This includes a light-client syncing mechanism called Plumo, which allows Celo mobile and resource-constrained users to sync to the Celo blockchain faster, using only a few kilobytes of data. The platform also maps encrypted phone numbers to wallet addresses, aiming to simplify transactions on the blockchain for users of all experience levels.
