Blockchain
Seals is a blockchain-based solution for digitalising the document exchange for international trade.
Authentic documents at your fingertips!
Store and bring your certificates with you for easy validation and control wherever you are.
Seals is a public distributed network to certify and verify international trade documents
Strategy Object’s Seals is a blockchain that enables authorities to issue their official electronic documents, certificates, permits, which are then verified by required authorities worldwide.
Mobile
The Seals network is accessible via a mobile application available on both Apple Store and Google Play.
Online verification
Documents can be controlled online via the Seals.app, to verify the authenticity of a document and its issuer as well as view its content.
Conceived for Institutions
The Seals network allows institutions to upload their documents to the blockchain so that they can be validated by other authorities.
Immutable
Nobody can alter the actions performed on a document.
Decentralised
No need to trust one specific entity. All participants become source of truth.
Authentic documents
A document that the blockchain endorses to be genuine and official, that is intact, not tampered and issued by a well-identified entity in the blockchain.
Selective Disclosure
Users can share portions of documents, and the blockchain can verify they are genuine and official.
Partial Consumption
The Seals blockchain can manage quantities and their write-offs.
Information is publicly verifiable
The documents validity can be verified publicly online.
Substrate Client for Java
Strategy Object has been developing and maintaining the Substrate Client for Java, which enables Java based applications to interact with a Polkadot or Substrate network.
Substrate Client JavaJava 8 or higher
The Substrate Client for Java will be compatible with Java 8 and higher. Covering a great range of Java versions will make this library available and usable for as many projects as possible.
Non-blocking API
The API is designed to be non-blocking. It will not engage or block resources to wait for responses from a node. This is crucial especially when working with web sockets.
Declarative approach
We use annotations and code generation techniques to reach our project’s main goals, which let users organise their code similar to the one in the pallet they are interacting with.
Tests run with Substrate node
All API methods related to the Substrate node will be tested for operability and compatibility.
