Title:
METHODS, SYSTEMS, AND DEVICES FOR CONCEALING ACCOUNT BALANCES IN LEDGERS
Document Type and Number:
WIPO Patent Application WO/2020/096996
Kind Code:
A3
Abstract:
Disclosed herein are methods, systems, and devices for concealing account balances of permissionless distributed ledgers using multi-chain and/or directed acyclic graph (DAG) based structures, while maintaining publicly verifiable transactions. According to one embodiment, a computer-based method for recording a transaction in a ledger having a transacted amount, a first account balance associated with a sender and a second account balance associated with a receiver is disclosed. The computer-based method includes encrypting the transacted amount using a first shared key, decreasing the first account balance by the transacted amount, encrypting the first account balance with a first private key, increasing the second account balance by the transacted amount, encrypting the second account balance with a second private key. Additionally the ledger is configured for tracking the first account balance and the second account balance in at least one of a multi-chain structure or a directed acyclic graph (DAG) based structure, concealing the first account balance and the second account balance, and allowing public verification of the transaction over a network.
