Verge Cryptocurrency Hit By 51% Attack, Loses 250,000 Tokens 706

The cryptocurrency Verge — which prides itself on “security/anonymity/privacy” — was hacked yesterday. In a short period of time, the attacker made off with around 250,000 coins.

The hack was discovered by “ocminer,” a poster on Bitcointalk forums, yesterday afternoon. According to ocminer, the attacker took advantage of “several bugs” in Verge’s code to mine an extraordinarily large number of new blocks on Verge’s blockchain, in turn rewarding him/herself with a large number of coins over a very short period of time.

Despite registering large gains as of late, the cryptocurrency experienced what’s been dubbed a “51% attack” which wiped more than 22% of its value. The company came to its defense, calling the breach a “small hash attack” that has been “cleared up now” on Twitter. This isn’t the first time the coin developers have been in hot water. Just a few weeks ago their official Twitter account was hacked.

51% Attack

Ocminer and several media outlets called this a 51% attack, which is notable because this type of attack is theoretically possible on other blockchains which rely on proof-of-work (PoW) validation mechanisms. That said, even though this attacker technically managed to capture the majority of mining power on Verge’s network, this type of attack is unlikely to work with Bitcoin. 

Typically, PoW-based cryptocurrency systems are quite robust. The problem is that if one miner (or mining pool) were to capture the majority of the network’s mining power — as has happened with Verge — they can have a huge impact on the network, including spending coins that were already spent in what’s called double spending.

Verge uses five different cryptographic algorithms for mining, switching to a new one for every block, but the attacker figured out a way to fake the timestamps of his/her blocks, permitting them to be mined all with one algorithm. Because of this, he/she was able to capture the majority of the network’s mining power with far less computing power than would normally be required. 

The attack is particularly serious as it requires a hard fork to exclude the blocks the attacker has mined. It’s also notable because it shows that even a seemingly foolproof PoW system can be compromised. Ethereum has already had one hack of large magnitude in its history, while Bitcoin, on the other hand, has mostly stood the test of time through its nine years of existence.

Metatime Raises $11M in Private Funding to Enhance Web 3.0 Ecosystem 994

Metatime has announced that it has raised a total of $11 million in investment through two seed sales held to develop the Web 3.0 ecosystem. The funds raised in the two seed sale rounds held before the initial public offering will support Metatime’s goal of expanding its Web 3.0 product range.

Under the umbrella of Yıldız Tekno GSYO A.Ş., leading investors including Halkbank, Kalyon Holding, Yıldız Technical University, and Türk Telekom provided a total of $11 million in funding to Metatime. Also, more than 10 angel investors participated in the two-stage seed sale. The locks of 10% of the MetaCoins (MTC) sold in the two-stage seed sale will be opened after the final public offering, which will end on November 11, 2023. The remaining 90% will be linearly released for use starting from the main launch date of November 11, 2023, for a period of 225 days.

The demand collection process, which started on March 3 and will continue until March 23, is ongoing. With high demand for the first private sale of MTC, investors are vying to own MetaCoin at a fixed price of USD 0.07. Metatime has released all the details of the private sale ahead of the demand collection that will end on March 23.

Metatime Co-Founder and CEO Yusuf Sevim said, “We are grateful to all the seed investors who supported us. Their investments will help us break new ground in blockchain technology and expand the ecosystem. We started our investment process with the first demand collection on March 3, and we are very pleased with the interest the campaign has received.

Can D5 Exchange Drive Forward Crypto Trading in the Wake of US Regulatory Crackdowns? 1234


The recent SEC crypto crackdown has hit many centralized exchanges (CEX). This scrutiny is drawing traders to decentralized exchanges (DEXs). However, insufficient liquidity, impermanent loss, limited trading functions, and high gas fees may make it difficult for users to migrate.

The first decentralized liquidity aggregator with order book and AMM mechanisms is Gridex Protocol-based D5 Exchange, that solves DEX issues by offering CEX-like trading.

The rise of the DEX

In November 2022, the FTX collapse massively damaged the credibility of CEXs. The same month, Block reported that trading volume for DEX’s increased 93s% to $65 billion.

Emerging DEX projects with strong technological innovation will have higher growth potential than the older players in the next bull market (such as Uniswap and SUSHI). One notable newcomer is the D5 Exchange.

Three-Pronged Approach: Liquidity Aggregation, Hybrid Trading Model, Ultimate User Experience

So, despite their loss of credibility, why can’t DEXs beat CEXs? Lack of liquidity, gas fees, and impermanent loss are some issues affecting DEXs. D5 Exchange, the first aggregator to combine order book and AMM functions, aims to revolutionize on-chain crypto trading and accelerate the transition from CeFi to DeFi.

D5 Exchange Hybrid Trading Model: AMM + Order Book

Most DEX trading execution models are either order book or AMM. Both have advantages and disadvantages.

AMMs allow trading in illiquid markets. Traders can close orders without a counterparty match, saving gas and completing transactions in one trade. However, large traders may suffer from slippage, and LPs may suffer from impermanent loss, the pool lacks liquidity. AMM-based DEX products include Uniswap and Balancer.

