Rivaling, and perhaps even surpassing, the capabilities and applications of Ethereum, Solana emerges as a noteworthy blockchain in its own right. Its token, SOL, commands a significant stake in the cryptocurrency market, contributing to its widespread popularity and recognition among blockchain aficionados.

Designed for decentralized and scalable applications, Solana stands as a distinctive blockchain platform. In Geneva, the Solana Foundation currently oversees this open-source initiative that originated in 2017, with its blockchain infrastructure constructed by Solana Labs from San Francisco.
Despite the speed advantages in transaction processing and lower transaction fees compared to Ethereum, Solana’s cryptocurrency—also known as Solana (SOL)—witnessed a staggering increase of nearly 12,000% in 2021. Its market capitalization at one juncture exceeded $75 billion, establishing it as one of the most significant cryptocurrencies by this metric. By 2024, SOL retained this status among the leading cryptocurrencies in terms of market cap.
Before co-founding Solana, Anatoly Yakovenko gathered expertise in distributed systems design with leading tech giants, reportedly pushing the boundaries of transactions per second (TPS) to peaks of 65,000.
Overcoming the challenges of synchronization, Yakovenko’s proof-of-history (PoH) innovation allows each network node to depend on a verifiably documented passage of time.
Concept of Proof-of-History
Yakovenko shared a white paper in November 2017 that introduces the proof-of-history (PoH) framework. By validating time intervals between events, PoH helps the blockchain achieve consensus, incorporating these intervals into a ledger.
Within the white paper, Yakovenko highlights that existing public blockchains did not utilize unified time, with each network node relying on its internal clock, unaware of others. This lack of a standardized temporal reference often led to discrepancies when timestamps were used to accept or reject messages, as no uniform agreement among network participants existed.
Ethereum’s Enhancements
With a robust ecosystem, Ethereum holds a significant edge and ranks just after Bitcoin in market capitalization. Its 2022 advancements, merging the Beacon Chain with the Mainnet Chain, laid the groundwork for enhanced scalability, security, and sustainability. Future updates like danksharding are set to further reduce transaction times and alleviate network congestion. The impact of these innovations on Solana remains to be observed.
Solana’s Technological Framework
By leveraging algorithms to alleviate performance bottlenecks caused by blockchain software, Solana’s design achieves a blend of scalability, security, and decentralization. This architectural choice fuels speculation that Solana’s framework could potentially support up to 710,000 TPS on a regular gigabit network and up to 28.4 million TPS on a 40-gigabit network.
Functioning on a dual consensus model of proof-of-history (PoH) and proof-of-stake (PoS), Solana’s blockchain allows validators—those who verify transactions—to do so based on their coin or token holdings, with PoH facilitating rapid timestamping and verification.
Solana’s expansive ecosystem and versatility have naturally drawn parallels to Ethereum, the principal blockchain for NFTs. Solana and Ethereum share a proof-of-stake (PoS) consensus mechanism where validators stake their cryptocurrency as collateral, earning rewards for their participation. PoH is Solana’s enhancement to PoS. Buzz surrounding Solana in 2021 was fueled by its distinct superiority over Ethereum in terms of transaction processing speed and costs. On September 18, 2024, Solana handled more than 2,400 transactions per second, with average transaction costs of $0.00026. In stark contrast, Ethereum processes fewer than 15 TPS, with fees averaging around $0.30.
