Why Nervos Works: Layer 1 for Security and Decentralization

Since Nervos was founded in 2018, we have been working to create a blockchain platform that has the capabilities to forge a new path in Web 3.0.
This means not only being a successful and viable platform today, but also having the foundations to be future-proof in a fast-paced space.

The construction of Nervos is what makes it a platform with such potential.
A solid and secure Layer 1, with a Layer 2 environment that is flexible and scalable, is aimed at being inherently multi-chain.

To better understand Nervos’ goals, it is good to get a grasp of its foundational layer – The Common Knowledge Base (CKB).
CKB, while also the token ticker, is Nervos’ Layer 1 and provides, among other things, the highest degree of blockchain security and potential for decentralization.

More than this, the construction of CKB allows for a flexible and scalable Layer 2 to work independently and independently on top of it, making it an ideal playground for blockchain dApp developers.

In this article, we will be diving into Why Nervos Works: Layer 1

Store of Assets

At its core, CKB is a Store of Assets public permissionless blockchain; the same description can also be given to Bitcoin.
 However, CKB is different from Bitcoin, but does borrow a lot of its good bits.

First of all, CKB, like Bitcoin, is Proof-of-Work, and while there has been a lot of debate around the environmental impact of PoW coins, much of the arguments are straw man fallacies.
PoW was selected for Nervos’ Layer 1 because only PoW meets all the demands for a truly decentralized system.

Proof-of-Stake systems permission the consensus process, allowing the largest validators to consolidate their status over time and entrench themselves in positions of power on the network.
PoW, on the other hand, offers far more open access to competition, and no one is likely to maintain a leading edge in technology and operation forever.

A Layered Approach

PoW helps with decentralization, but also with security, this is because CKB is purposefully tasked with security for the network.
This layer doesn’t do any computation, but focuses solely on validation of transactions, keeping the blockchain honest.

CKB is referred to as being a “cryptographic court” because it serves as a regulator for off-chain transactions.
This frees up Layer 2 to focus on scalability while providing optimal decentralization.

This layered architecture of Nervos, as highlighted above, shows how the two layers work independently and independently of each other.
It also shows how we have settled issues of scalability and fluidity while maintaining security and decentralization due to the make up of CKB.

This layered approach means Nervos has the ability to store assets, like Bitcoin, but it also has smart contract capabilities, like Ethereum.
However, CKB has been designed to be a state verification and storage system instead of a computation platform.
The Layer 1 blockchain verifies and stores states, while the computation-intensive state generation happens on Layer 2.

The Common Knowledge Base

The name for our Layer 1 is not arbitrarily chosen. Common knowledge is information that is accepted by a group of people, but not only does this group have common knowledge,
they also know that other participants in the group have the same knowledge – and this is important for Nervos and Blockchain.

The idea of Bitcoin was to create a public accounting ledger that records who owns what, and keeps track of all transactions. Money is the common knowledge stored in the Bitcoin ledger.

At Nervos, we want to take this one step further and store more kinds of common knowledge (e.g. digital assets, smart contracts, crypto proofs for arbitration, identities, etc.) on the Nervos CKB.
This is different to current blockchains which are fundamentally fixed, once they are built.

While they will be upgraded over time, their structure will generally remain the same.
To see the challenge this brings, we can look at how difficult it has been to bring Segwit to Bitcoin or Wasm to Ethereum.

CKB takes a step back. Scripts are far more primitive than smart contracts in Ethereum, but carry a significant benefit:
flexibility. Almost all algorithms and data structures are implemented in CKB scripts stored within cells.

On CKB, if you are not satisfied with fundamental functionality, such as a signature algorithm or hash function, just roll up your sleeves and build what you need.

CKB is like an organic construction, rather than a work of traditional engineering.
It allows the network to evolve at its lowest level, and for there to be continual adaptation and adjustment from the ground up.

This is the first in a four-part series that breaks down the architecture of Nervos and why it works as a blockchain platform for today, and into the future, Stay tuned for part 2:
Why Nervos Works: Layer 2 for Flexibility and Future Proofing

Hello Godwoken: DIA Oracles Available in the Nervos EVM Layer

We are thrilled to announce the deployment of DIA’s data infrastructure into Godwoken, the EVM layer-2 blockchain by Nervos.



