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!).
Current permissionless blockchains are slow, insecure and fail to properly manage the real-world identity of their users. However, our blockchain solves all these problems by pushing the state-of-the-art on cryptographic research. Our identity solution integrates the most diffused identity network…
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…
How much is secrecy worth and how many times can a secret be sold? These fundamental questions are solved on the following paper: Thanks to the new financial models described on the paper, you can now quantify the value unleashed…
We have started open-sourcing some of our technology: An Optimal ICO Mechanism: a Python script to compute a Multi-Unit Vickrey-Dutch auction. The full implementation of the Optimal ICO Mechanism will be open-sourced soon. An example smart contract for the Optimal…
At Calctopia, we develop the future of computation and humbly offer it for your advantage: The Secure Spreadsheet: the first and only end-user program for encrypted computation. Secure computation has never been easier. Private and Verifiable Smart Contracts: cryptographically secure…
