1. Who is the interested party for this collateral application?
xDai Chain team https://www.xdaichain.com/media/xdai-dev-team
2. Provide a brief high-level overview of the project, with a focus on the applying collateral token.
The xDai chain is a stable-payments L2 sidechain, providing fast, secure transactions with full interoperability and compatibility to the Ethereum Mainnet. It features a dual token model, where xDai is the native and stable transactional token bridged from a stable token (Dai) on Ethereum, and STAKE is the underlying Ethereum mainnet asset providing security and governance capabilities. This collateral application is for the STAKE token.
STAKE is a multi-chain ERC20-based staking token. It resides on the Ethereum mainnet and is bridged to the xDai chain via OmniBridge to provide network security. It supports Delegated Proof-of-Stake consensus (POSDAO), secures the payment layer and prevents malicious activities. Though initially designed for xDai, it can also be implemented in other blockchain networks for staking and governance.
STAKE is also designed as a governance token, providing chain and bridge validators the opportunity to vote on network parameters such as fees structures and staking minimums. There are plans to extend this capability to allow stake-weighted voting on transaction priority and micro-governance decisions. These efforts are evolving as public staking launches on the xDai chain.
While STAKE is the security and governance token for the xDai chain, the xDai native token is used for stable and predictable transactions, payments, and fees. It is bridged from Dai, meaning all xDai users are essentially Dai users. As of 2020-12-03T21:00:00Z, there is more than 2M Dai locked in the xDai bridge contract and circulating as xDai on the xDai chain.
In November 2020, xDai transactions nearly doubled Dai transfers.
Total Dai Transactions: xDai: 1,100,784 Ethereum: 572,396
Average Dai tx/day: xDai: 36,693 Ethereum: 19,080
3. Provide a brief history of the project.
xDai stable chain was created in October 2018 with its xDai stable coin. The idea was to build a stable blockchain with a native stable coin that could be bridged directly to a sidechain, eliminating high transaction costs and volatile prices and remove the additional gas token.
More than 2 years later, the xDai chain is currently secured by 12 nominated validators, consisting of known and respected projects within the Ethereum ecosystem including the Maker Foundation, Giveth, Gnosis, Shapeshift, and Protofire. These validators are participating in a delegated Proof-of-Stake consensus where they provide STAKE to secure the chain, but do not currently have delegators and are not subject to a rotating validator set. This will change when public POSDAO (Proof of Stake Decentralized Autonomous Organization), a new consensus algorithm, gives all STAKE holders an equal opportunity to participate and benefit from the consensus process.
The xDai chain has seen rapid adoption from projects throughout the Ethereum ecosystem as recent high gas fees and congestion have made it difficult to transact on Ethereum. As a compatible L2 solution, developers can quickly deploy their infrastructure to xDai with minimal changes. While some projects have migrated completely, others have chosen a hybrid approach, moving some resource-intensive operations to xDai while keeping others on Ethereum.
The result is an interoperable infrastructure where xDai extends and augments the Ethereum operating space with a low-cost, stable transactional environment.
With Eth2 on the horizon, xDai has plans to continue providing scalability during the multi-year transition. Once realized, xDai will be prepared to be integrated into the Eth2 infrastructure. STAKE will continue to have a valuable role as a governance token with plans to incorporate transactional sequencing capabilities and more.

7. How is the applying collateral type currently used?
STAKE token supports Proof-of-Stake consensus, secures the payment layer, prevents malicious activities, and allows block producers to receive their staking incentives. It will also provide stake-weighted governance voting privileges for holders. It’s not implemented in everyday user transactions.
Users can also participate in staking on the Ethereum mainnet through the EasyStaking application. This serves to limit supply and provides emissions for those who lock STAKE into EasyStaking. It also incentivizes STAKE liquidity providers on Uniswap.
As of 2020-12-03T21:00:00Z, 1.298M STAKE with a value of over 13M in USD are staked in the Easy Staking protocol on Ethereum.
