Learning the friendly way

In a string of new crypto assets available on Tap Global, Chainlink is one of the latest supported cryptocurrencies. The platform is renowned for being one of the biggest oracle platforms in the cryptosphere, making it possible for real-world data to communicate with blockchain applications.

Okay, so it's time to break down exactly what Chainlink is. You might be wondering why you should even care about this network when there are plenty of other decentralized projects out there. It all comes down to the fact that Chainlink aims to fix one obstacle that has prevented smart contracts from becoming more widespread in business and industry. Below we take a deeper look at what Chainlink is and what the platform has to offer. 

What is Chainlink (LINK)? 

Chainlink is a decentralized oracle platform designed to merge the blockchain world with the real world through data integration. The main aim of the platform is to allow smart contracts to capture real-world data, merging the two worlds.

Smart contracts are digital agreements that automatically execute when the agreed-upon conditions are met. Native to the blockchain industry, there is a significant gap between smart contracts capturing blockchain-specific data and external data like the weather, fiat currencies prices, sports scores, etc. 

Bitcoin, for instance, has a very small range of these input capabilities, while Ethereum can handle more due to its smart contract functionality. Chainlink is designed to provide a far greater range of input across the blockchain space through its network of oracles. 

These oracles are data providers that provide a bridge between smart contracts and external data sources. Each oracle is incentivized through a "reputation score" system to provide accurate data and rewarded accordingly with the platform's native token, LINK. 

Who Created Chainlink?

In 2014, Sergey Nazarov and Steve Ellis created a platform called SmartContract which allows smart contracts to come to life by connecting them to external data and widely accepted bank payments. This acted as the prelude to what would become Chainlink. 

The first version of Chainlink first emerged on the scene in mid-2017, founded by SmartContract. Three months later, the Chainlink whitepaper was launched by Navarov and Ellis. This was followed by a successful ICO which raised funds equating to $32 million, selling roughly 35% of the max supply of 1 billion LINK, funding the further development of the platform.

How does Chainlink works?

Alright, so now let's dig down into the nitty-gritty of how Chainlink works. Chainlink allows smart contracts to access external data. To do this, it provides an off-chain infrastructure that links smart contracts to all kinds of different data providers. This makes it much easier for smart contracts to get the information they need. The smart contract can then use this data in whatever way it needs to.

The first thing to understand is that smart contracts need external data in order to do their jobs. This makes sense, right? Your standard contract clearly specifies what happens when certain conditions are met. So what determines whether (and when) those conditions occur? Usually, it's some external force that a smart contract simply doesn't know about.

That means a blockchain-based smart contract can't fulfil its purpose without a way to get information from outside of the blockchain. So what do you do? You could have every individual app developer write their own oracles for each and every smart contract... or you can use a decentralized oracle network.

But what is the difference between centralized and decentralized oracles? Chainlink is great because it can be used to provide an 'outside view' to smart contracts... chainlink allows blockchain applications to securely access off-chain resources like traditional APIs, bank payments, and any other resource that's not currently on the blockchain.

Chainlink provides the security that developers need to run smart contracts without worrying about whether their favourite API is having problems. Chainlink also makes it possible for new data sources to be added to any smart contract which needs them.

Chainlink has three main processes in which it facilitates the communication of off-chain data with on-chain smart contracts. This is done through oracle selection, data reporting and result aggregation, as outlined below.

Oracle Selection

In this step, network users create a service-level agreement (SLA) outlining a set of desired data requirements. The platform then connects that SLA with relevant oracles providing that data. Parameters are then set and the user submits the SLA and deposits the required amount of LINK into what is called an Order-Matching contract, which is matched to the best bidding oracles. 

Data Reporting

Oracles then acquire the necessary real-world data outlined in the SLA from external sources, process the information and send it back to the smart contracts operating on the Chainlink network.

Result Aggregation

The results obtained by the data oracles are then tallied in an Aggregation contract, which assesses the validity of the data. It then allocates a score of the sum of all the data received to the user. This "track record" is used to verify an oracle's integrity, keeping a log of its completed requests, amount of LINK staked and average response time. 

Chainlink is also able to connect with oracles outside of its own blockchain network which is able to collect real-world data requested by the contracts. This process is managed by the Chainlink Core and Chainlink Adapter nodes. 

The network uses a Proof-of-Stake (Pos) consensus, relying on a staking protocol to ensure the network's security. 

How does Chainlink benefit me?

Chainlink is a decentralized oracle network that allows smart contracts to connect to external data sources. These can include APIs, internal systems, or other types of external data feeds. Chainlink's goal is to create a platform where developers aren't restricted from having their smart contracts interact with the outside world in any way they see fit.

You can start using Chainlink right away - no new platforms to learn, APIs to configure or other complex integrations.

chain link will never charge a fee for access to any of our oracle services. Our only source of revenue is the tokens you stake when retrieving outsourced data from your peers on the network.

What is LINK?

