What is Solana is answered most directly by its design: a proof-of-stake Layer 1 blockchain that uses a timekeeping method called Proof of History to process transactions in parallel at low cost. Solana is the network's native token, SOL.
Core technology and blockchain architecture
Proof of History is a sequence of hashes that proves that data existed before a given point and that a set amount of time passed between events. Tower BFT, a PBFT-derived consensus algorithm, uses this sequence as a global clock before consensus (Solana Terminology; Solana Migration Guide).
Other components of the original design include Turbine, which propagates blocks across validators in layers, Gulf Stream, which forwards transactions to the next expected leader, and Sealevel, a parallel smart contract runtime (Pipelining in Solana; Ackee Solana Book).
Validator software is now multi-client. It includes Agave, Jito-Solana, Firedancer (C++), sig (Zig), and the original Solana Labs client. Firedancer, built primarily by Jump Crypto, went live on mainnet on 12 December 2025 (The Block).
Who is behind Solana and where is it based?
Anatoly Yakovenko, a former Qualcomm engineer, conceived Solana and created Proof of History. He is described as co-founder and CEO of Solana Labs. Greg Fitzgerald, Stephen Akridge and Raj Gokal are also named as founders or early key people (Ledger; Messari).
Sources differ on the whitepaper date, placing it in November 2017 or February 2018. Solana Labs, Inc. was formed in Delaware in March 2018 according to Messari. Mainnet Beta launched in March 2020. On 8 April 2020, Solana Labs transferred its intellectual property and most of its assets, including SOL tokens, to the Solana Foundation (Solana).
The Solana Foundation is a Swiss non-profit registered under CHE-436.843.713, with a registered address in Zug. Cryptoeconomics says it has been seated in Zug since September 2021, while Bloomberg's LEI record gives an entity creation date of 19 August 2019 (Bloomberg LEI; Cryptoeconomics).
Anza, launched on 30 January 2024 by former Solana Labs executives and core engineers, forked the validator as Agave. Its legal entity was not confirmed in the sources. Development is distributed, and the sources do not identify a single operating country beyond US associations, including a San Francisco address listed for Solana Labs on LinkedIn (Anza).
Primary use cases and real-world applications
Activity centres on decentralised finance, payments, consumer apps and token trading. On 28 August 2026, DefiLlama data cited by StealthEX showed Solana DeFi total value locked at $5.917 billion and 24-hour DEX volume at $3.485 billion. Grayscale Research reported on 30 June 2026 that Solana hosts more than 1,000 independent applications and averages over 100 million transactions per day (StealthEX; Odaily).
Tokenomics
CoinStats market data shows a price of $95.47, a 24-hour change of -0.87%, a market cap of $56.34B (rank #7) and 24-hour volume of $1.77B. Circulating supply is 590,094,958 SOL and total supply is 636,761,038 SOL. The all-time high is $293.31, and the current price is 67.45% below it.
Genesis supply was 500 million SOL. Fidelity Digital Assets lists the initial allocation as follows (Fidelity Digital Assets):
| Allocation | Amount (SOL) | Share | |
|---|---|---|---|
| Community Reserve | 194.5M | 39% | |
| Seed Round Investors | 81.2M | 16% | |
| Founding Sale | 64.6M | 13% | |
| Founding Team | 63.9M | 13% | |
| Solana Foundation | 52.3M | 10% |
Inflation began at 8% with a disinflation rate of 15% per year and a long-term rate of 1.5% (Solana Staking). Inflation was 3.82% as of 1 June 2026 (Helius).
Validators approved SGP-0002, which implements SIMD-0550, on 28 August 2026 with 67% of participating stake. It doubles the disinflation rate to 30%. Galaxy projects issuance will fall by about 18.9 million SOL over six years, and the 1.5% floor will be reached in 2029 instead of 2032 (Galaxy).
Each transaction pays a base fee of 5,000 lamports per signature, with 50% burned and 50% paid to the block-producing validator (Solana Fee Structure). Under SIMD-0096, 100% of priority fees go to validators, so none are burned (SIMD-0096). Staking estimates differ by tracker and date. Datawallet reports about 68.9% of supply staked (Datawallet).
Consensus and network security model
Solana combines proof of stake with Proof of History for ordering. Cryptoticker counted 656 active validators and 20 delinquent validators in October 2026 (Cryptoticker). The validator count was 795 in January 2026, down 68% from a peak of 2,560 in March 2023 (Cointelegraph).
The Nakamoto coefficient was 31 in March 2023 and 20 in January 2026. The decline reflects the smaller validator set. As of 13 October 2026, about 15.8% of stake among the top 500 validators used Firedancer-family clients (OrbitFlare).
The last full-cluster outage occurred on 6 February 2024 and lasted about five hours. It was resolved by upgrading to v1.17.20 and restarting the cluster (Protos).
Partnerships and ecosystem integrations
- Payments: Visa settles USDC on Solana and expanded Solana settlement to more card acquirers in Q2 2026 (Stablecoin Insider). PayPal's PYUSD is issued natively on Solana.
- Stablecoins: Open USD (OUSD) went live on Solana on 30 September 2026. Its five founding partners are Coinbase, Mastercard, Shopify, Stripe and Visa (Solana Compass). Western Union's USDPT launched on Solana on 4 May 2026.
- Enterprise: Worldpay and Western Union signed on to the Solana Developer Platform, launched on 11 June 2026 (Solana Compass).
- ETFs: NerdWallet, updated 28 October 2026, reports eight spot Solana ETFs actively trading (NerdWallet).
Competitive advantages and unique value proposition
Solana's main advantages are high throughput, low transaction fees, fast confirmation and a single shared state that simplifies composability between applications. Its design aims to make onchain interactions feel closer to conventional internet applications. The post-Alpenglow finality target of about 150 milliseconds is a design target from Anza and has not been independently measured in the sources reviewed.
Development activity and roadmap
Alpenglow activated on mainnet at the start of epoch 1064 on 21 October 2026, at approximately 13:36 UTC. Its Votor component replaces TowerBFT for voting and finality, with a target of roughly 150 milliseconds compared with about 12.8 seconds before. Rotor, a planned replacement for Turbine, is not yet scheduled (Solana Foundation).
Agave 4.4 is planned for November 2026 and Agave 4.5 for December 2026 (Solana Upgrades). Developer counts depend on methodology. Electric Capital cited 901 full-time developers in May 2026, up 35% year over year, while Artemis reported 942 weekly active developers in March 2026, down 40% over three months (Startup Fortune; CoinDesk).
