Merkle trees vs. Verkle trees, Explained
Merkle trees are employed in Bitcoin (BTC) and other cryptocurrencies to more effectively and securely encrypt blockchain data. Verkle trees allow for smaller proof sizes, particularly important for Ethereum’s upcoming scaling upgrades. But, how do you identify a Merkle tree? Leaf nodes, non-leaf nodes and the Merkle root are the three essential parts of a Merkle tree in the context of blockchains. Transaction hashes or transaction IDs (TXIDs) reside in leaf nodes, which can be viewed on a block explorer. Then, above the leaf nodes, a layer of non-leaf nodes is hashed together in pairs. Non-leaf nodes keep the hash of the two leaf nodes they represent below them. Related: What is blockchain technology? How does it work? As the tree narrows as it ascends, half as many nodes ...
FTX revenue reportedly grew 1000% in one year, leaked documents reveal
FTX was among the many crypto exchanges with a front-row seat to witness the crypto hype of 2021, back when Bitcoin (BTC) and other cryptocurrencies hit their all-time highs. Driven by massive customer onboarding, partnerships, sponsorships and other factors, FTX’s revenue reportedly grew 1000% in 2021 — revealed internal documents. Audited financials of FY 2020-2021 show FTX witnessing a 1000% increase in revenue — growing from $90 million in 2020 to $1.2 billion in 2021, claimed CNBC alleging access to the documents. The revenue breakdown discloses a 1842.85% increase in operating income for FTX, from $14 million to $272 million in one year. The crypto exchange amassed $388 million in net income, a 2182.35% increase from last year’s $17 million. FTX has reportedly made $270 million in th...
Can Web3 be hacked? Is the decentralized internet safer?
Web3 came into existence posed as a blockchain-powered disruption to the current state of the internet. Yet, as a nascent technology, a fog of assumptions plagues discussions about the real capabilities of Web3 and its role in our day-to-day lives. Considering the promise of a decentralized internet using public blockchains, a complete transition to Web3 would require scrutiny across several factors. Out of the lot, security stands as one of the most crucial features as, in a Web3-powered world, tools and applications hosted over the blockchains go mainstream. Smart contract vulnerabilities While the blockchains that host Web3 applications remain impenetrable from being hostage to attackers, hackers target the vulnerabilities within the project’s smart contracts. Smart contract attacks on ...
Ethereum Merge prompts miners and mining pools to make a choice
The Ethereum blockchain is all set to make its highly anticipated transition from its current proof-of-work (PoW) mining consensus to proof-of-stake (PoS). The Merge date is officially scheduled for Sept. 15–16 after the successful final Goerli testnet integration to the Beacon Chain on Aug. 11. At present, miners can create new Ether (ETH) by pledging a huge amount of computing power. After the Merge, however, network participants, known as validators, will be required to instead pledge large amounts of pre-existing ETH to validate blocks, creating more ETH and earning staking rewards. The three-phase transition process began on Dec. 1, 2020, with the launch of the Beacon Chain. Phase 0 of the process marked the beginning of the PoS transition, where validators started staking their ETH f...
What is an NFT and why are they so popular?
Nonfungible tokens (NFTs) have been part and parcel of the cryptocurrency space for the last couple of years. Still, their value and utility across several industries have driven their proliferation into mainstream consciousness. Cointelegraph’s director of video production Jackson DuMont delves into the intricacies of NFTs, highlighting the importance of the underlying blockchain technology in proving ownership of digitally scarce assets: “NFTs provide unique, verifiable and immutable proof of ownership of digital goods. True digital ownership of assets through NFTs is a revolutionary idea that will transform how we interact with the internet.” Another important aspect of NFT technology highlighted by DuMont is handing the ownership of digital assets to users as Web3 functionality begins ...

