Therefore, QuarkChain will be able to provide real-world and real economy services such as transportation cards, gift certificates, local currency, and overseas remittance fees. When this became known, QuarkChain’s token value rose 55.5% compared to the previous day (as of March 17th).

Oracle Perceptron is a platform that connects the DeFi industry and traditional finance by cross-chaining various networks such as Bitcoin, Ethereum, Binance Smart Chain, Tron, and Quark Chain, and by blockchaining the open banking API of traditional finance. Services provided by Oracle Perceptron include Neuron Assets, operators, wallets (enterprise and personal), Explorer, and Payment Gateway. Among these services, there is Oracle Perceptron Wallet, which is a technology that connect various assets with the real economy and resolves the UX/UI problems that hinder the expansion of the DeFi industry. A public key-based structure that integrates public keys used for encryption and private keys used for decryption by integrating and managing digital certificates of PKI is drawing attention as a technology that solves the problems of the DeFi industry. The Oracle Perceptron wallet is available in two categories: personal and enterprise.

With the support of QuarkChain in Oracle Perceptron Wallet’s SDK (a technology that is attracting attention from a multitude of people) many developers and users can easily and conveniently develop and use the core functions of the wallet. In addition, users can safely and conveniently manage and store public and private keys while utilizing various real economy services. An official from CenterPrime said, “As QuarkChain, a stable blockchain platform based on sharding, participates in the Oracle DeFi ecosystem, the expansion of the Oracle DeFi ecosystem that connects various services in the real economy to the DeFi industry is expected to accelerate. We look forward to the Oracle Perceptron as a window to a new world for users of the multitude of QuarkChain platforms.” For more information about CenterPrime, please visit the website (

“We’re ready for Decentralised Finance,” claim traditional financial service institutions


Decentralised finance (DeFi) is now being taken seriously by traditional finance. In a European-wide survey of financial institutions spanning across insurance, banking and trading, 86% are implementing or assessing services built on a DeFi framework.

Of those companies, 31% are reporting an enterprise-wide rollout or have deployed use cases of DeFi. Additionally, 58% of companies are concerned they will lose a competitive advantage by ignoring DeFi instruments.

From the companies implementing decentralised finance, 35% are collaborating with an existing consortium, platform, application or service. 24% are developing their own consortium or platform and 22% are going to collaborate with competitors because the current ecosystem is not compatible with their requirements.

The research, conducted by BCG Platinion (part of Boston Consulting Group) and, analyses the uptake of decentralised services amongst traditional financial institutions. From 400 companies across Europe, 71% with a turnover or balance sheet above £10bn assessed or implemented DeFi, compared with 51% of companies turning over less than £100m.

Of companies assessing or implementing the blockchain technology, 42% are pivoting to a more decentralised approach to asset management. 38% of companies are using it to facilitate faster, more secure, payment processing services, rising to 61% for the biggest companies.

Conversely, 70% believe security concerns over fraud is a challenge preventing company wide adoption of DeFi, and 15% of decision makers strongly believe that whilst decentralised finance is a threat, their companies are against its adoption.

The research also considered the impact DeFi will have on business and operating models and 59% of companies say they will have to implement a new governance structure. But 70% of companies say restructuring the business model or decoupling decentralised finance will increase the speed and lower the cost for financial transactions. 67% said it would open up new revenue streams and 61% said they believe smart contracts are an important business driver for considering or adopting DeFi as a way to execute financial services.

At the same time, a lack of regulation is a challenge for 61% of companies, increasing for companies with a larger turnover or more assets under management. That decentralised finance is over collateralized is also a concern for investment bankers and asset managers, more so than other areas of finance. And sharing their anxiety with a recent FCA announcement, 60% of companies are worried about a lack of recovery mechanisms.

Kris Marszalek, Co-founder and CEO of said, “The research shows that DeFi’s adoption is not limited to just the blockchain industry; traditional financial institutions of all sizes are viewing DeFi not as a competitive threat but rather as a valuable instrument to delivering more decentralized, efficient financial services. This is shown in their warming attitudes towards DeFi and its integral role in future plans for the vast majority of them.”