LINK is the native token to the Chainlink network and facilitates the communication of data. Considered to be an essential tool in merging blockchain technology with real-world applications, the token has gained wide popularity in the blockchain industry. Users use LINK to pay the nodes for their retrieving, verifying and sending of data. These prices are established by the node operator and based on the current market and demand for that data.

The node operators stake LINK in the Chainlink network to prove their commitment and good intentions. Nodes with bigger stakes take priority over nodes with smaller ones when matching them with SLAs.

LINK is an ERC20 token that powers the ChainLink Network. The LINK token serves three primary purposes:

1. A method to pay ChainLink Node operators for the retrieval of data from off-chain data feeds, like web APIs and other inputs
2. Incentivize the development of oracles that provide data to smart contracts.
3. A method of staking by clients who want access to our oracle network. 

The primary purpose of the LINK token is to secure the network by staking them. The user must stake a certain amount of LINK tokens to run a ChainLink node, which then acts as an oracle. In return, the user is paid for providing this service.

If you've been exploring the world of cryptocurrency beyond Bitcoin and Ethereum, you've probably heard of Sushi. No, not the Japanese dish – we're talking about a powerful player in the decentralised finance (DeFi) space that's been making waves since its dramatic entrance in 2020.

Sushi, or SushiSwap as the platform is called, burst onto the crypto scene with what many called a "vampire attack" on Uniswap, another popular decentralised exchange (DEX). This bold move involved attracting over a billion dollars of liquidity from its competitor in just a few days.

Today, SushiSwap stands as one of the leading decentralised exchanges in the crypto ecosystem, offering a suite of financial services that go well beyond simple token swapping. With its native SUSHI token, the platform has created an ecosystem that allows users to trade, earn, lend, borrow, and more – all without traditional financial intermediaries.

What makes Sushi truly stand out is how it's putting financial power back into the hands of regular users. By democratising access to sophisticated financial tools that were once only available to privileged institutions, Sushi is helping to create a more open, accessible financial system for everyone.

What is Sushi (SUSHI)?

At its core, Sushi is a DEX and DeFi protocol that allows users to trade cryptocurrencies directly with each other without any middlemen. Unlike centralised exchanges, there's no company controlling your funds or verifying your identity – it's just you, smart contracts, and the blockchain.

Think of SushiSwap as an online marketplace where instead of a company facilitating trades, everything runs on code. It's like if eBay operated without eBay the company – just buyers and sellers interacting through an automated system.

The relationship between SushiSwap and SUSHI is important to understand:

• SushiSwap is the platform – the actual decentralised exchange and suite of DeFi services
• SUSHI is the native token that powers the ecosystem – like owning a piece of the project

The Sushi ecosystem has evolved significantly since its launch, now offering a full menu of DeFi services:

• Token swapping (the basic exchange function)
• Liquidity providing (where users can earn fees)
• Yield farming (earning rewards by supporting the platform)
• Lending and borrowing
• Token launches
• NFT marketplace
• Cross-chain functionality (operating across multiple blockchains)

When compared to other DEXs like Uniswap and PancakeSwap, Sushi stands out for its community-first approach and wide range of features. While Uniswap pioneered the automated market maker model that Sushi uses, Sushi expanded on this foundation by adding more ways for users to participate and earn rewards. 

And while PancakeSwap operates primarily on the Binance Smart Chain, Sushi has expanded to multiple blockchains, including Ethereum, Polygon, Avalanche, and more.

The history of Sushi

Sushi's history reads like a crypto soap opera – complete with controversy, drama, and unexpected twists. Grab the popcorn.

It all began in August 2020 when an anonymous developer going by the name "Chef Nomi" created SushiSwap as a fork (essentially a copy with modifications) of Uniswap's code. But Chef Nomi didn't just launch a competitor; they executed what became known as a "vampire attack" – a strategy to drain liquidity from Uniswap by offering better incentives.

Users who provided liquidity to Uniswap could stake their LP (liquidity provider) tokens on SushiSwap to earn SUSHI rewards. Then, in a coordinated event called "The Migration," over $1 billion in crypto assets moved from Uniswap to SushiSwap virtually overnight. The crypto community was stunned by the aggressive yet innovative approach.

But the drama was just beginning. Shortly after the successful migration, Chef Nomi suddenly converted a large amount of SUSHI tokens (worth about $14 million at the time) into Ethereum and withdrew it. The community viewed this as an "exit scam," and the price of SUSHI plummeted.

In a surprising turn of events, Sam Bankman-Fried, then-CEO of FTX (a major crypto exchange at the time), stepped in to take control of the project. Days later, Chef Nomi returned all the funds and apologised to the community.

Control of the project was then transferred to a multi-signature wallet controlled by several trusted community members, transitioning SushiSwap to true community governance. Since then, the protocol has seen steady development and expansion, including:

• Launch of Kashi lending platform (March 2021)
• Introduction of BentoBox, a yield-generating vault (Q1 2021)
• Expansion to multiple blockchains beyond Ethereum
• Release of Miso launchpad for new tokens
• Development of Shoyu, an NFT marketplace

Despite its tumultuous beginnings, Sushi managed to establish itself as a serious contender in the DeFi space through continuous innovation and a strong community focus.

