The XinFin Hybrid blockchain network has shown tremendous growth since its launch in 2019. In the last 18 months, the XinFin Network Mainnet has added 19,411,041 blocks and added more than 120 Masternodes and Backup Nodes to support the smooth functioning of the network.

The XinFin Network has brought its community members a range of benefits such as smart contract support, near-zero gas fees, rapid transaction speed of fewer than two seconds, and also a reduction in energy consumption by 99% as compared to popular PoW networks.

Growing Demand for XDC
As the demand for XinFin Network grows and we onboard more community members, the usage of the XDC — the native coin of XinFin Network — is also seeing high demand and usage.

Since the launch, many industry players including exchanges, wallet providers, and custodians have partnered with us to integrate the XDC ecosystem or build applications on it. Other platforms such as Blockdegree, TradeFinex, and MyContract also progressed significantly and boosted the utility of the XDC.

On the other hand, there has been a recent spike in Ethereum gas fees, forcing exchanges to increase their gas fees for XDCE (ERC20 token). To help community members pay lower fees, these exchanges have also switched from XDCE to XDC. This shift has caused a high surge in the usage of XDC.

Burning XDCE Tokens
With XDC gaining more popularity among community members as compared to XDCE tokens, the XinFin community has decided to reduce the supply of XDCE tokens.

Hence, the network will burn 5 billion XDCE tokens taking the total supply of XDCE from 15 billion to 10 billion tokens. The community also plans to further reduce the supply of the XDCE tokens in the near future.

Users must, however, note that the swap between XDCE and XDC will be available only on Alphaex.net Exchange so that they may enjoy the utilities of the Ethereum network as well.

The XinFin team is also working on the automatic swap for XDCE and XDC.

People who are still confused with XDC and XDCE please watch the video:

We Are Open to Feedback
We believe that we can deliver the best of the XinFin network and the XDCE and XDC tokens to our users only when we know what our community members need. This is why we welcome feedback from our community members with open arms and work on them to make the network ready for the digitized future.

I’m going to briefly remind the readers about XDPoS before diving into the problem slashing aims to solve. I will then explain the slashing mechanism with XDPoS proposed slashing followed by a discussion of other slashing mechanisms from Ethereum Casper.

XinFin XDPoS Consensus Background
At the heart of XinFin, XDPoS that enables it to be an EVM-compatible and scalable public blockchain. This means that every Ethereum smart contract can be run on XinFin XDPoS with almost instant transaction confirmation. XDPoS relies on the architecture of 108 masternodes.

In order to become a masternode candidate, a token-holder must deposit at least 10 million XDC to a smart contract. masternode candidate is shown on a decentralized governance application called XinFin Master-Node App.

Masternodes are selected to create blocks in a round-robin fashion. A maximum of 900 blocks are created within an epoch and there is a block created every two seconds. Masternodes are also responsible for verifying and signing blocks in order to finalize the blocks. And all the masternode on the network are KYC enable masternode.

To strengthen system security, XinFin XDPoS also proposes double validation and randomization techniques. In double validation, when a masternode creates a block, this block must be verified by another masternode. The verifier is randomly selected among the remaining set of masternodes.

Decentralize Network instability and performance problem
So, what is the problem here? Remember that XinFin XDPoS is a public blockchain that allows anyone to freely join and leave the network. Now let’s consider a situation where the network has some underperforming masternodes. By underperforming, I mean the masternode does not sign/verify any blocks during the entire epoch. Some reasons for this might be that the masternode does not have the correct XinFin XDPoS software or the masternode crashes due to the lack of e-maintenance and operation by the masternode owner.

Underperforming masternodes can dramatically decrease the performance of the whole network and cause network instability. In XDPoS's current implementation, when a masternode fails to create a block on his turn, the whole network has to wait for 10 seconds of time-out before the next masternode in the round-robin takes its turn to create the next block. This means the whole network wastes m*10 seconds (m is the number of turns the underperforming masternode is selected within an epoch to produce blocks).

To make the problem worse, if ¼ (or 27 masternodes) of the 108 masternodes are underperforming, the total wasted time is 27 * 6 * 10 = 2220 seconds! It’s longer than the duration of an epoch. That being said, if these 27 masternodes are not eliminated out of the network, the performance will be decreased by more than 50%! There is actually a worst-case in which more than ¼ of the masternodes are underperforming. In this case, no finality can be reached since there are not ¾ of the masternodes signing off blocks. This means all masternodes are just wasting resources but completing nothing.

