Cardano Tech Lead encloses the Bitcoin chain in a single block

The Technical Director of the Cardano Foundation, Matthias Benkort (also known as @KtorZ), has successfully encapsulated the entire Bitcoin blockchain into a single block on the Cardano blockchain. This announcementmade via X (formerly Twitter), has caused a stir in the blockchain community, highlighting the potential for advanced data management and interoperability between blockchains.

A turning point for Cardano and Blockchain technology

Benkort’s revelation came with the release of a new open source library on GitHub, titled “Merkle Patricia Forestry”. The library introduces a set of both on-chain and off-chain tools designed to work with Merkle Patricia Tries on Cardano. As described in the release documentation, a Merkle Patricia Trie is “a persistent, authenticated data structure for mapping arbitrary keys and values.” Essentially, it works as a highly efficient and secure hashmap.

The documentation elaborates on the structure, stating: “The elements are represented in a space-optimized trie (also known as a prefix tree) of root 16. The hash digest of their keys provides the path to the values ​​in the trie.” This approach offers numerous use cases, such as maintaining large on-chain ledgers (e.g., domains), or providing large oracle datasets of intrinsic data (e.g., a delegating/delegating map) or data extrinsic (for example, GitHub data about an ecosystem of projects). It is best suited for long-lived datasets that grow at a slow rate, such as a Blockchain Proof of Work (PoW)..

Key features of the Merkle Patricia Forestry library include rapid enrollment, insertion, and deletion of any key/value element in a large store, facilitated by a root hash digest (32 bytes) and a concise proof ( <1KB). The library incorporates several optimizations inspired by Ethereum's Modified Merkle Patricia Trie (MPT), but introduces a new approach to organizing nodes as small Sparse Merkle Trees. This innovation results in much smaller proof sizes and forms the basis for the library's name: Merkle Patricia Forestry.

Benkort explained the performance tradeoffs, pointing out that the optimization sacrifices some memory and CPU execution units to achieve smaller test sizes. Despite this, the library strikes a good balance between test size, memory usage, and CPU efficiency, as detailed in the performance tables included in the documentation. These tables summarize the trial sizes, memory units, and CPU units required for various trial sizes, highlighting the efficiency of the library in different scenarios.

Detailed explanation and demonstration

In a series of detailed posts on X, Cardano Foundation’s Benkort provided further insights into the library’s implementation and capabilities. He explained that the library consists of two parts: one implemented in Aiken for smart contract-specific utilities and another in Node.js for off-chain operations. This complete implementation of the modified Merkle Patricia Tries, with a unique twist, is what Benkort calls “Merkle Patricia Forestry”.

“Basically, this is an authenticated data structure for mapping arbitrary keys to arbitrary values,” Benkort said. “However, it is made in such a way that it is possible to perform some operations just from a small hash and a concise proof, without the need to transport the entire data structure.”

For those familiar with blockchain technology, Merkle Trees are a similar, albeit simpler, structure used primarily to represent lists of items and verify their membership using a root hash. However, Merkle Patricia Tries (MPT) extend this functionality, allowing not only membership verification but also insertion and deletion of key/value pairs. Ethereum uses MPT for blockchain state and transaction storage, allowing light clients to query balances without storing the entire blockchain.

A significant problem with traditional MPTs is the large size of the evidence, which can span multiple kilobytes for large data stores. This isn’t as problematic for off-chain operations, but on-chain every byte is precious. Benkort’s implementation solves this problem by using tiny, sparse Merkle trees of 16 elements at each level, effectively creating trees within trials. This framework drastically reduces the size of proofs, trading some computational steps for Cardano’s efficiency gains.

Benkort demonstrated this ability through a recent transaction he spent on UTxO containing the root hash of a Merkle Patricia Forestry representing the entire Bitcoin block header hash, compressed into just 32 bytes. The transaction demonstrated the ability to continue the chain by inserting a new block into the trie, maintaining an authenticated chain of over 850,000 blocks with minimal data overhead.

“The transaction I just linked is doing something quite unexpected,” Benkort explained. “It passes a UTxO that contains the root hash of a Merkle Patricia Forestry that represents the entire Bitcoin block header hash, mapped to their transactions. That’s approximately 850,000 blocks, compressed into 32 bytes.”

To spend this UTxO you need to provide on-chain proof to show the continuation of the chain by inserting a new block into the trie. The updated root hash stored on the chain must represent the previous chain plus one block. The entire validator for this operation fits into just 26 lines of Cardano Aiken.

