'Carry Protocol is a blockchain project that compensates consumers for sharing their data and receiving ads. Carry compensates individual consumers for 1. sharing their offline purchase data to build the most comprehensive offline purchase database, and 2. receiving ads from advertisers that use the Carry database to send targeted ads. Carry empowers consumers by giving them back the full control of their data and its monetization, and enables businesses to send targeted ads to the right consumers using the shared data. '
Zen is a decentralized financial platform, built from scratch with the goal of providing people with a secure, scalable and useful infrastructure for creating their own financial instruments, and trading them directly without intermediaries.The Zen blockchain is secured by multiple proof-of-work algorithms, with token-holder voting on the balance between them. Multi-hash mining creates robust incentives for miners to deliver efficient, reliable security.Zen smart contracts are written and secured by a subset of the F* functional programming language, allowing users to: A) Prove the amount of resources a contract will consume and provide the necessary fees for running the contract to miners, removing the need for a “gas” based system.B) Prove their contracts meet a given specification, meaning they can prove the contract will definitely do (or not do) something given a specific set of parameters.The Zen platform comes with a built-in solution for oracles, which provide contracts with useful real world data.Finally, Zen is integrated with the Bitcoin blockchain, allowing contracts to observe and respond to native bitcoin transactions
