Abstract
Methods and systems for distributed ledger-based digital content distribution chain tracing may comprise receiving an indication of a content asset and an indication of a first user associated with the content asset. A first distributed ledger record may be stored and/or created on a distributed ledger comprising the indication of the content asset and the indication of the first user. A second distributed ledger record may be stored on and/or created on the distributed ledger comprising an indication of a second user associated with the content asset. A version of the content asset may be generated comprising one or more frames having a digital marker. The digital marker may comprise an indication of the first user. At least one of the first distributed ledger record or the second distributed ledger record may be determined based on the digital marker as part of tracking or tracing the content asset.