An advantage of order books is that traders can place limit orders and wait for them to be executed at the best price. If the market is liquid, trades can be done fast and slippage-free. They are commonly used in CEXs and are therefore known among mainstream traders. A disadvantage is that they may need multiple orders to complete, meaning high gas costs. Projects such as Injective and dYdX use order books.

D5 Exchange is the first exchange to combine the advantages of both AMM and order books and is the Ethereum ecosystem’s most liquid and dynamic DEX because its automatic router can aggregate liquidity from external DEXs like Uniswap (V2+V3) and Curve to achieve internal liquidity and the best exchange rate.

GMOB+GPLM: Innovative Dual-Model Order Book Algorithm

Gridex Protocol powers D5 Exchange order books, the first Gridex-based DEX. Only Gridex has an Ethereum order book.

Gridex’s Grid Maker Order Book (GMOB) is a major improvement over centralized platforms’ Central Limit Order Book (CLOB). On-chain CLOB requires significant resources. Semi-centralized CLOB platforms like dYdX match transactions off-chain and synchronize the results on-chain to solve this problem. This approach has systemic risks and goes against DeFi.

The GLOB model uses the “Grid Price Linear Movement” (GPLM) algorithm to achieve decentralization. based on L1 transactions – a huge improvement over L2 and off-chain DEXs. Gridex Protocol’s gas level matches CFMMs, while the GPLM algorithm doesn’t affect transaction settlement efficiency or user costs. Gridex Protocol’s gas level is comparable to or lower than Uniswap’s, which uses the AMM mechanism.

GMOB and GPLM allow D5 Exchange to offer a revolutionary on-chain trading experience. With this innovation, the Gridex Protocol is poised to lead the decentralized order book market.

Maker orders are used on Gridex, allowing traders to buy and sell orders above and below the market price. Also, maker orders can be placed at the current price, and if the market price changes, they may be filled. Only when maker orders are placed at the bid/ask price may they slightly diverge from trader expectations, but the impact is negligible.

Ultimate Usability

D5 Exchange’s UX design is comparable to CEXs; smooth, but with connecting wallets letting users trade immediately, and zero transaction slippage.

The Grid mechanism of D5 Exchange divides grids into three types based on price range granularity: 0.01%, 0.05%, and 0.3%, suitable for different tokens. Stablecoin trading pairs have low volatility, so a finer grid speeds execution. To maximize transaction fee income, Maker orders for high-volatility trading pairs should use coarser grids. The market will suggest grids for orders. Cancelling orders helps reorganize liquidity and avoid short-term losses. The D5 Exchange optimizes order execution and transaction fee income.

GDX Listing

Gridex’s native currency, GDX, was formally listed on the D5 Exchange, the first on-chain trading protocol for the Ethereum ecosystem, on March 15th. According to CoinMarketCap data, the price of GDX rocketed to $1.97 at its high, an increase of over 1,000 % from its listing price of $0.16. Furthermore, according to data from Abiscan, over 10,700 wallet addresses own some GDX. To facilitate trading on D5 Exchange, Gridex has launched trading pairs such as GDX/USDT, GDX/USDC, and GDX/GMX.

With a maximum supply of 200 million, 30% of GDX is set aside for project development and promotion, core contributors, and early investors. The other 70% is set aside for community distribution, which includes airdrops, PoS incentives, and maker awards. The maker rewards campaign began on Arbitrum One on the GDX/ETH trading pair (0.05% grid) on March 15th, 2023. The total prize pool for the maker rewards campaign is 54 million GDX.


In conclusion, D5 Exchange’s forward-thinking approach to combining AMM and order book models will help the DEX industry grow. The D5 Exchange does not solve all DEX industry issues, so industry builders must work together. The D5 Exchange and Gridex Protocol, leaders in the DEX industry, are developing DeFi together.

Signum Digital Obtained the Approval-In-Principle from the SFC on the First Security Token Offering and Subscription Platform in Hong Kong 2012

Coinstreet Holdings Limited (“Coinstreet”) is a leading global professional consultancy firm and solution provider in the digital asset sector, and Somerley Capital Holdings Limited (“Somerley”, stock code: HK.8439) is a leading financial group in Hong Kong with an established track record in the corporate finance advisory space in Greater China. Signum Digital Limited, (“Signum Digital”) is the joint venture of Coinstreet and Somerley, and has received an approval-in-principle from the Securities and Futures Commission (“SFC”) for its security token offering and subscription platform. This is the first of its kind in Hong Kong.

Security tokens are a new type of blockchain-based virtual asset that may represent ownership in actual assets, such as real estate. The link to real-world assets may reduce the risk to prospective investors, assist their due diligence process and underpin the market value of the offering. Blockchain technology provides a transparent and efficient basis for digital assets to be traded in real time. Transactions are permanently and immutably recorded on blockchain, through cost efficient mechanisms and programable governance in the form of automated smart contracts. Subject to satisfying the conditions for final approval from SFC, this license will allow Signum Digital to operate a security token offering and subscription platform under the brand of “CS-Pro” (, serving professional investors and providing funding for issuers with qualified projects in Hong Kong and international markets.