Update 31.03.2022: DIA’s open-sources oracles have been successfully integrated with Godwoken, the Nervos Network EVM Layer.
Decentralised applications built on top of Nervos EVM layer can now natively access DIA’s broad set of data feeds, including price feeds for 6k+ digital assets, 20k+ traditional financial assets, a range of lending rates, FX rates and other data feeds.

Try now the DIA demo oracle on the Godwoken Testnet: 0x96c5f1e50c4393efa890699cd9aecf3fb58dcb99

The Nervos Network is an open blockchain platform to build applications that are decentralised, autonomous and universally accessible.
Nervos aims to create an all-encompassing build architecture that allows dApp developers to build once and reach all users, everywhere.
The Nervos blockchain is formed by two main components: Nervos CKB and Nervos Godwoken.

On one hand, the Nervos CKB is a layer 1 proof-of-work public blockchain protocol: any crypto-asset can be stored with the security, immutability and permissionless nature of Bitcoin,
while enabling smart contracts, layer 2 capabilities and capture the total network value through a unique crypto-economic “store of value” design and native token, the CKByte.
On the other hand, Godwoken is a newly launched, Ethereum-compatible layer on top of Nervos allowing ETH dApps the ability to port to CKB with a generic framework to build roll-up solutions upon Nervos CKB.

We are excited to announce that DIA’s trusted oracles services will be integrated into Godwoken, the EVM layer-2 blockchain by Nervos.
This new deployment is set to provide a new reliable oracle service for dApps building on this layer, or porting over from Ethereum.
This collaboration will expand Nervo’s oracle offering and enable dApp builders to access DIA’s broad set of more than 5.000 data feeds on Nervos’ layer-2 Godwoken.

“It s pleasing to be working with so many great companies who want to help build out our network and support our burgeoning ecosystem,”
said Nervos co-founder Kevin Wang. “We all know the importance of oracles in the DeFi world, and as we look to grow out our own DeFi offering,
it is great to know that developers will have choices when they choose to come to Nervos”

“The DeFi ecosystem is witnessing a growing number of scaling solutions surge in the last months, focussed on solving the interoperability and scalability issues of the blockchains,”
mentions Michael Weber, DIA Association President. “We are very excited to contribute to these new exciting ecosystems like Nervos by deploying DIA’s oracle data provision into these networks.”

Nervos and XP.NETWORK Partner to Expand Multi-Chain NFT Offerings

The NFT space is arguably one of the fastest growing sectors of the blockchain ecosystem.
And with this, we are excited to announce our latest partnership.
Nervos Network and XP.NETWORK will be partnering to integrate an NFT bridge between the two platforms.

The bridge will allow Nervos to add an even greater variety of NFTs to the platform through XP.NETWORK,
giving access to other chains. Nervos’ multi-chain approach to growing out the ecosystem is perfectly suited to
integrating this bridge and will fit in well with our desire to expand NFT offerings on Nervos.

Bringing You More NFT Opportunities

XP.NETWORK aims to turn the growing NFT market into an accessible and easy-to-use place through their
chain-agnostic bridge designed specially to let NFTs flow freely between networks and wallets while avoiding complications such as different NFT standards.

This approach to multi-chain NFT application is similar to Nervos’ general multi-chain strategy, which begins with the Force Bridge.
Being able to integrate with XP.NETWORK through the NFT bridge is like a gateway to multiple different NFT opportunities, on a variety of different chains.

This is a huge boost to Nervos’ own growing NFT ecosystem, and is a move that is predicated on massive multi-chain growth potential.

“At Nervos, we strongly believe that the future of blockchain is multi-chain, so we are always looking to work with projects that are
helping connect and remove barriers to interoperability. With XP.Network and their ability to provide a simple user infrastructure
for a burgeoning multi-chain NFT world, we believe this will open up many exciting opportunities for our community” explained Kevin Wang, co-founder of Nervos.

About XP.NETWORK

Since it went live in 2021, the XP.NETWORK bridge has become the world’s most potent NFT bridge with over a dozen connected chains,
supporting hundreds of dApps – making it the ideal superhighway that turns every chain into a central intersection of information.

Understanding Nervos’ 2022 Roadmap: With Chief Architect Jan Xie



Last week we held a successful AMA with our Chief Architect, Jan Xie. He answered general questions about Nervos and its architecture, our goal of user simplicity, the future of interoperability, and much more.

