Year in review — 2022
by nion | 23. Jul 2023 | year in review, research, innovations

In the "Year in Review 2022" article, we delve into the Nion protocol's journey, a secure and scalable solution for decentralized infrastructure. Our dedicated team worked on key improvements, focusing on networking enhancements, verifiable delay functions, and efficient application migration using CRIU. As we set our sights on the future, we continue to push the horizons of decentralized technology through innovative research and development.


P2P Networking in NION
by aleksandar | 30. Aug 2021 | blockchain, p2p

Nion Network is introducing P2P networking capabilities to enhance its blockchain scalability. The traditional flood-based algorithm, though simple, can result in redundant network utilization and slow information dissemination. Nion Network is implementing a new algorithm that utilizes proof of stake and a binary tree structure for routing messages, resulting in faster and more secure transactions. This new feature also allows for increased privacy as nodes can transact directly without intermediaries. Join the Nion Network community to experience the future of decentralized finance with this innovative technology.


Nion Network — The Genesis
by nion | 20. Jul 2021 | genesis, blockchain

Nion Network is a revolutionary new blockchain platform that aims to address key issues in the decentralized space, including language heterogeneity, resource allocation, and verifiability. The platform utilizes a permissioned blockchain with a federated vote-based consensus mechanism, where nodes not only contribute to security and consensus but also share their resources by running containerized applications. The new version of Nion Network will be a permissionless network with Proof of Stake consensus mechanism, stateful container migration and fixed network parameters. Join the Nion Network community and be a part of a  more efficient, decentralized world.

Run-time application migration using checkpoint/restore in userspace
Status: Pending peer review

This paper presents an empirical study on the feasibility of using Checkpoint/Restore In Userspace (CRIU) for run-time application migration between hosts, with a particular focus on edge computing and cloud infrastructures. The paper provides experimental support for CRIU in Docker and offers insights into the impact of application memory usage on checkpoint size, time, and resources. Through a series of tests, we find that the time to checkpoint is linearly proportional to the size of the memory allocation of the container, while the restore is less so. Our findings contribute to the understanding of CRIU's performance and its potential use in edge computing scenarios. To obtain accurate and meaningful findings, we monitored system telemetry while using CRIU to observe its impact on the host machine's CPU and RAM. Although our results may not be groundbreaking, they offer a good overview and a technical report on the feasibility of using CRIU on edge devices. This study's findings and experimental support for CRIU in Docker could serve as a useful reference for future research on performance optimization and application migration using CRIU.
