people strung cable, wrote code, created rules, built organizations, and formed alliances. Self-sovereign identity (SSI) has similar needs and meeting them won’t happen just because we define nice open source software. A functioning network for an identity metasystem is a social system, and building it requires a means of building coherence to align the actions of people and organizations. We created the Sovrin Foundation to do that. Sovrin is a global, decentralized self-sovereign identity network based on open-source distributed ledger technology. It is based on the Hyperledger Indy Project hosted by the Linux Foundation and licensed under Apache 2.0. It allows people and organizations to create portable, self-sovereign digital identities. It uses a public permissioned ledger governed by the Sovrin Foundation. The ledger is a cryptographic database that is provided by a pool of participants worldwide. The Sovrin Foundation is a non-profit organization established to administer the Governance Framework governing the Sovrin Network, a public service utility enabling self- sovereign identity on the internet. The Sovrin Foundation is an independent organization that is responsible for ensuring the Sovrin identity system is public and globally accessible.
MATTR
MATTR believes that for the next generation of the internet to be successful an open and interoperable ‘web of trust’ must be created. MATTR have been focused on building to open standards and the principle of choice in the marketplace. MATTR contributes extensively to a number of specifications and emerging standards for protocols, components, and data formats across the Decentralised Identity ecosystem.
Creating a “web of trust,” allowing people and organisations to protect what is theirs, easily prove who they are, and share only what they need to get things done online. - Claire Barber CEO of MATTR
Distributed Ledger
A distributed ledger is a database of information held and replicated independently by participants in a network called nodes. A blockchain is a specific subtype of a distributed ledger that provides a more secure distributed consensus. It is also called a shared ledger or referred to as distributed ledger technology. It can be a single ledger having layered permissions or consisting of multiple ledgers maintained by a distributed network of nodes. It is a consensus of shared, replicated and synchronized digital information geographically spread across multiple sites or institutions. Updates on a distributed ledger can be independently created and recorded and are voted over to ensure a majority consensus is reached Depending on whether the network participants or nodes
need permission to access and make changes to the ledger makes the distributed ledger public or private and permissioned or permissionless. Distributed ledgers operate to organize data on a broad structure, blockchains operate much more specifically to organize data and update entries.
By design, a blockchain is resistant to modification of the data. It is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.
Blockchain is a technology used for distributed ledgers and is suitable for many applications, consequently blockchain is also associated with crypto currency including Bitcoin, but the usage is specific to the application.

In the remaining part of this article to allow understanding and application of the technologies presented I will describe some scenarios with application to the IIMS and marine surveyors. In the Information Technology (IT) we refer to these real-world scenarios as “Epics” with associated “User Stories” to allow a better understanding and application of the technologies presented.