We would like to share some of the updates from January on the 2022 roadmap, as well as some of his thoughts on Nervos and the blockchain ecosystem in general.
This article should help you get a much better understanding of what is going on in the Nervos Network engine room at the moment.

Some quick Updates from Jan!
- 100% compatibility between Godwoken and Metamask is on its way. Estimate is testnet launch in March and mainnet launch in Q2.
- Progress is being made on Force Bridge to Bitcoin. The asset bridge is easy, but it is the work on enabling Bitcoin users to operate Nervos dApps like we enable Ethereum users that is hard.
- We are working on zkevm (A virtual machine that runs on the zk Rollup network) and hopefully will see that in the next year or two.

Nervos as Layer 0 / Security Layer to the Blockchain Ecosystem?
The Nervos Network is a platform that identified and addressed issues currently dogging the blockchain ecosystem, right from its genesis.
Proposing ‘State Rent’ to beat the State Bloat on Ethereum, as well as other innovations makes Nervos well primed to to be a base layer in a blockchain ecosystem that could be multi layered.

“CKB can definitely be used as a security anchor or "layer 0" of other blockchains,” explains Jan. “You may notice that Godwoken and Axon are both L2 frameworks that can be used to build application specific chains on Nervos.

“Besides the shared security provided by CKB, building on Godwoken/Axon can also enjoy the benefits of Nervos interoperability 2.0 and access to a larger user base..”

“By the way, I don't like the term ‘layer 0’. There were two definitions of layer 0 in crypto: First, a p2p network/protocol that can be used by many blockchain networks. And two, a shared security layer under all other blockchains.”

“The first definition is a misconception because a p2p network is not a layer parallel with layer 1/2; the second definition implies a single ‘layer 0’ blockchain worldview which I disagree with.

There will be multiple layered networks each has its own layer 1 but no one can rule them all.”

Flexibility Leads to Simplicity
One of the goals of Nervos right from the beginning was to create a blockchain platform that can provide a seamless internet-like expereince. This means that it is simple to use, flexible and powerful.
Current blockchain platforms and ecosystems are still very complex and niched, requiring a lot of prior knowledge to get the most utility out of their ecosystem. Nervos wants blockchain to be as easy as sending an email and this all starts with flexibility.

Nervos will make its ecosystem as simple to use as possible by building a layered network and making layer 1 as flexible as possible,” added Jan.
“Security, decentralization and UX are conflicting design goals and the best way to get all of them is divide-and-conquer or achieve them on different layers.”

“With layer 2, middleware and user interface, complicated technical details can be hidden from users. UX can always be optimized or improved at the upper layer.
You don't know how SMTP works but you can use Gmail. You don't know how the TCP handshake is completed but you can watch Netflix.”

“The Internet is as complicated but upper layer protocols and applications hide those details.
The difference between the Internet and blockchain is we have the goal to preserve security and decentralization as much as possible while building apps on top.”

“The extra goal requires a flexible layer 1, otherwise the upper layer applications would have to rely on centralized intermediaries to realize a smooth user interface.
That's why projects like Unipass, an email based web3 identity system, can only be built on CKB without any centralized intermediary.”

CKB Light to Bring More Applications
The roadmap spelled out the path towards the much anticipated CKB light client.
The first protocol update this year will lay out the groundwork for a fly client protocol and CKB light client.

The CKB light client is a long-awaited feature of CKB with the potential to bring the user experience to a whole new level, without sacrificing decentralization.
 It also means new possibilities for dApps on Nervos.

“I would be excited to see the use of CKB light client in mobile, browser and embedded environment,” said Jan. “With CKB light client on mobile we can build easy-to-use payment dApps to facilitate p2p payment,
based on permissionless off-chain payment networks.”

“The payment dApp can integrate with Unipass to support transfer between decentralized email-based identity, or DAS for user-friendly names and sub accounts.
Any UDT, NFT or stablecoin can be transferred easily in a trustless and friendly way.”

“With CKB light client in web browser developers would be able to build trustless web or extension wallet, with no dependency on any centralized API service.
Or we can build a browser extension to support visiting websites with DAS names thereby decentralizing the Internet's domain name system completely.”

Nervos as an Institutional Platform?
The growth of blockchain and cryptocurrency adoption has seen a lot of interest from institutional entities,
but they require rather specific process checks, such as permissioned protocols, AML/KYC and others that are common in the traditional finance world.

