Stampery Blockchain Timestamping Architecture (BTA) - Version 6
This addresses the need for efficient and secure data certification in blockchain applications, though it appears incremental as a version update to an existing architecture.
The paper tackles the problem of timestamping and certifying large volumes of data on blockchains, achieving scalability and cost-effectiveness while ensuring verifiable existence, integrity, and ownership without disclosing original data or requiring certifier intervention.
A method for timestamping, anchoring and certification of a virtually unlimited amount of data in one or more blockchains, focusing on scalability and cost-effectiveness while ensuring existence, integrity and ownership by using cryptographic proofs that are independently verifiable by anyone in the world without disclosure of the original data and without the intervention of the certifying party.
