Rebuilt for Scale

Lightning-fast distributed ledger technology for mission-critical decentralized apps.

710,000 tx/s with off-the-shelf hardware and no sharding.

Proof of History: The Key to Speed

  • Similar to Google’s TrueTime, which relies on synchronized atomic clocks for a trusted source of time and ordering, Solana has created a cryptographically secure and trustless time source--and built a blockchain around it. We call it Proof of History.
  • By weaving this standardized timestamp into the blockchain, nodes in the network can verify the time and order of events without witnessing them directly. This drastically reduces messaging overhead and is one example of the many optimization capabilities that become available through Solana’s Proof of History.

Sub-second finality that actually scales

  • Decentralized blockchain solutions have a scaling problem. In addition to low transaction rates, maintaining quick finality while the network scales is a major problem and many current solutions compromise decentralisation.
  • Through Solana’s “Avalanche” network communication innovation, finality times reduce exponentially as the network grows. This means we can expect ~500ms finality up through 10s of thousands of nodes and beyond.

Finally, scaling without sharding

  • Solana’s approach takes existing blockchain architecture and algorithms and improves on them instead of overlaying additional complexities such as sharding which can compromise security. We believe the right solution is a simple solution.

Scalable smart contracts in any language

  • The development community is our top priority. We intend to be the go-to network for developers who want to build decentralised applications of any kind. With Solana, you can write smart contracts in almost any language. We leverage Berkeley Packet Filter, allowing any language that LLVM supports to be utilized.
  • In addition, the smart contracts engine runs on GPUs. The future is massively parallel, and GPU cores are doubling every 2 years. Today a 5 thousand dollar machine will simultaneously execute 14,000 smart contracts. In two years 28,000. This is why in 10 years solana will be the first blockchain to process a billion transactions per second.

(Some) Use Cases

Decentralized exchanges

Imagine a decentralized trading system that never touches users’ private keys. The entire order book is securely included in the blockchain replicated state while retaining all the performance characteristics of Nasdaq. At 710k tps, Solana can fit Nasdaq's volumes with room to spare. We enable this using atomic cross chain transactions combined with tradable swaps.


Payments are the holy grail of blockchain, but adoption and scalability are inevitable hurdles. Solana's transaction costs are to be on the order of $0.000001 and lightning fast. Bitcoin's throughput, at 3 payments per day per person, is only enough to service the population of Berkeley, California. We can do better. Solana lays the foundation for the payments platform that blockchain has always promised.

Distributed Web Services and Storage

The future of cloud storage and web services can be decentralized, encrypted, permissionless, and secure. Decentralized file storage systems have the potential to eliminate high markup and human capital costs, and set new standards of unit economics for distributed data storage. Solana provides a scalable path for this future to become a reality.

Distributed Ad Exchanges

If ads are traded on a single, transparent platform, all sorts of ancillary data-driven industries can sprout up: tracking and measurement, rating, and industry reporting. These business models would require nodes to keep much more extensive ledgers than just day-of transactions. At the same time so we need a highly scalable chain to support this future of ad tech (Google serves up 340,000 ads per second). What distributed solutions are there that can support high speed on-chain data collection? You guessed it, this is where Solana’s high throughput blockchain shines.
