This issue allows users to access tokens before they are released according to their vesting schedule. The problem was addressed...

Post-Quantum Blockchain: Challenges and Opportunities

Blockchain is a Distributed Ledger Technology DLT that offers numerous benefits including decentralization, transparency, efficiency, and reduced costs. Hence, blockchain has been included in many fields. Blockchain relies on cryptographic protocols especially public-key cryptography and hash...

Quantum Blockchain Survey: Foundations, Trends, and Gaps

Quantum computing poses fundamental risks to classical blockchain systems by undermining widely used cryptographic primitives. In response, two major research directions have emerged: post-quantum blockchains, which integrate quantum-resistant algorithms, and quantum blockchains, which leverage...

Efficient Blockchain-Based Steganography Via Backcalculating Generative Adversarial Network

Blockchain-based steganography enables data hiding via encoding the covert data into a specific blockchain transaction field. However, previous works focus on the specific field-embedding methods while lacking a consideration on required field-generation embedding. In this paper, we propose a...

Combating Reentrancy Bugs on Sharded Blockchains

Reentrancy is a well-known source of smart contract bugs on Ethereum, leading e.g. to double-spending vulnerabilities in DeFi applications. But less is known about this problem in other blockchains, which can have significantly different execution models. Sharded blockchains in particular general...

CVE-2022-31021

Ursa is a cryptographic library for use with blockchains. A weakness in the Hyperledger AnonCreds specification that is not mitigated in the Ursa and AnonCreds implementations is that the Issuer does not publish a key correctness proof demonstrating that a generated private key is sufficient to...

Design/Logic Flaw

Ursa is a cryptographic library for use with blockchains. A weakness in the Hyperledger AnonCreds specification that is not mitigated in the Ursa and AnonCreds implementations is that the Issuer does not publish a key correctness proof demonstrating that a generated private key is sufficient to...

CVE-2024-22192 Ursa CL-Signatures Revocation allows verifiers to generate unique identifiers for holders

Ursa is a cryptographic library for use with blockchains. The revocation scheme that is part of the Ursa CL-Signatures implementations has a flaw that could impact the privacy guarantees defined by the AnonCreds verifiable credential model. Notably, a malicious verifier may be able to generate a...

CVE-2024-21670

The CVE-2024-21670 issue affects the Ursa CL-Signatures revocation scheme used in Hyperledger Ursa. The revocation schema contains a flaw that can let a malicious holder of a revoked credential generate a valid Non-Revocation Proof, causing a verifier to accept a credential as not revoked when it...

Replay attack for authorized orders

Lines of code Vulnerability details Impact Detailed description of the impact of this finding. Nonce is used by sellers and buyers to avoid replay attack for their orders. However, since sellHash and buyHash only contain the order info and the nonce, it is still possible to have a replay attack...

Thief pulls off colossal, $600m crypto-robbery …and gives the money back

The largest crypto-robbery in history is rapidly turning into the most bizarre as well. Lets start at the beginning… In an apparent scream for mercy, 21 hours ago the Poly Network Team reached out via Twitter to “hackers” that had managed to transfer roughly $600 million in digital tokens out of...

Kim Dotcom's Decentralized Internet — For You, Powered By You

Imagine the internet that would offer you to communicate privately with anyone else without censorship, safe from the prying eyes of surveillance authorities…. … Decentralized, Encrypted, Peer-to-Peer Supported and especially a non-IP Address based Internet. Yeah, a New Private Internet that woul...