It’s conceivable that new institutional focused layers could be built on Nervos as its foundation is rooted in providing
 a broad and flexible platform and solutions could easily incorporate some of the required features from institutions automatically into the layer.

Jan shares his thoughts on potentially tailoring aspects for institutional use cases in the discussion and says “I like the idea of having solutions optimized for institutional use,” says Jan.
“Godwoken, Axon and SMT dapp are all general frameworks with very open licenses, any team should feel free to package them into business solutions that could be geared toward institutions.

A Big Year for Nervos
2022 marks the fifth year of the Nervos Network. This is a nice milestone to tick off, but it also coincides with a year that we see as being fundamental to our growth and establishment in the blockchain and Web3.0 space.
From the roll out of our technology, to the growth across our ecosystem and the traction we are gaining in the space, we feel well primed to deliver on the 2022 roadmap and to make a big impact in this ever changing arena.

Our partnership with @sifchain, an Omni-chain #DEX built on @cosmos, will bring about a #Godwoken x #Sifchain bridge that will expand #Nervos’ #blockchain interoperability plan 🔥 and that will allow:



✅Moving assets freely across separate chains
✅Projects on #Cosmos will be able to transfer their tokens to Nervos;
✅ and access various projects within our ecosystem and vice versa.

#Web3con
Week has started, and we're excited to 📣 announce Eric, our Head of Developer Relations at #Nervos,

Nervos Network 2022 Roadmap



The Nervos Network has been ticking off major milestones since its foundation and last year was arguably,
the biggest year for Nervos in terms of growth through major releases such as Force Bridge and Godwoken.
With these major milestones achieved in 2021, the doors are open for even more projects to take advantage
of a much more flexible and broad reaching multi-chain ecosystem this year.

Now in 2022, the Nervos Network is looking to take the platform even further ahead.
New innovations across both the Layer 1 and Layer 2 chains are in the works right now.
Improvements in interoperability will expand the reach of the Nervos community through
additional bridges to new chains and are close to being launched. Finally and most importantly,
the Nervos Network is continuing efforts on the cutting edge of crypto research to transform and improve blockchain technology to lead the way for the entire industry.

As you’ll see in this roadmap, the Nervos Network is clearly committed to pushing the boundaries in blockchain technology through these milestones.
These focused efforts are geared towards building a multi-chain solution that will make Nervos Network the ultimate platform where a diverse ecosystem of dApps will flourish.

Layer 1 / CKB (Common Knowledge Base)

CKB Major Protocol Update One
The first CKB Major Protocol Update began development in 2021 and is planned for release on mainnet in early 2022.
This will occur after the final audit and coordination within the community has been completed.
Lina (the name of the current L1 version) has been serving CKB for over 2 years now but now will step aside to make way for a new hero to be announced.

This first protocol update lays the groundwork for a flyclient protocol and CKB light client.
The CKB light client is a long-awaited feature of CKB with the potential to bring the user experience to a whole new level, without sacrificing decentralization.

The Nervos light client will use minimal resources via a flyclient protocol design, and thus is friendly to mobile, web and embedded environments.
Thanks to PoW (proof of work) and cell model structure, these light clients are much easier to build on CKB than on other blockchains.

CKB Major Protocol Update Two
In 2021 Q4, the CKB team also began the development of CKB Major Protocol Update Two, with an estimated mainnet release date of 2022 Q4.
One major aspect of this protocol update is its upgrade to RISC-V V-extension (RVV) for the CKB-VM.

RVV is the key to CKB’s cryptography abstraction approach. With RVV, cryptographic algorithms implemented as on-chain scripts can run faster in CKB-VM.
This means that certain cost-prohibitive cryptographic operations such as pairing, which are the basis of many zero-knowledge proof systems, will now become possible on CKB.

This update marks another significant integral improvement in the development of the Nervos Network.

These two protocol updates on CKB’s Layer 1 are integral and lay the foundation for scalability improvements on the Layer 2 architectures.

Scalability and L2s

Axon
Axon is a Layer 2 sidechain SDK created by the Nervos Network. The development of Axon first began in 2020 with Axon Prototype One followed by Axon Prototype Two in 2021.
Axon is designed for high throughput applications such as gaming or social networks while maintaining its own data availability layer. (Axon transactions are not stored on CKB, the Layer 1 chain.)

