Solana Ecosystem Explained: A Guide To The Major Ethereum Killer
Solana is one of the few blockchains that has become famous and widely adopted in a very short period of time. Solana's popularity is due to its scalable and energy-efficient ecosystem, which is also compatible with smart contracts. Its excellent network infrastructure has positioned it as a major competitor against other similar blockchains such as Cardano and Ethereum, of which Solana is known as one of Ethereum's major killers.
This article covers different aspects of the Solana ecosystem, how it compares to Ethereum, and some design critiques of how Solana works.
What is Solana?
Solana is a permissionless open source blockchain that maintains a high-speed and scalable system while keeping costs to a minimum. The project adopts an intuitive hybrid consensus protocol based on a unique proof-of-stake algorithm and a unique proof-of-stake version. As a result, Solana claims theoretical performance of 65,000 to 71,000 transactions per second at almost no cost and without the help of additional scaling solutions.
Most importantly, Solana is structured to host smart contracts with non-fungible tokens (NFT) and other decentralized applications (dApps). The network supports multiple DeFi platforms and a decentralized market.
Solana Blockchain was originally founded in 2017 by Anatoly Yakovenko along with Raj Gokal. After several testnet phases, the Solana mainnet with the SOL token was launched to the public in 2020.
Understanding the Solana Ecosystem: How Does It Work?
Solana Tower combines BFT and an innovative proof-of-history mechanism with proof-of-stake for scalability and consensus.
PoH acts like a cryptographic clock and creates digital records that confirm the order of transactions on the blockchain. The system is designed to allow the block leader to forward transactions to all other validators in real-time instead of streaming after the entire block is complete. Transaction timestamps, which are at the core of the proof-of-history protocol, ensure that nodes can correctly sequence transactions within a block, even if the transactions are not published in chronological order.
In addition to PoH, Solana integrates a proof-of-concept mechanism where validators are selected to validate and add transactions to blocks based on their "stake" of coins. Solana's cryptocurrency, SOL, is used for staking purposes and is locked into the system to support blockchain functionality. Network participants are rewarded for validating transactions and keeping the Solana ecosystem secure.
Also, note that the Proof-of-History protocol uses the same PoS mechanism based on the Tower Byzantine Fault Tolerance (BFT) algorithm (the optimal version of utility BFT). These three interconnected protocols work together to make Solanar's network safer and faster with a higher TPS count.
What features make Solana unique?
Solana stands out in the blockchain space with its affinity for smart contracts and low-cost high-speed transactions.
Achieve blockchain's trilemma – decentralization, security and scalability – by adopting a hybrid consensus process or, more precisely, proof-of-history protocols. The network is mostly focused on the scalability domain at the expense of some of its decentralization. Solana achieves this through a PoS process and leader nodes are selected based on timestamped transactions between nodes.
As a result, the Solana network can handle more than 65,000 transactions per second, with the cost per transaction being only a fraction of a penny. On the other hand, some blockchains introduce a lot of decentralization, but instead they mainly experience bottlenecks or queues, as transactions take longer to verify.
Also, the Solana ecosystem allows investors to earn passive income by holding SOL coins. In addition, interested parties can develop decentralized applications, blockchain-based games, DeFi and NFT platforms for money and trade on the Solana blockchain.
SOL: Solana Cryptocurrency
Solana's crypto, SOL, is the network's native currency that maintains its security and acts as a medium of exchange.
As of October 12, 2022, the outstanding supply of SOL was 357,458,896.29 SOL and the total supply was over 511 million, which is not the maximum supply . Solana Crypto is currently among the top 10 cryptocurrencies on CoinMarketCap with a market cap of over $11 trillion.
Solana vs Ethereum
Solana and Ethereum are often compared to each other due to their smart contracts and DeFi compatibility. Although Ethereum dominates the DeFi/dApps market with about 95% more TVL than Solana, the latter is praised for its excellent transaction speed and performance. Solana can process transactions at 65,000 TPS compared to Ethereum's 15-30 TPS. Also, Solana is very cheap, with an average transaction fee of $0.00025, compared to Ethereum, which has high gas fees.
However, with the integration of Ethereum, the consensus protocol differences between the two platforms have disappeared, as Ethereum is supported by an energy-efficient PoS mechanism. Although Ethereum is in the process of increasing scalability and capping gas rates, it is believed that the smart contract platform will not solve scalability issues (through sharding) anytime soon despite major updates.
Some criticisms of the Solana ecosystem
Solana has drawn some criticism over the years; In the latest hacking attack, Solana relied on compromising wallet security and stealing coins.
Among the most important concerns about Solana are the lack of transparency of SOL's (Solana Crypto) maximum supply and its increasingly centralized design. Perhaps more than 50% of SOL tokens are owned by some insiders and venture capital firms, while about 38% of the shares are reserved for the community. Additionally, despite the more than 2,000 validations in the Solana ecosystem, more than a third of the growing interest is focused on 25–30 validations. This approach suggests better centralization, with a relatively small number of nodes controlling the verification of more than a third of Solana's transactions.
Also, Solana frequently appears in his portfolio about online attacks. As recently as August, more than 7,500 wallets were compromised where the bad guys made millions of dollars in cryptocurrency. About $320 million was stolen from the wormhole in February 2022. Also, the network was down for more than 17 hours last month due to an abnormal surge in traffic.
However, the creators of Solana acknowledged the problem and explained that the blockchain is a beta version of the main network, so it will take time to fully patch all the vulnerabilities. And despite the limitations, the Solana ecosystem is growing rapidly to allow cryptocurrency enthusiasts to take advantage of this scalable and low-cost smart contract compatible platform.
