FTM secures top gainer spot with 8% jump, but market signals caution ahead

Fantom, a scalable blockchain platform for DeFi, surged by 8% on the morning of Aug. 16, making it the top performer in the crypto market.

At the time of writing, Fantom (FTM) was still up 8%, exchanging hands at $0.393 per price data from crypto.news. The crypto asset’s daily trading volume jumped by 84%, hovering around $274 million, while its market cap stood at $1.1 billion, ranking it 70th among the top largest cryptocurrencies.

The token’s price has jumped by 42% since its drop to $0.276 on Aug. 5, when the crypto and stock markets crashed, leading to over $1 billion in liquidations. Despite its recovery to levels last seen on March 21, FTM is still down 88% from its all-time high of $3.46 recorded in October 2021.

Fantom‘s current price positions it slightly above the middle Bollinger Band at $0.3691 and well below the upper band at $0.4581. The lower band is situated at $0.2801.

This suggests that FTM is trading within the typical range of its Bollinger Bands, specifically in the upper half of this range. The price being above the middle band but not yet approaching the upper band could indicate that the market sentiment is moderately bullish. However, the token has not yet shown the strength required to challenge the upper resistance level at $0.4581.

FTM consolidates with neutral indicators, awaiting market catalyst

The fact that FTM remains within the Bollinger Bands indicates that the price movement is within expected volatility levels and has not yet reached a point of being overbought or oversold. The proximity to the middle band suggests a phase of consolidation or a mild upward trend but not a strong breakout.

Additionally, the Relative Strength Index is currently at 49.61. This level is close to the neutral 50 mark, indicating neither overbought nor oversold conditions. This further supports the notion that FTM is in a period of consolidation, with the market undecided on the next significant move.

While FTM is displaying mild bullish behavior by trading above the middle Bollinger Band, the lack of a strong push toward the upper band and the neutral RSI suggests that the token is in a state of consolidation.

The market could be waiting for a catalyst to determine the next direction, whether that be upward momentum to test the upper band or a potential retracement back toward the middle or lower bands. A broader analysis of FTM’s price movement on the daily chart also reveals a falling wedge pattern. The price has experienced a significant decline, dropping 78.59% from a high of $1.22 to a low of $0.26 since March 2024.

On a more optimistic note, the price action of FTM suggests the beginning of a bullish phase, as the token has started to rise from the support trendline. Over the last 11 days, FTM has seen a 33.51% increase, pushing it above the 20-day EMA. However, the recent surge in selling pressure around the $0.40 mark led to a sharp price rejection in the most recent intraday candle, raising concerns about a potential bearish reversal.

NEBRA launches its zero-knowledge proof aggregator on Ethereum

Zero-knowledge proofs platform NEBRA has launched its Universal Proof Aggregation solution, bringing the benefits of ZKP verification to the crypto industry.

NEBRA UPA, which went live on Ethereum (ETH), is a protocol that combines zero-knowledge proofs into a single proof to offer cost-effective on-chain verification. The UPA protocol is designed to boost scaling and privacy across blockchains through proof aggregation, the NEBRA team said in a press release shared with crypto.news.

“Low throughput and the high cost of verification are major obstacles preventing applications from taking full advantage of ZKP technology. But with NEBRA UPA, ZKP is no longer a dream for the future – it is a solution that is available and being used right now,”

Shumo Chu, co-founder and chief executive officer of NEBRA.

A solution for zkEVMs and RaaS protocols

Protocols and projects that benefit from UPA’s solution include zero-knowledge virtual machines, co-processors, roll-up as a service solutions, and consumer applications.

An example of the latter is the WorldCoin (WLD) project, which taps into ZKP for its orb to verify a user is a unique human. The project’s World App uses this technology for identity proof without revealing information. Other notable projects in the ZKP ecosystem include Polygon zkVM, ZK Sync, and Starknet.

The issue of cost

ZKP costs can be prohibitive, but UPA looks to cut this from $20 to $2 for Ethereum and from $2 to $0.2 for layer-2 solutions. The significant reduction in the cost of a ZK proof for everyday crypto use cases, such as buying coffee, will empower developers and add to adoption across decentralized applications.

“Who wants to pay $20 for a ZK proof for a coffee purchase? But when the cost falls to mere cents, innumerable possibilities open up for developing decentralized applications,”

-Nebra co-founder Yi Tong.

NEBRA has raised a total of $4.5 million in funding from crypto venture capital firms, including Andreessen Horowitz, Bankless Ventures, and Nascent. The platform plans to deploy UPA v2 to top L2s to allow more dApps to tap into the benefits of reduced costs for on-chain ZKP use.

OSCE hosts crypto training for Armenian and Georgian investigators

The OSCE hosted a three-day training in Warsaw to enhance crypto investigation skills for Armenian and Georgian law enforcement.

In an Aug. 14 press release, the Organization for Security and Co-operation in Europe announced that it had conducted a specialized training session on “countering blockchain obfuscation techniques” in Warsaw, aimed at improving the investigative skills of law enforcement from Armenia and Georgia.