DeFi needs to start creating real-world value if it wants to survive
The total value locked in decentralized finance (DeFi) projects is hovering around $62 billion as of mid-August, down from a peak of over $250 billion in December 2021. Capital is fleeing the crypto space amid war, soaring inflation and whatever other surprises 2022 may still have in store for us. However, unlike previous crypto bull runs, it was not just retail interest that drew in this capital in the first place. Rather, major institutional players, which have recently opened up to crypto, quickly developed an appetite for the yields DeFi is known for. But now that winter is upon us, the pitfalls of high-yield platforms have become more apparent. Value can’t come out of thin air In some sense, value is always somewhat subjective, defined by one’s personal considerations and goals. A pho...
Are non-KYC crypto exchanges as safe as their KYC-compliant peers?
Many see implementing Know Your Customer (KYC) tools in crypto as a deterrent to the Bitcoin (BTC) Standard, which has predominantly promoted anonymized peer-to-peer transactions. However, regulators stay put on promoting KYC and anti-money laundering (AML) implementations as a means to ensure investors’ safety and protection against financial fraud. While most crypto exchanges have begun implementing regulatory recommendations to remain at the forefront of crypto’s mainstream adoption, investors still have the choice to opt for crypto exchanges that promote greater anonymity by not imposing KYC processes. But does opting for the latter as an investor mean compromising on safety? A matter of trust Anonymity goes both ways in most cases. Owners of crypto exchanges running non-KYC (or ...
Who accepts Ethereum as payment?
Taking payment in Ethereum brings in a gamut of advantages for both users and entrepreneurs. Transitioning to a blockchain-based ecosystem brings in a string of advantages for users as well as entrepreneurs. Here is a drop-down detailing why accepting payment in Ethereum works well for the customers of an enterprise: Additional payment option In a world that is fast adopting cryptocurrencies, providing customers with an additional payment option gives businesses an advantage over their competitors. Cryptocurrency gateways enable merchants to accept digital payments and receive the amount in fiat. Transparency A decentralized ecosystem is inherently transparent, giving customers more confidence while making the purchase. Crypto transactions get executed on a blockchain where they are writte...
Web3 games incorporate features to drive female participation
Although there is still an apparent lack of women in the Web3 sector, blockchain-based games geared toward women may help drive inclusivity. A recent report from the Entertainment Software Association found that 48% of gamers in the United States identify as female. It has also been noted that nearly half of all gamers in the world are women. The interest that women have taken in the billion-dollar gaming sector is notable. This, combined with the massive growth being projected by the GameFi industry, is a key reason why a number of Web3 games are being built specifically for female users. Beryl Chavez Li, co-founder of Yield Guild Games — a global play-to-earn gaming community — told Cointelegraph that she believes blockchain-based games like Axie Infinity have started to see an upt...
3 reasons why the Bitcoin price bottom is not in
Bitcoin (BTC) recovered modestly on Aug. 20 but remained on course to log its worst weekly performance in the last two months. Bitcoin hash ribbons flash bottom signal On the daily chart, BTC’s price climbed 2.58% to $21,372 per token but was still down by nearly 14.5% week-to-date, its worst weekly returns since mid August. Nonetheless, some on-chain indicators suggest that Bitcoin’s correction phase could be coming to an end. That includes Hash Ribbons, a metric that tracks Bitcoin’s hash rate to determine whether miners are in accumulation or capitulation mode. As of Aug. 20, the metric is showing that the miners’ capitulation is over for the first time since August 2021, which could result in the price momentum switching from negative to positive. Bitcoin Hash R...
Newest cause for climate optimism? The U.S. rivalry with China
It also spurred hopes that U.S. economic competition might succeed where the diplomacy of Biden’s climate envoy John Kerry has largely failed — by extracting new commitments from Beijing to reduce China’s greenhouse gas output. “What this does is show to the Chinese that the U.S. is actually going to be real in this game and not actually just going to talk about it, and I think that’s a benefit to everyone,” said Jake Schmidt, senior strategic director of international climate with the Natural Resources Defense Council, an environmental research and advocacy group. “The planet will benefit from that healthy competition.” The IRA was signed less than two weeks after Beijing suspended its cooperation with the U.S. on climate change — a dialogue that had been fostered by Kerry and viewed as a...
