What Is Solana? How Does It Work?

Solana is a new, high-performance blockchain for advanced enterprise applications. It’s a modular and versatile blockchain solution that can be deployed on-premise or in any cloud environment.

In this blog post, we’ll explain what Solana is, how it works, and why it’s an exciting development in the world of blockchain technology.

We see so many different use cases for blockchain emerging almost every day now. While most of these proposed solutions seem to involve tokens or other cryptoeconomics that are designed as incentives so that nodes perform actions they would not necessarily perform if there were no incentive (e.g., miners being incentivized with tokens to validate transactions), we are seeing more and more focus on performance as a priority.

What Is Solana?

Solana is a distributed ledger technology (DLT) built from the ground up with high performance in mind. The project was created by a team of top computer scientists and engineers who met at the Los Alamos National Laboratory, one of the most well-known research labs in the world.

Solana is designed to integrate easily with existing systems and to scale to meet the needs of the world’s most demanding industries, including financial services, health care, and supply chain management. Solana is based on three key innovations.

First, it uses a new consensus mechanism called “Proof of History” (PoH) that is provably more efficient than both Proof of Work and Proof of Stake.

Second, it uses sharding (a kind of parallelization) for scalability at the ledger level, allowing each node to perform the work of the entire distributed ledger.

Third, Solana uses the InterPlanetary File System (IPFS) as its data store, which has the added benefit of providing inter-system communication and decentralized file storage.

How Does Solana Work?

Solana consists of two main components:

Ledger: This is the immutable record of all transactions that have ever taken place. Solana’s ledger is a sharded (meaning it’s been “divided and distributed” across different servers) distributed database that uses IPFS as a data store.

Validator: This is the node that performs the verification of transactions and creates new blocks within the ledger. All nodes that participate in the Solana network run a full copy of the ledger. All nodes also perform the function of validators to create new blocks, but only a subset of the nodes are responsible for performing the consensus process.

At any given time, a few validators are selected to create new blocks, while the rest are in standby. This means that even if there are 1,000 nodes in the network, only a small subset is actively creating new blocks at any time. This means the ledger remains highly performant even with a large number of nodes.

Solana’s Biggest Innovation

Solana has achieved a number of important firsts in the blockchain space.

Solana is the first public distributed ledger project to use IPFS as its data store. While IPFS is often used for decentralized data storage, it has never been used as the data store for a public, permissionless blockchain.

Solana is also the first public blockchain project to use an algorithm called Proof of History for consensus, which provides the same level of security as Proof of Work algorithms (like Bitcoin) but is significantly more efficient.

This efficiency is crucial because, as the number of transactions on the ledger grows, the cost of computing the Proof of Work algorithms grows exponentially. Solana plans to scale to billions of transactions per second, which would make it one of the most efficient public blockchains in existence.

Why Is High-Performance Blockchain So Important?

When people think about blockchain, they usually imagine the world of cryptocurrencies like Bitcoin, in which people transact with one another using blockchain. But blockchain has many other applications. It can be used to improve supply chain management, to facilitate secure data sharing, to authenticate digital assets, and to integrate smart devices.

Blockchain technology could potentially transform every major industry. If blockchain is to reach its full potential, it must be able to sustain high transaction volume.

While Proof of Work has proven to be a secure and reliable way of reaching consensus when it comes to cryptocurrencies, it is not a sustainable solution for enterprise-grade blockchain applications. These use cases require consensus on a much larger scale.

Enterprise blockchains must process thousands of transactions simultaneously, often with strict compliance requirements for governance. The technology must be fast, scalable, and energy efficient.

What’s Next for Solana?

The team behind Solana has already built a working prototype of the blockchain. Over the next few months, they will be working to implement the full architecture and achieve full scalability.

In the longer term, the team plans to integrate Solana with other systems and to support interoperability with other blockchains.

The team has also announced a $100 million investment fund to support the development of Solana-powered applications. If you’re interested in using Solana, stay tuned for more information about the fund and how to apply.