How does SushiSwap work?

SushiSwap operates on a model called an automated market maker (AMM), which is fundamentally different from traditional exchanges. Here's how it works in simple terms:

Instead of matching buyers with sellers (the way stock exchanges work), SushiSwap uses liquidity pools – essentially big pots of cryptocurrencies that users can trade against. Imagine a vending machine that's always ready to exchange one token for another, rather than waiting to find someone who wants the opposite side of your trade.

These pools are created and maintained by liquidity providers – regular users who deposit pairs of tokens (like ETH and USDT) into the pools. In return for providing this liquidity, they earn fees from trades that happen in their pool.

When you want to swap tokens on SushiSwap, here's what happens:

1. You select the tokens you want to exchange (for example, ETH for USDT)
2. Smart contracts calculate the exchange rate based on the ratio of tokens in the relevant liquidity pool
3. The more of one token you want, the more expensive it gets (this is called "slippage")
4. A small fee (0.3% of the trade) is taken and distributed to liquidity providers
5. The tokens are exchanged directly in your wallet

The beauty of this system is that it's all handled by smart contracts – self-executing code on the blockchain. There's no company processing your trade or holding your funds; it's all automated and trustless.

Of this 0.3% fee, 0.25% goes directly to liquidity providers in the pool, while the remaining 0.05% is converted to SUSHI tokens and distributed to SUSHI stakers. This creates a sustainable revenue model where active users earn from the platform's success.

Key features of the Sushi ecosystem

Sushi has evolved from a simple token exchange into a comprehensive DeFi ecosystem. Let's explore the main ingredients in Sushi's expanding menu:

SushiSwap DEX: The heart of the ecosystem is the decentralised exchange where users can swap virtually any ERC-20 token (and tokens on other supported blockchains). With competitive rates and deep liquidity across many trading pairs, it's the foundation of the Sushi experience.

Kashi: This lending and margin trading platform allows users to borrow assets against their crypto collateral. What makes Kashi unique is its isolated risk markets – meaning a problem in one lending market won't affect others, making it potentially safer than some competitors.

BentoBox: Think of this as a smart crypto savings account. BentoBox is a token vault that generates yield on deposited assets while they're waiting to be used in other Sushi products. It's like your money earning interest while sitting in your wallet, ready to use.

Onsen: This liquidity mining program incentivises users to provide liquidity for specific token pairs by offering additional SUSHI rewards. It's named after Japanese hot springs – places where people gather and relax, much like how Onsen gathers liquidity for the platform.

Miso: A launchpad for new tokens, Miso helps projects conduct token sales with various auction types. It's like Kickstarter for new crypto projects, helping them raise funds and distribute tokens fairly.

Shoyu: Sushi's NFT marketplace allows for the creation, buying, and selling of digital collectables. While newer than some competitors, it aims to offer lower fees and better integration with the rest of the Sushi ecosystem.

Cross-chain deployment: Unlike many DeFi protocols that only exist on Ethereum, Sushi has expanded to numerous blockchains including Polygon, Avalanche, Binance Smart Chain, Fantom, and more. This multi-chain approach helps users avoid Ethereum's sometimes high transaction fees while still accessing Sushi's services.

This diverse ecosystem makes Sushi a one-stop shop for many DeFi activities, allowing users to move seamlessly between trading, earning, lending, and more.

SUSHI tokenomics

The SUSHI token is the special sauce that brings the whole Sushi ecosystem together. Let's break down how it works:

Total supply: SUSHI has no maximum supply cap. New tokens are minted at a rate of 100 SUSHI per Ethereum block (roughly every 12 seconds), though this emission rate has been adjusted through governance votes over time.

Token utility: The SUSHI token serves several important functions:

• Governance: SUSHI holders can vote on proposals to change the protocol
• Fee sharing: When staked, SUSHI entitles holders to a portion of all trading fees
• Liquidity mining rewards: Users can earn SUSHI by providing liquidity
• Platform access: Some features may require SUSHI holdings or staking

Governance rights: Holding SUSHI means having a say in the future of the platform. Token holders can propose and vote on changes ranging from technical upgrades to treasury management and new feature development.

xSUSHI mechanism: When users stake their SUSHI tokens, they receive xSUSHI in return. This represents their share of the staking pool, which constantly grows as trading fees are added to it. When users unstake, they get their original SUSHI plus their portion of accumulated fees – making it a passive income opportunity.

Staking rewards: The current APY (Annual Percentage Yield) for staking SUSHI varies depending on platform volume and the number of stakers, but it has historically offered attractive returns compared to traditional finance.

Market performance: As with many cryptocurrencies, SUSHI has experienced significant price volatility since its launch. After reaching all-time highs during the 2021 bull market, the token has settled into a more stable trading range. 

