The POA Product Suite

A full overview of the POA Network product suite development tools and how all the tools came together to create **xDai Stable Chain**.

The POA Product Suite: Moving The Ethereum Protocol Forward

[image] In a world of single-product projects, POA Network sometimes gets lumped in with the rest of the crowd. While the POA Core network was our first live product, we’ve since expanded to offer a suite of products designed for the Ethereum ecosystem. With over 70 Github contributors and 90+ repos, POA strives to develop products that push the Ethereum protocol forward. From innovative sidechains, to open-source explorers used by some of the biggest players in blockchain, to interoperability…

xDai: The Birth of The Stable Chain

Read about the incredible xDai journey so far: how xDai was born from of a causal conversation at ETHBerlin, its adoption and usage as a peer-to-peer payment focused network with Burner Wallet, and most exciting of allm future plans with DPoS and multi-chain staking.

xDai: The birth of the stable chain

Igor jotted down his idea on a napkin at the dinner table. Bridge an ERC20 stable coin to its own sidechain - the bridged version becomes the native coin of the new sidechain. This would create a stable native coin blockchain. And just like that, on the back of a napkin, the foundation of the xDai Stable Chain was born.

xDai Validators: Decentralizing Stable Chains

Read on below to find out what the ten amazing initial validators have to say about the future of xDai and why they are excited about decentralizing the stable chains.

xDai Validators: Decentralizing Stable Chains

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.

xDai Stable Chain: Introducing the $DPOS Token and Multichain Staking

The new upgrade of xDai to POSDAO staking based consensus comes with new ideas and innovations. With the introduction of the two token model, we will have xDai and a new staking token: $DPOS. With $DPOS, users will be able to stake and delegate on xDai Stable Chain AND all other xStableChains launched. Read more about $DPOS , Multichain Staking, Delegating, Pools and the building blocks of stablechains .

xDai Stable Chain: Introducing the $DPOS Token and Multichain Staking

Before we explain multichain staking in detail, however, we’ll start with a few caveats about xDai and POSDAO, and introduce the new staking token that will make its debut as part of this upgrade: DPOS (referred to as $DPOS for the remainder of this post to avoid confusion with the staking consensus, DPoS).

Reliable Randomness: Bringing on-chain entropy to the xDai Stable Chain

Randomness is vital to a blockchain, and difficult to achieve within the protocol. POSDAO on the xDai Stable Chain will offer the first Ethereum implementation of Proof of Stake, and on-chain randomness is a key feature of this implementation. Check out the post below to see what strategies we use to generate reliable randomness in the new POSDAO algorithm, and why on-chain randomness is important as a key feature in POSDAO and xDai.

Reliable Randomness: Bringing on-chain entropy to the xDai Stable Chain

[image] 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 so…
