Hi, I’m Jean Regisser, an Engineering Lead at cLabs and one of the makers of Valora. Bringing the power of Valora and the Celo Platform directly to anyone with a mobile phone, without intermediaries, is a mission we’re constantly motivated by. Making this vision a reality required some technical innovations I’m very excited to share with you all. Intuitive Valora lets you send money anywhere in the world using just a phone number. To make this possible, we built the Celo Lightweight Identity Protocol. It makes sending a payment to any phone number as easy as sending an SMS (and sometimes even cheaper!). It even allows you to send payments to your friends before they’ve downloaded Valora! When you create your account in Valora, you’ll confirm your Phone Number using a decentralized phone number confirmation process, during which 3 randomly selected validators (part of the Proof-of-Stake Celo blockchain) independently confirm your phone number (expect to receive three text messages). Once you’re confirmed, your phone number is kept private on-chain using a distributed cryptographic privacy scheme. If anyone sent money to your number before this point, the funds will be automatically transferred to your account after you confirm your number. Secure & Stable Valora lets you transact with Celo Dollars easily, allowing you to pay transaction fees in the same currency you are sending – a large improvement over the status quo for other crypto currencies. Mobile First With Valora, the benefits of decentralization are available to anyone. Valora runs the Celo ultralight client, a lightweight client syncing state with the Celo P2P Network, on-device to enable an experience where no centralized party is required to view your balance or submit a transaction. While we worked hard to make this extremely efficient. Additionally, Valora’s design is informed by the realities of wireless data access and smartphone capabilities worldwide -- if you’re in a low-connectivity environment (e.g. 2G) or using Valora on a highly resource-constrained device, just switch on Data Saver mode, which uses a trusted node to communicate with the Celo Network on your behalf -- the same level of trust as with any other experience, blockchain or otherwise. We’ll be active here and would love to answer any questions on how we built Valora. We hope you’ll check it out and let us know what you think! P.S. we're also hiring!
