Here’s how we’ll optimize & scale securely as we grow
1️⃣ Block size increase📈
The bigger the block, the more transactions it can carry. We recently increased block size by 12.5%; we’ll apply further increases over time based on ongoing system monitoring and network health.
2️⃣ Pipelining
Improves block propagation times by coalescing validation & propagation. The goal is for blocks to be propagated to at least 95% of peers within five seconds by reducing the ‘dead time’ between blocks.
3️⃣Input Endorsers
Input endorsers improve block propagation times and throughput by allowing transactions to be separated into pre-constructed blocks. This improves the consistency of block propagation times and allows higher transaction rates.💪
🖥️ More efficient memory usage across the chain. Specifically, memory improvements in Unspent Transaction Output (UTXO) handling, stake distribution, live stake distribution and pools, and hash representation.
5️⃣ Plutus script enhancements
Even more effective usage of the powerful eUTXO model through smart contract optimization, including reference inputs, #Plutus Datums & script sharing.
6️⃣ Node enhancements
Improvements will help even distribution of stake and reward computations across the epochs, thus providing greater headroom for block size increases.
7️⃣ On-disk storage 💿
By storing portions of the protocol state on disk, nodes will need to hold less in memory.So RAM-constrained systems will be able to run nodes provided they have sufficient storage, and memory will no longer be a bottleneck on scalability.
8️⃣ Sidechains ⛓️
EVM sidechains will add capacity; projects coming to Cardano include dcSpark’s Milkomeda and IOG’s Mamba.
9️⃣Hydra
Introduces isomorphic state channels to maximize throughput, minimize latency, incur low to no costs & reduce storage requirements. Hydra provides a more efficient means to process transactions off-chain while using the main-chain ledger as the secure settlement layer.
🔟Off-chain computing
Offloading some of the computation, for example with Asynchronous Contract Execution (ACE) can drive greater core network efficiency. Transactions occur outside the blockchain itself, yet can offer fast, cheap transactions via a trust model.
1️⃣1️⃣ Mithril
Mithril will improve chain synchronization while maintaining trust. The result? Multi-signature aggregation that is fast and efficient without compromising security features.
Scaling #Cardano is a process. Early in this process, we do anticipate periods of intense demand, with network congestion at peak times. We’re early on an exciting journey & usage will be high.
At times we’ll all feel we want to move quicker. But secure, incremental improvements & building for the long term remains paramount. Remember: slow & steady wins the race 🏁.
Security, decentralization and steady, careful scalability. It's all in the plan. Always has been.
Cardano’s next chapter will be shaped by all of us.
In an ongoing series of threads, IO shares its proposed roadmap with the community, focusing on scalability, usability, and interoperability. These aren’t standalone ideas, but together, they help drive us towards a vision for where we take Cardano next.
Grinding attacks, where network leaders manipulate block additions for re-election advantages, pose a threat, and existing Ouroboros anti-grinding measures can impact settlement times. 2/7🧵
The anti-grinding feature, proposed as part of node improvements, focuses on improving Ouroboros by making grinding attacks harder for adversaries, with minimal overhead for honest participants. 🛡️

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.

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.
