Cardano's Hoskinson Builds New Programming Language as DeFi Activity Lags

Hoskinson is building a new language for Cardano

Cardano founder Charles Hoskinson says he is developing a new programming language for the blockchain. He said he is working with Lucas Rosa, a software engineer at Input Output Global, on a language that supports intent-based transactions and proof-carrying data using Groth16 cryptographic proofs.

Groth16 is a type of zero-knowledge proof, a method that lets a computer confirm information is correct without revealing all of it. The announcement came after Hoskinson said the upcoming Leios upgrade would complete his original vision for Cardano.

At the same time, activity on Cardano remains small. CryptoSlate reported that the network's decentralized finance applications hold about $63 million in assets, even though the ADA token has a market value of roughly $8.3 billion.

Key numbers behind Cardano's DeFi gap

• Cardano's decentralized exchanges handled about $927,000 in transactions in the 24 hours before Oct. 19, according to DefiLlama.
• Weekly trading volume was $8.35 million, down 25% from the prior seven-day period.
• The network recorded 12,716 active addresses and 28,146 transactions that day, generating about $2,196 in blockchain fees.
• Cardano's stablecoin supply was about $70 million. Stablecoins are digital tokens pegged to a traditional currency, usually the US dollar.
• Solana held about $5.9 billion in DeFi deposits and processed $1.45 billion in decentralized exchange trades in the same 24-hour period, with stablecoin supply above $15.5 billion.
• Solana's market value is about $62 billion, roughly seven times Cardano's, but its DeFi deposits are more than 90 times larger.

Why limited liquidity is a problem

Decentralized finance, or DeFi, covers financial services that run on a blockchain without a traditional middleman. These services need enough money in the system to work well. Exchanges need liquidity — available funds — so large trades do not move prices sharply. Lending platforms need deposits and borrowers to earn revenue.

CryptoSlate reported that low activity can make it harder for developers to keep applications running, which in turn gives new capital less reason to enter the ecosystem.

What the new language would do

Intent-based systems let users state the result they want from a transaction, and software carries it out under set conditions. Supporters say this could simplify operations that involve swapping several assets, running actions automatically, or settling complex deals.

Proof-carrying data attaches cryptographic evidence to information to show it is valid. Combined with Groth16 zero-knowledge proofs, this could let applications check certain transactions or computations without exposing all the details.

Hoskinson described the proposed language as the first of its kind, according to CryptoSlate. However, its architecture, performance details, and technical specifications have not been published. Lucas Rosa's role is notable because he previously helped develop Aiken, a language designed to make building smart contracts on Cardano easier.

Leios aims to raise transaction capacity

Cardano is also working on Ouroboros Leios, an upgrade meant to increase how many transactions the blockchain can process. The development roadmap targets 10 to 65 times higher throughput through a phased rollout. Hoskinson described Leios as the last piece of his original vision, which he said also includes decentralized consensus and governance, the extended unspent transaction output accounting model, Plutus smart contracts, formal verification, and multiple independent node implementations.

What is confirmed

CryptoSlate reported that Hoskinson said he is working with Rosa on the new language, and that Hoskinson described Leios as completing his original vision. The DefiLlama figures for Cardano and Solana activity on and around Oct. 19 are reported data. The claim that the language is the first of its kind is Hoskinson's description, not an independently confirmed fact.

What is still unclear

No launch date has been given for the new programming language, and its design has not been published. Leios has also not yet been deployed. It is not known whether either effort will increase demand for Cardano's financial applications.

Why it matters

Cardano's market value is far larger than the amount of money actively used in its DeFi apps, and its trading activity is much smaller than Solana's. That gap suggests technical upgrades alone may not bring in users and capital. The value of the new language and the Leios upgrade will depend on whether developers build popular applications with them.

What happens next

Both projects are still in development. Leios is awaiting deployment, and the new language has no announced timeline.
