It is the history of the product which makes the difference in value estimation, provided that the documentation is transparent and certain. MyLime solves the problem of how to protect the history of a product. A tracking and validation process was developed based on blockchain technology: a digital identity card in which content is grouped into encrypted blocks and chained in chronological order. Not only is the timing important, but also the geolocation of the recorded information. This data is immutable: once entered, it cannot be changed or deleted, thus guaranteeing the authenticity of the asset and therefore its value.