During its prototype phase and the launch of Godwoken, many learnings were made that helped pave the way for the next Axon development sprint.
In Axon’s current design, the data availability solution is separated from the sidechain protocol to be an independent project.
With this separation, the first stage of Axon will be a much simpler sidechain with UDT (user defined tokens) staking on CKB.
This separation also allows the possibility of many novel use cases.

With Axon, DApp developers will be able to use the Axon toolkit to create and distribute chain-specific
UDT on CKB with chain token holders able to stake UDT to become an Axon chain validator or just deposit it into the Axon chain for use in dApps.

Just like Godwoken, Axon will be 100% Ethereum compatible as applications being built on Axon will inherently have multi-chain capability.
The Nervos team looks forward to launching this new Layer 2 with a major event and bringing brand new dApps onto it through hackathons planned over the course of the year.

SMT dApps
SMT dApps are able to scale smoothly and are made ready for mass adoption. In 2022 Nervos will identify common patterns and provide even more support and tools for SMT dApps.

To explain better if Godwoken and Axon are the off-the-shelf generic layer-2 solution, SMT dApps are the highly-customized layer-2 applications based on SMT (Sparse Merkle Tree).
The sparse merkle tree is a highly optimized, well-tested, and audited data structure library introduced by the Godwoken team 2 years ago, to be used for state aggregation in Godwoken.

With the help of SMTs, dApps or layer-2 chains can move their state off-chain while keeping state integrity.
SMTs turns purely layer-1 dApps into off-chain dApps between layer-1 and layer-2 (“layer 1.5”). Examples of applications that are already using SMTs are Mibao NFT by Nervina,
Unipass V3 by Lay2 and the upcoming Sub-account Support by Decentralized Account Systems (DAS).

In addition to the current SMT dApp design, Nervos researchers will expand SMTs with additional optimizations to push the theoretical limit and formally prove its optimality.
More information on these research results will be released in 2022.

Developer friendly zkSNARKs
The need for developer-friendly zkSNARKs is becoming increasingly clear with privacy on the blockchain remaining an important piece of the overall puzzle.

Zero-Knowledge Succinct Non-Interactive Argument of Knowledge, also known as zkSNARKSs,
is a relatively new form of Zero-Knowledge cryptography that allows one party to prove it possesses specific information without revealing that information to another party.

With “Polynomial IOPs for Linear Algebra Relations” published in The International Conference on Practice and Theory of Public-Key Cryptography (PKC) 2022,
Nervos has made steady progress in designing more efficient and developer-friendly zkSNARKs.

Nervos will present two new tools for the development of these zkSNARKS, named VOProof and VORAM.

Specifically, VOProof provides a simple and intuitive language for describing the zkSNARK design and a compiler transforms this language into the working code of the zkSNARK.
Based on the VOProof toolset, Nervos has developed VORAM,
which focuses on the automatic creation of zkSNARKs-based on RAMs—a class of computational models that are friendly to programmers

Interoperability
Building on an improved backbone of Layer 1 and Layer 2 improvements the Nervos Network will reveal additional
interoperability improvements as this area is one of Nervos’ defining characteristics to create a multi-chain ecosystem.

Godwoken Ethereum Equivalence
The Nervos Layer 2 solution named Godwoken took center stage in late 2021 with its low fees and quick runtime.
Now in 2022 Nervos plans to build upon that early success to launch the next version of Godwoken and bring it to the next level.

This newest version of Godwoken will be 100% Ethereum compatible, allowing for conveniences such as full Metamask support,
simpler contract deployment solutions and tighter integration with the existing Ethereum ecosystem.

In addition to Ethereum compatibility, the new version of Godwoken will improve upon its Web3 RPC scalability
to increase data query and transaction capacity to meet the challenges of an ever-growing ecosystem.

Force Bridge & Cross-chain Liquidity
Force Bridge, a cross-chain bridge network that helps users move assets between Layer 1 and Layer 2 blockchains plays an integral part in the development of the Nervos platform.
The team views Force Bridges as providing tremendous opportunity to a variety of chains where there is little to no existence of dApps.

Now in 2022 the team will continue to add additional chains through new Force Bridges that will enable an even more diverse ecosystem of communities.
This key connection with other chains will provide numerous opportunities for new people to utilize their assets within the Nervos ecosystem and, at the same time,
bring even more cross-chain liquidity to the platform.

