Solana Ecosystem Explained: A Guide To The Major Ethereum Killer
Solana is one of the few blockchains that has gained popularity and mass adoption in a very short time. Solana's popularity is due to its energy-efficient and scalable ecosystem, as well as support for smart contracts. In addition, the network's superior infrastructure positions it as a major competitor to other similar blockchains such as Cardano and Ethereum, where Solana is known as one of Ethereum's top killers.
This article explores various aspects of the Solana ecosystem, how it compares to Ethereum, and some criticisms of Solana's working design.
What is Solana?
Solana is a permissionless open source blockchain that supports a high-speed and scalable system at minimal cost. The project uses an intuitive hybrid consensus protocol based on a single story proof algorithm and a special version of the proof game. So Solana claims a theoretical throughput of 65,000 to 71,000 transactions per second with almost no fees and without the help of an additional scaling solution.
Most importantly, Solana was built with smart contracts in mind, including non-fungible tokens (NFTs) and other decentralized applications (dApps). The network supports many DeFi platforms and decentralized markets.
The Solana blockchain was originally founded in 2017 by Anatoly Yakovenko along with Raj Gokal. After several testnet phases, the Solana mainnet was released to the public in 2020 with SOL tokens.
Understanding the Solana Ecosystem: How Does It Work?
Solana combines an innovative Proof-of-Story mechanism with Tower BFT and Proof-of-Play for scalability and consensus.
PoH works like a cryptographic clock, creating a digital record that confirms the sequence of transactions on the blockchain. This system is designed so that lock leaders can send transactions to all other validators in real-time, instead of passing them on after the entire block is complete. Transaction timestamps, which are the core of the history confirmation protocol, ensure that nodes can correctly order transactions into a block, even if they are not transmitted in chronological order.
In addition to PoH, Solana integrates a proof-of-concept mechanism where validators are chosen to validate and merge transactions into blocks based on their "shared" coins. Solana's cryptocurrency, SOL, is used for staking and is locked into the system to support blockchain functionality. Network members, on the other hand, are rewarded for verifying transactions and securing the Solana ecosystem.
Also note that the history confirmation protocol is also based on the Tower Byzantine Fault Tolerance (BFT) algorithm (an optimized version of practical BFT) when using a PoS mechanism. These three interrelated protocols work together to make the Solana network more secure and faster, with more TPS.
What features make Solana unique?
Solana stands out in the blockchain space for its proximity to smart contracts and low-cost, high-speed transactions.
The blockchain trilemma (decentralization, security and scalability) is the result of adopting a hybrid consensus mechanism, or more specifically, a proof-of-history protocol. The network focuses on scalability and sacrifices some of its decentralization. Solana achieves this with a PoS mechanism and master nodes that are selected based on timestamp transactions between nodes.
As a result, the Solana network can process more than 65,000 transactions per second, as each transaction costs only a fraction of a cent. On the contrary, some blockchains offer a high level of decentralization, but in return they mostly suffer from congestion or queuing issues as transactions take much longer to validate.
In addition, the Solana ecosystem allows investors to earn passive income by staking SOL coins. Stakeholders can also develop decentralized applications, blockchain-based games, create DeFi and NFT platforms and trade on the Solana blockchain.
SOL: Solana cryptography
Solana's cryptocurrency, SOL, is the network's native currency, securing it and acting as a medium of exchange.
As of October 12, 2022, the circulating supply of SOL is 357,458,896.29 SOL and the total supply is more than 511 million, which is not a maximum supply . Solana is one of the top 10 cryptocurrencies on CoinMarketCap with a market capitalization of over $11 trillion.
Solana vs Ethereum
Solana and Ethereum are often compared to each other due to their compatibility with smart contracts and DeFi. Although Ethereum leads the DeFi/dApps market with a TVL almost 95% higher than Solana, the latter is praised for its excellent transaction speed and performance. Solana can process over 65,000 transactions per second compared to 15-30 transactions per second for Ethereum. Also, Solana is very profitable with an average transaction fee of $0.00025, unlike Ethereum which distributes huge gas fees.
However, with the introduction of Ethereum Merge, the consensus protocol difference between the two platforms disappeared, as Ethereum now also works with a power-efficient PoS mechanism. Although Ethereum is on track to improve scalability and reduce gas fees, it is believed that the smart contract platform will not solve the scalability problem (through sharding) anytime soon, despite the massive upgrade.
Some criticisms of the Solana ecosystem
Solano has been criticized several times over the years; The most recent ones are based on hack attacks, Solana wallet security breaches and coin theft.
The most notable problems with Solana are the lack of transparency regarding the maximum amount of SOL (Solana's crypto) and the increasingly centralized design. Perhaps more than 50% of SOL tokens are owned by some experts and venture capital companies, while around 38% of the supply is reserved for the community only. Also, while there are more than 2,000 validators in the Solana ecosystem, more than a third of the total participation is concentrated in 25-30 validators. This approach aims to improve centralization where a relatively small number of nodes control the verification of more than a third of Solana's transactions.
Additionally, Solana regularly makes headlines for online attacks on her portfolio. In August, more than 7,500 wallets were hacked, from which the attackers withdrew millions of dollars in cryptocurrencies. Also in February 2022, about $320 million was stolen from the Wormhole. Additionally, the network was down for more than 17 hours last month due to an unusual spike in traffic.
However, the creators of Solana acknowledge the problems and explain that the blockchain is a beta version of the main network, so it will take time to completely eliminate all vulnerabilities. And despite the ups and downs, the Solana ecosystem is expanding rapidly, allowing crypto enthusiasts to take advantage of this low-cost, scalable smart contract platform.
