## What Is xDai (STAKE)?

xDai is a cryptocurrency that is pegged to the US dollar. The xDai chain is a stable payment blockchain that is designed for fast and inexpensive transactions. STAKE is secured by [proof-of-stake](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake) consensus. xDai was founded on Oct. 1, 2018.

STAKE is a multi-chain staking token that is designed to secure the payment layer. Staking allows validators and delegators to provide transaction consensus and receive staking incentives for block production. It is only required for consensus providers, not everyday on-chain transactions.

xDai was created by the POA Network, an open-source public side-chain of Ethereum founded in April 2017. It offers a framework for smart contracts which provides developers with an easy and effective way to code on Ethereum, while also leveraging the POA Network capabilities.


### Who Are the Founders of xDai? 

The founder of xDai (STAKE) is Igor Barinov. He is also the founder of the POA Network, an R&D company whose mission is to ensure that the Ethereum protocol is cheap, fast, secure and scalable. Barinov has developed several projects in the past, such as BlockScout and TokenBridge.

Igor Barinov is also a co-founder of Block Notary, Forcera OU and is a blockchain consultant at Acronis.


#### What Makes xDai Unique? 

xDai is a derivative of the DAI cryptocurrency, which is a stablecoin whose price is pegged to the US Dollar. The cost to perform a transaction with xDAI is $0.000021 USD. Such a transaction takes up to five seconds. 

xDai can be received or sent to another user through the usage of the Dex Wallet mobile application, or the Poketto xDai mobile wallet.

#### How Many xDai (STAKE) Coins Are There in Circulation? 

The xDai chain uses the [ERC20](https://coinmarketcap.com/currencies/erc20/)-to-native TokenBridge functionality to provide stable, fast and inexpensive transactions.

xDai’s (STAKE) circulating supply is at 4,058,408 STAKE as of February 2021, with a maximum supply of 8,537,500 STAKE.


### How Is the xDai Network Secured?

xDai provides virtual public utility for users. The xDai token is used to secure the xDai chain by validators and delegators. Users can participate in chain consensus and stake their xDai to secure the chain and receive rewards. 

Two bridges connect the xDai Stable Chain to the Ethereum mainnet that supports seamless two-way asset transfer between the chains. The tokens are acquired on the mainnet and then bridged to the xDai sidechain through the usage of the DAI-xDai bridge for transaction tokens; the OmniBridge is used for cross-chain transfers. 

It is important to note that xDai runs on the public POSDAO consensus and delegated proof-of-stake and anyone with enough STAKE to run a node can become a validator. Delegators help determine the validator bet by placing STAKE on candidates that they want to see become validators.

Ampleforth is an Ethereum-based cryptocurrency with an algorithmically adjusted circulating supply. It is designed to be the base money of the new decentralized economy, by providing an asset that cannot be diluted by supply inflation and remains decoupled to the price action of other cryptocurrencies—and Bitcoin (BTC) in particular.

With Ampleforth, token holders own a fixed fraction of the total AMPL circulating supply, rather than a fixed number of tokens. When the protocol detects that the price of AMPL is too high, it increases the circulating supply, whereas the supply is decreased if the price is too low.

This change is propagated to all Ampleforth wallets, which have their wallet balance adjusted proportionally. Irrespective of this change, AMPL holders will still retain the same percentage of the token supply.

This automatic supply adjustment process is known as a “rebase” and occurs once each day, with a positive rebase if the price goes above $1.06, and a negative rebase if it is below $0.96. The overall goal of the system is to create incentives that drive the market price of AMPL back to ~$1.

Ren (REN) is an open protocol built to provide interoperability and liquidity between different blockchain platforms.

To learn more about this project, check out our deep dive of Ren.

Formerly known as Republic Protocol, Ren launched RenVM, its virtual machine mainnet, in May 2020, having completed a $34 million initial coin offering (ICO) in 2018.

The protocol’s native token, REN, functions as a bond for those running nodes which power RenVM, known as Darknodes.

Ren aims to expand the interoperability, and hence accessibility, of decentralized finance (DeFi) by removing hurdles involved in liquidity between blockchains.

Balancer is an automated market maker (AMM) that was developed on the Ethereum blockchain and launched in March 2020. It was able to raise a $3M seed round by Placeholder and Accomplice. Balancer protocol functions as a self-balancing weighted portfolio, price sensor and liquidity provider. It allows users to earn profits through its recently introduced token ($BAL) by contributing to customizable liquidity pools.

