The members of the Association are responsible for governance decisions, monitoring the operation of the Diem payment system, projects built on the Diem blockchain, and providing grants. Facebook aims to have 100 members in this association at launch.

Is Diem a Cryptocurrency?

Diem is built on top of blockchain and it uses cryptographic technology. However, the term often implies specific properties that the coin does not currently have. In summary, according to many reviewers, it would be more accurate to call Diem a cryptocurrency.

How does Diem work?

Diem Blockchain is a blockchain be licenced, form the backbone of this payment system. This makes it different because blockchains like or license is not required.

This means that anyone with an Internet connection is free to access, transact with, or build upon them. There isn't anyone (or anything) controlling access to these blockchains.

However, this will not happen with a licensed blockchain. To use it, you will need the permission of the person who is controlling the network. Or more specifically, the apps you use will need special permissions. Diem is a permissioned blockchain, which also means it won't be able to mine or stake to validate transactions, like many other blockchains.

Instead, it will rely on a set of licensed validators (members of the Diem Association) to validate transactions. According to its creators, Diem is convertible to () after the first five years.

However, this is a long time for a new platform to launch. So, why didn't Diem use right from the start? Facebook explained this choice in the white paper. In that, from their point of view, there is currently no permissionless system that can support billions of people trading at the same time.

Decentralized or Centralized Diem?

According to many experts, licensed blockchains cannot be as decentralized as unlicensed “peers”. After all, they are more like traditional corporate databases. In this sense, Diem is not as resistant to censorship as and other cryptocurrencies.

Since validators need to be members of the Diem Association, the network can become relatively centralized. However, controlling and regulating which applications can interact with the distributed ledger can be difficult. there are other advantages. For example, it can be easier to rule out malicious and phishing apps.

Diem payment system

The Diem payment system supports several prices with fiat currencies like USD, EUR, GBP. These coins work similarly to the stablecoins you may already know in that their value is derived from a reserve known as the Diem Reserve.

This reserve is made up of cash, cash equivalents and short-term government securities. In addition, the Diem payment system will also support a multi-currency currency called the Diem Dollar. It is a composite of all other stablecoins and is backed by a basket of assets that back it up.

You can think of it as a stablecoin of stablecoins (and possibly other assets, such as securities). The idea is that different forms of collateral can protect it from volatility - an important aspect for something that wants to act as a form of payment.

According to the plan, Diem will also assist smart contrast through a programming language called Move.

Can Diem Replace Bitcoin?

For now, it's clear that Diem and Bitcoin are fundamentally different and they will most likely co-exist in the future. While both can be thought of as electronic payment systems, they serve different use cases.