The tokenomics of SUSHI are designed to align the interests of users, liquidity providers, and token holders – when the platform succeeds, SUSHI holders benefit through increased value and fee sharing.

How to buy and sell SUSHI

Conclusion

Sushi has come a long way from its controversial beginnings to establish itself as a cornerstone of the DeFi ecosystem. What started as a fork of Uniswap has evolved into a comprehensive financial platform that offers trading, earning, lending, and more – all without traditional financial intermediaries.

By addressing one of the biggest pain points in DeFi – high Ethereum gas fees – through multi-chain deployment, Sushi makes decentralised finance more accessible to everyday users.

As with any cryptocurrency project, Sushi faces challenges and competition, but its innovative features, passionate community, and continuous development make it a project worth watching in the years to come.

Wanting to stake ETH but don't have the full 32 ETH required? Enter Rocket Pool – the game-changing protocol that's making Ethereum staking accessible to everyone.

Founded in 2016 and launched on mainnet in October 2021, Rocket Pool breaks down the barriers to Ethereum staking by allowing anyone to participate with as little as 0.01 ETH. Or, if you want to run a node, you'll need 8 ETH (plus some RPL as collateral) instead of the standard 32 ETH.

In this guide, we break down everything you need to know about the protocol, including its two key tokens:

• RPL: The governance token that also serves as insurance for the protocol
• rETH: A liquid token that represents your staked ETH and automatically grows in value as rewards accumulate

By democratising access to staking, Rocket Pool stays true to Ethereum's vision of decentralisation while making it possible for anyone to earn rewards from securing the network, with no massive ETH holdings required!

How Rocket Pool works

Rocket Pool's design has three main components that work together to facilitate decentralised ETH staking: smart contracts, smart node network and minipools. 

The Smart Contracts Backbone

At the foundation of Rocket Pool lies a sophisticated set of smart contracts that govern all protocol operations. These contracts manage:

• Deposit pools where regular users stake their ETH
• The creation and management of minipools (validator nodes)
• The minting and burning of rETH tokens
• The staking and distribution of RPL rewards
• Protocol governance mechanisms

The smart contracts ensure that all operations happen in a trustless manner, removing the need for intermediaries and preserving the decentralised ethos of Ethereum. They incorporate various security measures, including extensive testing and multiple independent audits to safeguard user funds.

Key smart contracts include the Deposit Pool, Minipool Factory, and Token contracts. When users deposit ETH, the smart contracts either match them with node operators to create validators or mint rETH representing their stake and accumulated rewards.

Smart Node Network and Minipools explained

Rocket Pool's network consists of independent node operators running the Rocket Pool Smart Node software. This software interacts with the protocol's smart contracts and manages validator duties on the Ethereum network.

Node operators in Rocket Pool contribute 8 ETH (rather than the full 32 ETH required for solo staking), which is matched with 24 ETH from the protocol's deposit pool to form a standard 32 ETH validator. This validator unit is called a "minipool."

The process works as follows:

1. A node operator installs and configures the Smart Node software
2. They deposit 8 ETH and a minimum of 10% worth of ETH in RPL tokens as collateral
3. The protocol matches this with 24 ETH from regular stakers
4. A minipool (validator) is created and begins participating in Ethereum consensus
5. When the validator earns rewards, they are split proportionally between the node operator and the deposit pool

This system creates a symbiotic relationship between those who want to stake without running infrastructure (regular stakers) and those willing to operate nodes but don't have the full 32 ETH requirement (node operators).

The minipool design is particularly innovative because it allows for fractional validator ownership while maintaining security through RPL collateral requirements. If a node operator behaves maliciously or negligently, their RPL collateral can be slashed, protecting regular stakers from potential losses.

Understanding RPL and rETH

As mentioned earlier, Rocket Pool's ecosystem revolves around two main tokens, each serving specific functions within the protocol. 

What is RPL used for?

RPL (Rocket Pool Protocol Token) is the native utility and governance token of the Rocket Pool protocol, designed to align the interests of node operators with the long-term success of the protocol. Unlike rETH, which represents staked ETH, this ERC-20 token serves several specific functions:

1. Node operator collateral: Node operators must stake a minimum of 10% of their ETH value in RPL tokens as security against wrongdoing. This collateral can be slashed if the node operator behaves maliciously, protecting the protocol and its users.
2. Insurance mechanism: The RPL staked by node operators creates a protocol-wide insurance fund that helps secure user deposits and maintain trust in the system.
3. Additional rewards: Node operators can stake up to 150% of their ETH value in RPL to receive proportional RPL rewards, incentivising greater security deposits and alignment with protocol success.
4. Governance: RPL token holders have voting rights on protocol upgrades, parameter changes, and other governance decisions through the Rocket Pool DAO.

What is rETH and how does it work?

rETH is Rocket Pool's liquid staking token that represents staked ETH plus accumulated rewards. These automatically increase in value relative to ETH through a changing exchange rate rather than requiring separate reward claims.

