## What Is Bifrost (BFC)?

Bifrost is a multichain middleware platform that enables developers to create Decentralized Applications (DApps) on top of multiple protocols. Not restrained to a single blockchain, Bifrost creates a new environment where developers can combine the best protocols to develop substantially more scalable and flexible DApps.

With Bifrost, developers can write smart contracts for multiple blockchain protocols in an unified environment. They simply select the target blockchain for each part of the code, then Bifrost will transpile, compile, and deploy the code into the target blockchains at once. Developers can also easily operate their DApps and even switch the target blockchain as new and better protocols become available. 


Bifrost has multiple components that allow for a seamless connection among all blockchains:

- Recipe: A language application that defines the programming language of Bifrost and generates smart contract codes with guaranteed code-level flexibility.
- Linker: A system that connects the user and Bifrost components, ensuring the seamless operation on top of multiple blockchains.
- Builder: An Integrated Development Environment (IDE) that offers a customized environment to use the comprehensive suite of features of Bifrost.
- Gourmet: An automated testing environment for Bifrost service and smart contract development, updating with the latest technologies for blockchain.
- Scan: A dashboard that provides you with a full view of the internal process of Bifrost and shows your blockchain interconnectivity in diagram.

## What Makes Bifrost Unique?
- Flexibility: To maximize the potential of the blockchain technology, a superior flexibility that allows users to select and combine blockchains is needed. Bifrost focuses on this flexibility, enabling developers to extract the most from blockchains.
- Scalability: Bifrost operates with multiple blockchains without any additional abstraction layers, so you can use the features of each blockchain directly. Its flexibility enables you to apply different blockchains best suited to your needs.
- Interoperability: The value of interoperable blockchain service grows as the blockchain industry grows. On Bifrost, you can build services with countless possibilities for combinations and interoperability, from the start.
- Full Dev Suite: Bifrost provides a full suite of features to develop and operate your product, including an IDE, monitoring function, and client service such as wallets.

## What are its use cases?

BFC (Bifrost token) is the currency of Bifrost’s multichain ecosystem. Developers pay BFC for using the multichain middleware to develop and operate their DApps, minimizing the cost of gas fees when using multiple blockchain protocols than when using one blockchain. More specifically, they will be required to stake a certain amount of BFC and the fees will be deducted from it. Once the staked amount reaches below a threshold level, they will be asked to purchase BFC to meet the threshold again. 
The first DApp to be powered by Bifrost is the multichain DeFi platform, BiFi. Using Bifrost’s multichain technology, BiFi can connect directly to multiple blockchains like Bitcoin, Tron, and Klaytn, thereby expanding the DeFi ecosystem currently limited to Ethereum. BiFi will have its own token, BIFI, which will be used for governance and also to pay the fees for using multichain DeFi services. As BiFi's multichain is powered by Bifrost, BiFi will periodically purchase BFC with BIFI and pay it to Bifrost.
The development of Bifrost continues, with more features tailored to DeFi DApp development and serving multichain DeFi developers in the future. When DApp sectors like DID, NFT, and Gaming grow, Bifrost will become the preeminent multichain platform from day one. Future DApp developers will be able to customize the combination of blockchains to build more scalable, interoperable, and flexible DApps, and use BFC to power them.

## How Many BFC Coins Are There in Circulation?

A total 4 billion BFC tokens were issued. 256 million BFC tokens are currently in circulation since our Uniswap listing on December 2nd, 2020 at 11 AM UTC. Two rounds of private sales were held in 2018 and 2019, and public sale was held in June 2020. 

Of the total supply of BFC tokens, 20% is allocated for each of the following: Bifrost Reserve, Ecosystem, and Team. 4% is distributed to investors and the last 10.4% is used for marketing. BFC tokens for the Reserve, Ecosystem, Team, and Advisors will be distributed over a 5-year span, with a 1 year lock-up and a 4-year vesting period. 

## Who Are the Founders of Bifrost?

Founded on March 14, 2016, PiLab, a research-oriented software provider, was started by two professors to develop blockchain applications to solve social issues and business problems. In the process, they saw the potential and limitations of blockchain technologies. There were many protocols, all with their own strengths and weaknesses, and no way to combine them. So they created Bifrost, a technology platform that allows developers to easily build on multiple blockchains that truly enables multichain technologies. 

