Real-time blockchain fraud detection

Real-time blockchain fraud detection

Use Quine to detect and trace fraudulent transactions across blockchains in real time.

The Problem

Real-time linking of transactions, accounts, wallets, and blocks within and across blockchains is not possible with current solutions. Instead, the user must either rely on batch processing, which means results are out of date, or perform recursive lookups across table joins, which means unacceptable latency.

The Solution

Graph data structures are ideal for modeling the relationships described in blockchain events. Flows of cryptocurrency between accounts and wallets are ideal inputs for graph data modeling. Accounts, addresses, time references, devices, assets, transaction details, etc. are all examples of categorical data connected by relationships and are therefore ideal to be represented as the nodes, edges, and properties provided in a graph data model. Most importantly, relationships between entities are first class citizens in the data model so the costs and complexity associated with table joins is entirely eliminated.

Quine easily ingests event feeds from multiple sources and creates a single unified view of activity on the blockchain(s). When fraudulent activity is reported, or when evidence of fraud emerges, Quine's standing queries instantly recognizes the patterns and triggers an alert. Now the client is not only detecting the fraudulent behavior in real time but blocking transactions before they can complete. Of course, many fraud alerts are delivered well after a transaction occurs and the Quine streaming graph can instantly provide a complete list of past transactions for a wallet or block to aid investigations or to block future transactions with related parties.

In the above screenshot from Quine's Exploration UI, you can see how Quine makes it easy to trace all the accounts with which an account engaged in fraudulent activities interacts.

Try An Example Yourself

It is simple to try Quine yourself using the Ethereum Recipe on

Models data on the thoroughgoing Ethereum blockchain using tag propagation to track the flow of transactions from flagged accounts. Newly-mined Ethereum transaction metadata is imported via a Server-Sent Events data source.
