The application may adapt its protocol in response to proposed improvements and market feedback but all changes must be decided by consensus of its users.
The application's data and records of operation must be cryptographically stored in a public, decentralized blockchain in order to avoid any central points of failure.
The application must use a cryptographic token (bitcoin or a token native to its system) which is necessary for access to the application and any contribution of value from (miners / farmers) should be rewarded in the application’s tokens.
The application must generate tokens according to a standard crytptographic algorithm acting as a proof of the value nodes are contributing to the application (Bitcoin uses the Proof of Work Algorithm).

MIT Chainanchor ChainAnchor addresses the issue of identity anonymity and access control within shared permissioned blockchains. Anonymity of entities is achieved using a zero-knowledge proof protocol. Entities have the ability to register one of more transaction public-keys which they self-generate. ChainAnchor provides unlinkability of transactions signed using these registered keys.

A query is divided up into sub-queries and sent to only the relevant K nodes (out of a total of N nodes in the network.

Information architecture for a certification and chain-of-custody system on the blockchain Here we show how existing certifications and audits of supply chains can take on a new guise implemented on the blockchain.
There are six different types of actors involved in our exemplar set-up: Producers (e.g., a cotton grower); Manufacturers (e.g., a maker of fabric or jeans); Registrars, which are organizations that provide credentials and a unique identity to actors (e.g., an accreditation service); Standards organizations, which define the rules of a certain scheme (e.g., Fairtrade); Certifiers and auditors, which are agents — usually separate agents, to maximize security — that inspect producers and manufacturers and verify certain standards, like annual production capacity; and Customers, the buyers of products all along a supply chains, including the end consumer.
Below we explain the principal architecture. The architecture consists of a number of modular programs. Registration program. Blockstream. Distributed Ledger.