Research
Research is a critical and fundamental building block of Nervos. Every day the team continues to push ahead across many highly technical research areas to further improve the Nervos platform.
With these efforts, such as helping found the UTXO Alliance,
Nervos will be taking more steps in 2022 to strengthen research in Proof of Work, Extended UTXO Model and payment channels.

Strengthening Proof of Work
Nervos CKB (Layer 1) operates on a bitcoin-like proof of work model (PoW) for a zero-compromise solution for consensus.
This updated consensus model was named NC-Max after the founder of bitcoin, Nakamoto.

The Nervos Network is looking forward to its consensus protocol NC-Max being published at Network and Distributed System Security (NDSS) Symposium later in 2022, one of “the big four” security conferences.
This will further cement Nervos’ position as a leading PoW researcher.

However, NC-Max is not the end of the journey. Nervos researchers have identified several areas to improve Nervos CKB’s current consensus mechanism.
This includes polishing its difficulty adjustment mechanism (DAM) ahead of its academic debut publishing in 2022.

Nervos is also working on a series of security analyses with different collaborators in academia.
On the network layer, Nervos has identified a security-performance tradeoff (similar to that in non-NC-Max blockchain protocols in blockDAG consensus protocols)
which were previously believed to be immune to the tradeoff. Conversely, on the consensus layer,
research will continue to explore the use
of tools in artificial intelligence to analyze the security of consensus protocols and release vulnerabilities of existing consensus protocols.

Cell / Extended UTXO Model
Nervos CKB (Layer 1) utilizes an Extended UTXO model which enables a number of important collaborations.
In 2022 in collaboration with the Cardano research team,
Nervos began a research project comparing the UTXO model and the account model even prior to the inception of the UTXO Alliance.

Together they achieved some preliminary results but didn’t manage to formalize them into a full report.
Now that the Nervos CKB toolchain is more complete, there are plans to demonstrate UTXO’s superiority not only conceptually but with experimental results.

The Nervos Network hopes that the upcoming paper based on these experiments will serve as an academic manifesto of the UTXO Alliance.
This paper will not only be among the earliest demonstrations of this model but also serve to be an advocate of the UTXO Alliance.

Payment Channel Network
Payment channel networks (PCN) have always been on the Nervos roadmap because Nervos consider it a necessary component of Layer 2 infrastructure.
Many prototypes in previous years were completed in order to test ideas combining PCN with UDT and other Layer 2 networks.
As this is a very important area of interest for Nervos, research will continue this year with new developments being shared in the later part of 2022.

Closing
With many new major milestones set for 2022. Nervos is on a path to creating even more value across the platform.

Each of the developments these key areas outlined will enable Nervos to take another step closer to achieving its overarching goal of making the Nervos Network as simple,
adaptable and scalable as possible.

In 2022 as Nervos continues to deliver major breakthroughs in the blockchain space,
the team couldn’t be more excited to have shared a glimpse of the future of the Nervos multi-chain vision.

Send and Receive $CKB in Opera Android Browser



We are excited to let you know the first phase of our integration with Opera is complete!
This follows on from our partnership with the multi-platform web browser that we announced last year.

Starting today, Opera’s millions of users can send and receive $CKB within the crypto wallet built into the Opera browser on Android.
Once the next phase of integration is complete, the wallet will support token transactions on Nervos’ Layer 2, Godwoken.
Opera’s developer-friendly browser wallet will support $CKB in the future to attract blockchain developers.
Nervos’ Layer 2 will also be integrated in Opera’s newly announced Crypto Browser Project, a dedicated Web3 browser currently in beta.

Nervos is the newest blockchain after Bitcoin, Ethereum, and Celo to be supported by the browser.

With Nervos’ Layer 1 integrated into Opera’s flagship Android browser, users will be able to easily send and receive CKB tokens via a seamless user interface,
with no need for any third-party browser extensions or wallet applications.
Additionally, users will have direct access to Nervos’ ecosystem of dApps, which supports NFTs, DeFi, gaming, and other applications.

The integration with Opera is a big step in bringing Nervos and its associated ecosystem to people in an easy-to-use and accessible way.
Opera, as a mainstream browser focused on Web3.0, with hundreds of millions of users, is important not only for the Nervos network but also the success of the future decentralized economy.

Crypto Exchange Bybit Lists $CKB Perpetual Futures for Trading

We’re excited to reveal Bybit, a leading global crypto exchange, has listed $CKB, the native token of the Nervos Network, for perpetual futures trading.
Starting today, traders can access the perpetual futures trading pair CKB/USDT on Bybit, with CKB/USDC expected to follow at a later date.

