An Impossibility Result for Strongly Group-Strategyproof Multi-Winner Approval-Based Voting This paper proves that no voting rule can be both strongly group-strategyproof and satisfy unanimity in multi-winner approval voting when selecting k out of m candidates (where k ≤ m−2). The result uses a reduction from the Gibbard-Satterthwaite theorem and shows limitations for resistance to coordinated manipulation. It impacts Cardano’s governance models, especially treasury or council elections using approval voting. This paper proves it’s impossible to make perfect group-safe voting with simple yes/no ballots.

Babel Fees via Limited Liabilities The paper introduces a model where users can delegate fee payment to others using ‘liability tokens’, enabling transactions without owning the native token (e.g., ADA). The system ensures incentives and security for relayers while preserving ledger correctness. This directly relates to Cardano’s Babel Fees concept, enabling broader user access and improved usability without sacrificing decentralization. This paper shows how someone can send a blockchain transaction without having the coin to pay the fee. They promise to pay later and someone else covers the cost. This idea is part of Cardano’s plan to make crypto easier to use.

Brick: Asynchronous Incentive-Compatible Payment Channels Brick is a novel payment channel that maintains security even under asynchronous networks, using a committee of ‘wardens’ to validate updates without time-based assumptions. It introduces a reward-and-penalty mechanism ensuring rational parties behave honestly, overcoming weaknesses in existing solutions that depend on synchrony or trusted third parties. Cardano could use Brick’s incentive-compatible model to design robust Layer-2 solutions. This paper makes a new kind of blockchain payment channel that works even if the network is slow or attacked. It uses a group of helpers and rewards to stop cheating. Cardano could use this for faster and safer payments.
Blockchains from Non-Idealized Hash Functions This paper investigates how to construct secure blockchain protocols using standard, non-ideal hash functions, addressing issues where existing proofs assume idealized models like the Random Oracle Model. It shows that under certain assumptions, security properties like consistency and chain growth can still be maintained using real-world hash functions.

This paper shows how to move coins across blockchains safely without using a big company. It uses a secret helper group and smart hardware. Cardano could use this to connect with other blockchains.
Chimeric Ledgers: Translating and Unifying UTXO-based and Account-based Cryptocurrencies This paper proposes a formal framework that unifies UTXO-based and account-based models via ‘chimeric ledgers.’ Cardano, which uses the EUTXO model, could leverage this framework to support hybrid transaction types, enhancing smart contract design and cross-chain interoperability. It shows how two types of money systems in blockchains can be combined into one. This lets people and developers choose the best parts of each system. Cardano might use this to improve its own system.
Coalition-Safe Equilibria with Virtual Payoffs This paper introduces the concept of Equilibrium with Virtual Payoffs (EVP) to model incentives in blockchain protocols. It demonstrates that Bitcoin may centralize under rational behavior, while Fruitchain achieves stronger equilibrium properties. The framework could guide Cardano’s incentive mechanism design to maintain decentralization and economic security. The paper explains how people in blockchains act when trying to earn rewards. It shows some systems may lead to one group having too much power. Cardano can use these ideas to stay fair and decentralized.
But Why Does it Work? A Rational Protocol Design Treatment of Bitcoin This work models Bitcoin’s incentive mechanisms using rational protocol design and verifies its equilibrium behavior under specific assumptions. It supports understanding how rational agents act in blockchain systems. Cardano can adapt these design principles to verify and improve the rational soundness of its own consensus and reward models. The paper checks if people following Bitcoin rules are acting in their best interest. It uses math and logic to confirm this is true in many cases. Cardano could learn from this to check if its own rules make sense.
Bypassing Non-Outsourceable Proof-of-Work Schemes Using Collateralized Smart Contracts The study shows how non-outsourceable mining (designed to prevent mining pools) can be bypassed using collateral-based smart contracts. It questions the effectiveness of such anti-pooling measures. Cardano’s smart contract and staking systems should consider such bypass risks when designing for decentralization and Sybil resistance. Some blockchains try to stop big mining groups, but this paper shows how to work around those rules. Cardano should be careful when making systems to stop bad actors from taking over.
Cardano Disaster Recovery Plan This document outlines the technical, governance, and operational recovery strategies for Cardano in case of disaster. It emphasizes multi-party governance, cryptographic safeguards, and key recovery procedures. It’s directly relevant to Cardano’s resilience planning and decentralization goals.

