The authentication systems are being updated: EPID is being replaced by DCAP because Intel is deprecating itPassport’s Chip Authentication and Key Attestation will be used on mobile devices whenever availableadditionally, zero-knowledge proofs could be generated from mobile devices
In our latest paper (codenamed “Pravuil”), we introduce our latest innovation in consensus protocols for blockchains: a robust, secure, and scalable consensus protocol for a permissionless blockchain suitable for deployment in an adversarial environment such as the Internet. By introducing…
Our mobile apps for Android and iOS have been updated with a new functionality that matches your digital photograph contained within your National Identity Card or Electronic Passport with a photograph taken with your smartphone: to prevent privacy issues, your…
The Financial Action Task Force (FATF) held its FATF Week and Plenary on 19-21 February, officially adopting a new Guidance on Digital ID. One of the common misconceptions in the interpretation of the new FATF Rule 16 (i.e., the Crypto…
In practice, using cryptocurrencies without identity means that the costs of identification are externalized to third-parties and, worse yet, repeated and incurred multiple times: KYC/AML to access online exchanges and/or for ICO participation (the cost of a check ranges from…
Most announces of previous blockchains can be classified in the following groups: better hash algorithm (e.g., Litecoin) not using Proof-of-Work (e.g., Peercoin) better scripting/smart contracts (e.g., Ethereum) anonymous (e.g., Zcash, Monero) highly scalable (e.g., Zilliqa) a combination of the previous…
The Holy Grail of Blockchains, or how to build the most scalable, decentralised and secure blockchain, solved in the next publication (bonus: also including identity!).
How are smart contracts being verified nowadays? Generally, smart contracts are stored on the blockchain and the executing party must inspect their source code before executing them. If there are N parties that want to execute the source code, all…
The five ascending levels of intellect: Smart, Intelligent, Brilliant, Genius, Simple. Albert Einstein UPDATE: Please see Obliv-Java repository. Beyond the genius of secure computation, there is the simplicity of its use. Previous approaches to secure computation have developed their own…
Smart contracts are becoming the leading use case of public permissionless blockchains: nowadays, Ethereum is the main blockchain by the number of transactions (more than 50% compared to the rest of competitors) and more than 50% of those transactions are…
