This blog will cover what exactly Cardano (ADA) is and what the coin stands for. Its mining, staking, smart contracts, the benefits of investing in this coin and the reason why it is hailed as the biggest and baddest ‘Ethereum killer’ out there.

Key Takeaways

  • Cardano was launched in 2017 through an ICO and was developed by Ethereum co-founder Charles Hoskinson
  • It works on a PoS model and is supposed to be the ‘Ethereum killer’ predominantly because of its smart contracts implementation.
  • ADA coins can be mined by staking, and the process is used to validate transactions on the blockchain
  • Benefits of investing in ADA include high scalability, low transaction times, high transaction volumes, environmental friendliness and potential applications through smart contracts.
  • Cardano is on track to become one of the biggest cryptocurrencies in the market, estimated to grow by at least 10000% in the next five years by experts.

What Exactly is Cardano (ADA)?

Cardano is a third-generation blockchain platform that is decentralised, just like all other viable cryptocurrencies. Cardano’s coin, ADA, works on a Proof-of-Stake consensus algorithm, unlike Bitcoin and Ethereum (yet), which still use the Proof-of-Work model. Cardano had been initially designed as a network aimed to be a more efficient alternative to PoW networks. The main features of the network are scalability, interoperability, and sustainability. Cardano poses a better network than traditional choices like Ether because they are burdened and limited by the infrastructure burden of growing costs, energy use, and slow transaction times.

Some background

Charles Hoskinson, the co-founder of Ethereum, understood the implications of these challenges to blockchain networks. He began developing Cardano and its primary cryptocurrency, ADA, in 2015. The coin was launched in 2017.

The Cardano platform runs on the Ouroboros consensus protocol, the first platform to be proved secure and the first to be informed by academic research on the subject. Each development in the Cardano network from its conception has brought progress to the network’s ability to achieve the milestones associated with adopting blockchain technology and the revolution of cryptocurrencies from PoW to PoS.

In recent years, ADA has posed as the alternative or replacement for Ethereum. Both platforms are used for mainly the same applications – smart contracts. Cardano considers itself a notch above Ethereum and calls itself an ‘updated version’ of Ethereum as a third-generation platform over Ethereum’s second-generation credentials. One of the main applications of the Cardano network is to manage and provide identity management and traceability services. 

About Cardano

History of Cardano (ADA)

Cardano was funded through an ICO, an Initial Coin Offering, similar to Initial Public Offerings in the stock market. When the token was launched, it debuted with a market cap of $600 million. By the end of 2017, it had a market share of $10 billion. Today (10th November 2021), Cardano’s market cap is estimated to be $74 billion. It ranks #4 on the list of top cryptocurrencies by market capitalisation. 

In the beginning, Cardano attracted users and more investment by creating the narrative that the network overcame the apparent shortcomings in the then crypto market. These mainly included the slow and inflexible transactions of Bitcoin and the non-scalable nature of Ethereum. Popularly known as the ‘Ethereum killer’, Cardano soon became a viable alternative to ETH in the crypto markets.

Ada Lovelace inspired the coin’s name ADA. A 19th-century mathematician believed to be the first computer programmer. The ADA sub-unit is the Lovelace, where one ADA = 1,000,000 Lovelaces.

Cardano Mining

Cardano’s network works on the PoS model. Here, coin holders generate new blocks and verify the payouts through a process called staking. Unlike the PoW model that currencies like BTC and ETH work on, Cardano’s miners do not have to guess hashes to mine a block. Hence, anyone with a significant amount of ADA holdings can become a currency miner without investing in expensive mining equipment.

The PoS mining system is beneficial because it eliminates forced and brute coin hashing and ensures a smoother and more stabilised blockchain development process. By eliminating the hash guessing part of the equation, a lot of energy gets saved. Environmentally and economically, this makes sense. This is the reason why PoS networks are on the rise, and PoW ones are taking a backseat.

