Every decentralized network rewards users by simply distributing tokens, however, DAFI is not just yet another staking protocol. Because the issue with conventional staking platforms is that when adoption is low it creates an excess supply of tokens and devalues the economy.

 DAFI introduces the first alternative since Satoshi, to use network rewards for building a decentralized economy. Instead of directly issuing tokens for staking & liquidity – DAFI ties synthetics to each network’s adoption. This means that the token’s released & network demand is proportional. By linking these two factors, it attracts longer-term users to be incentivized longer, supporting adoption.

Instead of distributing a token directly, the DAFI protocol enables networks to create a synthetic token in a reduced quantity. It enables networks to reward users, based on their adoption. Every decentralized network can soon create synthetic dTokens tied to the adoption of their protocol.

SUPER STAKING:

The idea of inflation rate on Ethereum networks and the dilemma following it has been flawed. For most networks there is continuous issuance, with a temporarily fixed, yet fork-moveable inflation rate, such that the total amount of token is uncertain. A major flaw is calculation of the value of a token if the eventual supply is not fixed or even mildly deterministic. On the other hand, if the inflation rate is kept low, users are not properly incentivized and there is a greater risk of security. 

To solve this and more, DAFI along with our team at Blockapex Labs worked to develop a protocol that can be used to create a secondary shadow token backed by the staked base tokens.

DAFI is the native-token of the protocol and is used for staking. By supporting the network, users are rewarded for their staking collateral by accumulating synthetics that further expand in quantity, only as demand rises. This will be the first implementation of an adoption-tied reward model. As more networks adopt DAFI to reward their users, the governance model will be gradually implemented.

For example,

• If you Super Stake $Matic you will receive dMatic. 
• The dTokens multiply when the market has a high demand for $Matic tokens, protecting the network. 
• This combats hyperinflation.

With DAFI protocol networks can create  synthetic dTokens which are pegged to network adoption & demand. As demand rises in the network, the synthetic reward increases in quantity itself. As demand declines, it reduces it's own quantity to enhance scarcity & prevent supply-shocks. 

DAFI AND dDAFI:

The idea behind ‘Super Staking’ is converting user staked DAFI into dDAFI which is a fungible token and no matter who stakes, they will all receive the dDAFI, which is more than just plain token rewards. dDAFI will grow alongside the network, multiplying user rewards and providing higher incentives without inflation of tokens.

THE JOURNEY OF DAFI AND Blockapex Labs:

Blockapex Labs shook hands with DAFI for the Super Staking web app, which was launched with its Dashboard, Super Staking and Superpool feature on 30^th June 2021. Team at Blockapex Labs followed a modular approach to develop an impressive Dapp. You can check it out here: stake.dafiprotocol.io

The network had staked 20 million before the end of 3^rd day of launch. At the moment of writing this, there are 88.82 million locked in Ethereum and Binance combined. DAFI aims at building their own bridge before the Polygon launch but we can wait on it.

There are a few more features of Market and Swap within the Dapp to cut off third party dependencies. 

HOW SUPER STAKING WORKS:

DASHBOARD:

Stake.dafiprotocol.io opens you to the dashboard view of the app. Making sure your wallet is connected to Binance/Ethereum mainnet you can preview cards containing network and user information:

• Total DAFI Staked: 

It is the total amount of DAFI staked on all chains. Of which, currently, Binance and Ethereum are working.

• Your DAFI Staked:

This is the representation for the amount staked by a user from a certain account in their wallet.

• Fees Collected:

Fees Collection goes simple, each time someone decides to exit, a withdrawal fee is applied to convert dDAFI rewards into DAFI. This is currently set at 25%, the dDAFI fees are sent back to the rewards pool and later redistributed to active-users in the system. Over time, you will accumulate a portion of other users' fees.

• Rewards:

All native DAFI tokens are collateralised and an intermediary is given which is a dToken.

The dToken expands and decreases in proportion to network demand. The dToken can be burned for the underlying native token. It creates a flexible approach that measures the health (demand) of the network before issuance.