Consensus Redux: Distributed Ledgers in the Face of Adversarial Supremacy This paper introduces the concept of ‘self-healing’ for distributed ledgers, analyzing how PoW and PoS protocols recover after temporary periods of adversarial majority. It shows that Nakamoto-style PoW and Ouroboros Genesis PoS can recover security properties like consistency and liveness after a time proportional to the length and strength of the attack. Cardano, which uses Ouroboros Genesis, is shown to possess provable self-healing capacity, improving its resilience guarantees. The paper asks: can blockchains recover if bad guys take over for a short time? It proves that both Bitcoin and Cardano can return to normal afterward. Cardano is especially built to bounce back safely.
Conclave: A Collective Stake Pool Protocol Conclave proposes a novel protocol to allow multiple Cardano stake pools to act together as a collective, ensuring fair block production and profit sharing. The system leverages cryptographic primitives and threshold signatures to maintain decentralization while pooling resources. This can enhance Cardano’s scalability and reward fairness across smaller pools. This idea lets small Cardano pools team up fairly. They work together to earn rewards and keep things secure. It helps make the system more fair for everyone.
Composition with Knowledge Assumptions The paper examines how certain cryptographic systems can be securely composed when ‘knowledge assumptions’ are used (i.e., assuming adversaries know something if they act a certain way). It finds that such assumptions can be dangerous unless carefully constrained. For Cardano, which uses advanced proofs like SNARKs and recursive proofs, this caution helps avoid false security in composed protocols. It checks if complex crypto systems stay safe when combined. The answer is ‘not always’—unless certain things are assumed. Cardano developers need to be careful when combining advanced proofs.
Competitive Policies for Online Collateral Maintenance This research explores how systems can ensure that online collateral (e.g., for loans or stablecoins) is maintained fairly and competitively. Using game theory, it proposes mechanisms that discourage manipulation and encourage timely maintenance. This can guide Cardano-based DeFi systems in ensuring stable and trustworthy collateralized assets. This paper helps online money systems keep their promises. It stops cheating by setting smart rules. Cardano can use this to build safer lending tools.

It reduces the storage size from logarithmic to polylogarithmic, improving performance. Cardano can adopt this for lightweight clients or cross-chain proofs to enhance usability without sacrificing trust. It finds a way to save space when proving blockchains are real. Less data is needed, but trust stays strong. Cardano might use it to let people check the chain with small apps.
Cryptocurrency Egalitarianism: A Quantitative Approach This paper introduces a quantitative framework to measure how fairly cryptocurrencies distribute their mining or staking rewards. It finds that Proof-of-Stake systems, including Cardano, are generally more egalitarian than Proof-of-Work systems like Bitcoin. These results support Cardano’s use of PoS to promote more equal wealth distribution and lower barriers to participation. This study checks how fairly crypto rewards are shared. Cardano’s system shares more equally than Bitcoin’s. It’s better at letting more people join and earn.
Decentralised Update Selection with Semi-Strategic Experts This paper presents a governance model where semi-strategic experts vote to select software updates while being partially influenced by incentives. It uses game theory to model how such experts behave, and proposes safeguards to preserve decision quality and resistance to manipulation. Cardano’s on-chain governance mechanisms can adopt similar models to balance expert advice and decentralized decision-making. The paper shows how experts can help pick updates without being tricked. It builds a system where experts vote fairly, even if they want rewards. Cardano’s update system could use this idea.

