What is ProvenDB
ProvenDB layers on top of a standard database engine adding
core blockchain characteristics. The resulting database
respects all usual database “CRUD” operations but also
leverages the blockchain to provide an immutable, tamper-proof
history of the data stored within the database.
ProvenDB can generate proofs for a database version or single document. Although only the hash for a complete version is anchored on the blockchain, ProvenDB can supply a Merkle tree path which provides cryptographic proof that a given document was included within the blockchain hash. This way, users can obtain proofs for individual documents that can be validated without the need to access any other documents within the database.
ProvenDB presents a MongoDB compatible API to the database user. Every change to the database creates a new logical version within the backend database. The user can view these older versions at any time. The database user requests a proof be placed on the blockchain for a specific version. The version can be used to prove the timestamp of the entire version or any document in that version.

How it Works
Information stored on the public blockchain is
immutable - it cannot be changed or deleted. By storing
cryptographic signatures of the contents of your document on
the blockchain, we can prove that the document existed at a
specific time and that you uploaded it. This proof is
mathematically indisputable and is increasingly recognised in
legislation in court.
Only the cryptographic signature hash is stored on the public blockchain and cannot be used to view your document contents. Your document is stored securely in the ProvenDB database and cannot be seen by anyone without your permission.
You can share any document with its blockchain proof if you want to assert document ownership or timestamp. You can also publish a document, and it’s proof publicly to declare your ownership or timestamp to the world.

ProvenDB bridges the gap
ProvenDB bridges the gap between a fully functional database service
and a blockchain integration.
A fully functional database service
MongoDB compatible
Normal throughput and latency
Rich query and database operations
Strong privacy
Blockchain integration
Versioning of data
Immutability of past versions
Tamper detection
Point in time history
Complete data provenance
Benefits of using ProvenDB
Here is a look at some of the benefits of using ProvenDB
Blockchain Proven
Data in ProvenDB is anchored to the public Bitcoin blockchain.
The existence and provenance of the data are cryptographically
proven and tamper proof. This makes ProvenDB an excellent choice
for applications that store legally significant data such as
accounting systems, intellectual property solutions and similar.
Immutable Versions
Older versions of data can be maintained indefinitely. You can
view older versions of the database and track the changes to
database items. However, unlike the blockchain, data can be
“forgotten” to comply with Right to be Forgotten regulations,
and unedited versions can be “compacted” to save space and cost.
Economic and Performant
Storing small amounts of data on the public blockchain is
expensive. ProvenDB storage costs are similar to a standard
database and keeps the data in a conventional data store.
Blockchains support a handful of transactions per second.
ProvenDB can process transactions and submit proofs to the
blockchain at database speeds.
Productive
Blockchain programming is complex and esoteric. ProvenDB is
compatible with the developer-friendly MongoDB database,
allowing developers to develop blockchain enabled applications
easily or to blockchain enable existing applications.
