# Phonebook Reputation MVP

### Overview <a href="#overview" id="overview"></a>

Phonebook lets you look up phone numbers and check their reputation through community votes. All data is stored in blockchain smart contracts. Each number gets a reputation score, calculated by flexible algorithms in smart contracts. To vote, connect your wallet and verify your number.&#x20;
