Algorand vs. Cardano

Every day or the other, we have heard about the talks of certain businesses getting digitized, and many of them look forward to Blockchain development services. When we talk about solving the problems through Blockchain, we just set our eyes on the most used platform, Ethereum Blockchain, rather than looking for the most efficient and suitable platform for a certain business.

Currently, there are many Blockchain platforms in the fray, but today we will be discussing those two platforms that are working to solve the problems faced by the Blockchain world – Algorand and Cardano.

What Is Algorand?

Algorand is an open-source Blockchain protocol released in 2017 and is making itself into the news due to its high appreciation. It is simple and fast for developers to work upon Algorand as its unique combination of open-source Layer-1 capabilities opens up the world of new possibilities due to its Pure Proof of Stake technology. Generally, smart contracts are slow to propagate and do not scale for real-world use-cases.

Algorand Smart Contracts (ASC1), with its Smart Contract, arrives to work upon these shortcomings, which have slowed the adoption rate for Blockchain. The language through which this kind of technology proceeds is known as transaction execution approvable language (TEAL). Algorand’s ASC1s come with trustless programs that execute on-chain, where users can be confident that the program was run without error and the results have not been tampered with. The ability to automatically enforce custom rules and logic has been provided in ASC1s to make the Algorand development cost-effective and error-free.

What is Cardano?

Cardano is an open-source Blockchain technology that allows stakeholders to combine resources to form the stake pool. Because the elected representatives can't assume knowledge of building blocks. Timelines are further arranged in small chunks known as Epochs and consist of fixed slots. The screw-in slots rotate continuously. Each period has gathered stakeholders. The stock leader for this period also determines slots for the future period. This can be done by throwing the coin. It also doesn't mean a person with a higher government can get better salaries for elections.

Cardano is one of the fastest-growing Blockchain platforms based upon the Proof-of-Stake (PoS) protocol built through peer-reviewed research. Charles Hoskinson, co-founder of Ethereum, started the development of Cardano in 2015, but later, Cardano stood as an alternative to Ethereum. Cardano claims to offer scalability, interoperability, and sustainability on their network.

Many consider Cardano technology as an updated version of Ethereum, a second-generation Blockchain platform, while Cardano claims to be a third-generation platform. Cardano is the first Blockchain platform to use the high-level software development language ‘Haskell’ as its programming language. This programming language is more precise, formally verifiable, and better suited to applications that require high assurance.

Algorand vs. Cardano Detailed Comparison

License

Algorand is an open-source Blockchain protocol, and its repository is publicly available for anyone to audit, use, and build. While Cardano is an open-source Blockchain protocol under the custodianship of the Cardano Blockchain, the Cardano Foundation is a Swiss not-for-profit organization.

Consensus Mechanism

Algorand technology functions upon the Pure Proof of Stake consensus mechanism to support two types of nodes simultaneously optimizing for transaction throughput and decentralization - relay nodes and participation nodes. The difference between these two nodes is about configuration but not the software. Compared to other Proof-of-Work (PoW) protocols, in Algorand, participants need not solve cryptographic puzzles to propose or validate blocks.

In Algorand, the relay nodes function as network hubs and maintain connections to many other nodes. These relay nodes are used to efficiently communicate over the paths, ultimately reducing the number of hops and the transmit time of sending a message throughout the network. Other than these, performing deduplication, signature checks, and other validation steps and then re-propagating only the valid messages are some of these nodes' work. These relay nodes are often located at internet exchange points to decrease propagation time, and anyone can run a relay node.

In the Algorand consensus protocol, these Participation nodes are run to communicate with each other through relay nodes. These nodes propose and vote on blocks on behalf of the user’s stake within the consensus algorithm when authorized by the user’s participation key. In Algorand, everyone is encouraged to run a participation node, as they ensure the security of the Algorand Blockchain.

