ParallelCoin Network Specifications
The original version of the Parallelcoin client and wallet lives inside pod here: https://github.com/p9c/pod/tree/master/legacy.
This project was immediately abandoned by its original creator shortly after release in early 2014. In June, 2015, users on the Bitcointalk forum, specifically initiated by @marcetin who is also here on github: https://github.com/marcetin/, started planning an upgrade for the chain.
Some time later, in mid 2018, after searching for developers to update the network, they found Loki to build an upgrade to the network.
The original version has a serious bug with its difficulty adjustment that makes it unable to adjust to large changes in hash power, and over time this has led to a steady lengthening of the block time, as at 2019 it was already around 12 minutes.
So, the Plan 9 Hard fork was begun:
Phase one is both the debut of the developers and administrators working on the project, their current career thesis, and aiming to render the ParallelCoin blockchain up to date as a simple payment network with limited currency issuance, and improving security against malicious miners and promoting maximal wide distribution of the tokens to improve the 'currency area' driving adoption.
- long division based proof of work (CPUs have the fastest dividers)
- shorter block times - 68 seconds (to improve distribution with big miner userbase)
- 9 different, prime based parallel block schedules with proportional rewards (to reduce timing attack surface)
- multicast based mining control system for mining farms (preshared keys just like wifi)
- cross platform GUI wallet with access to all necessary features (windows, mac, linux, bsd at first, then android and iOS)
Phase one is about taking the token from Parallelcoin network, upgrading its payment processing network protocol with the above improvements, and starting to introduce users to the idea of a blockchain system as being the centre of an operating system.
In this phase we completely rewrite the protocol using all of the best available knowledge to create the first fully asynchronous blockchain system that is built to be extended and can integrate and encompass every other platform into its base should the users want the integration. This allows instant cross-chain atomic swaps from the ground up, and introduces the idea of a universal blockchain framework that forms a protocol for integrating other protocols. Hence the reference to the Borg.
