Author: Matthias Geihs The Perun Framework is a toolkit for increasing a blockchain’s transaction throughput and enabling transactions across blockchain networks. In addition to supporting Ethereum and Cosmos blockchains, the Perun Framework now also supports Polkadot blockchains. The development of the Polkadot backend is supported by the Web3 Foundation through…

We showcase Erdstall applications and introduce our Nifty Erdstall Demo for you to test. By leveraging a TEE-based Plasma system (Erdstall), we bring highly scalable and customizable functionality to the second layer. With arbitrary programmability and execution within a secure enclave (Intel SGX) we can guarantee untampered execution of arbitrary…

A few years ago, blockchain scalability seemed to be the greatest challenge in the development of the blockchain space. This is not the case anymore because many projects created their own solutions. As a consequence, many new ecosystems emerged separately and independently. The resulting silos were not exactly the interconnected…

Author: Oliver Tale-Yazdi Perun Network is developing a blockchain agnostic state channel framework in the form of a golang library: go-perun. After successfully implementing a backend for Ethereum, we are now looking at Polkadot and have received a Web3 Foundation grant for the project. We opted to implement the Polkadot…

In this blog post, we introduce a prime use case for blockchain and Perun State Channel technology in logistics called Platooning. Platooning is a new method of driving, where multiple vehicles are linked together to a convoy. It increases economic and ecological efficiency due to slipstream effects and increases the…

Rollups are an emerging technology for scaling the Ethereum blockchain. Applications deployed on a rollup benefit from reduced transaction costs and faster transaction confirmation times. On the downside, rollups require the users to lock up funds which can then only be used within the rollup. For some rollup techniques, it…

We introduce a new hybrid approach for developing NFT marketplaces that allows both novice and advanced users to fully use all NFT features while still ensuring ease-of-use, low fees, scalability, flexibility, and security. Non-fungible tokens or NFTs have risen in popularity over the past few months. The power of NFTs…

Previously, we introduced collateralized channels and discussed how they can enable peer-to-peer payments in an offline setting. In the following we show how collateralized channels on Ethereum are implemented using the Go-Perun library. We start with a brief introduction to Go-Perun and then go through the main aspects of the…

Payment channels enable fast local micro-payments on top of a comparatively slow global transaction backend. However, opening a payment channel typically requires that clients are connected to a global transaction backend. Therefore, payment channels cannot be established when clients are offline, e.g., when going through a rural area with low…