The Cardano uses the Ouroboros mechanism to achieve consensus, and under this mechanism, each node has the chance to be elected as a slot leader to validate a block. In this system, the chance of becoming a slot leader increases comparatively the amount of ADA staked to their pool up to the pool saturation point. Stake pools receive rewards in the event of successful validation, and further rewards are distributed to delegates of the stake pool; this provides an opportunity to earn ADA for taking part in consensus.

Speed, Security, and Scalability

Speed is pretty good in Algorand as an Algo can be sent in under 4.5 seconds, and that, like your payment, has almost instant confirmation once it has been made.

Algorand maintains strict security at the consensus protocol level and over the network level, as security is of utmost importance in the Public Blockchain network. Algorand’s security is designed in such a way that it prevents powerful adversaries from corrupting enough users to control block generation. In Algorand, during a network partition, the adversary can never convince two honest users to accept two different blocks for the same round, and in this way, it maintains security.

Scalability is maintained in Algorand as it uses Pure Proof-of-Stake (PPoS) to randomly select a small set of block proposers and verifiers. Under this mechanism, the users must receive a fixed number of messages to reach a consensus on the next block.

Cardano Blockchain with ADA cryptocurrency offers much cheaper and quicker transactions than other old-generation Blockchains. Using Cardano's Proof-of-Stake (PoS) algorithm makes it one of the most reliable platforms compared to other Blockchain development companies. In the PoS mechanism, the need for extra machines within the system is not felt, as the nodes will be responsible for throughput, and the system becomes less susceptible to interference.

Smart contract capabilities

In Algorand, Smart Contracts (ASC1) are segregated into two main categories, stateful and stateless. Here both types of Smart Contracts are written in an assembly-like language known as Transaction Execution Approval Language (TEAL), which can be interpreted by the Algorand Virtual Machine (AVM) running within an Algorand node. These TEAL programs can be written with the help of PyTEAL in Python language or even with a hand.

The functioning of Cardano is very much similar to Ethereum, where the Blockchain model is used together with Smart Contract and tokens. Cardano comes bundled with a two-tiered structure – Cardano Settlement Layer (CSL) and the Cardano Computational Layer (CCL). The CSL enables the transfer of the native cryptocurrency of Cardano (ADA) between other Blockchain participants. At the same time, the CCL consists of multiple components that enable tokenization and dApps.

Native token

The native token in Algorand is known as Algo, and all the key features of Algorand Blockchain are present in Algo. Token grants to the early backers and universities by Algorand Foundation for running relay nodes to help bootstrap a scalable and reliable initial infrastructure backbone. Algo launched over 4 million NFTs in the world of cryptocurrencies, roughly translating into 95,000 SIAE members’ rights.

Whereas ‘Ada’ is the native currency of Cardano, named after Ada Lovelace, a 19th-century countess, and English mathematician to be recognized as the first computer programmer.

Community support and Funding

Algorand has its community members and helps support groups across social media, groups, and forums where discussion over Algorand projects happens. The community is rapidly growing as they have announced a grant of $20000 for successful startups from the Algorand Foundation.

In terms of funding for Cardano, the initial funding was done through an Initial Coin Offering (ICO) and, as of now, raised $540000. Cardano has a community support forum that allows connecting with Cardano Blockchain development from around the world and engaging in an open discussion about the Cardano Blockchain development and its adaptability project. Also, there are community pages on various social media like Facebook, Twitter, Reddit, GitHub, and groups over Telegram.

Conclusion

Cardano strives to provide identities to those who lack access to financial infrastructure and empower them. Cardano is built over the positive elements found in the first two generations of Blockchain, and it aims to solve issues regarding scalability, interoperability, and sustainability, but due to lack of other features, it may lose out its sheen in the future, as we can say that the Cardano’s focus till now is limited towards the financial sector.

Although Algorand has a bright future with ongoing developments over the Algo ecosystem, several researchers think Algo is a promising architecture. But only the end can tell if Algorand will laugh in the Blockchain space. Algorand and Cardano have significant differences, and the targets of both platforms are different. Blockchain being such a useful technology, even we are much excited to see who will win over whom and how the potential of this novel technology is harnessed.