Slashing mechanism
The objective of the slashing mechanism is not to blame the underperforming masternodes but to mitigate the aforementioned issue to keep the system stable and performing. The slashing mechanism is as follows:

If a masternode does not sign any block during an entire epoch, the masternode will be slashed from the masternode for the next 4 epochs.

If more than one masternode is underperforming, the masternodes list for next epoch are chosen as follows:

If a masternode was considered as underperforming within 4 previous epochs, it is considered as ‘kicked-out’ and does not have the right to create blocks. Therefore, the number of masternodes responsible for creating blocks in this epoch might be less than 108. However, the active masternodes will not have to wait 10 seconds for underperforming masternodes’ blocks.

Once kicked out of the masternode list, the underperforming masternode can still verify and sign off blocks. This mechanism is used for the underperforming masternode to notify others about its liveness. However, the underperforming masternode does not receive rewards for verifying and signing off blocks after being slashed out.

This slashing mechanism has two properties:
Accountability: an underperforming masternode is always detected if it is silent within an entire epoch. XDPoS consensus has a smart contract called block signer. Block signer stores all block signatures produced by masternodes. The laziness of a masternode is easily accounted for by reading the number of signatures it has sent to the block signer smart contract during the epoch.

Liveness: If a previously slashed masternode becomes live again after 4 epochs of slashing, This property is guaranteed by allowing the demoted masternode to verify and sign off blocks, which is a signal demonstrating its liveness, as previously described.

Discussion
Slashing has been considered in Ethereum Casper FFG designed by Vitalik Buterin to move Ethereum consensus from Proof-of-Work-based to Proof-of-Stake-based. The objective of Casper slashing is to prevent Ethereum from the nothing-at-stake problem — in which Casper validators would choose to validate and finalize all forks. Attackers can take advantage of the nothing-at-stake problem to double spend. Casper slashing states that if two forks can be both finalized (a fork in Casper is considered as finalized if ? Casper validators validate the fork), there will be at least? Casper validators trying to validate both forks. These validators then lose their entire deposit for violating the consensus rule stating that one validator has to attest to only one fork.

Casper slashing tries to prohibit intentional bad behavior from malicious validators that violate the consensus rule. This is why slashing is very strong as it is used to discourage validators from committing any malicious behavior. TomoChain’s slashing is quite different in its philosophy. Underperforming masternodes do not intend to attack the network and the reasons for not verifying any block during an entire epoch might be, for example, an electrical problem or a server crashing. Burning the staked tokens of underperforming masternodes creates fear among participants, thus discouraging people from participating in the system. There is no reason to take all deposited tokens from an underperforming masternode just because its electricity source turns off for 30 minutes.

Step by step guide to deploy the smart contract on XinFin Testnet (Apothem) through XinFin Remix and XinPay.

Stage 1: Setup the Environment
You can find the XinFin remix at remix.xinfin.network. After this, you need to select the environment according to your contract.


After selecting the environment according to your contract you need to create a new file and name it.
Then you just need to paste your contract in the new file which you have created and select the compiler version as per your contract.


And then compile your contract.
Stage 2: Add XinPay in Chrome
After compiling your contract, you need to deploy it.
You would need to download XinPay in order to further deploy your contract.
Afterwhich, you can simply XinPay as an extension in your Google Chrome browser.


Once you accept all the terms and conditions, enter a strong password and remember your password as every time you would need to feed in the password in order to access XinPay.
After that, you will see a seed with which you can access your wallet. Make sure you take a proper backup of your Keystore as XinFin network is decentralized.
Post this, you would need to select XinFin Apothem network where you can get the test token from Faucet.


Stage 3: Deploy the contract
After getting the test token on XinPay, you can deploy the token from XinFin remix and submit the required transaction.


Post the deployment of the contract you can check the tx hash on the XinPay. This means you have deployed your contract successfully and you can check it on XinFin Scan.


Stage 4: Interact with contract
You can also interact with your smart contract on XinFin remix.