Future implications and use cases

Benkort highlighted the potential applications of this technology, ranging from trustless bridges to arbitrarily large key/value stores managed completely on-chain. “Imagine the realm of possibilities with such large data sets,” she suggested. “A domain registry? A data feed on financial markets? GitHub Stats? I see a world where institutions or committees publish large data sets in the form of a simple on-chain root hash, effectively acting as oracles for a variety of smart contracts along the line.”

Benkort concluded by reflecting on the journey of this project, which began as a parallel project at the end of last year. “It feels good to finally release it,” he said. “It was originally something I started at the end of last year, kind of as a side project. Given the many conversations about it lately, I thought I’d resurrect and package that code properly. Open source for the win.”

At the time of writing, Cardano (ADA) was trading at $0.455.

Online Broker Futu Offers Cryptocurrency Trading in Hong Kong, With Nvidia and Alibaba Stock as Rewards

Futu Securities International, Hong Kong’s largest online broker, has launched retail cryptocurrency trading in the city, offering shares of Alibaba Holding Group AND Nvidia as a reward in an attempt to attract investors. Futu has begun allowing Hong Kong residents to trade Bitcoin and ether, the world’s two largest cryptocurrencies, directly on the brokerage platform using Hong Kong or U.S. dollars, the company announced Thursday.

The online retail broker said last month that it had received an upgrade to its securities license from the Securities and Futures Commission (SFC), allowing Futu to offer virtual asset trading services to both professional and retail clients in the city.

Futu’s move comes as Hong Kong seeks to boost its attractiveness as a business hub for virtual assets, with the city government launching a series of new cryptocurrency policy initiatives over the past two years, including a mandatory licensing regime for cryptocurrency exchanges.

In addition to offering cryptocurrency trading on its flagship brokerage app, Futu is also seeking a cryptocurrency trading license for its new PantherTrade platform. That platform is among 11 in Hong Kong that are currently “deemed licensed” for cryptocurrency trading, an arrangement that allows them to operate in the city while they await full approval from the SFC.

Hong Kong’s progress in becoming a crypto hub has encountered various challenges, including exit of the major global platforms and relatively low trading activity for cryptocurrency exchange-traded funds offered on local stock exchanges.

Futu is now offering a series of incentives to potential investors, amid a cryptocurrency bull market that has seen the price of bitcoin rise 45 percent this year.

Hong Kong investors who open accounts in August and deposit HK$10,000 (US$1,280) over the next 60 days can receive HK$600 worth of bitcoin, a HK$400 supermarket voucher or a single Chinese stock. e-commerce giant Alibaba. Alibaba owns the South China Morning Post.

By holding 80,000 U.S. dollars for the same period, users can get 1,000 Hong Kong dollars in bitcoin or a share of U.S. artificial intelligence (AI) chip maker Nvidia, whose shares have risen more than 140 percent this year.

A Futu representative said the brokerage firm will also waive cryptocurrency trading fees starting Thursday until further notice.

Futu is the first online brokerage in Hong Kong to allow retail investors to buy cryptocurrency directly on its platform. SFC rules require it to offer this service through a tie-up with a licensed cryptocurrency exchange. Futu is partnering with HashKey Exchange, one of only two licensed exchanges in Hong Kong, according to the representative.

Futu’s local rival Tiger Brokers also said in May that it had begun offering cryptocurrency trading services to professional investors on its platform following a license update. The SFC defines professional investors as those with more than HK$8 million in their investment portfolios or corporate entities with assets exceeding HK$40 million.

Tech Crash: $2.6 Trillion Market Cap Vanishes as ‘Magnificent 7’ Prices Stumble

A group of seven megacap tech stocks, often called the Magnificent 7, have lost more than $2.6 trillion in value over the past 20 days, or an average of $125 billion per day over the period. In total, these stocks have lost “three times the value of the entire Brazilian stock market.”

This according to the economic news agency Letter from Kobeissiwho noted on the microblogging platform X (formerly known as Twitter) that the Magnificent 7 batch “is worth as much as Nvidia’s entire current market cap in 20 days,” with Nvidia itself having lost $1 trillion from its high.

The group, which includes Nvidia, Microsoft, Amazon, Apple, Alphabet, Meta and Tesla, has undergone a significant correction: in the last 20 days Nvidia has lost 23% of its value, or about $800 billion, while Tesla has fallen 19%, losing $164 billion.

Microsoft, Apple, Amazon, Alphabet and Meta all posted losses of between 9% and 15%, losing between $257 billion and $554 billion in market capitalization, wiping out a total of $200 billion more “than every single German stock market tock combined.”

