Cardano vs Solana: Which One is Better for the Future?

Cardano is a third-generation blockchain protocol that enables the creation of a Decentralized Finance (DeFi) ecosystem. While it shares some similarities with Solana, such as developers being able to create custom applications for their users, it is distinct in that it is based on the Ouroboros consensus mechanism, which is backed by peer-reviewed research. However, Solana has gained more traction due to its much higher transaction throughput, even though Cardano is an extremely capable protocol.
It's time to take a closer look at the distinction between blockchain protocols! In this article, we'll explore the unique features of each and gain a better understanding of what sets them apart.

What Is Cardano?

Charles Hoskinson, the co-founder of Ethereum, founded Input Output (IOHK) in 2015, a blockchain research company, with the mission of developing infrastructural solutions for public and private clients. He and Jeremy Wood co-led the development of one of IOHK’s projects, Cardano, which utilizes a technique known as RINA (Recursive InterNetwork Architecture). This allows Cardano to increase its transactional throughput by splitting the main network into subnetworks that communicate with each other.

What Are the Features of Cardano?

• Ouroboros consensus mechanism: The Cardano Foundation's Ouroboros consensus mechanism is a verification system that allows users to stake their ADA (the native token of the Cardano ecosystem) and take part in the transaction validation process. Unlike PoS, users are only required to stake their ADA at the time of the network "snapshot" and can move their staked ADA around and participate in DeFi activities before and after the snapshot. This is in contrast to PoS, where staked coins can only be withdrawn after the unbinding period has expired.
• Programmability: The Alonzo hard fork, completed just years ago, brought programmability to Cardano, a feature that had been lacking until then. This has sparked a renewed interest in the blockchain, as people now recognize its potential for more than just transferring value from one point to another. With the addition of smart contracts, users can now make use of a wide range of possibilities.
• Transparent and Traceable: One of the biggest changes to the Cardano protocol is the division of its base layer into two separate components – the Cardano Settlement Layer (CSL) and the Cardano Computation Layer (CCL). This split is designed to add an extra layer of understanding to the purpose of transactions, making the blockchain more transparent and traceable.

Despite the Cardano's groundbreaking status as a peer-researched and built blockchain, it has faced some issues, such as prolonged upgrades. This has caused delays in the project's overall implementation. The inclusion of smart contracts functionality, even though there are many blockchain protocols that already offer this, has raised questions about Cardano's place in the larger blockchain ecosystem.

What Is Solana?

Solana is a Layer 1 blockchain protocol that uses Proof of History (PoH) as its consensus mechanism. It focuses on validating the time difference between two events on the blockchain, which allows for high transaction throughput of up to 100,000 transactions per second without needing Layer-2 scaling solutions. This surpasses the 50,000 transactions per second that are easily achievable at the base layer of the blockchain.

What Are the Main Features of Solana?

• PoH: Proof of History (PoH) is a consensus method that combines the time of a transaction with Proof of Stake to process said transaction. This time is determined by the block height, which is the block number in which the transaction takes place. By being used in conjunction with a Verifiable Delay Function algorithm, the blockchain is able to securely timestamp events. Each node is able to add blocks without agreeing with the other nodes, instead opting to agree to the PoH timestamp. With PoH, Solana has a synchronized clock for their entire blockchain. Validators can use PoH to replay events within the blockchain, allowing for extremely fast transaction speeds, with the potential of up to 50,000 TPS.
• Horizontal Scaling: Solana innovates with horizontal scaling, allowing it to distribute computing resources by adding multiple computers to its processing network. This enables tasks to be processed in parallel, maximizing the use of distributed resources.
• Layered services: Solana's technology stack is comprised of various services layered on top of the network that work together to improve efficiency. This allows developers to create decentralized applications (Dapps) and Decentralized Financial Institutions (DeFis) on the platform. Solana's DeFi ecosystem has been growing rapidly, with over 200 projects already in existence and many more in the works. Its high transactional throughput has enabled this growth, outpacing the DeFi ecosystem on Cardano.

Cardano vs Solana: Which One is Better for the Future?

Solana's fast transaction speed has made it popular, but Cardano stands out for its innovative Proof of Stake validation system. Neither Cardano nor Ethereum has been able to surpass Solana's transaction speed yet. However, Since its debut, the Solana network has suffered through more than six outages, leaving users with transaction backlogs. Following the 17-hour outage that necessitated the assistance of engineers and over 100 validators, analysts suggest that the Solana team prioritized scalability over security.

Despite the fact that Cardano has been focused on decentralization and has shown capability as a blockchain, it has yet to make a splash in the ecosystem as Solana has. Solana has conducted multiple hackathons to draw in developers and users to its platform, and Cardano also has plans to grow its DeFi ecosystem. But, Solana's advantage of providing high transaction throughput at a lower cost has made it the preferred option in the space. This could still change, however.

When coming back to the question, Cardano and Solana, which one is better? Although Solana and Cardano have a similar roadmap, their approaches differ; Cardano is striving for a scalable and completely decentralized network managed by the community, while Solana offers users rapid transactions (unparalleled within the crypto space) with low fees and a semi-decentralized network. Both of these projects are ambitious and have an expanding following, giving users the option between steadiness and fast transactions.
