What is Optical Bitcoin (oBTC)?


Optical Bitcoin [oBTC] is a Bitcoin fork using oPoW, a proof of work algorithm for optical computers developed by PoWx (www.powx.org).

We originally published an experimental net in March https://bitcointalk.org/index.php?topic=5324899.0

The network has proved stable after the initial adjustment to the genesis block difficulty. We're excited to announce that going forward, oBTC is running as the mainnet, not an experimental net.

What has been changed in the Bitcoin codebase?

The Proof of Work has been swapped for oPoW and the halving period has been doubled.

What is oPoW?

Optical Proof of Work, a hashcash derivative that is compatible with existing optical computers developed for AI.

Who is Behind PoWx?

The founders of PoWx are Michael Dubrovsky and Bogdan Penkovsky, however, there are many contributors. More details are available on Github: https://github.com/PoWx-Org/obtc-core/blob/master/README.md

Current State of the Blockchain


The chain was fair-launched on bitcointalk as a live experimental net with an empty genesis block and has been running for some time now with miners all over the world contributing hashpower. The current block height is 30111.

Project Goals


We outlined the value proposition of oPoW in our paper, blog posts, etc. over the last several years. The long-term goal is to shift the PoW ecosystem to low-energy computing, making the hashrate more resilient and enabling a much broader geographic distribution of mining. Please see www.PoWx.org

Disclaimer

This is an experimental network. We’re hoping that it’s usable and stable as is based on our testing, however, if you mine it, note that you are doing so at your own risk. We may have to relaunch the network in the future and coin balances may be lost. We will be posting updates on the state of development and critical upcoming milestones.
