Proof-of-Authority (PoA) module

[brandoncurtis]

Summary

A Cosmos SDK module for establishing a Proof-of-Authority (PoA) chain.

This is a tracking issue that people interested in this topic can reference and subscribe to for updates.

Problem Definition

The Cosmos intro README states that it is possible to build both Proof-of-Stake (PoS) and PoA chains using the Cosmos SDK.

A purpose-built PoA module has been requested, asked about, and even proposed as a hackathon project in a few places:

• https://forum.cosmos.network/t/poa-proof-of-authority-setup/2606
• https://blog.cosmos.network/understanding-the-value-proposition-of-cosmos-ecaef63350d
• https://www.hackathon.com/event/chain-accelerator-is-organizing--for-tendermint-tendermintcom-and-universite-paris-dauphines-fintech-chair--a-hackathon-on-april-13rd-14th-2019-55403776186

Proposal

Create a Cosmos SDK module that supports the creation of PoA chains.

There’s already a PoA module on the cosmos/modules repo

@marbar3778 is this still under development?

I was waiting for gentx to be generalized, but doesn't seem like this is a priority so will duplicate the logic in the module. I would also like to finish it once 0.38 is out, this is projected for this week. So next week ill find some time to push it over the finish line

here is the pr for reference: cosmos/modules#5

Closing this issue as the question was resolved by @marbar3778. Please open a new issue on cosmos/modules if you consider it necessary

I wasn't able to find any PoA module for the Cosmos SDK. I'm trying to at least understand why some development were started and then stopped apparently without notice.

Maybe you can clarify what happened to PoA development?

Hi @PinkFromTheFuture,

I currently have the same issue as you, I need a PoA module.
PoA seems to still be in the incubator do I have to code it by myself as this one is not stable?

I think Strangelove is working on one: https://github.com/strangelove-ventures/poa

@Bedjes-Studio Yep! We have a working concept here in this PR: strangelove-ventures/poa#34

This will sit on top of the staking module to give backwards compatibility with UIs & make it easier to migrate from POA->POS in the future. This also gives us all the security & validation benefits of staking while making it permissioned

please DM me if you have any specific use case needs not covered
