Spring Forward 

Growth requires challenge. 

There was plenty of such fuel over the last several weeks, challenging our community to run a functional and fair network that is more poised for growth. This announcement will detail what has happened, how we addressed it and how, along the way, we solved a number of different problems and improved prospects going forward.

On 9 April 2022, the 0L Network halted. Multiple factors combined to create the incident; factors that started small and cascaded until the entire network ceased to produce blocks. While the detailed causes and the technical forensics have been discussed at length in our community meetings, the important point to raise here is that the halt was avoidable – or rather would have been avoidable – had a sufficient number within our validator community been more attentive to their machines and taken steps in a timely fashion.…

Research Report: Decentralizing Permissioned Blockchain with Delay Towers

This report, published 18 March 2022, looks at the Delay Towers mechanism that was pioneered and deployed in the 0L Network.

The article was co-authored by Shashank Motepalli and Hans-Arno Jocobsen of the University of Toronoto. We quote the original synopsis below:

Growing excitement around permissionless blockchains is uncovering its latent scalability concerns. Permissioned blockchains offer high transactional throughput and low latencies while compromising decentralization. In the quest for a decentralized, scalable blockchain fabric, i.e., to offer the scalability of permissioned blockchain in a permissionless setting, we present L4L to encourage decentralization over the permissioned Libra network without compromising its sustainability.…

Future-Proofing the Economics of Blockchains (Pt. 3)

Incentives are hard. There are many different stakeholders in a healthy economy and the needs of those stakeholders can be a moving target. Advanced mechanisms are employed to address the trade-off between clear rules and adaptive capacity. Polycentric programs with community wallets provide a means of voluntarily contributing to capex, while thermostatic security dynamically rebalances validator rewards based on validator count in order to manage opex.

Delay Towers – Implementation on BFT (Pt.3)

Delay towers provide many benefits to BFT networks, including diverse distribution of participants, Sybil resistance, eco-friendliness, determinism, and others. This post delves into one specific implementation of delay towers and its integration with a high-throughput BFT network for bootstrapping purposes, and offers it as a strategy to achieve the goals of a free and fair chain launch.