The OSCE said the course, hosted by Poland’s Ministry of Finance, marked the second such session facilitated by the organization, as part of a broader effort to combat illicit activities facilitated by cryptocurrencies.

“This course, delivered by a team of experts with substantial experience, has helped me acquire skills that I can apply directly in my work environment, making it very practically relevant.”

A participant from Georgia’s Financial Monitoring Service

The training addressed challenges in detecting and tracing crypto transactions that cybercriminals reportedly use to obscure their illicit activities. Participants were trained on advanced techniques used by bad actors to hide their digital footprints on-chain and explored methods for law enforcement to effectively counter these tactics, the press release reads.

The OSCE says the course was designed to equip investigators with the tools needed to navigate the complexities of blockchain technology in real-world scenarios. The course also “encouraged the investigators to exchange knowledge on trends, challenges and good practices from the different beneficiary countries.”

This initiative is part of the OSCE’s extra-budgetary project, supported by Germany, Italy, Poland, Romania, the U.K., and the U.S., which aims to combat money laundering and other financial crimes facilitated by virtual assets. In November 2023, the OSCE also hosted a similar training for Ukrainian authorities, aimed at improving their capacity to trace crypto transactions.

In a separate effort, the U.S. Internal Revenue Service announced in September 2023 that nearly 40 Ukrainian law enforcement officers completed advanced training on crypto tracing, utilizing blockchain analytics tools from CipherTrace and BlockTrace.

5ire launches hybrid layer-1 mainnet after 1m test transactions

Blockchain startup 5ire has rolled out its mainnet after a successful testnet phase, aiming to redefine blockchain’s environmental impact.

Layer-1 blockchain platform 5ire has launched its mainnet following a successful testnet phase, advancing its mission to drive environmentally sustainable blockchain development. In an Aug. 15 press release shared with crypto.news, 5ire stated that the launch comes after its testnet recorded over one million on-chain transactions in its first month.

The network claims it can process up to 1,500 transactions per second, returns 50% of gas fees to users, and features a sustainable Proof-of-Stake mechanism that rewards environmentally conscious practices.

The platform’s dual-chain architecture — compatible with Ethereum’s virtual machine — allows developers to create decentralized applications with a positive environmental impact, the press release reads.

“Our primary goal is to build a long-term, sustainable product with a proven track record.”

Pratik Gauri, 5ire co-founder

Ecologically friendly blockchain

The network leverages its native token, dubbed “5ire Coins,” to incentivize users to join 5ire as validators or nominators. While validators can earn rewards by verifying transactions and producing new blocks, nominators can earn rewards by selecting and backing validators with their staked 5ire Coins, according to the press release.

The firm claims that reward distribution is based on “adherence to the network’s protocol” and a commitment to sustainable practices, aligning with the U.N. Sustainable Development Goals. The project also boasts partnerships with various institutional clients, including the Government of India, which is integrating the platform into its school curriculum.

This launch follows 5ire’s $100 million Series A funding round two years ago, led by Sram and Mram, which elevated the startup’s valuation to $1.5 billion, making it one of the world’s first sustainable blockchain unicorns in India. The firm plans to use the funding to expand its operations across Asia, North America, and Europe.

Blockchain industry must break vendor lock-in for developers’ freedom | Opinion

No single entity, interest group, or political faction defines (or dominates) the blockchain industry. But despite all differences, positive and negative, there is a shared mission—achieving mass adoption. 

More people, businesses, and communities must benefit from crypto and blockchain tech worldwide. To achieve this fully, anyone should be able to build high-quality dApps and on-chain tools. Devs must have the freedom to express themselves in any language and on any chain. They should be able to build once and deploy anywhere. 

While the recent institutional uptake and political attention might seem exciting, they are mostly driven by vested interests. What’s ‘crypto-friendly now’ does not mean crypto-friendly five years from now, as Vitalik Buterin pointed out. Good dApps, however, are actual manifestations of blockchain’s principles and potential. Once deployed, they can continue serving the community on pre-defined terms enforced by censorship-resistant blockchains—ideally, even when the original creator is not there, as with Bitcoin (BTC). 

Thus, the endgame is empowering developers (and users). No single interest or agenda, political or technological, shall determine the path forward. In its purest form, crypto is an expression of freedom—freedom from intermediaries and censorship, freedom to express through code.

DApps make blockchain real—and valuable

Blockchain tech must solve real, day-to-day problems to transition from speculative adoption to long-term mass/retail adoption. However, the recent spike in financial nihilism and meme coin adoption shows that people care more about speculation than foundational principles. 

Yet speculation without actual underlying value is unsustainable. Only those apps and platforms that generate value through fees, transaction volumes, etc., will still be around in ten years or more. As of August 7, 2024, Uniswap, for example, collected about $13 million in weekly fees—that’s hundreds of millions in annual revenue. With the 10x price-to-earnings heuristic often applied to high-growth tech companies, it seems Uniswap (UNI) $4.5 billion valuation is on par, and the market is pricing it appropriately. 

DApps make crypto or blockchain tech usable for end-users. They bring the power of immutable code—which doesn’t need intermediaries—to the masses. Trading, lending, gaming, rideshares, etc., can all happen without any single entity opaquely and unfairly extracting value. 

