Embodiments provide traceability of edits to a document, i.e., a verifiable and immutable provenance chain for the document. Systems and methods enable traceability of edits, by encoding, for states of the document, a fingerprint (e.g., a cryptographic hash of the document's contents) and an edit history within a block written to a distributed ledger (e.g., a blockchain). The ledger is maintained via a self-organizing peer-to-peer distributed ledger network. Once added to the ledger, the contents of a block (e.g., the document's fingerprint and edit history) are immutable and the integrity of the edit history encoded in the ledger is secure. The algorithm that generates the fingerprint is sensitive to edits of the document. The non-corruptible fingerprint encoded in the ledger is employable to detect any edits that are not included in the encoded edit history and/or inconsistent with a currently available version of the document.

Traceability of edits to digital documents via distributed ledgers

Embodiments of the present invention provide systems, methods, and computer storage media directed to reducing a size of a blockchain. In implementation, upon identifying an indication to reduce a size of a blockchain, a set of blocks to remove from the blockchain can be determined. The set of blocks can then be removed from the blockchain to reduce the size of the blockchain thereby reducing the amount of memory used by the blockchain.

Non-destructive collaborative editing may include a node among a plurality of nodes in a distributed collaborative environment receiving an input indicating a change regarding a displayed image. The node may receive another input to finalize the change. In response to the other input, the node may generate a rendition that reflects the change applied to the image without replacing an original version of the image. The rendition may include a thumbnail and a rendered preview of an adjusted version of the image based on the change. In one embodiment, textual information that describes a change regarding an image of a plurality of images may be received from a node of a plurality of nodes in a distributed collaborative environment. The textual information may be stored. Application of the textual information to an image may result in a modified version of the image in addition to the original version.

Non-destructive collaborative editing

Content in a content-aware mesh may be accessed and/or manipulated. In one embodiment, a node may receive access to each of a plurality of images that are distributed among at least two nodes of a mesh. The at least two nodes may not be part of the same service. Accessing to each of the images may be performed without the node locally storing all of the images. The node may display an image of the plurality of images via a uniform interface without indication as to which of the nodes the image is stored on.
