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.

Firo (FIRO), formerly known as Zcoin, is a cryptocurrency that focuses on being private digital cash. It created the Lelantus privacy protocol which allows users to burn their coins and redeem them later for brand new ones that do not have any transaction history.

Prior to Lelantus, it was also the first cryptocurrency to code and launch a practical implementation of the Zerocoin protocol which became one of the most prevalent privacy protocols in use, prior to it being replaced by Sigma and then Lelantus after cryptographic flaws were discovered in the Zerocoin protocol in 2019.

ARK is a cryptocurrency- and blockchain- based development platform allowing anyone to create their own fully customizable and interoperable blockchain. Reducing the industries need for Smart Contracts by using custom transactions, logic and multiple programming languages. ARK was founded in mid 2016, running a Toekn Exchange Campain(TEC) later that year which raised $800K in bitcoin and other exchanged cryptos. Sound financial planning has allowed the team to become a well-funded entity since its inception. On March 21, 2017, the ARK Public Network went live, hosting the native ARK crypto asset. The ARK business entity formed shortly after, called ARK ECOSYSTEM SCIC. The business entity is commonly referred to as 'ARK.io' which is part of the teams branding as well as the teams website.

The ARK Ecosystem consists of an open-source blockchain technology stack authored in TypeScript programming language. ARK’s public network acts as a live implementation of ARK technology, node operators acting as delegates on the network, standalone blockchains running on ARK technology with independent node operators, business entities that develop products powered by ARK as well as assist in maintaining the code base, an enterprise division driving adoption as well as a community of users, developers and service providers.

The ARK Public Network supports special transaction types such as multi-payment, multisignature, many various registration transactions, and IPFS hash transactions. ARK’s Launcher product, allows fully customizable interoperable blockchain creation using a graphical user interface. This plug and play creation method allows developers to fully utilize ARK’s consensus model, technology stack, product line and custom transactions.

AdEx is a cutting-edge web3 marketing platform utilizing blockchain and programmatic advertising to elevate digital advertising. Through AdEx, Web3 advertisers can access an untapped market of potential crypto users.

Originating in 2017 as a decentralized ad exchange, AdEx has evolved into a full advertising protocol, boasting 20,000+ registered users and processing billions of micropayments on the blockchain. Currently, AdEx serves as a Demand-Side Platform, allowing advertisers to buy traffic through SSPs, conduct real-time bidding, and leverage programmatic technology. Moreover, AdEx maintains direct partnerships with premium publishers, encompassing all interactions between publishers, advertisers, and end users.

ADX, the native token of AdEx, serves as the platform's native utility token, playing a pivotal role in rewards, governance, payment, and staking. It incentivizes validator uptime, ensuring seamless advertising campaigns. The more tokens staked, the more robust the validator network becomes. ADX token holders can stake their tokens to receive generous rewards and participate in governance decisions. Moreover, advertisers leverage ADX for campaign payments, enjoying reduced fees compared to other payment options.

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).

Peercoin, also known as PPC or Peer-to-Peer Coin, was created by Sunny King and his team and launched in August 2012. It is the first blockchain to implement Proof-of-Stake consensus.

The primary inspiration behind the creation of Peercoin was to address a number of perceived shortcomings of Bitcoin, including energy efficiency, security and sustainability, decentralization and long-term viability.

Essentially it was designed as an enhanced replacement for Bitcoin. As such, it was originally forked from Bitcoin and uses the same UTXO style blockchain. However, Peercoin's code was modified to introduce Proof-of-Stake as its primary consensus protocol. The next section explains how this makes for a better blockchain.

Given that Peercoin uses most of the same code, it can easily port new features from Bitcoin and utilize any of the supporting infrastructure, including tech advancements like Taproot or Lightning Network. Peercoin is the only Proof-of-Stake blockchain that uses modern Bitcoin code, making it the perfect drop-in replacement.

Peercoin also has a dedicated community, is actively developed, fairly distributed, has low barriers of participation, can do everything that Bitcoin does, minus the 13 TWh of energy usage, and it's not a scam.