How to stake ETH with Rocket Pool (step-by-step)

Staking ETH with Rocket Pool as a regular user (not a node operator) is straightforward and accessible to anyone with an Ethereum wallet. Here's a guide to getting started:

Option 1: Using the Rocket Pool dApp

1. Connect your wallet: Visit the Rocket Pool website and navigate to the staking interface. Connect your Ethereum wallet (MetaMask, WalletConnect, etc.).
2. Determine your stake amount: Decide how much ETH you want to stake (minimum 0.01 ETH).
3. Approve the transaction: After reviewing the details, confirm the transaction in your wallet. This will swap your ETH for rETH at the current exchange rate.
4. Receive rETH: Once the transaction is confirmed, you'll receive rETH in your wallet, representing your staked ETH plus future rewards.

Option 2: Using decentralised exchanges

1. Access a DEX: Open a decentralised exchange that supports rETH/ETH pairs (Uniswap, SushiSwap, Balancer, etc.).
2. Execute the swap: Trade your ETH for rETH through the exchange interface.
3. Store your rETH: Keep your rETH in your wallet or utilise it in compatible DeFi protocols.

Monitoring your stake

Once you hold rETH, your rewards accumulate automatically through the increasing exchange rate between rETH and ETH. To monitor your rewards:

1. Check the current rETH/ETH exchange rate on the Rocket Pool website or through blockchain explorers.
2. Calculate the difference between the current value of your rETH holdings and your initial investment.

Remember that you don't need to claim rewards separately - they're built into the increasing value of your rETH tokens. When you eventually want to unstake, you can simply swap your rETH back to ETH through the Rocket Pool interface or a decentralised exchange.

How to become a Rocket Pool node operator

For those with technical expertise and a desire to become more actively involved in Ethereum's consensus mechanism, becoming a Rocket Pool node operator offers an opportunity to run validators with reduced capital requirements while earning additional rewards.

Prerequisites:

• 8 ETH for each minipool (validator) you wish to create
• At least 10% of your ETH value in RPL tokens as collateral (for maximum rewards, up to 150%)
• A computer or server that meets the minimum requirements:
  
  • 4+ CPU cores
  • 8+ GB RAM
  • 100+ GB SSD storage
  • Stable internet connection
• Basic command line knowledge
• Understanding of Ethereum staking principles

Step-by-step process:

1. Set up your hardware and operating system: Either use a dedicated machine or a cloud service provider. Most node operators use Linux-based systems.
2. Install Ethereum clients: Set up an execution client (Geth, Nethermind, etc.) and a consensus client (Prysm, Lighthouse, etc.).
3. Install Rocket Pool Smart Node software: Follow the detailed instructions on the Rocket Pool documentation site to install the node software.
4. Configure your node: Set up network settings, client preferences, and MEV-boost options if desired.
5. Deposit ETH and RPL: Use the node software to deposit your 8 ETH and the required RPL collateral.
6. Create your minipool: Once your deposits are confirmed, create a minipool which will be matched with 24 ETH from the deposit pool.
7. Monitor and maintain your node: Keep your system updated, monitor performance, and participate in protocol governance if desired.

The future of Rocket Pool

As Ethereum continues to evolve, Rocket Pool is positioning itself for sustained growth and adaptation. In coming years, several key developments and trends will likely shape its trajectory.

Protocol upgrades:

The Rocket Pool development team has outlined an ambitious roadmap with several major upgrades:

• Saturn upgrade series: A comprehensive set of improvements focusing on scalability, capital efficiency, and user experience. The Saturn upgrade is a multi-phase initiative, with Saturn 0 completed and further phases underway.
• Distributed Validator Technology (DVT): Implementation of validator key distribution across multiple operators, enhancing security and reducing single points of failure.
• Greater MEV optimisation: Advanced strategies for maximising Maximal Extractable Value for stakers while maintaining ethical standards.
• Cross-chain expansion: Potential expansion to other proof-of-stake networks or layer-2 solutions that require validation services.

Scaling with Ethereum:

As Ethereum implements its scaling roadmap, Rocket Pool will adapt to support:

• Danksharding and proto-danksharding implementations
• Increasing validator requirements as Ethereum grows
• Adjustments to staking economics as Ethereum's monetary policy evolves
• Supporting specialised validation roles that might emerge in Ethereum's future

Market position and growth:

While Rocket Pool currently holds a smaller market share than some competitors, its emphasis on decentralisation potentially positions it well for sustainable growth. Here are key aspects worth keeping an eye on:

• Increasing regulatory scrutiny may favour more decentralised staking solutions
• Growing community awareness of centralisation risks could drive users toward Rocket Pool
• The protocol's conservative approach to security and upgrades builds long-term trust

Addressing the speed and cost concerns associated with the Ethereum platform and decentralized cryptocurrency exchanges, Loopring delivers a new layer to the DeFi space. Describing itself as “an open-source, audited, and non-custodial exchange protocol,” Loopring is bringing something new and innovative to the space.

