The mechanics of lightning nodes: An in-depth look – The Jerusalem Post
If you're someone who's interested in cryptocurrencies, there's a good chance you've come across the term "lightning nodes" before. However you might not have a clear understanding of how they function. Allow us to delve into the workings of lightning nodes within the Lightning Network, and how they facilitate rapid transactions. The aptly named lightning nodes ensure that you can trade swiftly and seize every opportunity without delay.
To start, the definition of a lightning node is a software implementation of the open-source lightning protocol that enables participants to use the lightning network. This decentralized payment system and layer 2 scaling solution was built on the Bitcoin blockchain. The network is here to help users looking to take advantage of a faster, more affordable, and more scalable network than ever before, increasing the efficiency and effectiveness of every transaction.
When you use the lightning network, which operates on lightning nodes, you no longer have to wait for the confirmation of each transaction on the Bitcoin blockchain. With less resistance in your way, you can navigate the crypto market on your own terms.
So, how does it work? Well, the lightning network is composed of nodes with channels that link them together. When you open a channel, it connects your node to another lightning node. The node can send or receive payments through its channel with any node directly or indirectly linked to it. This ability derives from lightning nodes being able to securely route payments through the network.
With lightning nodes in place, payments will either reach their intended destination or fail completely with no in-between. This type of security can allow you to make moves confidently in a worry-free environment.
Lightning nodes determine the best route for sending payments, taking certain essential factors into account. These include channel capacities and fees charged by different nodes along possible routes. So, your transactions are always conducted with the most efficacy available at the time.
If you're interested in joining the lightning network, all you need to do is set up a lightning nod by establishing a connection with at least one other node. To get started, install the lightning protocol software on your computer and configure it to connect with the network. This typically involves creating a key and opening payment channels with other nodes on the lightning network. Before you know it you'll be ready to go with the fastest way to conduct transactions. You can begin sending and receiving payments by having the recipient initiate a payment request or invoice from their node. Once the payment is sent, the recipient's node will confirm it by sending back an acknowledgment to the sender.
Lightning nodes operate with a cryptographic technique called onion routing, so your identity is always protected, and every transaction is private and secure. It also works with smart contracts, so you can automatically perform functions by setting parameters beforehand.
You can handle a high volume of transactions in record time with the help of lightning nodes. Get started with real-time, low-cost payments in a natively online, programmable environment today.

Patent: IOTA Tangle Tech Can Play Crucial role In NFT Betting – Crypto News Flash
Non-fungible tokens (NFTs) have made major inroads in the market offering a very wide range of utility across different industry sectors. One such industry where NFTs are gaining prominence is the betting industry. One of the major lacunas for the betting industry is a lack of trust and transparency. Using blockchain-based NFTs can help in filling these gaps.
A new patent talks about betting with NFTs while using IOTAs Tangletech. The innovation pertains to a computerized system designed to utilize supplied data records related to betting for secure manipulation and privacy-preserving facilitation of bets among both known and unknown users. This is achieved through the utilization of a distributed, decentralized database.
Betting systems aka betting platforms operate on the premise that a betting provider offers various bets and outlines their details. Drawbacks of this betting approach include the charges imposed by the betting agent and the inflexible betting conditions mandated by the betting provider.
Decentralized betting platforms address these issues but give rise to additional challenges due to the inherent blockchain architecture. The Ethereum blockchains current capacity is limited to approximately 15 transactions per second, severely constraining its scalability. Consequently, activities such as live betting that demand swift participation become impractical. Furthermore, the blockchains transaction fees hinder the viable resolution of bets with stakes lower than the fees themselves, as such fees would outweigh potential betting gains.
The present invention seeks to overcome these aforementioned challenges by establishing a decentralized betting platform that ensures scalability and allows users to freely determine fees for executing essential Smart Contracts (SC).
Follow us for the latest crypto news!
IOTAs architecture comprises two tiers: the base layer (L1) is the Tangle, a toll-free data structure formed by connections between transactions across nodes. Unlike traditional blockchains with one-directional growth, the Tangle allows growth in any direction, enhancing transaction throughput. Each new transaction verifies up to seven parent transactions its attached to.
Multiple nodes with consensus will later verify smart contracts like transactions. IOTAs architecture also adds a second layer (L2) to address challenges in managing smart contracts on the Tangle. L2 features unidirectional blockchains ensuring a global objective state. Smart contracts execute on Wasp Nodes, forming committees to find consensus, and L2 blockchain status is synchronized with an L1 account.
IOTAs multi-asset ledger extends the Tangle into various tokens or assets within L1, including custom currencies and NFTs. This is distinct from single-currency blockchain counterparts. NFTs are a unique output type, providing owners full control over trade and deletion. The NFT assets will consist of the following parts.
The IOTA architecture, designed as a DAG with parallel layers, effectively addresses the scalability and fee structure challenges. This innovation also offers a scalable system with the added advantage of fee-free smart contracts.