To learn more about this project, check out our deep dive of Balancer(https://coinmarketcap.com/alexandria/article/what-is-balancer.

The protocol operates a few types of pools:

Private pools give the owner governance over the pool, and make the person the sole contributor of liquidity to the pool. Also, all the parameters are mutable by the owner.

Shared pools are for those who want to become liquidity providers (LPs). The LPs are rewarded with the Balancer Pool Tokens (BPTs).

Smart pools are similar to private pools but are controlled by a smart contract. They also reward using BPTs and allow anyone to contribute liquidity to the pool.

Balancer

Band Protocol is a cross-chain data oracle platform that is able to take real-world data and supply it to on-chain applications, while also connecting APIs to smart-contracts to facilitate the exchange of information between on-chain and off-chain data sources.

By supplying reputable, verifiable real-world data to blockchains, Band Protocol unlocks a range of new use cases for developers to explore — since they can now use any type of real-world data as part of their decentralized application (DApp) logic, including sports, weather, random numbers, price feed data and more.

Band Protocol initially launched as an ERC-20 project on the Ethereum blockchain in September 2019, but transitioned to the Cosmos network in June 2020 with the release of Band Protocol 2.0. The new protocol is built on BandChain using the Cosmos SDK. Oracle nodes on BandChain not only relay data but are also involved in block production/validation, giving them a dual role.

BAND is the native token of the Band Protocol ecosystem and is used as collateral by validators involved in fulfilling data requests, as well as the main medium of exchange on BandChain — being used to paying for private data.

MIR is the governance token of Mirror Protocol, a synthetic assets protocol built by Terraform Labs (TFL) on the Terra blockchain.

Mirror Protocol is decentralized from day 1, with the on-chain treasury and code changes governed by holders of the MIR token. TFL has no intention of keeping or selling MIR tokens, and there are no admin keys or special access privileges granted. The intent for this is to be a completely decentralized, community-driven project.

Mirrored assets are blockchain tokens that behave like "mirror" versions of real-world assets by reflecting the exchange prices on-chain. They give traders the price exposure to real assets while enabling fractional ownership, open access and censorship resistance as any other cryptocurrency. Unlike traditional tokens which serve to represent a real, underlying asset, mAssets are purely synthetic and only capture the price movement of the corresponding asset.

Mirrored assets provide the following advantages:

Global Accessibility: In most markets outside of Europe & North America, access to foreign equities and forex markets is highly limited. Crypto allows global accessibility without entry barriers.

Fractional Orders: In traditional finance, to execute a fractional order, multiple fractional orders are bundled together to execute a unitary transaction. The process of gathering all the orders into one requires additional waiting time. By utilizing the blockchain, orders volume is simply represented as a number on the blockchain, so there is no need for the intermediary bundling process.

Nearly-Instantaneous Order Execution: Oftentimes due to the lack of liquidity (price-time-priority order book algorithm), orders can take up to a day to fully execute. Given the fact that Mirror relies on liquidity provided by each individual asset pool, orders can be executed as fast as the blocktime of the network (~ 6 seconds).

Hifi (formerly Mainframe) is a Lending Protocol that allows anyone to borrow against their crypto. Hifi uses a bond-like instrument, representing an on-chain obligation that settles on a specific future date. Buying and selling the tokenized debt enables fixed-rate, fixed term lending and borrowing — something much needed in decentralized finance today. It is anticipated that a ticker symbol change will occur alongside future iterations on the Hifi Lending Protocol.

Mainframe Token (MFT) is the native utility token that is used for:

Governance votes

Staking to ensure the safety of the protocol

Rewarding contributors to the ecosystem

What can you do with the Hifi Lending Protocol:

Borrow:  Lock collateral in a vault to mint fixed-rate, fixed-term debt tokens.  These debt tokens can be swapped for instant liquidity allowing users to leverage long, yield farm, or pursue other strategic trades without selling their collateral tokens.

Lend:  Buy fixed-rate, fixed-term debt tokens for a discount.  When the term expires they can be redeemed for face value, earning lenders a predictable return on their investment.

Provide Liquidity:  Earn trading fees by providing liquidity between debt tokens and stablecoins on an Automated Market Maker (AMM).
