Every Friday, we publish our weekly #Cardano development update. So for the lowdown on what IOG's dev team has been working on last week, head on over and take a look👇 essentialcardano.io/development-up…
🔬 CORE TECHNOLOGY: The networking team improved stability and performance, updated software, and prepared for releases. The consensus team progressed on Genesis design and improved BlockFetch logic while the DB Sync team optimized UTXO query speed and rewards performance.
💳 WALLETS & SERVICES: The team updated vulnerable libraries in #Daedalus and worked on improving the Lace desktop application. The Adrestia team worked on community feedback about Lace and are preparing for the first big cardano-js-sdk and @lace_io update.
💻 SMART CONTRACTS: The #Plutus tools team documented the Marconi sidechain architecture, and the core team continued working on the sums-of-products and Plutus Tx compiler optimization. The #Marlowe team focused on Merkleization formalization and the Isabelle spec.
🔎 BASHO (SCALING): The #Hydra team conducted an April review and published the monthly report. They also updated Hydra Head V1 spec, while the Mithril team completed the implementation of the new certifier service and the multi-signer in the aggregator.
👥🌐🗳️VOLTAIRE: Finally, discussions on #CIP1694 are about to go global, and the Member-Based Organization (MBO) published an update on their progress.

Cardano's EUTXO model brings determinism and predictability to blockchain! It builds on Bitcoin's UTXO but enhances it for smart contracts and complex apps without sacrificing security or simplicity.
So what does it mean?
1/7
@IOHK_Charles says EUTXO is ‘hand-in-glove built for isomorphism between the off-chain and on-chain.’
Essentially, equality between the two. This means what you see off-chain is what happens on-chain.
2/7
A Bitcoin wallet is like a jar holding coins (UTXOs). To spend $30, you'd use a $50 coin and get $20 change – a new UTXO. Cardano extends this by adding data and logic, creating more versatile UTXOs beyond simple value storage.
3/7
Cardano's sustainable future and competitiveness depends on research & innovation.
Today, Input | Output Research submitted its 'Cardano Vision - Work Program 2025' proposal to fund the foundational work required for long-term growth.
All aimed at scalability, sustainability & interoperability and defined through an evidence-based approach.
2/6
Execution will be led by the Input | Output Research team, the leading blockchain research network worldwide including more than 14 universities, who have published over 200 peer-reviewed papers involving more than 150 researchers.
This continues the foundational research that built Cardano.

📢 Yesterday, November 25, 2024, the IO Research team successfully tested Halo2 verification in Plutus on the Mainnet network. 💪🧵
IO Research ran the verification of a Halo2 ZK proof for the Ad-hoc Threshold Multi-Signatures scheme (ATMS) checking 50 out of 90 signatures. You can see the transactions here.
The first tx locks the funds, the second unlocks the funds upon verification of a Halo2 proof for ATMS signature 50 out of 90. The locking tx costs 0.16 ADA fee, the unlocking tx (Halo2 verification) 2.03 ADA fee which is reasonably low.
⭐ OUT NOW: Daedalus 6.0.1 for mainnet, preprod & preview.
The Daedalus 6.0.1 release upgrades to node 9.1.1 to fix the ledger replay issue in the Conway era. This update ensures that nodes no longer replay from genesis but instead replay as expected.
⚠️It is mandatory for all #Daedalus users to upgrade to this version. 1/🧵
⚠️Note that if you have already experienced this issue, your Daedalus will likely replay the ledger state from genesis (0%), so you may see longer synchronization times.
2/🧵
Existing users will get a prompt to update via the Daedalus newsfeed. If you are new to #Daedalus and would like to download this new release, download it ONLY from the official site: 3/ 🧵daedaluswallet.io/en/download/
⭐ OUT NOW: #Daedalus 6.0.0 for mainnet, preprod & preview.
Daedalus 6.0.0 is a mainnet release required to cross the upcoming Chang hard fork and operate in the Conway era.
⚠️It is mandatory for all #Daedalus users to upgrade to this version.
1/🧵
This version upgrades to node 9.1.0, #Cardano wallet v2024-07-27, the dependent Ledger and Trezor hardware wallet libraries, and fixes the #Daedalus auto-update feature to resolve the issue when running Daedalus on Linux with enabled AppArmor reported here:

⚠️Please note that since this release replays the ledger state from scratch (0%), users may experience longer synchronization times.
Today, we’re delighted to share with you the first two videos in a series which will highlight some of the work of IO’s research division and dive deeper into some of its key papers. 🧵
1/ In this video, Giorgos Panagiotakos, a research fellow at Input Output, delves into scaling throughput and specifically Ouroboros Leios, a new member of the Ouroboros protocol family that achieves near-optimal throughput.
Traditional #blockchain protocols use a leader-based approach for block proposals, but this often results in suboptimal throughput.
Panagiotakos highlights the importance of high throughput for reducing congestion and enabling the efficient operation of layer 2 applications.
Watch now:
2/ The Ouroboros Leios paper is also available for you to read here:
A future video will help outline how fundamental research informs IO’s work and feeds into its prototyping and development work, so stay tuned for that in the near future.iohk.io/en/research/li…