In stages of low demand people can also burn tokens however the reward in native tokens is much less which incentives people to HODL long term.

• Potential:

This is the quantity your dToken rewards would multiply to at maximum network demand, ie. Potential APY.

Below the top 5 info cards is a graphical representation of change in user rewards as the network grows. For optimization factors, the graph retrieves data from the sub graph every 2 hours and updates accordingly. 

Adjacent to the graph are vertical bars showing the value preserved in each chain. Ethereum, with its high user count, is clearly winning at it.

Next we have a Transaction Store to view all relevant information from a transaction and then a ‘Top 5 Users’ table to show the top contributors of the network.

STAKE:

What actually happens in Superstaking is that you would be able to stake your DAFI on the platform by connecting your wallet and earn rewards in dDAFI which is tied to the demand of the network, the higher the demand the higher the quantity and vice-versa. Also there is an added 25% withdrawal fee, so if someone decides to exit the system. They need to pay this fee and this fee would be redistributed to the other users who are currently staking on the networks. So basically this would help long term users to incentive much better as the project matures and grows over the time.

Using the navigation drawer on the left, a user can navigate within the app. On clicking ‘Stake’, a user can make use of top 3 functionalities of the Super Staking app:

• SUPER STAKE:
  Staking a minimum of 2500 DAFI.

• UNSTAKE:

Un staking their DAFI + 75% of their earned dDAFI rewards converted back to DAFI.

WITHDRAW:

Users can claim their rewards from the Withdraw section of the Stake tab. An amount is deducted to be redistributed in the network every time a claim takes place. The withdrawal fee is currently set at 25%. So when some unstakes or claim their reward. A withdrawal fee is deducted from their rewards at first and then it gets added to the rewards pool and from there it gets redistributed to the active stakers in the system.

SUPERPOOL:

In the last of the working functionalities, we have Superpool, a graphical representation of staked DAFI preserved in each chain. (For now, Binance is working).

Important network informations of DAFI locked, APY and potential APY are dynamically displayed to user:

MARKET: 

Market is the feature developed to keep track of the $DAFI network growth along with social info. Your all-in-one hub for protocol & token info.

Metrics for determining demand factor for super staking are set to be price and TVL. Price is already implemented. So with an increase in price, there will be an increase towards potential APY hence an increase in dDAFI rewards. TVL will also be implemented.

Currently 88.73m $DAFI tokens have been locked in for super staking, that is more than 30% of the circulating supplyExploding head.

The $ETH pool has a potential of 26.11% APY. 

$BSC pool currently has a potential of 20.43%.

Blockapex Labs came up with this very cool idea of previewing official DAFI tweets straight from their twitter @DafiProtocol.

They also came up with this idea of showing total DAFI users on each chain with a simplistic Pie chart. Super Staking’s Market is one of the minimalistic ones in the DeFi world.

SWAP:

DAFI is developing their own bridge for swapping their token on various chains. This is planned to be launched in mid September. Stay tuned!

CONCLUSION:

We are all about making blockchain technology better. We believe Super Staking allows blockchains to have a higher security without hurting the ecosystem. DAFI Super Staking is playing a great part in finding an optimal staking solution for the inflation rates and we are glad to be a part of it all! Be part of the open economy of the future.

Polkalokr serves as an escrow platform, where they lock the tokens until the product is delivered and verified. Polkalokr fosters innovative project development over credible chains, initially started out with Ethereum. Their products are there to help build trust in Web3 projects, especially in the Defi space by introducing solutions which will pave the way for decentralized governance adoption. 