Below we answer the burning questions surrounding the DeFi project, such as what is Loopring, how the Loopring protocol works, and what the LRC token is responsible for.

What is Loopring (LRC)?

Loopring is many things. Under the far-stretching umbrella, there is the company, Loopring Project Ltd, the decentralized exchange, Loopring Exchange, the Loopring Protocol, the Loopring Relayer (the backend that powers the protocol), the Loopring Wallet, and the token, LRC.

The layer two protocol is an open DeFi protocol that allows other exchanges to build on top of it. The protocol supports a number of crypto assets and implements zero-knowledge rollups (zkRollups) to address the slow speeds and high costs associated with decentralized exchanges on Ethereum. With zkRollups, Loopring seeks to enable faster settlements for traders by allowing key computations to be completed on other blockchains.

By reducing the number of transactions submitted to the Ethereum network, Loopring exchanges can increase the speed with near-instantaneous settlements and reduce costs for traders.

The Loopring Exchange aims to offer a hybrid platform combining the best features of centralized exchanges and decentralized exchanges, addressing issues like structural limitations and transparency. The platform combines centralized order matching with decentralized blockchain order settlement, using zero-knowledge proofs (ZKPs) for enhanced privacy, reduced costs, and high speeds.

LRC tokens were first made available to the public in August 2017 as part of an ICO. In December 2019, the Loopring protocol, built on the Ethereum blockchain, was officially launched. 

Who created Loopring?

Loopring was established by Daniel Wang, a software engineer based in Shanghai. Wang has an impressive resume of prior experience working at prominent companies like Google, medical device manufacturer Boston Scientific, and Chinese e-commerce giant, JD.com. While Wang has continued to serve as the CEO of Loopring Foundation.

In 2017, Loopring conducted an initial coin offering (ICO), successfully raising 120,000 ether valued at $45 million. However, due to the tightening regulatory environment surrounding ICOs in China, the company decided to return 80% of the funds raised from the public sale.

Despite this setback, the Loopring team allocated the remaining proceeds toward the development of their platform.

How does Loopring work?

When you perform a transaction directly on Ethereum (a layer one blockchain) the cost of the transaction depends on the amount of data it contains. Larger transactions, which have more data, require more computing power to process and therefore end up being more expensive. Layer two solutions, on the other hand, tackle this issue by executing transactions outside of layer one, resulting in lower costs and less congestion.

As a layer two solution, Loopring does this by utilizing a newer type of cryptography called zero-knowledge rollups, also known as zkRollups. In the term "zkRollups," the "zk" refers to "zero knowledge." Zero knowledge proof is a cryptographic technique that enables one party to prove the truth of a statement to another party without disclosing any information about that statement.

Rollups, on the other hand, batch transactions together and execute them outside of layer one. So after the transaction data is processed, it is posted back to layer one to reach a consensus. This batching process is what enables transactions on layer two to be more affordable.

The Loopring team responsible for the Loopring protocol is the same team that developed the Loopring Exchange, which was the first zkRollup-based exchange accessible to the public on the Ethereum network. This successful launch demonstrated the protocol's effectiveness and the underlying technology.

Loopring sets itself apart from other trading technologies in the decentralized finance (DeFi) space by utilizing an order book-based approach. While decentralized, trading on a Loopring-powered decentralized exchange (DEX) is more similar to trading on centralized exchanges, which primarily rely on order books, but without the security or custodial concerns. This is in contrast to most decentralized exchanges that heavily rely on user-generated liquidity through automated market maker (AMM) technology.

To illustrate its effectiveness, Loopring can handle up to 2,025 trades per second, which is approximately ten times faster than Ethereum can achieve on its own. On top of that it can also lower transaction fees and the overall transaction cost due to its effective use of layer two technology.

What is the LRC token?

The Loopring cryptocurrency, LRC, plays a crucial role in the operations of the protocol.

To operate a decentralized exchange on Loopring, a minimum of 250,000 LRC needs to be locked up. This allows the exchange operator to utilize on-chain data proofs. Alternatively, an operator can stake 1 million LRC to run an exchange without this feature.

LRC serves as an incentive for the proper utilization of the Loopring network. Exchange operators who deposit LRC may face confiscation of their deposits by the protocol if they operate exchanges poorly. These confiscated funds are then distributed to users who choose to lock up LRC.

Additionally, any user can stake LRC to earn a share of the trading fees paid to the protocol. Approximately 70% of the fees are distributed to users who stake LRC. Another 20% is allocated to the Loopring Decentralized Autonomous Organization (DAO), which allows a pool of funds to be used according to the discretion of Loopring users in the future.

Lastly, 10% of the fees are burned, meaning the total supply of LRC decreases over time, leading to potential upward pressure on its price. The maximum supply of LRC tokens is set at 1.375 billion.

