Systems and methods for streaming classification of distributed ledger-based activities are disclosed. In one embodiment, a method for streaming classification of distributed ledger-based activities may include: receiving, at a detection computer program executed by a server and from a distributed ledger network, information for a plurality of transactions; receiving, from a database and at the detection computer program, node information that identifies a plurality of nodes as involved in illicit transactions, as being involved in licit transactions, or unknown; applying, by the detection computer program, exponential time sampling to sample labels and associated features; training, by the detection computer program, a classifier; receiving, by the detection computer program, a streaming transaction from the distributed ledger network; predicting, by the detection computer program, a classification for the streaming transaction using the trained classifier; and outputting, by the detection computer program, an alert based on the prediction.