As the CEO and co-founder of Bifrost, Dohyun Pak has developed and managed complex derivative products for financial institutions in the U.S. and Korea for over a decade.

REQ is listed on Coinbase, Binance, crypto.com, KuCoin and many other exchanges.

The REQ token powers the Request Network open-source protocol via a few mechanisms: anti-spam; governance; staking; discounts; independency.

The Request (REQ) utility token, launched in 2017, ensures the performance and stability of the Request Network. The Request Network itself is an Ethereum-based decentralized payment system where anyone can request a payment and receive money through secure means. It removes the requirement for third parties in order to provide a cheaper, more secure payment solution that works with all global currencies.

The original whitepaper is available here.

When a user creates a request for payment, they define to which address the payment needs to be allocated and what the amount is. The user can also define the terms and conditions of the payment, upgrading a simple request into an invoice. Once this is completed, the user can share their request to be paid by their counterparty.

Every step is documented and stored on the Request Network, allowing everyone involved to easily keep track of all the invoices and payments for accounting purposes.

Request is also integrated with legislation across the world to remain compliant with the trade laws of each individual country.

ABBC is a blockchain platform that enables secure payment transactions, helping to facilitate retail adoption of cryptocurrencies and make shopping online with digital assets a safer, more enjoyable experience for end-users.

The platform offers three main products: a multi-platform wallet capable of supporting Bitcoin (BTC) and Ethereum (ETH), in addition to a variety of other native cryptocurrencies and ERC-20 tokens; an online shopping application that can be used to shop at over 50 online retailers with cryptocurrencies; and a cryptocurrency exchange platform that offers secure trading and low transaction fees.

The ABBC Coin was created to give holders the ability to govern the development of the ABBC platform by delegating voting power to chosen block producers (BPs) — who are then able to vote on governance proposals. These governance proposals can be on a range of topics but might include launching strategic partnerships, implementing new features or expanding ABBC's services to new regions. Beyond this, ABBC Coins were created as a reward system for online shoppers and can be staked for regular rewards.

ABBC is currently based on the EOSIO blockchain, which enables it to achieve up to 5,000 transactions per second (TPS) while remaining environmentally friendly due to its energy-efficient delegated proof-of-stake (DPoS) consensus mechanism.

ABBC Coin was initially known as Alibabacoin but changed its name in March 2019 following a dispute with Chinese multinational e-commerce giant Alibaba.

Orchid (OXT) is the native token of Orchid, a cryptocurrency-powered virtual private network (VPN).

Launched in December 2019, Orchid describes itself as the world’s first incentivized, peer-to-peer privacy network.

Its aim is to overcome internet freedom limitations by using cryptocurrency payments to allow anyone to purchase bandwidth from any participating provider. This is done using so-called probabilistic nanopayments, which occur using OXT, an ERC-20 standard token on Ethereum.

Regular payments to providers occur off-chain, allowing Orchid to avoid problems with congestion and gas fees on the Ethereum network.

The service is pay-per-use, meaning that users only have to contribute funds when they actually connect, instead of paying monthly or annual fees.

Fei protocol is a DeFi native algorithmic stablecoin. The aim of Fei is to propose a technological solution in a sweet spot between rigid overcollateralized decentralized stablecoin and centralised custodial stablecoins.

Fei Protocol runs on two crypto assets: FEI stablecoin and TRIBE governance token.

FEI is aimed to be a more capital efficient and fully decentralized stablecoin. The protocol uses the value it controls to maintain liquid secondary markets and earn yield for the protocol.

The project was founded in December 2020 and immediately attracted significant interest in the crypto community. It resulted in $19 million VC investment in early March 2021. Among the names that have entered this project are Andreessen Horowitz (a16z), Coinbase Ventures, Nascent and Framework Ventures.

There were some issues with the peg in the original mechanism, but through a series of governance upgrades the protocol recovered in the months following launch.

Fei v2 intends to be a major upgrade for the system and will launch in late 2021. It features 1:1 redeemability for FEI against protocol reserves, TRIBE buybacks and backstop, and algorithmic protocol controlled value management.

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.
