Cardano (ADA) vs Ethereum (ETH): Early Proof-of-Stake and Network Design

Cardano launched with a proof-of-stake (PoS) system. Ethereum originally used proof-of-work and switched to PoS years later.

Cardano and Ethereum are two widely used blockchain platforms. Both run smart contracts, decentralized apps and staking. However, Cardano has introduced some features earlier, while Ethereum has adopted similar strategies later. This pattern continues to go along with how the networks are being built and updated.

Early Proof-of-Stake and Network Design

Cardano launched with a proof-of-stake (PoS) system. Ethereum originally used proof-of-work and switched to PoS years later. This gave Cardano a head start in running an energy-efficient and secure network from the beginning.

The earlier use of PoS gave Cardano more time to refine its staking process. It does this through delegation to involve more and support decentralization. Ethereum now uses a PoS model as well, but the switch required multiple updates and coordination across its ecosystem.

As of press time, Ethereum (ETH) was priced at $1,641.28, with a market cap of around $198.1 billion. Cardano (ADA) traded at $0.6481, with a market cap of about $23.3 billion, according to Coingecko data.

Transaction Models and Scalability

Cardano uses the extended unspent transaction output (eUTXO) model. This system helps avoid conflicts when processing transactions and makes outcomes easier to predict. Developers can write code that behaves consistently, even when many users interact with the blockchain at the same time.

Ethereum uses an account-based model, where each account holds balances and executes transactions. This model can be flexible but may lead to more complex interactions. To improve scalability, Ethereum developers are now testing ideas based on the UTXO model used by Cardano.

Cardano supports native tokens. Users can create and transfer assets without needing to write custom code. This makes it easier and safer to launch new tokens on the platform.

On Ethereum, each token type—like ERC-20 or ERC-721—requires a smart contract. Writing and managing these contracts adds cost and risk. Ethereum is working on improvements to make this process more efficient, but the need for custom code remains in place for now.

Cardano’s Governance and Community vs Ethereum’s

Cardano (ADA) is building on-chain governance tools. These allow users to vote on decisions and manage a treasury that funds future updates. The network is moving toward community-led management as part of its current development phase.

Ethereum decisions are made through social consensus and off-chain discussions. While this method has supported growth, it doesn’t include formal tools for users to vote or manage protocol changes directly. Cardano is putting those tools into place now.

Cardano vs Ethereum: Network Focus and Performance

Ethereum (ETH) has a larger user base and more developers. It is a well known crypto space support that knows a wide range of applications. The network is in the process of upgrading in order to lower the fees and make it a better user experience. Rollups are layer-2 tools that run more transactions at lower (than Layer 1) cost.

Cardano is working on features that support long-term growth. Its Hydra scaling solution had good results in a late 2024 test where it processed up to 1 million transactions per second. This is progress in scaling the network without modifying its core.

Currently, Ethereum has about 120.6 million ETH in circulation with no fixed supply cap. Cardano has about 36 billion ADA in circulation, with a capped supply of 45 billion.

In fact, ETH is known much more than ADA but ADA provides very competitive entry costs and has relatively low risks compared to certain markets.
