Introduction

Solana (CRYPTO:SOL) is a blockchain platform known for its speed and efficiency. SOL tokens are its native cryptocurrency and are used to pay its transaction fees. Since launching in 2017, Solana has grown to become one of the largest cryptocurrencies in the world. Because the Solana blockchain has smart contract capability, developers can use it to build decentralized apps (dApps). Its strong growth has helped establish it as a rival to other major programmable blockchains, including Ethereum (CRYPTO:ETH) and Cardano (CRYPTO:ADA). Solana is in a competitive marketplace, but there are several reasons to be bullish on it. Read on for a detailed guide to Solana to learn more and decide if you should invest.

The biggest draws of Solana are its fast and cheap transactions. It's reportedly able to handle 65,000 transactions per second, and the average cost per transaction is $0.00025. Solana is able to do that because it uses proof of history, a unique algorithm to validate transactions. Most blockchains use either a proof-of-work or proof-of-stake consensus mechanism, with proof of stake being the more efficient option. Solana uses a hybrid protocol that combines proof of stake with proof of history for even faster processing. As far as what Solana does, it's an open-source blockchain, which means that developers can use it in a variety of ways. Here are a few examples of what can be done on the Solana ecosystem: Minting, selling, and trading non-fungible tokens (NFTs). Developing decentralized finance (DeFi) platforms, such as decentralized crypto exchanges. Building blockchain games, including Web3 games, and partnerships with big-name companies such as FTX, Lightspeed (NYSE:LSPD), and Forte. One of the most exciting developments with Solana has been Solana Pay, a free-to-use payments framework. It allows merchants to accept payments directly from customers through the Solana network. Payments are made in stablecoins such as USD Coin (CRYPTO:USDC) that are designed to maintain a stable price. By using Solana Pay, businesses can avoid high payment processing fees.

Serum is a decentralized exchange software built on Solana where cryptocurrencies can be bought and sold by traders. If you’re unfamiliar, Solana is a blockchain platform that aims to increase user scalability through faster transaction settlement times. By being deployed on Solana, Serum can fully benefit from the speed and cost effectiveness of transactions settled on its blockchain. Central to Serum’s design is a decentralized orderbook run by smart contracts that aims to mirror traditional exchanges by matching buyers and sellers. This gives participants flexibility with pricing and order sizes when they submit orders to Serum, giving them full control over their trading. In this way, Serum is intended to operate a new kind of decentralized exchange that intends to rival those built using an automated market maker (AMM) such as Uniswap, Sushi and Bancor. Further, Serum offers cross-chain support, meaning that traders can trade tokens built on other platforms like Ethereum or Polkadot. Existing decentralized finance (DeFi) projects can also access Serum’s features and liquidity, regardless of which blockchain they are built on. Serum’s utility token, SRM, enables holders to receive up to a 50 percent discount on their trade fees and stakers to vote and participate in the platform’s governance mechanism. Those wishing to stay connected on the currency development of Serum can bookmark its blog for up-to-date details. [] []

Methodology

The following tables in this dashboard are employed in order to obtain data:

• solana.core.fact_events
• solana.fact_swaps
• solana.core.fact_transfers
• solana.core.fact_transactions
• solana.core.dim_labels
• solana.core.fact_swaps
• solana.core.fact_stake_pool_actions

Aim of this analysis:

This dashboard aims to investigate the OpenBook success in tractions after the replacement of Serum and the response of the Solana DeFi to the risks presented by serum. It must be notified that the need to replacing serum was one of the aftereffects of the FTX/Alameda collapse for Solana. FTX/Alameda collapsed on 8 Nov, therefore two period before and after 8 Nov has been considered for before and after FTX/Alameda collapse, respectively. It is worth mentioning that OpenBook launched on 12th November. This investigation is carried out for a period of the 1st of the Nov to the present time.