Scalability is also another issue that gets solved by using the PoS model instead of the PoW. Expensive mining equipment, massive electricity requirements and a low chance of scoring a reward deter new users from entering the networks as miners. With the Proof-of-Stake model, miners are incentivised to stake their coins on staking pools (which we’ll come to in the next section) and earn some passive income.

Cardano Staking

Cryptocurrencies that support the PoW model allow you to earn or mine more coins by solving hashes with a powerful computer loaded with GPUs and ASICs. However, if you’re looking to earn cryptocurrencies that use the PoS consensus algorithm, you can do so by staking.

In Cardano, you can use the process of staking to validate transactions on the blockchain network. In this process, the verification of the chain is done by a protocol called node selection. Each new block mined needs to be added to a node. The algorithm selects which node will be used next based on how many coins the node has staked or locked away. Nodes don’t usually have one miner with a large number of coins. They’re operated through staking pools where people aggregate their coins together.

As a user, if you want to stake your ADA and earn some passive income, you can lock your coins away on a node. The more coins that are locked away, the higher the node’s chances of producing blocks. When blocks are mined by this method, all pool contributors get a reward proportionate to their contribution to the pool.

You earn rewards on them in a way that you earn interest in a bank’s savings account. You can unstake your coins from the network at any time. When staking your coins, they never leave your wallet. Staking your coins while you’re holding them for the long term gives you a source of passive income while also making the blockchain faster and more efficient.

Cardano Smart Contracts

Ethereum is the most essential platform currently being used to make smart contracts. According to International Business Machines, “automate the execution of an agreement so that all participants can be immediately certain of the outcome, without any intermediary’s involvement or time loss. They can also automate a workflow, triggering the next action when conditions are met.”

Cardano’s Alonzo upgrade has considerably impacted the currency’s adoption rate by crypto investors and developers. The upgrade allows users to develop and execute smart contracts on the Cardano blockchain and build DApps on the network. Thus, just like Ethereum, Cardano can also become a vehicle for developing and contributing to DeFi. The currency aims to eliminate banks and other intermediaries, allowing users to lend or borrow funds and earn interest in a savings-like account. 

The development of smart contracts on Cardano is a bigger deal still because of the immense scalability it provides for the future. While Bitcoin and Ethereum have significantly better-established networks and nodes, Cardano consumes a fraction of the power that Ethereum does. Fees used to transact in Ethereum are also really high compared to Cardano, which boasts fewer gas commissions on decentralised and other exchanges.

Cardano Future

Cryptocurrencies are getting adopted in more significant spheres gradually. Cryptocurrencies have seen many highs, from being a monopoly of early investors to becoming a legal tender in El Salvador. Although there’s a new currency that’s apparently on track to become the ‘next big thing’ on the Internet every month, Cardano (ADA) is actually at the forefront of the crypto revolution.

Like Bitcoin, ADA only has a limited number of coins, although it is much higher than Bitcoin’s limit of 21 million BTC. ADA’s upper limit is drawn at 45 billion coins. At the time of writing, there are roughly 32 billion ADA in circulation. In theory, this will help to prevent inflation up to a maximum value amount.

Benefits of Investing in Cardano (ADA)

Cardano is getting a lot of attention in crypto communities despite big coins like Ethereum and Bitcoin because of the several key benefits that it brings to the table. Firstly, Cardano is massively energy efficient compared to its peers. According to a report, Cardano only uses about 6 GW hours of energy per year, while Bitcoin consumes a whopping 100 TW hours-plus of energy per year. In contrast, Bitcoin and Ethereum are infamous for their energy-consuming network models that harm the environment and make the technology less scalable over time.

Cardano is also able to process a vast number of transactions per second. Unlike any other coin or token, ADA has high scalability. Currently, it can process roughly 257 transactions per second. Theoretically, that number could eventually grow to 1 million transactions per second after an upgrade called Hydra gets launched on the network.

As for its applications, ADA can be used to store tamper-proof records for students on the blockchain, authenticate pharma orders, or provide consumers with the option to track their records and financial metrics over the blockchain. Although only time can tell whether it is the ‘Ethereum killer’, Cardano does seem to be getting more efficient and appealing every month.