It uses game theory and simulation to show that price discovery and fairness can be maintained across multiple currencies. This model may help Cardano or its sidechains distribute new assets in a trustless and efficient way【195†Decentralized Proof-of-Burn auction for secure cryptocurrency upgrade†L1-L3】. People can burn old coins to get new ones in a fair auction. It doesn’t need a trusted third party to set the price. Cardano could use this to launch new tokens safely.
Decreasing Security Threshold Against Double Spend Attack in Networks with Slow Synchronization The paper proves that when network delays exist, attackers need less than 50% of hash power to perform a successful double spend attack. It offers precise mathematical models and thresholds showing how network speed and block time affect vulnerability. These findings suggest Cardano must consider network sync delays in its consensus and block production settings【196†Decreasing Security Threshold Against Double Spend Attack in Networks with Slow Synchronization†L1-L3】. If the network is slow, attackers might cheat with less than half the power. The paper shows when this can happen and how to stop it. Cardano should watch for these network delays.
Differential Liquidity Provision in Uniswap v3 and Implications for Contract Design This paper analyzes how liquidity providers behave under Uniswap v3’s concentrated liquidity design, highlighting asymmetric returns and risks based on strategy.

FairTraDEX: A Decentralised Exchange Preventing Value Extraction FairTraDEX is a decentralized exchange protocol that eliminates extractable value (EEV) through a combination of zero-knowledge proofs, commit-reveal schemes, and width-sensitive frequent batch auctions. It formally guarantees that rational traders reach equilibrium at market prices plus fixed, non-extractable costs, addressing a core vulnerability in automated market maker (AMM) models. This approach is directly applicable to Cardano’s DEX ecosystem, offering a scalable, fair, and privacy-respecting solution. This paper introduces a way to make crypto trading fairer by preventing others from taking advantage of your trades. It uses math techniques to hide trades until everyone is ready. It helps make blockchain-based exchanges more honest.
Fait Accompli Committee Selection: Improving the Size-Security Tradeoff of Stake-Based Committees This paper proposes new committee selection mechanisms for proof-of-stake systems that improve the tradeoff between committee size and security. Using deterministic assignments and adaptive weighting, these methods significantly reduce the probability of adversarial overrepresentation. Cardano, which relies on stake-based committee systems like Ouroboros, can apply these techniques to optimize consensus and layer-2 committee formation, such as for sidechains or governance. The paper shows how to choose groups in blockchain voting to be smaller but still safe from cheating. It uses smart ways to pick members so bad actors can’t take over. This helps blockchains stay secure and fast.

Partial Allocations in Budget-Feasible Mechanism Design This work designs mechanisms to allocate partial services from agents (e.g., time or service levels), achieving truthful and budget-feasible outcomes with strong approximation guarantees. It advances procurement models that allow flexible contributions, important for decentralized governance and on-chain funding in systems like Cardano. This shows how to split tasks fairly when money is limited. It finds smart ways to hire people for part of their work. Cardano can use this idea for funding community jobs.
Pay To Win: Cheap, Crowdfundable, Cross-chain Algorithmic Incentive Manipulation Attacks on PoW Cryptocurrencies The paper demonstrates that attackers can use crowdfunding and algorithmic strategies to manipulate Proof-of-Work chains like Bitcoin at low cost. While Cardano uses Proof-of-Stake, the paper highlights the importance of designing economic incentives carefully. Cardano’s PoS design can avoid these risks but must still be wary of similar game-theoretic vulnerabilities. Attackers can cheaply trick systems like Bitcoin using smart crowdfunding. Cardano uses a different method, but it still needs to be careful. Good design helps protect from bad actors.
Payment Trees: Low Collateral Payments for Payment Channel Networks? The authors propose “payment trees” to reduce the amount of locked funds required in payment channel networks. This allows faster and cheaper off-chain transactions. Cardano’s Hydra or future layer-2 systems could benefit from this for scaling without large capital lock-ups. This paper shows a way to send money with less money locked up. It’s like using teamwork to move funds faster. Cardano might use this to make payments cheaper.
PEReDi: Privacy-Enhanced, Regulated and Distributed Central Bank Digital Currencies PEReDi is a framework for CBDCs that balances privacy and regulation using multi-party computation and selective disclosures. It maintains compliance while supporting anonymous use where permitted. Cardano could adopt similar methods in building privacy-respecting stablecoin or CBDC frameworks. It’s about making government digital money private but still following rules. People can stay anonymous in some cases. Cardano could use this for regulated, private payments.
Permissionless Clock Synchronization with Public Setup This paper builds on Ouroboros Chronos and proposes clock synchronization methods that don’t require trusted setup or central servers.