Tech titans, which have outperformed the broader S&P 500 index since the market bottom of 2022, are now facing a reckoning as investors grow increasingly wary about the sustainability of their meteoric rise, with Nvidia taking the lead soaring 110% since the beginning of the year and over 2,300% in the last five years.

Earnings reports from these companies, starting with Microsoft and culminating with Nvidia in late August, will be closely watched for signs of weakness. Their performance could set the tone for broader market sentiment, with implications for everything from cryptocurrency to other high-risk assets.

Their poor performance comes after a leading macroeconomist, Henrik Zeberg, reiterated his forecast of an impending recession that will be preceded by a final wave in key sectors of the market, but which can potentially be the worst the market has seen since 1929the worst bear market in Wall Street history.

In particular, the Hindenburg Omen, a technical indicator designed to identify potential stock market crashes, began flashing just a month after its previous signal, raising concerns about a possible impending stock market downturn.

The indicator compares the percentage of stocks hitting new 52-week highs and lows to a specific threshold. When the number of stocks hitting both extremes exceeds a certain level, the indicator is said to be triggered, suggesting a greater risk of a crash.

A large conference hall filled with enthusiastic attendees, Bitcoin logos prominently displayed, and a podium with an American flag

To the Bitcoin Conference 2024 In Nashville, Tennessee, former President Donald Trump delivered a keynote speech.

Trump, the Republican presidential candidate, used the platform to appeal to the tech community and solicit donations for the campaign. During the conference, He said:

I promise the Bitcoin community that the day I take the oath of office, Joe Biden and Kamala Harris’ anti-crypto crusade will be over… If we don’t embrace cryptocurrency and Bitcoin technology, China will, other countries will. They will dominate, and we can’t let China dominate. They are making too much progress as it is.

Trump’s speech focused heavily on cryptocurrency policy, positioning it as a partisan issue. He said that if reelected, he would fire SEC Chairman Gary Gensler on his first day in office, a statement that drew enthusiastic applause from the audience. This statement marked a stark contrast to Gensler’s tenure, which has been characterized by rigorous oversight of the cryptocurrency industry.

The former president outlined several pro-crypto initiatives he would undertake if elected. These include transforming the United States into a global cryptocurrency hub, keeping all government-held Bitcoin as a “national Bitcoin reserve,” establishing a presidential advisory council on Bitcoin and cryptocurrency, and developing power plants to support cryptocurrency mining, emphasizing the use of fossil fuels.

Trump’s current embrace of cryptocurrencies represents a reversal from his stance in 2021, when described Bitcoin as a “scam against the dollar.” He also noted that his campaign has received $25 million in donations since accepting cryptocurrency payments two months ago.

The event featured other political figures, including Republican Senators Tim Scott and Tommy Tuberville, as well as Democratic Representatives Wiley Nickel and Ro Khanna. Independent presidential candidate Robert F. Kennedy Jr. also spoke at the conference.

Trump’s appearance at Bitcoin 2024 reflects growing support for his campaign from some tech leaders, including Tesla CEO Elon Musk and cryptocurrency entrepreneurs Cameron and Tyler Winklevoss.

While Trump has described the current administration as “anti-crypto,” Democratic Congressman Wiley Nickel said Vice President Kamala Harris is taking a “forward-thinking approach to digital assets and blockchain technology.”

This event underscores the growing political importance of cryptocurrency policy in the upcoming presidential election.

Kamala Harris and Democrats Respond on Cryptocurrencies

In a strategic move to repair strained relations, Vice President Kamala Harris’ team has initiated a dialogue with major cryptocurrency industry players. This outreach aims to restore the Democratic Party’s stance on digital assets and promote a more collaborative approach.

THE Financial Times reports that Harris’s advisors have reached out to representatives from industry leaders like Coinbase, Circle, and Ripple Labs. This move comes as the cryptocurrency community increasingly supports Republican candidate Donald Trump, reflecting growing dissatisfaction with the current administration’s cryptocurrency policies.

THE disclosure follows a letter from Democratic lawmakers and 2024 candidates urging the party to reevaluate its approach to digital assets. Harris’s team stresses that this effort is less about securing campaign contributions and more about engaging in constructive dialogue to develop sensible regulations.

The move is part of a broader strategy to reshape the Democratic Party’s image among business leaders, countering perceptions of an anti-business stance. Harris’ campaign aims to project a “pro-business, responsible business” message.
