Cardano Maps Out Final Build Phase as ADA Tests a Make-or-Break Support Level

Charles Hoskinson has sketched a future in which Cardano no longer needs to explain what it is still missing. In posts on X, the founder described the planned Leios upgrade as the last major piece of development before the network, in his personal view, carries every core function he set out to deliver from the start. The remark falls short of a formal release declaration, but it frames the coming architecture change as the capstone of years of incremental work.

At the heart of Leios is throughput. Cardano's mainnet currently manages an estimated 5 to 10 transactions per second. The upgrade is designed to lift that figure to roughly 100 transactions per second, with longer-term targets exceeding 1,000. Activation of Linear Leios is pencilled in for the first phase of the so-called Dijkstra hard fork, scheduled for late 2026 — though the rollout hinges on governance approval, the readiness of stake pool operators and the outcome of further test rounds.

Test Beds Already Outrunning the Old Consensus

Development data from Input Output suggests the groundwork is further along than the mainnet numbers imply. In the Musashi Dojo testnet, phase 1 reached a data throughput of 26.8 kilobytes per second, which developers say is about six times the ceiling of the existing Ouroboros Praos consensus protocol. Separate measurements in isolated environments had already hit peaks of nearly 1,000 transactions per second the previous month, while the Hydra scaling solution posted sharp speed gains for simple transfers in local test setups.

The live chain has had its own bursts of activity. Over the five days to 11 October, the network processed 1,780,896 transactions — 13.65% above the previous record set in November 2021. Ecosystem transaction campaigns helped drive the surge, pushing network fees to 337,720 ADA during that window.

A Second Language, and a Bridge to Bitcoin

Hoskinson is also personally designing a new programming language for Cardano, a move aimed squarely at the long-running debate over how easy the network is to build on. Cardano has leaned mainly on Plutus and Aiken; a purpose-built language could simplify smart contract development, though it raises questions about fragmenting developer resources. The concept links user intentions — so-called intents — with proof-carrying data and Groth16 zero-knowledge cryptography, embedding them in Cardano's transaction environment to improve efficiency and confidentiality for complex commands. No name, technical specification, testing regime or launch date has been disclosed.

The ecosystem is meanwhile advancing Midnight, a privacy-focused partner chain whose own language is called Compact. Whether the newly announced language will interact directly with Midnight remains unconfirmed. Hoskinson has held out Midnight security features intended to serve confidential transactions for autonomous software and AI agents.

Liquidity is the other front. To counter the "ghost chain" charge of insufficient real-world use, Cardano is pursuing a link to the Bitcoin blockchain, with Hoskinson confirming talks with Blockstream chief Adam Back on aligning the two ledgers' accounting models. Cardano runs an extended UTXO model; Bitcoin uses the classic version. Joining the architectures would let Bitcoin assets be deployed in Cardano's decentralized finance applications without altering Bitcoin's core software. Success will depend on user uptake and the broader regulatory climate.

The Chart Is the Immediate Problem

All of this lands in a soft market. ADA changed hands at 0.2154 USD on Monday, down 1.8% on the day, and has shed 34% since the start of the year. Recent sessions have given back earlier recovery attempts, leaving the token barely 1.6% above its 200-day moving average of 0.2121 USD — a long-term support line now under close scrutiny.

Analyst Giannis Andreou sees a weekly close above 0.278 USD as the first reliable buy signal, a break that could open the way toward 0.416 USD. A slide through the 0.14 to 0.16 USD support band would invalidate that recovery scenario.
