Over the last few months, we have been working hard on a new interoperability protocol design. Since launching the original POA20 Bridge on May 2018, POA has been continuously improving and expanding the technology to explore new use cases for the TokenBridge. Interoperability is at the core of everything we do in POA Network, and today we’d like to discuss our latest interop development: the Ethereum to Binance Chain Bridge (ERC20 — BEP2 bridge).

Binance Chain is a blockchain software system developed by Binance and its community. It is a blockchain which currently houses Binance DEX, a decentralized exchange with…

In our recent history of xDai post, we discussed the origins of the xDai Stable Chain. When it began, xDai was highly centralized — in fact POA Network was the one and only validator! This immediately shifted as several new validators were introduced, and POA Network’s on-chain governance model brought further decentralization to the protocol.

A set of on-chain governance tools allows current validators to propose and elect new validators as they see fit. Validator candidates introduce themselves and make their case for becoming a new validator, the current validators discuss their merits and ask questions, and if they decide…

Q) What do computer mouse movements, lava lamps, avalanches, and radioactive decay have in common?

A) They have all been used as sources of real-world randomness.

True randomness is impossible to achieve using only a computer. Input A always produces Output B, and this deterministic logic is repeatable and predictable. A random number should be unpredictable and independent of previous results, leaving applications to look outside of themselves to seed algorithms with real-world sources of randomness.

Public blockchains, however, are designed to function in a…

This article is part 3 in a series detailing POA Network’s efforts to build a resilient blockchain consensus algorithm, known as Honey Badger Byzantine Fault Tolerance — or HBBFT for short. Check the first and second article in the series for a more in-depth description of the protocol and how it works.

Note: Our Honey Badger BFT and Threshold Cryptography implementations have both undergone extensive security audits to ensure safety and cryptographic integrity. The results are available here:

As detailed in our previous post, Honey Badger BFT (HBBFT) is a robust, asynchronous consensus protocol…

POA Friends,

As we wrap up this action packed year, we took some time to reflect on the incredible journey we’ve had since we launched our mainnet and we want to share some of the exciting initiatives we have coming for you next year as well as the our most recent updates and news. Lets jump right into it!

We’re excited to announce we have already on-boarded 3 additional entities that are playing the role of a validator for both the xDai Chain and the xDai Bridge. By including POA Network’s own validator node, we now have a total of 4 active validators for this new network! Each of these entities have successfully gone through the Ceremony event that takes place when on-boarding new validators. In simple terms, this event includes distributing the necessary keys, setting up the actual nodes, and having the correct configuration in order to effectively serve as a validator of the network.

Each entity that’s…

The Constantinople Hard Fork is scheduled to take place on the Ethereum Mainnet in mid-January 2019, at block 7,080,000. In this post, we discuss the upcoming changes to the protocol and describe how POA Network, Consensys, and Compound Finance are collaborating to develop Mana-Ethereum, a new open-source Ethereum client.

This week the Mana-Ethereum project celebrated a milestone — a full sync with the Ropsten testnet! This is important because Ropsten is currently running Constantinople, a new hard fork with a planned January release on the Ethereum mainnet. …

We’re happy to announce it’s been 1 full year since POA Network launched its mainnet!On December 15, 2017 we launched our network with 12 validators and a vision of a high-speed, low-cost network that would provide tools and transaction efficiency for the developer community as well as the general public. Fast forward one year, and we’ve grown to support a new interoperability protocol, amazing DApp development and integration, and a thriving proof-of-authority consensus process which includes 23 validators, all of whom play an active governance role in the network.

For POA Network, 2018 was a year full of constant development…

Hey Friends,

This past month’s focus for POA Network has been to BUIDL, BUIDL, and BUIDL. Our team spent a full week in Prague to not only present at Devcon but also host various conferences leading up to it. We also have some great updates to our core technology. Let’s dive right into it!

What’s New with POA

As many of you are already aware, in late 2017 we released the open source Token Wizard to the public to simplify the technical setup that comes with crowd fundraising smart contracts. The Token Wizard, built on Authio platform, provided a unique interface that allowed users to simply enter their fundraising parameters resulting in a much more efficient crowd fundraising setup process.

The Token Wizard is a free tool that has been used by thousands of projects, has over 300 stars on Github, and has been one of our most used projects.

As per our technical roadmap, we were planning…

POA Network

Public platform for smart contracts. An open Ethereum sidechain with Proof of Authority (PoA) consensus by independent validators.
