Solana has demonstrated remarkable resilience, steadily recovering from past market events. Its ecosystem continues to thrive, largely due to its innovative Proof of History (PoH) mechanism, which positions it as a leading high-performance blockchain. This technology allows Solana to approach the theoretical limits of transactions per second (TPS) for a single-shard blockchain. The network has also introduced several technical updates, providing targeted solutions to security concerns and showcasing a strong commitment to safety, ongoing development, and long-term sustainability. This article explores the core network parameters that define and power the Solana blockchain.
What Are Solana’s Core Network Parameters?
Solana is a high-performance blockchain network. Its key network parameters encompass its consensus algorithm, block time, transaction confirmation speed, block rewards, and the various participants that maintain the network. These elements work in concert to achieve its renowned speed and scalability.
Proof of History (PoH): The Innovative Timekeeper
Proof of History is Solana's foundational innovation. It is a globally available, permissionless clock that provides a cryptographic record of time passage. Crucially, PoH is not a consensus mechanism itself. Instead, it operates alongside the consensus layer, which uses a delegated Proof-of-Stake (PoS) model combined with elements of Practical Byzantine Fault Tolerance (PBFT). The primary role of PoH is to solve the problem of accurately timestamping transactions on a high-throughput blockchain.
This becomes essential due to Solana's Turbine protocol, where a leader node breaks a stream of transactions into smaller pieces to be broadcasted. PoH provides a mechanism to easily order these events and reassemble the original sequence, ensuring data integrity without bottlenecks.
Achieving Speed: Turbine and Gulf Stream
Solana's incredible throughput is primarily due to its fast and reliable synchronization. The PoH algorithm allows a leader node to generate a cryptographic proof that a certain amount of time has passed since the last confirmation. This proves that all data hashed into that proof must have occurred before it. The node then shares the new block with validator nodes, which can instantly verify this proof.
A key advantage is that blocks can arrive at validators in any order, even significantly delayed, without compromising security. This reliable synchronization allows Solana to break blocks into smaller batches of transactions called "entries." These entries are streamed to validators in real-time, before consensus is formally reached. Technically, Solana doesn’t "send blocks" in the traditional sense; validators vote on entries, leading to confirmation. This architecture enables Solana to achieve a confirmation time of approximately 800 milliseconds.
Network Participants and Incentives
A decentralized network requires various actors to function:
- Validators: These nodes are responsible for verifying transactions and producing new blocks. They participate in the consensus process and are incentivized with SOL token rewards for securing the network.
- RPC Nodes: These nodes (often referred to as Full Nodes) store a complete copy of the blockchain and serve data to applications and users.
- Developers and Users: Individuals and organizations that build and interact with decentralized applications (dApps) on the Solana network.
This ecosystem is secured by rewarding validators with SOL tokens, which incentivizes honest participation and investment in network infrastructure.

What is Solana?
Solana is a powerful, open-source project that implements a new, permissionless, and high-speed layer-1 blockchain. It was founded in 2017 by Anatoly Yakovenko, a former executive at Qualcomm, with the goal of scaling throughput beyond levels achieved by most popular blockchains while maintaining low costs.
Solana employs an innovative hybrid consensus model. It combines its unique Proof of History (PoH) algorithm with a lightning-fast synchronization engine, which is a variant of Proof-of-Stake (PoS). This architecture allows the Solana network to theoretically handle over 710,000 transactions per second (TPS) without needing secondary scaling solutions like sharding or layer-2 networks.
The project's third-generation blockchain architecture is designed to facilitate the creation of smart contracts and decentralized applications (DApps). It supports a wide range of decentralized finance (DeFi) platforms, non-fungible token (NFT) marketplaces, and other Web3 services.
After its inception during the 2017 blockchain boom, Solana progressed through an internal testnet in 2018, followed by several public testnet phases, culminating in the official launch of its main network (mainnet) in 2020.
Frequently Asked Questions
What makes Solana so fast compared to other blockchains?
Solana's speed stems from its innovative Proof of History (PoH) consensus. PoH acts as a cryptographic clock that timestamps transactions before they are batched into a block. This eliminates the significant overhead of traditional blockchains where nodes spend time communicating to agree on time and transaction order, allowing validators to process transactions in parallel at incredible speeds.
Is Solana more centralized than Ethereum?
This is a common topic of discussion. Solana's high hardware requirements for running a validator node can lead to a smaller number of validators compared to networks like Ethereum. While this can be perceived as a step towards centralization, the network is still permissionless and decentralized in its operation. The trade-off is made for achieving higher throughput and lower transaction costs.
What is the SOL token used for?
The SOL token is the native cryptocurrency of the Solana network. It has three primary uses: paying for transaction fees and computational services (gas), participating in governance through staking, and as a medium of exchange within the Solana ecosystem for trading NFTs or transacting in dApps.
What are the main security features of the Solana network?
Solana's security is based on its delegated Proof-of-Stake (PoS) consensus, where stakeholders choose validators to secure the network. Its innovative Proof of History (PoH) also adds security by making it computationally infeasible to alter the order of transactions. The network continues to undergo rigorous audits and updates to enhance its security posture.
Can Solana really handle 65,000 TPS?
The 65,000 TPS figure is a theoretical maximum under ideal laboratory conditions. In practice, on the live mainnet, the sustained TPS is lower but still significantly higher than most other blockchains. Real-world performance depends on network demand, hardware capabilities of validators, and the complexity of the transactions being processed.
How does staking work on Solana?
Users can stake their SOL tokens by delegating them to a validator of their choice. This helps secure the network. In return, stakers earn a portion of the rewards that the validator receives for processing transactions and creating blocks. Staking is non-custodial, meaning users retain ownership of their tokens while they are delegated.

Conclusion
Solana was designed from its inception to be a high-performance blockchain. Its modified version of Proof-of-Stake, enhanced by Proof of History (PoH), was explicitly revised for superior performance. The goal was to ensure the network remains competitive, even with the advent of other advanced blockchain solutions. While some purists may debate its level of decentralization, Solana's approach has found a significant market fit. In the vast blockchain landscape, different networks offer various trade-offs, catering to diverse audiences and enabling a wide array of innovative applications.
