Groestlcoin is a proof of work cryptocurrency created in 2014. Designed for everyday use, Groestlcoin features an average block time of one minute, as opposed to Bitcoin's ten. As a consequence, it has a maximum total supply that will cap out at 105 million coins, as opposed to the 21 million for Bitcoin. The main idea of creating Groestlcoin was to establish an electronic payment model that was purely based on mathematical proof. It uses the proof of work system (POW) to facilitate secure online money transactions. This is a system that is independent of influence from centralized authorities.

### How does it work?

Groestlcoin is mined using the Groestl algorithm. Groestl was chosen as one of the five finalists of the NIST hash function competition. It uses the same S-box as AES in a custom construction. The cryptocurrency operates as open source software on a peer-to-peer model (transactions take place directly between the payer and payee). This means that no trusted intermediary such a bank or PayPal is required to verify the details of the sender and receiver. Rather, the transactions are verified by nodes (the network of computers/users spread globally) and recorded in an open ledger.

### What does it aim to solve?

With a shorter block period than Bitcoin, Groestlcoin aims to be more functional for everyday payments. Merchants don’t need to wait 10 minutes to confirm whether or not they have received their payment. The reduction in hashrate intensity also gave Groestlcoin an opportunity to be mined by individuals with less computing power. However, companies and teams have created ASICs for Groestlcoin, albeit at a higher cost than creating ASICs for Bitcoin. Rather than just a simple fork, Groestlcoin also works to adopt developments and additions inspired from discussions surrounding the Bitcoin network, and was actually one of the first adopters to several key features such as Segregated Witness (SegWit) and the Lightning Network.

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).

BitShares Blockchain is a decentralized “Blockchain as Organization” (BaO); an industrial-grade decentralized open source platform built to run high-performance financial technology operations. It represents the first decentralized autonomous decentralized community that enables its core utility token (BTS) holders to decide the Blockchain future direction in order to develop and maintain a wide range of decentralized financial technology products, features and functions. BitShares Blockchain is a Blockchain that permanently records financial technology operations between different Blockchain accounts and facilitates a wide range of access controls across BitShares Blockchain user financial means.

BitShares Blockchain is a technology that supports the digital generation entrepreneurs, investors, and developers with a common interest in building and participating in free market solutions by leveraging the power of globally decentralized consensus and decision making. Consensus technology has the power to do for economics what the internet did for information. It can harness the combined power of all humanity to coordinate the discovery and aggregation of real-time knowledge, previously unobtainable. This knowledge can be used to more effectively coordinate the allocation of resources toward their most productive and valuable use.

BitShares looks to extend the innovation of the Blockchain to all industries that rely upon the internet to provide their services. Whether its banking, stock exchanges, lotteries, voting, music, auctions or many others, a digital public ledger allows for the creation of distributed autonomous companies (or BaO) that provide better quality services at a fraction of the cost incurred by their more traditional, centralized counterparts. The advent of (BaO) ushers in a new paradigm in organizational structure in which companies can run without any human management and under the control of an incorruptible set of business rules. These rules are encoded in publicly auditable open source software distributed across the computers of the companies’ shareholders, who effortlessly secure the company from arbitrary control. BitShares does for business what bitcoin did for money by utilizing distributed consensus technology to create companies that are inherently global, transparent, trustworthy, efficient and most importantly profitable.

BitShares has went through many changes and has done its best to stay on top of Blockchain technology. BitShares is using Consensus as the mechanism by which organized people decide upon unitary rational action. While not considered technology in the traditional since, consensus “technology” is the basis of democratic governance and the coordination of free market activity first coined by Adam Smith as the “Invisible Hand.” The process of consensus decision-making allows for all participants to consent upon a resolution of action even if not the favored course of action for each individual participant. Bitcoin was the first system to integrate a fully decentralized consensus method with the modern technology of the internet and peer-to-peer networks in order to more efficiently facilitate the transfer of value through electronic communication. The proof-of-work structure that secures and maintains the Bitcoin network is one manner of organizing individuals who do not necessarily trust one another to act in the best interest of all participants of the network. The BitShares ecosystem employs Delegated Proof of Stake in order to find efficient solutions to distributed consensus decision making.

Strike is a DeFi lending protocol that allows users to earn interest on their cryptocurrencies by depositing them into one of several markets supported by the platform.

When a user deposits tokens to a Strike market, they receive sTokens in return. These sTokens represent the individual’s stake in the pool and can be used to redeem the underlying cryptocurrency initially deposited into the pool at any time. For example, by depositing ETH into a pool, you will receive sETH in return. Over time, the exchange rate of these sTokens to the underlying asset increases, which means you can redeem them for more of the underlying asset than you initially put in — this is how the interest is distributed.

On the flip side, borrowers can take a secured loan from any Strike pool by depositing collateral. The maximum loan-to-value (LTV) ratio varies based on the collateral asset, but currently ranges from 50 to 80%. The interest rate paid varies by borrowed asset and borrowers can face automatic liquidation if their collateral falls below a specific maintenance threshold.
