What is Solana (SOL)?

In this article, we go in depth about what Solana is and how it works. Solana is a decentralized blockchain and a cryptocurrency.

You can easily both buy and sell Solana at Firi.

Solana is a decentralized blockchain that is programmable. That is, you can build smart contracts and decentralized apps on the blockchain, which makes Solana one of Ethereum's clear contenders. Solana is an open source project, and the blockchain is designed specifically to offer scalable, decentralized apps and smart contracts. Solana also offers support for NFTs.

Solana themselves claim that they are the world's fastest blockchain, and with up to 65,000 transactions per second, you should not ignore that they are absolutely right. In comparison, Ethereum can carry out 15 transactions per second, while Bitcoin can carry out between four and seven transactions. Furthermore, the transaction costs of Solana are low, at least if we compare it to their rivals, such as Ethereum. This comes from the network's good scalability.

Solana's cryptocurrency is called Solana, but is also known under the ticker SOL. Solana is one of the world's largest cryptocurrencies based on market capitalization.

Firi Explains: What is a blockchain and what is Proof of History?

In 2017, Solana's co-founder, Anatoly Yakovenko, published a white paper describing the innovative concept of Proof of History (PoH), which is one of the technologies Solana's blockchain uses. But what is Proof of History?

Well, it's time. In short, it is a technique that can cryptographically verify the time and order between two events. This is recorded on the digital ledger. But first let's take two steps back and look at what a blockchain actually is.

A blockchain is simply explained as a database containing data, which is secured through a distributed network of participants. A database is a collection of information. This data is stored in blocks, and each block of data is linked together and forms a chain - i.e. a blockchain. The most common data in a blockchain is transactions.

Instead of a central actor being responsible for storing the data, the majority of blockchains are secured using cryptography and through a decentralized network of people around the world. An important factor that distinguishes blockchains from ordinary databases is that the information in a blockchain cannot be manipulated or changed.

Bitcoin and Ethereum currently use Proof of Work (PoW) to verify transactions, but Ethereum is transitioning to Proof of Stake. Solana uses Proof of Stake (PoS) in addition to Proof of History. One of the main challenges of the Proof of Work algorithm is precisely the timing and sequence of transactions. Computers will always use a centralized clock to check that their own clocks are correct, but what do you do in decentralized systems? How can one validate information without a central clock? Solana will solve this problem with its Proof of History technology.

Proof of History is a proof of time - a measurement of time. This system allows all the different parts of Solana to coordinate events that occur on the network without the need for a centralized clock. This time measurement is compared to the function of an old water clock which measures how much time has passed. In such a water clock, time was measured by allowing water to flow through a vessel in a controlled manner, and then measuring the amount of water. Similarly, the Proof of History system measures how much time passes between each activity or task in the network. For this, they use what is called a verifiable delay function (verifiable delay function) which cryptographically measures this time in the block chain.

We will explain Proof of History in more detail in an upcoming chapter of this article, and in the meantime, we recommend reading this article from Solana if you want to delve deeper into this exciting technology.

Who made Solana and what is the back story?

Solana took the entire crypto industry by storm in 2021 when SOL was among the cryptocurrencies that saw explosive price growth. With a percentage increase of over 35,000 percent from its all-time low in 2020, Solana marked itself out as a strong competitor to the existing major cryptocurrencies, quickly finding its way into the top 10 list of the world's largest cryptocurrencies by market capitalization.

These are important events in Solana's history:

2017:
As mentioned, Solana's co-founder Anatoly Yakovenko published a white paper describing Proof of History, the core of Solana, in 2017.

Yakovenko then recruited Greg Fitzgerald and Stephen Akridge, with whom he worked previously at the leading technology company Qualcomm Incorporated, and three other people, to co-found the company Loom. It turned out that an Ethereum-based project had a similar name, and to avoid being confused with them, Yakovenko and the gang changed the name of their project to Solana.

2018:

In February 2018, Fitzgerald started work on creating prototypes for the open source implementation of Yakovenko's white paper. The project was published on GitHub under the name Silk. On March 28, the team created the Solana GitHub organization and renamed the prototype Silk to Solana.

In June 2018, they scaled up the project to run on cloud-based networks, and a month later the company published a testnet that supported up to 250,000 transactions per second. The network consisted of 50 nodes. Later this year, they published a testnet running on 150 nodes and up to 500,000 transactions per second. Still, the average was 200,000 transactions per second.

Solana Labs also started raising money to build its new crypto network this year.