Given crypto’s roots in Bitcoin and close proximity to money, finance was the first industry to be disrupted. But the recent rise of decentralized gaming, socials (DeSoc), physical infra (DePIN), AI, etc., on cost-effective and high-throughput chains like Base or Solana shows how the tech has a much wider scope than disrupting financial products/processes. 

That’s why there is a rising demand in the global dApp industry, where daily unique active wallet interactions reached an all-time high in Q2 2024. 

Industry unique active wallets | Source: DappRadar

Landline telephones took 99 years to reach peak adoption. Automobiles took 78. Computers, however, crossed 89% adoption in 24 years. Whereas social media and tablets achieved a similar feat in 14 and 7 years, respectively. 

This shows how newer technologies have achieved majority adoption in significantly less time than their predecessors. But key ‘enablers’ must be present for this, which dApps can be for blockchain tech. 

From user-friendly graphical interfaces to making backend components frictionless/invisible to end-users, dApps are inevitable. And those who say blockchain needs more dApps and less infra are quite right from this view. 

Anywhere, anytime, all at once

As crypto continues to grow, a lot of talented devs have entered the space, including some of the brightest minds from Google, Meta, IBM, etc., like the founding team at Aptos and Sui, among others. Great things have happened as a result. Move rising like a phoenix from Diem’s ashes and SVM from FTX are two prime examples of a new generation of devs picking alternatives to the EVM status quo. Lowering the barriers to dApp development is mission-critical now so more projects can emerge. 

For a long time, the Ethereum Virtual Machine has been the only standard available to blockchain developers. Along with Solidity, the EVM was built to deploy and run custom programs on Ethereum. Likewise, there is  ‘Solana VM’ on Solana, ‘Move VM’ on Aptos or Sui, Web Assembly on Cosmos, etc. Although these are great innovations with many merits, they have caused fragmentation and vendor lock-in. EVM-based dApps can’t run natively on Solana, and SVM-based dApps can’t use Ethereum, Binance Smart Chain, or other EVM-powered platforms.

Meanwhile, deploying dApps on multiple chains is very cumbersome and unfeasible due to high costs. For one, devs have to create and maintain multiple code bases. Thus, truly multi-chain and interoperable dApps take a lot of work to come by. Projects like AAVE or Pancakeswap are exceptions, as they have the necessary resources for multi-chain deployment. However, even for them, innovation in non-EVM code lags behind the EVM code due to high costs and time requirements. Moreover, for end-users, vendor lock-in means they need to use multiple wallets and hold assets from various ecosystems because their favorite dApp, wallet, or token doesn’t support the new chain they want to use. 

Devs want freedom from such walled gardens for the sake of blockchain’s long-term progress if not anything else. They must be able to build an application once and offer it to users across ecosystems, asset classes, and VMs—not just one. Users have a similar need.

Abstracting wallets, chains, and even VMs is a viable solution. It will let developers build dApps on any VM in any programming language and run them on every other chain or VM. That, too, with little or no additional costs and security compromises. 

Further, abstracting away the underlying complexities will allow anyone to build robust dApps with a few clicks. That will change everything. Web3 will mirror web2’s performance and speed after the mass market adoption of container technologies like Kubernetes, which helped get rid of public cloud vendor lock-in. To the extent that builders can utilize different chains/platforms for different aspects of their dApps based on specific needs and demands, such as Solana for high-frequency transactions, Ethereum for settlement finality and data availability, and so on. 

Solving vendor lock-in will improve the developer and end-user experience. Everyone can reap the benefits of the underlying tech stack and that’s the path to mass adoption. More dApps can enter the market than ever before. All of them won’t be great. But the more there are, the higher the chances of finding the next gamechanger.

Citigroup’s veteran departs to pursue career in crypto: report

Citigroup’s head of digital assets Shobhit Maini is leaving the bank to pursue an “entrepreneurial opportunity” in the crypto space.

Shobhit Maini, global head of digital assets in Citigroup’s market unit, has reportedly left the bank to focus on a career in the crypto industry, Reuters reports, citing an internal memo.

Maini, who joined the international banking giant, joined Citigroup in 2010, and led the bank’s digital assets efforts since 2021. Per Lee Smallwood, head of markets innovation and investments at the bank, Maini will “pursue an entrepreneurial opportunity in the digital asset space,” though the exact firm was not revealed.

Following Maini’s departure, Deepak Mehra, currently the international lead for Citi markets’ strategic investments, will assume leadership of the digital assets division within the markets unit, according to the memo.

Citigroup explores blockchain and tokenization

While Citigroup has not engaged directly in the cryptocurrency market, the bank has focused on exploring tokenization solutions and blockchain technology. For example, in 2023, Citigroup became the first digital custodian participant in the BondbloX Bond Exchange, a blockchain-based bond trading platform. The bank stored the underlying bonds issued and traded on the exchange as fractionalized assets.

Earlier, Citigroup collaborated with Wellington Management and WisdomTree to demonstrate the feasibility of issuing and managing tokenized private equity funds within a regulated framework, ensuring these digital assets are compatible with the bank’s existing systems.
