The goal of this post is to aid in choosing a permissioned blockchain project for different use cases. I’ve compared different permissioned blockchains. Even though most of the projects look alike, they all shine in different ways.

As a prerequisite, you’ll need to know what a permissioned blockchain is and what the use cases are. For starters I recommend this and this post.

A private blockchain is useful when you have an organization where

the members of the organization are geographically distributed, and cannot trust each other completely, there is a documented history of corruption, specifically one that goes undetected for many years, there is no possibility of establishing a centralized control, whom everyone trusts, like a “head office”, “president” or “company servers”.

Permissioned Blockchain has different use cases such as supply chain, payments, custody, credit swaps, commodities, micro lending, escrow, charity, music publishing and much more.

In other words, the security of a public blockchain like Bitcoin comes from Proof of Work, which makes it mathematically impossible to fake or reverse transactions without colluding miners. On the other hand, the security promises of distributed ledgers and private blockchains are only as good as the honesty of the entities validating the transactions. There are no mathematical guarantees behind the irreversibility of transactions in a private blockchain.
