The biggest Cardano news today is the Ouroboros Leios testnet reaching a landmark performance result just days ago, arriving at a moment when ADA’s price is hovering near a critical support zone and the network’s broader DeFi story is accelerating rapidly.
The Musashi Dojo testnet recorded 26.8 TxkB/s, with Charles Hoskinson declaring the upgrade his personal finish line for the network.
Cardano Leios remains on the public testnet, where its first phase peaked at 26.8 TxkB/s — a metric that measures transaction data per second rather than raw transactions per second.
For context,
its Earth phase reached that peak compared with 4.51 TxkB/s for mainnet using the existing Praos consensus, making the test result roughly six times the current mainnet ceiling.
The scale of what the test achieved deserves a closer look.
During its final stable days, Leios handled 54% of all traffic reaching the chain, processing 18 times the number of transactions seen on real mainnet traffic while carrying 3.3 times the data.
Testing generated over 127,000 blocks and 30,000 endorser blocks, along with nearly 8,000 certificates.
These are not simulation numbers —
Input Output ran the test across 12 geographically distributed nodes operated by independent stake pool operators.
The path to mainnet, however, remains contingent on several gates.
Input Output engineering teams have scheduled the activation of Linear Leios for late 2026 as part of the initial phase of the Dijkstra hard fork, though actual deployment remains contingent on on-chain governance votes, stakeholder participation, and the performance of upcoming test environments.
Under the development roadmap, the Leios update targets an initial capacity of roughly 100 transactions per second, with long-term testing benchmarks projecting speeds exceeding 1,000 transactions per second once the implementation matures.
While the Leios milestone grabs technical headlines, the Cardano DeFi narrative has been moving fast too.
Hoskinson teased a “special gesture” if RealFi’s USD stablecoin sUSDrf reaches $1 million in deposits, making the remark after Strike Finance disclosed that $70,000 had already flowed into its liquidity vault.
A Cardano ambassador reported that RealFi had issued more than $7.6 million in stablecoins and tokenized funds on the network.
At the time of the report, both outcomes on a prediction market around the $1 million TVL milestone had nearly equal odds of around 49% to 50%, with more than 3.4 million ADA in buy volume.
For ADA holders watching price action, the picture is more sobering.
The price of Cardano (ADA) sat at $0.21 on October 19, 2026, with a 24-hour trading volume of $121.30 million.
ADA has logged a 12% weekly decline and more than a 10% drop so far in October, while ADA futures Open Interest fell to $475.58 million from $549.14 million the prior week, signaling weaker retail participation.
A bearish technical structure leaves ADA vulnerable to nearly 15% downside toward support around $0.1894, with price still below both the 50-day and 200-day EMAs.
On the upside,
technical analyst Nehal outlined a conditional bullish scenario where a clean daily breakout above a long-term descending trendline could target $0.30 and then $0.36.
The high concentration of estimated liquidations just above the current price at $0.234–$0.235 adds near-term resistance
that bulls will need to clear before any momentum builds.
There is also a deadline that ADA cardholders should not miss.
The official Cardano Card multi-chain crypto payment card will be discontinued on October 31, 2026.
This decision follows a change in business direction by Wirex, the partner behind the Cardano Card program, which will shut down its existing custodial infrastructure and move to a non-custodial model.
What to watch next: the Cardano news today centers firmly on whether Leios can move through its remaining governance votes and enter the Dijkstra hard fork on schedule. A confirmed Q4 2026 mainnet activation date would be a significant catalyst. On the price side, the $0.21 support level is the line in the sand — a weekly close above $0.2587 would be the technical signal that the prolonged downtrend is breaking. The RealFi TVL race toward $1 million is a live community event worth following for anyone interested in where Cardano’s DeFi ecosystem is heading.