How can I buy LRC tokens?

For those interested in accessing the Loopring (LRC) market, users have the option to buy or sell Loopring LRC tokens through the Tap app.

Livepeer is a decentralised video streaming network that aims to make video content more accessible and affordable for everyone. Launched in 2017, it was the first fully decentralised live video streaming network protocol, offering an alternative to traditional centralised streaming services like YouTube and Twitch.

The platform works by connecting video creators who need their content processed with computer operators who provide the computing power. This peer-to-peer approach can reduce streaming costs by up to 50-90% compared to traditional cloud providers while maintaining high quality and reliability.

TLDR

Decentralised video infrastructure: Livepeer is a decentralised network for limitless video computing, enabling AI processing and transcoding jobs to power the future of video.

Cost-effective streaming: Designed to make streaming more reliable while reducing costs, Livepeer acts as a decentralised marketplace for developers building applications that integrate live video and transcoding providers.

Ethereum-based protocol: Built on Ethereum, it aims to provide a blockchain-based alternative to centralised streaming services, giving developers freedom to innovate and creators independence from big platforms.

Native token (LPT): The Livepeer Token (LPT) is the protocol token of the Livepeer network, used for staking and network governance rather than direct payments.

What is Livepeer (LPT)?

Livepeer creates a global network where anyone can contribute computing power to help process video content. When someone wants to stream a video, instead of using expensive centralised servers, the content gets distributed across this network of independent computers.

The magic happens through video transcoding: the process of converting video files into different formats and quality levels so they can be watched on different devices and internet speeds. Traditional streaming services handle this with massive, expensive data centres. Livepeer does it through thousands of smaller computers around the world.

This approach benefits everyone involved. Content creators get cheaper streaming costs, computer operators earn money for contributing their resources, and viewers get the same high-quality experience they expect from streaming platforms.

The network is particularly valuable for developers building video applications, as they can tap into Livepeer's infrastructure without setting up their own expensive video processing systems.

Who created Livepeer?

Livepeer was founded in 2017 by Doug Petkanics and Eric Tang, both entrepreneurial software engineers who had been long-time collaborators before starting the project.

Doug Petkanics serves as CEO and brings over 10 years of experience as an entrepreneur and software developer. Before Livepeer, he was a co-founder and VP of Engineering at Wildcard and attended the University of Pennsylvania.

Eric Tang, who serves as CTO, co-founded Livepeer to utilise blockchain technology to reduce costs and increase efficiency in video streaming. The platform has grown significantly under their leadership, now featuring more than 70,000 GPUs that encode videos for large platforms.

The founding team recognised that video streaming was becoming increasingly expensive and centralised, with a few big companies controlling most of the infrastructure. They set out to democratise video streaming by creating a decentralised alternative that could compete on both cost and performance.

How does Livepeer work?

Video transcoding network

The core of Livepeer is its video transcoding network. When someone uploads a video, it needs to be converted into multiple formats and quality levels (like 1080p, 720p, 480p) so it can be watched on different devices and internet connections.

Instead of using one large data centre, Livepeer distributes this work across thousands of computers worldwide. These computers, called "orchestrators," compete to provide the best service at the lowest cost.

Staking and network security

Computer operators who want to join the network must stake LPT tokens as a form of security deposit. This ensures they'll do good work; if they provide poor service or try to cheat, they can lose their staked tokens.

Users can also "delegate" their LPT tokens to trusted orchestrators, earning a share of the rewards while helping secure the network without running their own hardware.

Economic incentives

The network creates a marketplace where video processing jobs go to the orchestrators offering the best combination of price, quality, and reliability. This competition naturally drives down costs while maintaining high standards.

Payments for video processing are typically made in ETH or other cryptocurrencies, while LPT tokens are used for staking and governance rather than direct transactions.

What Is LPT?

LPT is a staking token in the Livepeer Network that helps reduce costs for video broadcasters. Unlike many crypto tokens, LPT isn't primarily used for payments, it also provides:

• Network security: Orchestrators must stake LPT tokens to participate in the network, ensuring they provide reliable service.
• Governance rights: LPT holders can vote on important network decisions and protocol upgrades.
• Delegation rewards: Token holders can delegate their LPT to orchestrators and earn a portion of the fees those orchestrators collect.
• Work token: LPT represents the right to perform work on the network and earn fees from video processing jobs.

The token follows an inflationary model where new LPT is created to reward network participants, but this inflation is balanced by the value created through network usage and growth.

How can I buy and sell LPT?

If you're interested in exploring LPT, you can do so easily through the Tap app. The app supports buying, selling, trading, and storing LPT tokens, allowing verified users to manage LPT alongside other digital assets.

When considering LPT investment, it's important to understand that the token's value is closely tied to the network's adoption and usage. As more developers and content creators use Livepeer's infrastructure, the demand for LPT staking and the overall network value should increase accordingly.

