The best thing about Stampery is its ability to provide a tamper-proof and immutable record of the authenticity and integrity of digital content. It uses blockchain technology to create a unique cryptographic signature that verifies the existence and ownership of a specific digital file at a particular time. This can be useful for a variety of purposes, such as proving the authenticity of a legal document or certifying the originality of a piece of art.
