Cardano Leios DRep Vote Approves 27.7M ADA Scaling Push
— By Whatsertrade in news
Cardano DReps approved the Leios proposal on May 25, 2026 with 84% support, unlocking 27.7 million ADA from the treasury. Leios is Input Output's research-grade throughput upgrade aiming to push monthly transactions from 800,000 to over 27 million by 2030. Testnet activates June 23, 2026. Five additional Input Output proposals also passed including 11.8M ADA for Plutus improvements. The Pogun BTC DeFi proposal failed at 32.4% support.
Cardano DReps approved the Leios proposal on May 25, 2026 with roughly 84% support, unlocking 27.7 million ADA from the treasury to fund the next phase of network scaling. Leios is Input Output's research-grade throughput upgrade designed to push Cardano from around 800,000 monthly transactions to over 27 million, the headline target of the network's 2030 vision. The vote also approved five additional Input Output proposals, including 11.8 million ADA for Plutus smart contract improvements, while the Pogun Bitcoin DeFi proposal failed at 32.4% support.
The Leios testnet is scheduled to go live on June 23, 2026, with the protocol progressing through Software Readiness Levels 5 to 8 before mainnet activation. The vote is procedurally separate from the Cardano V11 Van Rossem hard fork vote scheduled for May 29, which handles a different protocol upgrade track.
What Leios actually changes
Leios is a research-grade throughput overhaul for Cardano's Ouroboros consensus. Instead of trying to squeeze more transactions into the existing single-pipeline block structure, Leios introduces a parallel block production model that lets the network process multiple input blocks concurrently, then aggregate them into a final settled state. The design is meant to increase effective throughput by an order of magnitude while preserving Cardano's deterministic finality and stake-based security model.
The headline scaling number is 800,000 monthly transactions to over 27 million. That figure comes from the Cardano 2030 vision presented by Input Output and assumes Leios mainnet activation plus complementary improvements to Plutus smart contract execution and Mithril light-client infrastructure. The throughput jump matters because Cardano DEX daily volume has historically been an order of magnitude below comparable Layer 1s, in part because the chain's transaction capacity caps the size of liquid markets that can operate efficiently onchain.
The DRep vote in detail
DReps (Delegated Representatives) are Cardano's onchain governance actors under the CIP-1694 framework activated in 2025. Each ADA holder either votes directly or delegates their voting power to a DRep. The Leios proposal cleared the 84% DRep approval threshold on Sunday, May 25, 2026, unlocking 27.7 million ADA from the treasury earmarked for Input Output's continued Leios research and engineering work.
Five other Input Output proposals passed simultaneously in the same vote cycle. The most consequential of those is the Plutus improvements package, funded at 11.8 million ADA, which covers smart contract execution optimizations expected to lower script costs and improve developer ergonomics. The failed proposal, Pogun Bitcoin DeFi, fell short at 32.4% support; it had pitched a Bitcoin-collateralized DeFi suite native to Cardano, but DReps appear to have preferred the throughput-and-tooling track over a Bitcoin DeFi branch.
Implementation timeline
- May 25, 2026: DRep vote closes with 84% approval, 27.7M ADA unlocked
- June 23, 2026: Leios testnet activation
- 2026 to 2027: Software Readiness Level progression from SRL 5 to SRL 8
- Mainnet: Activation after SRL 8 maturation; specific date not yet set
- 2030 vision: Combined Leios plus Plutus plus tooling targets 27M+ monthly transactions
Cardano governance is finally working
The Leios vote is one of the cleanest demonstrations of CIP-1694 governance functioning at scale. DReps representing meaningful stake weighed in on a complex technical proposal, treasury funds were allocated with onchain transparency, and competing proposals (Pogun BTC DeFi) failed on merit rather than procedural collapse. This is a measurable contrast to Solana's Alpenglow upgrade rollout, which is foundation-led rather than treasury-vote-led, or SXT's token unlock, which had no DAO process at all.
For ADA holders, the practical implication is that treasury spending is now legitimised by onchain vote. The 27.7M ADA Leios allocation has DRep approval, which is harder to challenge politically than a foundation-only decision. This matters for institutional ADA holders who need a clear governance audit trail before deploying capital.
Impact on ADA and Cardano DeFi
The Leios approval is fundamentally bullish for Cardano's long-term DeFi narrative because throughput is the single biggest constraint on Cardano DEX growth. Daily Cardano DEX volume has stagnated around modest figures while comparable Layer 1s have processed multiples more. A successful Leios rollout lifts the ceiling on what's possible for Cardano-native DEXes, lending protocols and stablecoin issuance.
The implementation risk is non-trivial. Leios is research-grade and the SRL 5 to 8 progression is a multi-quarter process. Anyone modelling Cardano DeFi on the assumption of immediate throughput gains will be early. The realistic bull case is that mainnet activation lands in 2027, by which point the broader ecosystem (DEXes, RWA platforms, stablecoin issuers) has had time to plan for the higher capacity ceiling.
Things to know
Where to track Leios progress
The official sources are the Input Output research blog and the Cardano governance dashboards on cardanoscan.io, which show DRep vote outcomes and treasury balances onchain. DEXTools tracks ADA pools and Cardano-native DEX volume, which will be the first quantitative signal that Leios is delivering throughput gains once it activates.
Between now and June 23, watch for Input Output's testnet documentation drop and DRep commentary on how Plutus improvements interact with the Leios design. The combination of those two upgrade tracks is what determines the practical throughput ceiling, not Leios in isolation.
Frequently asked questions
What is Cardano Leios?
Leios is a research-grade throughput upgrade for Cardano's Ouroboros consensus that introduces parallel block production to push monthly transaction capacity from around 800,000 to over 27 million as part of the network's 2030 vision.
What did the DRep vote approve?
The DRep vote on May 25, 2026 approved the Leios proposal with 84% support, unlocking 27.7 million ADA from the treasury. Five additional Input Output proposals also passed, including Plutus improvements funded at 11.8 million ADA.
When will Leios go live?
The Leios testnet activates June 23, 2026. Mainnet activation depends on the protocol progressing through Software Readiness Levels 5 to 8, a multi-quarter process spanning 2026 to 2027.
Why did the Pogun proposal fail?
The Pogun Bitcoin DeFi proposal received only 32.4% DRep support, falling below the approval threshold. DReps appear to have preferred funding throughput and tooling work over a Bitcoin DeFi branch.
