Cloudbreak) : Horizontally expanded account database, Cloudbreak data structure, suitable for the entire network at the same time parallel data read and write, Solana network to achieve the characteristics of rapid expansion. Archivers: Distributed ledger storage. We use Archivers for data storage. Data on Solana's network is moved from Validators to a network of nodes called Archivers. These nodes can be lightweight devices such as laptops, and systems are checked frequently to ensure that the data stored in these nodes is correct.

SOL holders earn rewards by pledging SOL.

In NEAR the use of "night shadow agreement" subdivision technology compared to Solana adopted based on the PoH clock mechanism, optimize the consensus mechanism, data broadcast, parallel transaction processing, with a separate node network status data storage, etc., the purpose is in order to guarantee a certain degree of decentralization and security situation, achieve high throughput and low delay and low cost, In this way, user requirements in most scenarios can be met.

Solana combined PoH and PoS, etc., and went out of its own way to improve performance. Although it did not reach 710,000 TPS in theory, it has exceeded 50,000 TPS in practice. The network design and code writing took a long time, the update frequency was maintained well, and it was audited by Kudelski Security for two months.

The crypto community's confidence in Solana's ability to support DApps in the future is already reflected in the SOL native token, which at one point topped $200. As cryptography moves into the multi-chain arena, Solana is emerging as an unrivalled platform for dApps that require low latency and high scalability.

Code loopholes, fierce competition, ecological construction remains to be seen.

Despite the recent London upgrade to Ethereum, there are still significant concerns among developers about its speed and scalability, which could severely limit the future growth of the Ethereum ecosystem. As networks become more saturated, high Gas charges and slow transaction times have frustrated many users and DApp developers, leading to a growing demand for more scalable and computation-efficient Layer 1 architectures in the crypto market.

As the governance token of Solana platform, SOL is mainly used for pledge. Its transaction fees have become a prop for its price. SOL is not meant to be an Ethereum killer, but to help ethereum expand its ecosystem and make DeFi more important. SOL's wormhole protocol will allow ethereum to be more connected to SOL, enabling greater expansion and boosting its value. Improved security will also help more DEFI projects develop over SOL.
