For instance, in May 2020, Solana Foundation permanently burned 11.4M SOL to “account for market-making activity.” Theoretically, this means that Solana has an unlimited supply. Since its mainnet came online, the total supply increased to 527M, making SOL an inflationary cryptocurrency. Since 2017, Solana Labs tapped software developers from Microsoft, Google, Qualcomm, and other tech giants to build its project. Through nine founding rounds, Solana has raised almost $336M, from venture capital firms, including Tor Kenz Capital, Alameda Research, Blockchange Ventures, and Multicoin Capital. Nevertheless, there is a chance that with PoS a group of validators will seize control.

After all, the network owner decides how many nodes there are, which limits the node verification speed bump. With public blockchains, this is not the case, as they are permissionless. Traditional payment networks such as Visa don’t have to worry about these problems because they are neither decentralized nor permissionless. This allows high network throughput and Visa executes up to 65,000 transactions per second vs. Ethereum’s 15 tps. It is a public blockchain network, which means that other users can access the blockchain to perform transactions.

Proof of Stake and the verifiable delay function

As a result, you can have a verifiable and transparent transaction sequence added by validators to a block. Without depending on a conventional timestamp, validators could check the time which has passed in the hashing process. The Solana blockchain platform has proposed a hybrid consensus mechanism that compromises on decentralization to maximize speed. The innovative combination of PoS and PoH makes Solana a unique project in the blockchain industry.

  • Solana looks like it’s going through the process of shaking out bugs to reach a high degree of stability based on the Proof of History concept.
  • Another programmer, Greg Fitzgerald, suggested he re-code the project using Rust, a programming language that Fitzgerald believed would offer increased productivity.
  • For illustrative purposes, imagine taking several pictures of a moving car.
  • Solana has a total supply of 511.6 million SOL tokens, 355 million of which have already entered the market.
  • The winner of these races gets to update the blockchain with the latest verified block of transactions, and in return receive a certain amount of crypto as a reward.
  • Another Solana advantage is the network’s extreme cost-effectiveness, as the project implements new tokenomics for lower fees.

Anyone on the network can become a Solana validator but doing so is still difficult because it requires a lot of computing resources. Solana is a highly functional open source project that implements a new, permissionless and high-speed layer-1 blockchain. The idea of running a network sporting billions in assets as a trial may raise a few eyebrows, but that’s Web3 for you. Solana looks like it’s going through the process of shaking out bugs to reach a high degree of stability based on the Proof of History concept. Cryptocurrency is created by code, and because it’s a non-physical currency, there needs to be validation in place to ensure that people don’t create or use the same coin twice. The process of making new cryptocurrency coins is known as mining and is often an energy-intensive, laborious process with some not-great environmental impact implications.

The Solana (SOL) token

Building on this progress, it continued its upward trajectory, eventually reaching a peak of approximately 500,000 TPS. This sustained growth paved the way for the project’s launch in early 2020, two years later. Even better, because the blockchain can be verified by a small piece of info, it means that it can be verified in parallel, or more than one piece can be verified at any given time. Most programmable blockchains can only validate a blockchain one at a time. Moreover, PoH can be considered as a high-frequency Verifiable Delay Function (VDF), a triple function (setup, evaluation, verification) to produce unique and reliable output.

Solana works on a Proof-of-Stake consensus model, which has been modified with eight new key innovations. The core innovation that underlays Solana is the Proof-of-History mechanism, which allows for the creation of historical records that prove that an event has occurred at a specific moment in time. Well, if you know the precise time, you can validate information a lot quicker. So on November 18th, 1883, American railroads adopted four time zones to standardize time across the United States. This article is part of a series that explains the core technical innovations behind Solana, the world’s most performant blockchain. Also, it is worth noting that Solana’s blockchain, while implementing one of the variations of PoS, is more eco-friendly and sustainable.

The History of Solana

For most blockchains, their throughput only applies to basic token transactions. For Solana, however, the 50,000 TPS capacity also applies to smart contracts. The virtual machines of Ethereum and EOS have runtimes that are single-threaded, which means that the blockchain state is only modified by one contract at a time.

SOL is the native coin of the Solana blockchain and is used to pay transaction fees within the network. SOL can also be staked with a validator to earn network fees and give holders the right to participate in protocol governance. The Solana project is built and supported by the Solana Foundation, based in Zug, Switzerland, and Solana Labs, located in San Francisco, California. When you need to move fast and process transactions as soon as possible, you need to be able to time in small units.

How Many Solana (SOL) Coins Are There In Circulation?

Short block times make transactions extremely fast and allow it to easily process thousands of transactions per second. Solana uses the Turbine protocol to transmit information in smaller pockets to nearby node clusters called neighborhoods. The time, in this case, is based on block height, which is simply the block number where the transaction is taking place.