Samson Lee, CEO of Signum Digital and Founder of Coinstreet commented, “In today’s financial market, SMEs face many challenges in traditional fundraising channels, and professional investors also have limited options for high quality alternative investment opportunities. Signum Digital aims to fill such a gap and we believe the CS-Pro security token offering and subscription platform can add much value to Hong Kong and international security token project issuers and professional investors.”

Martin Sabine, Chairman of Somerley, commented: “We believe there is considerable pent-up demand among professional investors to deploy a proportion of their portfolio into digital assets. The events of 2022 may have shaken their confidence in parts of the crypto world but not their belief that digital assets will play a pivotal role in the future of finance. STOs distributed by Signum Digital, backed by real assets and income streams, are in our view a medium risk way of participating in these future opportunities.”

Clara Chiu, CEO of QReg Advisory and Former Head of Fintech and Licensing Director of the SFC said, “We are proud to have advised Signum on the design of their STO platform and helped them secure the first-ever SFC licence for such a platform in Hong Kong. We are pleased to work with Signum which shares our passion for innovation and our commitment to excellence. The SFC’s license to Signum’s STO platform is truly ground-breaking, and we believe that it has the potential to revolutionize the way that businesses raise capital. We are thrilled to be a part of this exciting development in the industry!”

Combining Coinstreet’s security digitization and asset tokenization expertise with Somerley’s grounding in best practice for conventional corporate finance, Signum Digital will offer professional investors fully compliant asset tokenization offering and distribution model which may cover a wide array of asset types and classes ranging from private equities, debts, income bearing notes, real estate, investment funds, commodities, and fixed assets, capital equipment, to carbon credits, arts & collectibles and other alternative investment assets.

Gridex: An on-chain order book protocol, the catalyst for DeFi mass adoption 2549

With the increasing popularity of decentralized finance (DeFi), the demand for decentralized exchanges (DEXs) with a better user experience and lower costs has become one of the primary goals of many blockchain projects. Gridex Protocol has taken a step forward in addressing this need by launching an on-chain order book trading protocol that offers robust decentralized attributes.

A new type of trading protocol using a dual algorithm framework

The Gridex Protocol team has introduced a new type of DEX using their dual algorithm framework, providing a solution to the shortcomings of existing automated market maker models used by mainstream DEXs. The team designed the GMOB model and GPLM algorithm to solve the problems of impermanent loss and high slippage issues preventing users from entering DeFi.

Centralized exchanges (CEXs) usually use a CLOB model for the matching engine algorithms. However, the CLOB model requires significant resources, making it impossible for them to be deployed and run on blockchain networks. The GMOB model improves the resource consumption problem caused by CLOB, allowing order books to be on-chain.

GMOB limits maker orders to an extremely narrow price range based on percentage limits, adding them to the system order book instead of executing them immediately. This feature increases liquidity in the entire system, like a CEX. Gridex Protocol drives incentives by providing makers with negative transaction fees.

The GPLM algorithm mainly handles transaction execution and settlement, measuring linear proportional relationships between changes in token prices caused by takers within a specific price range and token purchase quantities. Even if all transactions are on-chain, the gas consumption for the Gridex Protocol remains the same as a constant function market maker without imposing a higher cost burden on users.

Gridex Protocol provides clear advantages for users

Gridex Protocol is taking the user experience to the next level with its innovative technology. In the early stages of DEX development, the focus was on decentralization and transparency, but as the market evolved, improving user experience became a top priority.

Gridex Protocol offers a smoother trading experience and lower costs than its competitors. Tests have shown that trading with Gridex Protocol costs the same as Uniswap v3, at around 120,000 gas. However, completing orders with the “collect maker order” feature can save users up to 60% of gas fees compared with adding or removing liquidity with Uniswap v3. This innovative feature means users can save up to 40% on transaction costs by switching from Uniswap v3 to the Gridex Protocol.

The Gridex Protocol order system provides users with three granular options to balance transaction efficiency and fee income: 0.01%, 0.05% and 0.3%. For stablecoin pairs and other trading pairs where quick execution is essential, users can choose finer granular modes. Coarser granular options are also available for high-volatility tokens to obtain increased transaction rewards.

Gridex Protocol‘s native token GDX will list on D5 Exchange on March 15

Gridex Protocol has announced that it will list GDX — its native token — on D5 Exchange on March 15. According to the team, a total number of 200 million GDX tokens will be issued, of which 70% will be distributed to the community for proof-of-stake (PoS) rewards, maker rewards and airdrop rewards. The remaining 30% will be used to reward core contributors and early investors, and for project development and marketing.

According to the development roadmap, the Gridex Protocol team expects to launch a PoS mainnet in the second quarter of 2024, supporting mainstream layer 1s and layer 2s, establishing cross-chain order books, with D5 Exchange becoming the DEX that aggregates liquidity from the entire network.