Polkalokr Bridgr

Blockchain technology has illustrated a great promise of utility over several fields including “Internet of Things” , finance, governance, identity management, web decentralization and asset-tracking but we have yet to see a single chain successfully achieve all with the ability to scale  and not get stuck into the blockchain trilema. Interoperability allows different chains to collaborate and enable the users to benefit out of other chains in case of facing any blockers on a single chain . LKR Bridgr was created to safely migrate the LKR tokens to other networks.  The vision was to make a cross-chain bridge which would support token migration on prominent chains and not limit the solution to just ethereum and Binance. Since Ethereum has a high gas price users would rather have their funds migrated to chains with low gas price as a standard for instance Binance and Ethereum L2 solution - Polygon chain

The bridgr is interoperable between three famous chains - Ethereum, Binance and Polygon. Polkalokr also opened an opportunity for businesses having their tokens on the above-mentioned chains, they can deploy bridge contracts for their respective tokens using the bridge service enabled by polkalokr platform. 

Architectural Diagram

Bridge User Flow

1. Connect Wallet:

Decentralized applications expect the user to connect their account to the Dapp via wallet extension or wallet application . 

Once the wallet is connected, the account which is currently activated will have its address in the From box. Considering EVM compatible chains have the same account address, users can opt for the source address to migrate the funds on the same account address on other supported EVM compatible networks.

2. Migration from primary chain to the secondary chain: 

After connecting your wallet, now you have to select the chain from the dropdown to which you want to migrate your LKR tokens.  

• You will be asked to give approval of the tokens to be first transferred to the bridge contract of the native chain.

• After the amount of token is entered, a fee is calculated which will be charged to migrate the funds from one chain to another, gas fee will be paid by the projects on every migration.

• Before confirming the transaction a modal is prompted which entails a calculated amount of fees expected - ‘incurred fee’ on the other chain for claiming the funds in the form of tokens that are being transferred . 

• The incurred fees will be deducted from the amount of the tokens getting migrated. 

• The bridgr will directly transfer the funds to your account address on the selected chain without making the user worry about paying the fees on the secondary chain in native token. 

• Once the tokens are transferred to the bridge contract, it takes 40-60sec for the migration to be successful on the secondary chain but the time will be impacted incase of congested network.

3. Migration check through explorer:

 Check the migration hashes using explorers, you can check the ins and outs of funds bia account address. 

Conclusion

Web3 space is all about creating a safe and decentralized space for users to engage and provide easy access to services in a decentralized capacity by ensuring security. Polkalokr enabled  businesses and individuals to escape from the hassle of creating the bridge from scratch and benefit from the service being made available for all. Polkalokr will soon launch bridge as a service, which will open doors for many projects to safely deploy their bridge contracts for their respective tokens and benefit from the inherent security provided by the platform. After the launch of bridge as a service, more evm compatible chains support will be added eventually.

Blockapex Lab's Task: To build an ethereum app, Numio.

Introduction

Numio is based on the idea to simplify the adoption of blockchain and they work on identity-based blockchain technology. They believe that a person should securely own his digital assets and online identity. To keep things simple they have made the design of the apps basic and handles all the complicated technicalities in the background. When it comes to blockchain, the complexity of its concepts makes it harder to understand for a common person. Blockchain-based products and applications are considered complicated that could make them less user-friendly. Although blockchain technology is taking over the world with all its perks, convenience in gaining its benefits is also important.

What makes Numio different

The basic design of Numio apps is what makes the user experience better. One can store money and make payments via the Numio app in an efficient and easy manner. The Numio app supports a public key cryptography-based two-factor authentication system that not only increases the security but also enables the users to rapidly recover their accounts through their biometrics using zkProofs. Moreover, the identity of a user can be quickly verified by their biometrics.

Numio App

Numio app is one of the applications of Numio. It is a mobile wallet app that allows transactions of cryptocurrencies. An amazing feature of Numio is that it is a non-custodial wallet app, which means it allows users to have full custody of their assets. Users can also securely transfer their personal data to third parties and can be safe from any kind of theft. Quick verification of identities by means of biometric technology is also one of its features.

Problems Solved By Numio App

Since the intention was to make the utility of Blockchain mainstream without making it complex, there were a bunch of problems that needed to be solved and limitations that needed to be reduced. Our team at Blockapex Labs devised the possible solutions to these problems, refined the ideas, and brought these ideas to life. Here are some exceptional features of the app that we helped them design:

1. Supports Multiple Tokens

The first problem it solves is that it enables users to handle 4 types of cryptocurrencies (1 currency and 3 tokens). This way the app enables users to convert tokens into other tokens or currencies. It means that the user does not have to handle different wallets for different currencies instead they are handled in the background.

