Cardano's real-world utility is questioned as Ethereum's early design discussions resurface. Ethereum (ETH) is trading at ₹2,29,001 ($2,408.62), down 0.5% since this brief published. This is an original Token Times brief based on reporting by The Crypto Basic, with live market data added, as of Sun, 18 Oct 2026 07:00:02 UTC.
The debate highlights ongoing competition between blockchain models and their real-world applicability, impacting investor and developer confidence in Cardano's ecosystem.
- Cardano's 'ghost chain' claims are being challenged by supporters.
- UTXO model debate resurfaces after Adam Back's Ethereum revelation.
- Cardano's market cap is $8.42B, with ADA down 2.17% in 24 hours.
The debate over 
Cardano's real-world utility has intensified, with supporters pushing back against claims that the network is a 'ghost chain' with little practical use. This criticism comes amid a broader discussion about the unspent transaction output (UTXO) model, which Cardano employs.
The controversy was further fueled by comments from Blockstream CEO Adam Back, who claimed he had advised 
Ethereum's developers to adopt the UTXO model before they opted for the account-based model. This revelation has reignited discussions about the merits and drawbacks of different blockchain architectures.
Cardano's supporters argue that the network's design offers advantages in terms of scalability and security, despite the current criticisms. The debate underscores the ongoing competition between different blockchain technologies and their respective approaches to transaction processing and smart contract execution.
In the broader market context, the total crypto market cap stands at $2.8 trillion, with 
Bitcoin down 0.66% in the last 24 hours. Ethereum, which is often compared to Cardano, is also experiencing a slight downturn, with ETH trading at $2419.91 and down 0.69% in the same period. Cardano's ADA token is currently priced at $0.224226, reflecting a 2.17% drop in the last day.
The discussion around Cardano's utility and the UTXO model is likely to continue, with potential implications for investor sentiment and developer adoption. Observers will be watching for further developments and any concrete evidence of real-world use cases that could bolster Cardano's position in the market.

The chart plots ETH's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from Token Times's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 ETH ≈ ₹251,098.63 (about $2,408.62), down 0.9% over 24 hours. The rupee itself trades about 9.6% above the official rate on the P2P market, so a Indian buyer's effective cost differs from the headline dollar price.

Cardano's 'Ghost Chain' Claims Spark Debate Amid — questions & answers
What is the UTXO model?
The UTXO model is a method of transaction processing used by some blockchains, including Cardano, where each transaction consumes one or more unspent transaction outputs and creates new ones.
Why is Cardano being called a 'ghost chain'?
Critics argue that Cardano has limited real-world use, leading to the 'ghost chain' label. Supporters counter that the network's design offers unique advantages.
How has the market reacted to these claims?
ADA has dropped 2.17% in the last 24 hours, while the overall market remains relatively flat. Ethereum, often compared to Cardano, is also down slightly.
How much is 1 Ethereum worth in rupee today?
About ₹251,098.63 at the live peer-to-peer (P2P) USDT rate, which is what Indians typically trade at — equivalent to roughly $2,408.62. The rupee price moves with both ETH's US-dollar price and the USDT/INR rate; use our Ethereum in rupee page for any amount.