The new interface of XinFin Web Wallet running on XDPoS blockchain

The website of the web wallet is completely redesigned inside and out! View the web wallet link at https://xinfin.network/#webWallet

There is a great deal of discussion in the crypto community about the necessity of providing a great user experience if XinFin wants to see widespread adoption of XDPoS blockchain. At XinFin, we are focused on getting the best ideas out of the feedback and discussions and then implementing them, as simply and intuitively as possible, for our users.

In XinFin Web Wallet, we have brought you pretty color schemes, cute buttons, and friendly fonts but at the end of the day, what matters most for XinFin is the “great USER experience”.

XinFin believes in a simple interface that comes coupled with customer support and on-demand education. While we have great respect for the experienced users, we welcome the new users with open arms.

XinFin has a ‘no intrusion’ policy. XinFin doesn’t store any data related to users. There is no tracking, no emails, no ads, and no demographics. XinFin will never monetize in a way that interferes with the user experience. Security matters most for us.

In the world of crypto, interface updates are more than beautification. Interface updates are a process of arriving together as a community, at what will work best for all the current and future users of XDPoS blockchains. Better interfaces are all about discovering the most universally intuitive way of interacting with decentralized financial and governance structures so that their promise of zero barriers to entry can be fully realized. We contribute to that goal by always striving to make our product more secure and more accessible!

From the beginning, we wanted to create a platform that is compatible with all kinds of devices, be it desktop, tablet or mobile. The uncluttered, inviting interface works on any screen, allowing you to access your wallet instantly or, if you are a first-time user of XinFin Web Wallet, creating a new one.

We created our designs keeping in mind both kind of users?—?the experienced users and beginners. While experts should be easy-to-find what they need easily and quickly, novices should feel welcomed and helped when visiting our interface.

Intuitive and Convenient

For example, it’s easy to tell which methods to access XinFin Web Wallet are most secure. For now, we recommend a keystore file, private key. For your security, we do NOT recommend accessing with a mnemonic phrase.

We will soon be supporting hardware wallets like Ledger, KeepKey, Secalot, Trezor, BitBox, and Metamask. Our developers are working round the clock to get all these hardware wallets onboard.

Once you access the wallet, you can perform all the tasks at one place, from checking your balance to interacting with contracts, without ever having to re-login. Unlock once and use all the features until you log out!

Wallet balances are loaded automatically, without the need for third-party extensions. Not only that, XinFin now features notifications! No need to wonder about the status of your transaction?—?you will find this information updated in the notifications section, the small bell icon!

Developers can easily deploy smart contract and interact with a contract on XinFin network.

User can send tokens offline. If you are using XinFin Original Web Wallet (XOW) offline and locally, it is not possible to send transactions directly from the offline computer. To send or broadcast a transaction, an internet connection is required. To do this, you should use a second computer that is connected to the internet. This has the advantage of keeping your private key on a separate offline device that won’t be afflicted by malware or hackers.

Under the Hood
When developing XinFin Web Wallet, we did not just focus on the front end, because we would not be satisfied with a cosmetic change. We wanted to provide our users with a robust backend that can live up to the evolving future of the XinFin (XDPoS) ecosystem. And, a web wallet that supports a feature which allows users to store XDC and XDCE under one address for easy handling of private keys.

So we invite all community members to support for future enhancement of XinFin Web Wallet. Check the XinFin Web Wallet here and enhance the features and errors at https://github.com/XinFinOrg/Wallet

*XDC wallet is a free, client-side interface helping users interact with the XDPoS blockchain. XinFin is an easy-to-use, open-source platform that allows companies to seamlessly generate/integrate wallets onto its blockchain.

XDC Wallet will never manage accounts with sensitive information such as passwords, private keys, or email addresses. In order to ensure the security and privacy of your information, please ensure that no sensitive information is ever saved, stored, or transmitted while using XDC Wallet. Please note that we only have access to the information that is publicly available on the blockchain and we will never hold your assets.

Only users themselves can access and control their funds?—?this is the purpose of decentralized networks. Your funds are stored on the XDPoS blockchain itself, and we are simply an interface that allows you to easily interact with them. Passwords and private keys are in the users’ hands and are the users’ sole responsibility.

Online community support is available on below-mentioned Telegram and Slack channels.