The listing comes as more traders, both in crypto and in traditional finance, take an interest in crypto derivatives, and specifically perpetual futures.
Unlike a typical futures contract, perpetual swaps don’t have an expiration date, eliminating the need to consistently reestablish a long or short position.
Furthermore, traders can potentially generate profits even if the cryptocurrency market is down.

Bybit boosts over 5 million users and more than 10 billion in daily trading volume. And is the first trading platform to list $CKB perpetual futures,
establishing a new way for traders and $CKB holders to engage with and invest with the token.

“Giving our community new ways to trade and invest in $CKB is an important part of our ecosystem’s growth,” said Kevin Wang, co-founder at Nervos.
“The demand for crypto derivatives continues to surge, so Bybit’s new $CKB Perpetual Futures listing will help to meet the needs of the investors and traders in our community.”

NervosPerp Campaign

To encourage users to take advantage of the new $CKB perpetual futures listing, Bybit has launched NervosPerp, a new trading campaign.

From February 15-28 at 23:59 UTC, users are invited to trade CKB/USDT contracts for more than $1,000 USDT to receive 10 USDT.
Users who register new Bybit accounts will get 20 USDT total.

Users can also participate in the Top 100 trading volume competition by trading CKB/USDT contracts.
The top user will receive 1,000 USDT and users ranking second through 100th place will receive 100 USDT each.
Overall, users new to Bybit will have a chance to receive up to 1020 USDT from the campaign.

YokaiSwap Launchpad: StableKoi IDO



We are very excited to announce YokaiSwap’s new IDO is launching on 18 February 2022 for StableKoi, the most liquid cross-chain stable swap on Nervos Network.

About StableKoi

StableKoi is the most liquid cross-chain stable swap on Nervos Network and will provide a liquidity foundation for stablecoins and assets from different blockchains.
StableKoi will facilitate the transfer of assets between Nervos and other blockchains.
In addition, users on StableKoi will be able to deposit crypto in the liquidity pool to earn passive yield, token incentives and vote on the governance of the ecosystem.

IDO Details

The IDO will start on 18 February at 2 AM UTC, with 5% of $KOI tokens at the price of $0.000025 per $KOI.
(20% for the community whitelist pool and 80% for the public overflow pool); the IDO will run for 24 hours, from 18 February 2022 at 2 AM UTC to 19 February 2022 at 2 AM UTC.
Once the IDO ends, you will receive KOI, which can be staked on Yokaiswap.com right after for KOI rewards.

KOI Token Info

• Target raise: $1,250,000
• Project valuation: $25,000,000
• Total supply: 1 Trillion
• IDO participation page: https://www.yokaiswap.com/launchpad
• IDO open date & time: 18 February 2022, 2 AM UTC
• IDO end date & time: 19 February 2022, 2 AM UTC

StableKoi Tokenomics

• 5% IDO
• 9% Liquidity reserve
• 25% Team & Advisors (2 years linear release)
• 25% Partnership & Ecosystem
• 36% Mining reservse

IDO — Overflow model

TLDR: Basically, the more CKB/ YOK LP token you put in, the more KOI you will get, and you’ll get back LP tokens that don’t get converted.
In the “Overflow” method, users can subscribe as much or as little as they want to the IDO,
and their final allocation will be based on the amount of funds they put in as a percentage of all funds put in by other users at the time the sale ends.
Users will receive any leftover funds when they claim their tokens after the sale.

It’s possible to receive no tokens at all: If you commit a very small amount of LP tokens compared to the total amount committed by others,
your contribution may be such a small part of the total that you may not qualify for even a small portion of the tokens sold.
In such a case, you will still be able to reclaim all the YOK/CKB LP tokens you committed.

How to participate StableKoi IDO?

To participate, you will need to prepare your YOK/CKB LP Token, see this detailed guide on becoming a liquidity provider (LP) on Yokaiswap.com: ​​
https://medium.com/@yokaiswap/yokaiswap-launch-feature-guide-2b30fe23b148
There are 2 pools for the IDO: overflow pool (80%) and whitelist pool (20%).

Step by step guide:

1. Visit Yokaiswap.com/launchpad
2. Start Staking and get YOK/CKB LP token
3. Commit YOK/CKB LP token
4. Claim your tokens and receive leftover LP token