2. Transactions Made Easy

Another problem was lengthy wallet addresses. The user had to copy a wallet address whenever he had to make a transaction. Numio app encounters this by collecting the contacts from the user’s device who are already using the Numio app and displaying the list at the time of transaction. One would only have to select a name from the list to perform transactions. The wallet address is a requirement if the recipient is not a Numio user. If the person is a Numio user but not in the contacts list, the transaction can easily be made by using his Numio ID.

3. Decentralizes the Wallet

The next issue it solves is the centralization of the wallet apps. It means that the authorities used to have access and can store the private keys and data of the users. Numio provides decentralization which means that only the users are in full control and authorities have no access to their private keys or data.

4. Batching Transactions

Transactions can be canceled or, at times, prolonged due to miners demanding high gas fees. This is because most wallets carry transactions on Layer 1 which uses ETH and carrying out every transaction differently could be very costly. To counter this, Numio involves ZkRollups, where bundles of numerous transactions are compressed in one single transaction and sent on Layer 2 Scaling using multiple tokens. This helps in reducing fees per user transfer and is faster as well. Currently, the token being used is $PHNX but further on multiple tokens can be used as well.

5. Provides a Two-factor Authentication System

Security breach is a problem with centralization because of data storage in one place. Every time that happens the authorities have to ask the users to change their passwords in order to keep their wallets secure. Numio solves this problem by means of identity verification procedures known as KYC which includes biometric verification and QR code scanning. This 2FA system also enables users to switch between other products such as Numio Vault.

How It Functions:

1. Create Your Numio Account

For ease of use, the user can now make their Numio I.D through a Google account. Furthermore, the Numio app allows identity confirmation and verification through blockchain and biometrics. The app holds proof of verification that cannot be edited, this includes a function for facial recognition. You can also sign up for other exchanges by using your verified identity without making another account for them.

Google I.D Logins & Its Benefits

Google logins help users to directly get a Numio I.D by using the information on their Google account. Plus, users now have the option to keep their private key safe using an encryption key in the Numio app, Google helps the user to store their account’s secret decryption key in the GDrive else it was impossible without Google’s account.

Facial Recognition

This feature helps during the KYC process as it becomes the most reliable security where the user will scan their face to verify the document is legit and belongs to the same user. Moreover, this becomes a unique identifier for the Numio I.D and whenever the user tries to recover their account, they must verify themselves using this facial recognition.

The Registration Process

The registration follows 4 steps:

• Generating Standard Wallet
  In this, a normal wallet is created where the user is provided with his private and public key.
• Creating Numio Wallet
  The new Numio-ZkSync wallet is created for the user in this step which allows them to do batch transactions.
• Identity Creation
  The KYCs of the user are now added to the database i.e, facial recognition and biometrics.
• Registration Complete
  The registration is now complete and the Numio app is ready to use.

2. Perform Transactions

• The view which appears after signing up displays the total balance in your wallet app. The user sees the option to “Request” or “Pay” the tokens. He can also view transaction history.
  The new Numio user will also see a pop-up to backup the recovery key to his Google account.

• The user has options to use features like deposit, withdraw, purchase, import wallet, and make internal transfers.

• The app lets you scan the QR code for verification and signing into other third-party applications.

• Users can also change the tokens and see the equivalent of each in USD.

• To withdraw, the user needs to fill in the information required as shown and click “Withdraw”.

• Similarly, to make an internal transfer, after filling in the details, the user has to click “Confirm” to confirm the transaction.

• To purchase, the user can select “Purchase Crypto” and enter the amount he needs to purchase.

• In the Identity tab at the bottom, the user can verify his identity.

Current Standings:

The app is being integrated with other exchange apps such as Numio Vault. Numio supports WBTC, PHNX, USDC.