This study shows how blockchains can agree on time without trusting anyone. It uses randomness and stake. Cardano could use this to stay accurate and fair.
Policy-Compliant Signatures PCS schemes allow only signers whose attributes match the recipient and policy to produce valid signatures. They ensure strong privacy while enforcing transaction rules. Cardano can apply PCS to control smart contract access or regulated token transfers. PCS helps control who can sign messages based on rules. It keeps info private while stopping bad uses. Cardano could use this for rule-based transactions.
Post-Quantum Security of the Bitcoin Backbone and Quantum Multi-Solution Bernoulli Search The paper assesses the impact of quantum adversaries on Bitcoin’s backbone protocol and introduces Quantum MSBS as a more accurate model. It shows that while Nakamoto consensus can remain secure with adjusted parameters, future systems must account for quantum search capabilities. Cardano can use this analysis to guide future quantum-resilient upgrades to its PoS consensus. This study looks at what happens to blockchains when quantum computers become real. It shows how to keep them safe with new math. Cardano might use this to prepare for the future.
Practical Settlement Bounds for Longest-Chain Consensus The authors provide a refined analysis of how quickly transactions become irreversible in proof-of-work and proof-of-stake systems. These bounds help system designers estimate how many confirmations are needed for security. Cardano, using a PoS model, benefits from these theoretical guarantees for transaction finality. It tells how long we need to wait for a blockchain transaction to be truly safe. Cardano can use this to decide how many blocks to wait. Faster and safer confirmations!
Practical Settlement Bounds for Proof-of-Work Blockchains This work focuses specifically on PoW systems like Bitcoin, deriving exact settlement bounds under realistic assumptions. While Cardano is PoS-based, the math and methodology still inform similar analyses for its own consensus. It helps Cardano strengthen its understanding of finality under adversarial conditions. The paper explains how long to wait after a Bitcoin-like transaction before it’s unchangeable. Even though Cardano is different, this helps it learn about safety too.
Privacy Preserving Opinion Aggregation This paper designs a protocol to collect and compute statistics (like survey results) without learning individual answers, using homomorphic encryption and zero-knowledge proofs. It enables private yet trustworthy data collection. Cardano could adopt this for Catalyst governance voting or private community polls. It’s about collecting group answers without seeing who said what. Privacy stays safe while results are still real. Cardano could use this for voting!
Privacy-Preserving Blueprints The authors present a framework where anonymous credentials can be verified for sensitive conditions (like being on a watchlist) without revealing private information unless necessary. They implement this using ElGamal encryption and blueprint-style zero-knowledge protocols. Cardano could use this for privacy-compliant identity verification or selective disclosure in regulation. You can prove you’re not on a list without showing who you are—unless needed. It keeps your info safe while helping catch bad guys. Cardano can use this for trusted, private ID checks.
Privacy-Preserving Decision-Making over Blockchain This paper proposes a protocol that allows decisions (like voting or selection) to be made on a blockchain without revealing participants’ individual inputs. It combines privacy with verifiability using cryptographic tools like homomorphic encryption and zero-knowledge proofs. Cardano could adopt this for governance systems such as Catalyst voting to preserve voter anonymity while ensuring result integrity. It shows how groups can make decisions secretly and still prove it’s fair. Nobody knows your vote, but they can still count it right. Great for Cardano voting.
Probability Models of Distributed Proof Generation for zk-SNARK-Based Blockchains The authors propose a probabilistic model to analyze when and how zk-SNARK-based blockchain systems generate valid proofs in a decentralized way. It provides guidance on setting system parameters to balance proof reliability and latency. Cardano could use this to tune ZK-based extensions like Hydra or Midnight. This paper explains how to manage when and how proof-making happens. It helps balance speed and reliability. Cardano can use this for future ZK tech.
Probability of Double Spend Attack for Network with Non-Zero Synchronization Time This work mathematically models the double spend risk for PoW blockchains with real-world message delays. It shows that longer block delivery times and higher block frequency increase attack success rates—even when the attacker has less than 50% power. Cardano can use this model to better simulate risk scenarios and reinforce its PoS consensus security. If network delay is long, attackers can cheat more easily. Even small attackers might win. Cardano can use this math to stay safe.
Probability of Double Spend Attack for Network with Non-Zero Time Delay Similar to the above, this paper extends the modeling to continuous-time PoW blockchains, reaffirming that propagation delays significantly lower the security threshold for successful double spend attacks. It quantifies the confirmation blocks needed for various attack risks. Cardano can apply these formulas to evaluate robustness under delayed network conditions. This study shows exactly how delays make attacks more likely. It also tells how many blocks you need to wait to be safe. Useful for Cardano design.
Probability of Double Spend Attack for PoS Consensus with Ouroboros Praos Slot Leader Election Procedure The authors analyze the probability of double spend attacks in PoS blockchains using Ouroboros Praos, including both zero-delay and delayed communication models. They provide exact and upper-bound formulas for estimating attack risk. Cardano, which uses Praos, can directly apply these insights to fine-tune slot parameters and confirmation rules. This explains how safe Cardano is from certain attacks. It uses real Cardano math and settings. The result helps set how many confirmations we should wait.
Program Logics for Ledgers The paper proposes a formal logic framework to reason about smart contracts and distributed ledger behavior. It enables machine-checked proofs of contract correctness, which is critical for high-assurance applications.

