Solana review

Review: Solana


Many investors are eager to discover what Solana offers to the plate, as recent surveys suggest that Solana is held by one-third of significant crypto holders and institutions.

  • The speed of transactions on Solana is possibly its best selling feature. Because of its speed, Solana may be the best possible alternative to Ethereum among all cryptocurrencies.
  • Solana is also quickly expanding its market share in the area of non-fungible high-growth tokens.
  • Currently, the computer power required for mining Bitcoin and using its PoW mechanism to validate transactions results in an annual carbon dioxide production of around 60 million tons. Solana uses a small amount of energy.
  • Investors might not be able to depend as much on Solana's network reliability as they can with Ethereum because it has a smaller user base and a less established history.
  • Because of its first-mover advantage, Ethereum has a far larger number of projects than Solana. There are 2,887 Ethereum dApps available at the moment. Solana asserts that it has roughly 350 total projects on its network
  • There aren't always the same number of coins in Solana. Solana initially increased its output by 8% annually.

Business score: 4.6/5


Solana is an open-source project that works on a new permissionless and ultrafast layer-1 blockchain. The main Unique Selling Point of Solana should be its transaction speed which is the best in the business and is expected to improve even further. Solana is a blockchain that supports smart contracts, non-fungible tokens (NFTs), and a variety of decentralized applications (dApps). Staking and a means for transferring value are both provided by the SOL coin, which is native to Solana’s blockchain. The Solana blockchain was launched during the 2017 ICO frenzy. The internal testnet for the project was begun in 2018, with further testnet phases leading up to the main network’s official debut in 2020.


The Solana project was founded in 2017 by Anatoly Yakovenko and Raj Gokal, a current Solana board member and Chief Operations Officer. Yakovenko wanted to apply his knowledge to a new blockchain paradigm that allowed for faster processing speeds. Yakovenko proposed a brand-new distributed systems timekeeping method called Proof of History in the initial whitepaper (PoH). In February 2018, Yakovenko and Greg Fitzgerald, a coworker at Qualcomm, released the project’s initial internal testnet, demo network, and first official whitepaper. Solana has created approximately 50 million blocks since the mainnet launched in 2020 and has enjoyed significant growth.


The high-performance blockchain from Solana does not end with its current BFT PoS-based consensus protocol. The roadmap for the Solana Foundation reveals that delegated Proof-of-Stake is intended for use on the mainnet (dPoS). Solana network participants will be able to take part in the process of creating blocks when Solana switches to a dPoS system. By either staking their own tokens to become validators themselves or transferring their tokens to validators they are confident in, validators will be able to profit. Using Solana, anyone may join the network as a validator. The overall security of the Solana network can be improved by validators. Although there is no minimal stake requirement in Solana, the leader selection procedure is stake-weighted. The method through which a validator gets to suggest the following block is part of the leader selection process.

Technical: 3.8/5


Some of the unique features offered by Solana:

Proof of history (PoH): Despite its name, PoH is a cryptographic clock that allows nodes to agree on the temporal sequence of events on the chain without having to communicate with one another. By maintaining past records of transactions and making it easier for the system to keep track of the order of events, PoH helps the network become more efficient and throughput increases.

Byzantine fault tolerance tower: Solana’s pBFT (practical Byzantine fault tolerance) implementation, Tower BFT, is optimised for PoH. This is, in essence, a consensus method that uses the cryptographic clock to reach a decision without having to send a lot of messages between nodes. This makes transactions go faster.

Gulf Stream—a transaction forwarding mechanism that does not need a mempool. Solana can reach 50,000 TPS because of the Gulf Stream. This protocol is in charge of caching transactions and transmitting them to the network’s edge. This lets network validators run transactions ahead of time, which greatly reduces the time it takes to confirm transactions and the amount of memory needed by validators for unconfirmed transaction pools.

Turbine: Turbine is a block propagation technology that divides data into smaller chunks to make data transmission between nodes easier. Solana Turbine assists Solana in resolving bandwidth difficulties and speeds up the network’s overall transaction processing.

Sealevel—smart contract processing in parallel. Solana is able to grow horizontally across GPUs and SSDs thanks to this parallelized transaction processing engine. In short, Sealevel lets many transactions happen on the same chain, which speeds up the network.

Pipelining: In CPU architecture, pipelining is a prevalent technique. It is the assignment of a stream of input data to various devices for processing. This allows for speedier replication and validation of transaction information across network nodes.

Cloudbreak: Cloudbreak is a data structure that is essential for scalability and performance in the network. It organises the account database so that the 32 threads of the network can read and write at the same time.

Archivers: The data is offloaded by Solana’s validators to archivers, a network of nodes. Archiver nodes are simple laptops or PCs that are used by the network to store data.


A more advanced variant of the practical Byzantine fault tolerance (pBFT) protocol, the Tower Byzantine fault tolerance (BFT) algorithm, is used by PoH to rely on PoS. Solana uses it to get an agreement. As a second layer of transaction validation, the Tower BFT maintains the network operational and safe. PoH is also referred to as a high-frequency Verifiable Delay Function (VDF), which is a three-step procedure that includes setup, evaluation, and verification and yields distinctive and reliable findings. By demonstrating that the network has had enough time to advance, VDF keeps the network in order.

In order to produce a 256-bit output, the 256-bit secure hash algorithm (SHA-256), used by Solana, consists of a series of proprietary cryptographic operations. The network periodically samples the number of SHA-256 hashes and provides real-time data based on hashes stored on central processing units. A specific piece of data that was generated before a certain hash index was formed can be recorded by Solana validators using this set of hashes. After this particular piece of data has been supplied, the transaction timestamp is created. All nodes on the network must have cryptographic clocks to keep track of events in order to accomplish the promised high TPS and block generation time frames as opposed to relying on other validators to validate transactions.


The usual goal of distributed denial-of-service attacks is to render a network useless. Unrighteous people try to overload a network by sending an excessive volume of bandwidth its way in order to prevent end users from using it. Unfortunately, Solana has been the target of DDoS assaults before, experiencing a 17-hour downtime in September of last year. The vulnerability of this network to assaults may or may not be known to Solana’s investors, although several pretty significant institutional investors have brought it to their attention. Solana is undoubtedly a fantastic long-term investment option for a wide range of factors. Rock-bottom fees and comparatively quick transaction times are the results of this network’s special proof-of-history validation technique (akin to proof-of-stake but far more effective). As a result, the Solana network has a distinct advantage over its rivals that attracts many cryptocurrency investors. These assaults, however, raise alarm. The attack reduced network speed, and even while Solana was still up, security issues now seem to be outweighing the network’s otherwise positive thesis.


Many investors are eager to discover what Solana offers to the plate, as recent surveys suggest that Solana is held by one-third of significant crypto holders and institutions. For most, if not all, of the top cryptocurrencies on the market, 2022 has been a difficult year despite many of the largest names in the industry seeing substantial upward momentum throughout 2021. The bulls have not recently had favorable SOL price behavior. From a recent high of about $205, SOL has decreased by almost 80% during the last few months. So, there is reason to be optimistic about the near future because the selling pressure at the highs was not as strong as the buying pressure at the lows.