Kaj Burchardi, Managing Director of BCG Platinion, adds, “As markets evolve towards
decentralisation, there will be a growing demand for approaches like DeFi which can provide a
more efficient and more open way of banking, trading and investing. “It is encouraging to find that financial institutions are already seriously, and strategically, collaborating with the crypto community to begin building a new generation of governance and technologically resilient solutions that will make financial services more accessible.

However, there is still quite some progress to be made in order to bring DeFi into the mainstream especially in security and compliance.”

The survey was conducted by Sapio Research interviewing 411 decision makers with familiarity over decentralised finance and follows up a report highlighting the challenges and opportunities for financial institutions adopting decentralised finance. See more survey findings here.


Delving into DeFi’s Hidden Super Platform


Quietly up against strong competitors, DRK aims to fundamentally transform daily activities of crypto users (and DeFi users in particular) as it works towards its ambition to become an all-in-one super platform in the crypto space. Based on its native chain (DRK Chain), the underlying platform centers around a decentralized cross-chain exchange (DRK DEX) seamlessly integrated with its Dapp ecosystem consisted of DeFi services (DRK Crosschain Swap, DRKompound), games (DRKats, DRocKet, DTrade), a social network reserved specifically for all crypto users (DRKakao), and more.

In its final form, DRK will be where crypto users can earn money 24/7, have fun and connect with like-minded people. The need for such a platform has never been greater. Imagine Facebook, Medium, Telegram, Coinmarketcap and Trustwallet all rolled into one, DrKakao is already in development, designed to connect crypto users and provide useful social features such as regulated P2P trading, and live streaming for crypto KOLs.

As the centerpiece in the grand scheme, DRK DEX has achieved 5.48M monthly views and is supporting 6 coins and tokens (on 4 popular blockchain networks), and 6 trading pairs. Innovations in cross-chain compatibility behind DRK DEX and DRK Swap have solved the headache facing all Defi projects: how to guarantee utility as well as usability and security. Users only need to log in once by connecting with your Metamask wallet to access wallets on all popular blockchain networks (Bitcoin, Ethereum, Tron, and DRK Chain), and do not need to switch networks while trading. The keys of these wallets are generated from your logged-in wallet signature, stored on the client side, and cannot be accessed by any party including the DEX creators.

Seamlessly integrated with DRK DEX, DRK Swap combines the best features of Uniswap with a smart fee mechanism to help liquidity providers mitigate impermanent loss in case of high slippage. Likewise, DRKompound brings Compound enthusiasts a DEX-like and much easier to use interface. On the other hand, DRKats combines elements of DeFi and NFT, allowing users to stake DRK coins in order to receive DRKat NFTs, which can be crossbred and traded freely.

All these high-performance Dapps were and will be built on DRK Chain, which is no less powerful than other popular blockchains, achieving high throughput, smart contract functionality, and compatibility with the Ethereum Virtual Machine (EVM) with support for the rich universe of Ethereum tools and DApps. This makes it easy for developers to port their projects over from Ethereum, and for users to configure applications like MetaMask to work with DRK Chain.

DRK Chain achieves 2 second blocktime with a Proof-of-Stake consensus algorithm and many innovations. Firstly, DaRK privacy protocol uses cutting-edge zero-knowledge proofs to enable private transactions. Secondly, the anti-spam mechanism applies a loyalty point on each address based on the amount of gas that address has contributed to the network, so that the higher the loyalty point is, the less gas it needs to prioritize outbound transactions. Thirdly, the anti-slack mechanism allows any validator node which stops mining blocks to be reported by any address and penalized, keeping validator nodes healthy and the network sustainable.

DRK, the native coin on DRK Chain, has been consistently valued at $0.05  for 3 months with a market cap of $800M, and a daily trading volume of $3M. Currently, 96% of DRK coin supply has been permanently locked in staking, and all newly mined DRK will be staked to prevent inflation. To further popularize its Dapps, DRK Team is considering to list DRK on a major exchange. In the meantime, a few startups are asking to list their own tokens on DRK DEX by paying a fee in DRD, yet another highly demanded token on DRK Chain.