It helps find problems before running them. Cardano can use this to make safer contracts.
Proof-of-Burn This paper analyzes the cryptographic underpinnings of “proof-of-burn,” a concept where users destroy coins to prove resource commitment. It formalizes the idea and explores secure applications like fair token launches or bootstrapping sidechains. Cardano could implement proof-of-burn for trustless token distribution or reputation mechanisms. Burning coins proves you’re serious. It helps start new projects fairly. Cardano might use it to give tokens or build trust.
Proof-of-Stake Blockchain Protocols with Near-Optimal Throughput This paper proposes a formal model and a PoS protocol that achieves near-optimal transaction throughput while maintaining security. By running multiple chains in parallel and re-including honest blocks, the protocol maximizes bandwidth without sacrificing robustness. Cardano can use these insights to design future scalable versions of Ouroboros. It shows how to make Cardano process more transactions without losing safety. The trick is to use multiple chains at once. This keeps the network fast and fair.
Proof-of-Stake Sidechains This paper introduces a construction for sidechains in PoS systems, enabling two-way token transfers between blockchains without trusted parties. It relies on cryptographic proofs and honest majority assumptions for security. Cardano can use this to enable cross-chain applications while preserving decentralization. It explains how to send tokens between different blockchains safely. No need to trust a third party. Cardano can use this to connect to other chains.
Proof-of-Work Sidechains The paper presents a decentralized method for linking PoW blockchains through Non-Interactive Proofs of Proof-of-Work (NIPoPoWs). It supports one-way and two-way pegged asset transfers and generic event triggering across blockchains. Though Cardano is PoS, the cross-chain event and token peg model can inform interoperability designs. It shows how two blockchains can talk to each other and move tokens back and forth. It uses special short proofs. Cardano can use the idea for cross-chain apps.
Proof-of-Work-based Consensus in Expected-Constant Time This paper proposes a PoW consensus protocol that achieves expected-constant confirmation time without sacrificing security, leveraging techniques like biased leader election. Although Cardano uses PoS, insights from fast PoW finality can inform optimization of PoS fork-choice rules. Cardano might apply such models to reduce user-facing confirmation delays. It’s a faster way to decide which block wins in a PoW system. It helps make blockchains respond quicker. Cardano could use similar ideas for faster decisions.
Proofs about Network Communication: For Humans and Machines The paper formalizes network communication protocols in a way that can be verified by both humans and machines, using tools like Coq and interactive proof assistants.