Harvest Finance is a decentralised yield farming protocol that automates the process of earning maximum returns on crypto investments. Launched in 2020 on the Ethereum blockchain, it functions as a yield aggregator that automatically moves users' funds between different DeFi protocols to capture the highest available yields. It now operates on additional blockchains such as Binance Smart Chain and Polygon.

The platform was designed to solve one of the biggest challenges in DeFi yield farming: the time and expertise needed to constantly monitor and switch between different protocols to maximise returns. Instead of users having to do this manually, Harvest Finance does it automatically, making yield farming accessible to everyone.

TLDR

Automated yield farming: Harvest Finance is a DeFi protocol that automatically farms the highest yields available from various DeFi protocols and pools, optimising returns using advanced farming techniques.

Yield aggregator: Harvest Finance serves as a yield aggregator where assets are deposited into strategic vaults to maximise their yield.

Vault system: Users deposit their crypto assets into specialised vaults, receiving fTokens in return that represent their share of the vault and accumulated rewards.

Native token (FARM): FARM is the governance token that allows holders to vote on protocol parameters and share in farming revenue. FARM token holders can vote on proposals for the operational treasury and may receive a fee from Harvest operations

What is Harvest Finance (FARM)?

Harvest Finance simplifies the complex world of yield farming by creating an automated system that does the hard work for users. When you deposit your crypto into a Harvest vault, the protocol automatically deploys your funds to various DeFi platforms that offer the best returns at any given time.

Think of it like having a professional fund manager for your crypto, but instead of a human making decisions, smart contracts automatically move your money to wherever it can earn the most. The protocol automatically farms the highest yield by moving funds between farming pools on your behalf, eliminating the need for users to constantly research and switch between different platforms.

The platform supports various types of assets including stablecoins, popular cryptocurrencies, and liquidity pool tokens. When you deposit assets, you receive fTokens (like fUSDC for USDC deposits) that represent your share of the vault and track your earnings over time.

Harvest Finance's goal is to make yield farming more accessible by automating the process and optimising the potential returns using the latest farming techniques, bringing sophisticated DeFi strategies to everyday users.

Who created Harvest Finance?

The founders of Harvest Finance remain anonymous, which was common for many DeFi projects launched in 2020. The team is completely anonymous, though the project succeeded in attracting a relatively sizable community and has been involved in the community by doling out grants.

Despite the anonymous nature of the founding team, Harvest Finance has built a strong reputation in the DeFi community through its transparent operations and community involvement. The token was distributed via fair launch with no token sales to investors, demonstrating the team's commitment to decentralised principles.

The project launched during the height of the 2020 DeFi summer when yield farming became extremely popular, and the anonymous team capitalised on the growing demand for automated yield optimisation tools.

How does Harvest Finance work?

Vault Strategy System

The platform operates through a system of specialised vaults, each designed for different types of assets and risk profiles. When you deposit crypto into a vault, you receive fTokens that represent your share of that vault's total holdings.

The magic happens behind the scenes, where the protocol's strategies automatically deploy your funds to various DeFi protocols like Compound, Curve, Uniswap, and others based on where they can earn the highest yields. The system constantly monitors yield opportunities and automatically rebalances to maximise returns.

Automated Yield Optimisation

Harvest Finance's protocol design automatically farms the highest available yields and distributes the profits to users in the pool. This means users don't need to understand the complexities of different DeFi protocols or spend time managing their positions.

The protocol uses sophisticated algorithms to determine the best allocation of funds across different yield farming opportunities, taking into account factors like APY rates, smart contract risks, and gas costs for rebalancing.

Profit Sharing Model

When the automated strategies generate profits, these are shared among all users in the vault proportional to their deposits. A portion of the profits is also distributed to FARM token holders who stake their tokens in profit-sharing pools, creating an additional incentive layer for the community.

What is FARM?

FARM serves as the governance and profit-sharing token of the Harvest Finance ecosystem:

• Governance Rights: Holders can vote on protocol parameters and propose or veto the introduction of new Vaults, giving the community control over the platform's direction.
• Profit Sharing: FARM, when deposited in Profit Sharing pools, becomes a means of participating in farming revenue, allowing token holders to earn a share of the protocol's success.
• Protocol Incentives: Harvest at launch required a native crypto so as to be able to incentivise yield farmers, and allow Harvest to stake other platforms and collect rewards in return.
• Community Participation: The token creates alignment between users and the protocol's long-term success, as both benefit from higher yields and more efficient farming strategies.

FARM operates as an ERC-20 token on Ethereum, making it compatible with the broader DeFi ecosystem and easily tradeable on decentralised exchanges. While FARM is originally an ERC-20 token, it also exists on other blockchain platforms such as Polygon and Binance Smart Chain, expanding to multiple blockchains to offer yield farming opportunities across different ecosystems

How can I buy and sell FARM?

For those looking to participate in automated yield farming, FARM tokens are readily available through the Tap app. You can purchase, sell, and store FARM tokens securely while managing them alongside your broader crypto portfolio.
