FAQ
What is Overdraft?
Overdraft is a novel offline payment system that enables users to conduct transactions without immediate blockchain interaction. It utilizes a reputation-weighted loan network, allowing potential payment receivers to assess the likelihood of being paid, thereby facilitating secure offline transactions.
How Does Overdraft Work?
Overdraft operates by maintaining a loan network weighted by online reputation. Users pledge to cover another user's payment if necessary, creating time-limited agreements. Offline users rely on their last known view of this network to decide on transaction participation. Once back online, transactions are committed to the blockchain, with any conflicts resolved deterministically.
What Makes Overdraft Unique?
Overdraft stands out by shifting reliance from trusted hardware to user-based reputation assessments. It incorporates incentives for users and is designed to be resilient against Sybil attacks, enhancing security in decentralized networks.
Who Are the Founders of Overdraft?
The Overdraft system was developed by Nektarios Evangelou, Rowdy Chotkan, Bulat Nasrulin, and Jérémie Decouchant, researchers focused on blockchain and decentralized systems.