Instead of solving puzzles, miners train AI models. It’s secure and fair. Cardano might use this to combine AI and blockchain.
Reasonable Agda is Correct Haskell: Writing Verified Haskell using agda2hs The authors present a tool (agda2hs) that converts formally verified Agda code into readable Haskell, enabling verified software to be used in mainstream Haskell projects. It has been applied to Cardano development at IOG for trusted system components. This supports high-assurance tooling for Cardano infrastructure and smart contracts. This tool helps turn proven-safe programs into Haskell code. Cardano uses it to make sure important parts are bug-free. It’s like double-checking code with math.
Reducing Latency of DAG-based Consensus in the Asynchronous Setting via the UTXO Model This paper proposes using the UTXO model, like in Cardano, to enhance performance in DAG-based consensus under asynchronous conditions. It shows that UTXO enables more parallelism and lower latency than account-based models. Cardano can integrate these techniques into DAG-style or layer-2 improvements. UTXO helps process transactions faster in messy network conditions. It’s like organizing tasks so they don’t bump into each other. Cardano already uses UTXO, so this could help it get even faster.
Reputation at Stake! A Trust Layer over Decentralized Ledger for MPC and Reputation-Fair Lottery The paper presents a trust layer combining reputation with blockchain-based multiparty computation (MPC), enhancing fairness in decentralized lotteries and collaborative protocols. It ensures both security and verifiability even with partial participation. Cardano could apply this for fair on-chain randomness or Sybil-resistant voting. It uses a reputation score to help people work together safely and fairly. Even when some drop out, it still works. Cardano might use it for trusted voting or raffles.
Reputation-Based Incentive Model for Decentralized Analysis of Development Proposals This model improves Project Catalyst by tying rewards for proposal assessors (PAs) and veteran PAs (vPAs) to a reputation score. Reputation builds over time based on assessment quality, reducing manipulation and rewarding experienced participants. This is already being implemented in Cardano’s Catalyst governance. Good reviewers get more trust and better rewards. Bad ones lose points. Cardano’s Catalyst uses this to make reviews fair and useful.
Revisiting Key Decomposition Techniques for FHE: Simpler, Faster and More Generic The paper proposes improvements to key decomposition methods used in Fully Homomorphic Encryption (FHE), enabling more efficient operations. These techniques support more flexible and scalable encrypted computations. Cardano could integrate such improvements in privacy-preserving smart contracts or ZK systems. It makes private math faster and easier to do on encrypted data. That helps blockchains do secret tasks better. Cardano might use this in privacy tools.
Reward Schemes and Committee Sizes in Proof-of-Stake Governance The authors analyze how to best design DRep rewards and committee sizes under budget constraints in PoS systems like Cardano. They find that small, well-compensated committees often outperform large ones and propose threshold-based reward models to ensure high-effort participation. Fewer hard-working voters can be better than many lazy ones. Paying only the best helps good choices win. Cardano can use this to improve how it picks and pays DReps.
Reward Sharing Schemes for Stake Pools The paper introduces a reward sharing scheme with a Sybil-resistance trade-off using a saturation parameter that incentivizes decentralization. This is the core mechanism used by Cardano for stake pool delegation, ensuring both fairness and security. It balances pool size and rewards to prevent monopolization. Cardano pays rewards to stake pools in a smart way to stop any one from getting too big. It uses math to keep things fair. This paper explains how it works.
Round-Robin Beyond Additive Agents: Existence and Fairness of Approximate Equilibria The authors analyze fairness in round-robin scheduling where agents’ utilities are not additive, showing how to design approximately fair outcomes. These techniques can inform governance or voting time-slot mechanisms. Cardano might apply this to rotate committee or resource access fairly across diverse stakeholders.

It introduces real-world identity anchoring (vLEI) to ensure trust without sacrificing efficiency. Cardano can adopt this to make Hydra state channels regulator-friendly while keeping user privacy intact. This adds safe auditing to fast off-chain payments. It lets regulators check things without seeing everything. Cardano can use it to stay private and legal at the same time.
SCRAPE: Scalable Randomness Attested by Public Entities SCRAPE provides a scalable, publicly verifiable randomness beacon using verifiable secret sharing, useful in decentralized lottery, committee election, and consensus. The randomness can be verified by anyone and doesn’t rely on a trusted dealer. Cardano could use SCRAPE to fairly select DReps or validators in future governance upgrades. This system makes random numbers everyone can trust. It’s good for picking people fairly without cheating. Cardano might use it to choose committee members.
Scripting Smart Contracts for Distributed Ledger Technology This paper analyzes smart contract scripting paradigms and proposes improvements in usability and security via formal logic and functional languages. It emphasizes balancing expressiveness with safety guarantees. Cardano aligns with this philosophy through Plutus, which uses Haskell-based functional scripting for secure contracts.

