About Obsidian

Obsidian is a proof-of-stake (PoS) blockchain running since mid-2017.
Our flagship mobile application is the Obsidian Secure Messenger, an anonymous, encrypted communications application which makes use of the Obsidian blockchain.

Improvements across all things Obsidian are being worked on, and feedback is highly encouraged. We seek further collaboration from developers, organizations and blockchains.

Team Obsidian

OSM is developed and maintained by a globally active development team.
Many individuals, groups of developers, advisors, agencies, community members and contractors have helped us across all areas of Obsidian.

The current active Obsidian team maintains the Obsidian blockchain, wallets, and other related technologies. If you would like to join us, get in touch on our community channels.

Proof of Stake

Staking is a process which ODN holders can easily implement in an official Obsidian wallet, and is a method used by proof-of-stake (PoS) blockchains to secure the network.

In very simple terms, staking can be thought of in a similar way to mining, in that staking periodically generates coins as a reward to the wallet, (also known as a node), that is staking.

Low power and cost

You do not need a supercomputer or specialist graphics card to stake Obsidian coins. In fact, you can stake ODN on a low-cost Raspberry Pi. A very small amount of energy is required to facilitate staking Obsidian coins.

ODN rewards

The more ODN you hold in your wallet, the more staking rewards you will earn. It does not matter how powerful your machine is.