2019:

Between April 2018 and July 2019, the Solana team raised just over $20 million in various private token sales.

2020:

In 2020, Solana launched its first public test network, Tour de SOL, and eventually also the main network in beta.

2021:

Solana's main network, or Mainnet, was launched in 2021 and since then the ecosystem has grown at a high rate.

A Bloomberg journalist described Solana as "a potential long-term rival to Ethereum", referring to Solana's extraordinary transaction speed and low transaction costs.

Furthermore, in September 2021, the Solana blockchain went offline after reaching 400,000 transactions per second. Due to high demand, the network "forked", i.e. the blockchain split, after receiving help from its validator community.

In December 2021, Melania Trump announced that she will use Solana to launch an NFT.

The collapse of FTX

Since Solana was backed by Sam Bankman Fried and FTX, the dramatic collapse naturally extended to Solana as players, including FTX and Alameda research itself, sold large amounts of Solana to raise cash for the ongoing liquidity crisis at FTX. It is important to understand that Solana is a decentralized blockchain and cannot go "bankrupt" like a centralized exchange, but there is no doubt that Solana has suffered a severe setback and that the ecosystem has been negatively affected by the FTX chaos, especially because the link to FTX creates great uncertainty and negative associations, in addition to the fact that companies in the FTX system with assets in Solana could be forced to sell these. Only time will tell what Solana's future as a cryptocurrency and ecosystem looks like.

How does Solana work?

How does Solana work?

Solana is a programmable blockchain. This means developers can build decentralized apps and smart contracts on the protocol. We recognize this from Ethereum. Solana's architecture aims to demonstrate that it is possible to avoid the classic bottlenecks encountered by previous generations of blockchains, such as Bitcoin and Ethereum. This applies, among other things, to low transaction speed and high transaction fees when the amount is high. The way Solana will solve this is by using both Proof of Stake consensus to validate blocks and its own Proof of History technology.

Solana claims they have the world's fastest growing ecosystem. This ecosystem refers to a number of technologies that work synergistically with the Solana protocol to increase speed and scalability. The ecosystem also includes a number of dApps (decentralized applications) that are built on Solana's blockchain. Developers can build on this ecosystem, thanks to the open source code of Solana.

Validators at Solana

Another factor that differentiates Solana from the competition is that it is easy to become a validator. A validator is someone who is responsible for verifying transactions on a blockchain and these are often rewarded in the form of payments in the representative token. On some blockchains the barrier to being a validator is very high, for example on Ethereum one must stake at least 32 ETH to become a solo validator. On Solana, however, there are no minimum requirements to become a validator when it comes to tokens. You can therefore become a validator with a small number of SOL tokens, but the difference is that the computer required to be a validator is something out of the ordinary. According to Solana, a full 128GB of RAM and at least 12 CPU cores are required.

Challenges for Solana

Like all other blockchains, Solana has certain challenges. In the blockchain world, the so-called "blockchain trilemma" is often the biggest problem developers face. The concept was first discussed by Ethereum co-founder Vitalik Buterin and describes three challenges that developers face when building blockchains: decentralization, security and scalability.

In the process of developing a blockchain, a trade-off occurs where developers generally have to sacrifice one of the three aspects in favor of the other two. As mentioned, Solana tries to solve this trilemma, yet decentralization is largely sacrificed to maximize scalability and security.

Despite the fact that it is exactly scaling that Solana has focused on, the blockchain constantly experiences problems related to this and decentralization. In January 2022, the blockchain experienced network outages as many as six times as a result of network overload. Whether this is negative or positive will be a subjective clarification, as one can argue that the use of the network and developer activity testify to an attractive platform for developers and users.

What differenciates Solana from Ethereum?

These are the similarities between Ethereum and Solana:

  • Both blockchains are programmable. Despite Solana's growing popularity, Ethereum is still the leading blockchain for decentralized apps
  • Both blockchains facilitate smart contracts
  • Both blockchains lay the foundation for decentralized finance
  • Both blockchains support NFTs

These are the differences between Ethereum and Solana:

  • Ethereum uses Proof of Work consensus to verify transactions. They are in the process of transitioning to Proof of Stake. Solana uses Proof of Stake and makes use of its own technology called Proof of History
  • Ethereum is more decentralized and stable than Solana. The Ethereum network consists of over 350,000 nodes, while Solana consists of just over 1,700 nodes. The more nodes there are, the more decentralized the network is likely to be
  • Solana can theoretically handle 65,000 transactions per second, while Ethereum can only handle 15
  • Solana's transaction cost is much lower than Ethereum's