Cardano has implemented similar cold delegation features, making this directly relevant to enhancing staking security. It lets people earn rewards safely without keeping coins online. That makes staking safer. Cardano already uses this kind of system.
SecureCyclon: Dependable Peer Sampling SecureCyclon is a peer-sampling protocol resilient to Byzantine behaviors, ensuring secure neighbor selection even under adversarial conditions. It enhances network layer trust and decentralization. Cardano’s peer-to-peer network could benefit from integrating SecureCyclon to harden against Sybil and eclipse attacks. It helps pick friends randomly and safely in a network. Even if some nodes are bad, it still works. Cardano could use it to make its network safer.
Securing Proof-of-Work Ledgers via Checkpointing This paper introduces two checkpointing mechanisms—federated and decentralized—to secure PoW ledgers against 51% attacks, with guarantees for both liveness and persistence. It also presents the “block lead” attack and offers defenses via randomized checkpointing and timestamping. Cardano (though PoS) could adapt timestamp-based ideas for liveness in sidechains or cross-chain bridges. It protects blockchains like Bitcoin from big attackers using smart checkpoints. Even if bad guys have most power, good users stay safe. Cardano can learn from this for sidechain safety.
Security Analysis and Improvements for the IETF MLS Standard for Group Messaging The paper identifies vulnerabilities in the MLS group messaging protocol and proposes cryptographic improvements for forward secrecy and resistance to insider attacks. Although not specific to Cardano, secure group messaging can support confidential governance or DRep communications. It informs secure off-chain coordination in blockchain ecosystems. It checks a group chat system for hidden security problems and fixes them. Cardano might use this for secure team messaging.
Security Analysis of Slot Leaders Election Procedure for PoS-based Blockchains with On-Chain Randomness Generation The paper analyzes grinding attacks on PoS slot leader election that rely on manipulating on-chain randomness. It shows that adversaries need at least 40% stake to have a meaningful impact, with full dominance requiring 44% stake. This directly applies to Cardano’s Ouroboros and highlights the importance of robust randomness for fair leader election. If someone owns 44% of the stake, they might cheat the block creation order. Cardano uses a similar system, so this helps it stay safe.
Security Limitations of Classical-Client Delegated Quantum Computing This paper proves that if a classical client wants to verify a quantum computer’s work privately, some core security properties must be sacrificed. It suggests that full security in quantum delegation likely requires quantum capabilities on the client side. Cardano doesn’t currently use quantum computing, but future-proofing protocols may require awareness of such limits. You can’t check a quantum computer’s work secretly unless you have quantum tools too. Cardano doesn’t use this now, but might care later.
Self-Reproducing Coins as Universal Turing Machine This work demonstrates that Turing-complete smart contracts can be achieved through recursive transaction chaining without native loops, using Rule 110 in a UTXO-based system. It shows that computation can span multiple transactions across blocks. Cardano’s Plutus scripts can potentially adopt similar designs to support broader expressiveness while maintaining safety. Even without loops, smart contracts can do everything computers do if they use many steps. Cardano’s system might do this too.
Serial Monopoly on Blockchains with Quasi-patient Users This paper models how transaction pricing changes when users are willing to wait (quasi-patient) and introduces δ as a decay parameter. It reveals that monopolistic pricing with user impatience leads to either high or fluctuating fees. Cardano’s fee and epoch-based reward model is explicitly referenced as a motivating contrast, and insights could refine Cardano’s fee market for long-term sustainability. It shows how fees change if users are okay waiting. If they’re impatient, fees stay high. Cardano uses a different method, but can learn from this.
Smart Contract Derivatives This paper introduces a novel mechanism allowing ‘derivative’ smart contracts to interact with and observe other smart contracts on Ethereum without requiring cooperation. The mechanism uses NIPoPoWs to enable introspective SPV clients. This design can inform Cardano smart contract enhancements, especially for cross-contract communication and decentralized insurance/futures design. This paper shows how smart contracts can work together without being designed for it. It helps make things like insurance and futures possible. It works using proof that events really happened.

This can help Cardano refine its decentralization strategy and policy alignment, especially for Intersect and Voltaire governance. This paper shows there are many ways to check if a blockchain is really decentralized. It gives a checklist to see which parts are controlled by too few people. Cardano can use this to improve its fairness and safety.
Title Summary High School Level Summary
Single-token vs Two-token Blockchain Tokenomics The paper compares single-token and two-token economic designs, finding that two-token systems can better isolate volatile investment incentives from stable transactional needs. This informs Cardano’s exploration of stablecoins (like USDA) and governance tokens (like DRep keys or $NIGHT). The paper compares using one coin or two coins in a system. Two coins can make things work better—one for spending, one for investing. This idea can help Cardano make better money tools.

You can use it in blockchains to keep secrets safe. Cardano might use this for private apps.
Stake Shift in Major Cryptocurrencies: An Empirical Study This study measures how much the stake distribution changes over time in large PoW blockchains, with implications for PoS security. It shows that using outdated stake data in PoS protocols introduces measurable risk. Cardano can apply these findings to evaluate and minimize risks from stake distribution lag in Ouroboros-based systems. This paper checks how much crypto ownership moves day to day. If a system uses old data, it can make wrong choices. Cardano must be careful not to trust outdated info.
Stake-Bleeding Attacks on Proof-of-Stake Blockchains This paper introduces ‘stake-bleeding’ attacks where adversaries accumulate rewards over time by replaying past honest transactions, even with no key corruption. It shows that such attacks bypass key-evolving cryptography and require mitigation like context-sensitive transactions. Cardano’s PoS protocols must incorporate such protections if removing checkpointing. This shows how attackers can cheat slowly in PoS systems to gain power. Even without hacking keys, they can trick the system. Cardano needs ways to stop this kind of trick.

No one can see who is trading what, but it’s still provably fair. This could be useful for private DeFi on Cardano.
Consistency for Functional Encryption This paper explores different notions of consistency in functional encryption (FE), especially under adversarial conditions like dishonest key generators. It emphasizes that consistency (output correctness under multiple decryptions) and confidentiality (data privacy) are distinct and should be independently verified. For Cardano, these findings are important for secure smart contract or confidential computation features using FE. Functional encryption lets you control what someone can learn from encrypted data. This paper checks if results are reliable even when someone tries to cheat. Cardano could use this for better smart contracts.
Consistency of Proof-of-Stake Blockchains with Concurrent Honest Slot Leaders The paper proves that PoS blockchains like Cardano can achieve optimal consistency even when multiple honest leaders exist in the same slot, by using combinatorial models like Catalan slots and UVP (Unique Vertex Property).

It provides strict mathematical models and shows that security thresholds are significantly higher in delayed networks. Cardano benefits by learning how to optimize confirmation policies in its PoS protocol. If internet is slow, Bitcoin needs more blocks to be safe. The paper shows how to calculate this. Cardano can use these ideas to make its network safer.

It works even if some people cheat. Cardano can learn from this to grow faster.
Proof-of-Burn This paper defines Proof-of-Burn (PoB) as a cryptographic primitive where coins are destroyed irreversibly to prove commitment or bootstrap new systems. The authors propose a secure, flexible PoB construction that can be used across cryptocurrencies. For Cardano, PoB could enable decentralized token upgrades or asset bridging without oracles or KYC. Burning coins proves commitment. This can be used to get new tokens in a fair way. Cardano could use this to safely upgrade or link coins.
Tiered Mechanisms for Blockchain Transaction Fees This paper introduces a novel tiered pricing model for blockchain transaction fees that dynamically adjusts based on urgency. It aims to maintain low fees for non-urgent transactions while keeping revenue high by charging more for urgent ones. For Cardano, this can inform alternatives to EIP-1559 and offer equitable fee handling for diverse DApp use cases. Like express lanes on a highway, this model gives faster or cheaper options for blockchain users. Cardano could use this to make fees fairer for all types of apps.
Tight Consistency Bounds for Bitcoin The paper refines the security analysis of Bitcoin under Δ-synchronous network delays, revealing how adversaries may gain advantage when block propagation is delayed. It introduces tighter bounds and new analytical tools.