Upgrading Web3 User Experience With Account Abstraction – Forbes
was one of the most prominent abstract painters, renowned for his iconic color field paintings, which featured captivating irregular rectangles of color.AFP via Getty Images
A traditional EthereumETH wallet is called an Externally Owned Account (EOA) and it is what you use with MetaMask for example. As a result, your Ethereum account is uniquely derived from the cryptographic key pair that signs on its behalf.
Account Abstraction (AA) is the process of separating signing keys from the accounts for which they sign. Developers can use this separation to shape their UX and abstract technical details from the user by abstracting accounts from the signing keys.
The path to mainstream adoption requires a significant user-friendliness leap, and this is where AA steps in, aiming to streamline the user experience for decentralized applications (dApps), eliminating the complexities that often deter newcomers.
There have been several attempts at implementing AA in the past, such as EIP-86 and EIP-2938, but these required consensus layer changes ("hard forks") which made them impractical to implement. However, the ERC-4337 standard offers a new approach that doesn't require consensus layer changes, allowing developers to start building today.
"In traditional blockchain systems, most users have an EOA as their default account, which is inherently intertwined with their private key. EOAs require a good understanding of how a blockchain works to be used safely, which hinders mainstream adoption," told me in an interview Tom Teman, AA Product Manager at Ethereum Foundation. "AA allows users to use smart contracts as their accounts, providing a better user experience. They decouple the account from the private keys, which allows the use of arbitrary verification logic, such as multi-sig verification, and enable sponsored transactions, where users can pay transaction fees in ERC-20 tokens or have them sponsored by any third party. They also provide enhanced security features, such as various account recovery methods and time-locks, and enable atomic multi-operations, which allow users to complete multiple operations with a single transaction".
Friend.tech, a pioneering social network in the Web3 space, is a prime example of how AA can simplify onboarding. Instead of requiring users to navigate wallet integration, friend.tech employs a novel authentication method. Users can authenticate via SMS, GoogleGOOG, or AppleAAPL, providing a familiar sign-in process. Behind the scenes, AA is at work, creating a self-custodial embedded wallet for each user. The recent effort of ERC-4337 to standardize an Ethereum model for creating on-chain accounts with a flexible signing system have enabled Privy, friend.tech's Web3 onboarding partner in this endeavor, to provide seamless wallet onboarding experiences using AA. This approach also emphasizes user data privacy - neither friend.tech nor Privy have access to users' private keys, which ensures users' crypto asset holdings remain secure, while still granting them full control and accessibility.
Friends.tech bridges the gap between blockchain users and mainstream users by focusing on a smooth onboarding process, and their numbers speak for themselves - according to their Twitter account, they have about 20,000 active daily users, with 75% returning after the second day, and 50% returning for the full week, and with an average daily active user using the dApp for 30 minutes.
On top of AA, the ability to use native tokens to pay transaction fees within the Web3 ecosystem is a pivotal development that enhances user experiences. Visa's approach, known as paymasters, is one compelling example of this. By using fiat money linked to their Visa cards, users can cover their on-chain gas fees using Ethereum's ERC-4337 standard. In this approach, a paymaster contract is a specialized smart contract account that sponsors gas fees for Contract Accounts, which are viewed as user-centric smart contracts. As a result of this solution, users do not need to possess native blockchain tokens or navigate token bridge processes just to cover gas fees.
For instance, envision Alex, a self-custodial wallet user, who wishes to participate in a DeFi project involving the minting of new tokens. With the proposed Visa Paymasters solution, Alex seamlessly utilizes her Visa card to cover gas fees. This process streamlines user interactions, allowing Alex to effortlessly select her Visa card as the means to cover gas fees, while the complex backend processes are taken care of by the Visa system.
Friend.tech and Visa are great examples of how AA can enable mainstream adoption, combining user-centered design with novel payment methods, ultimately improving blockchain transaction accessibility and usability.

Exploring the World of Crypto Loans: Benefits, Risks, and Future … – cryptonewsbytes.com
Introduction
The world of finance has undergone a significant transformation with the emergence of cryptocurrencies. Among the innovative applications of cryptocurrencies is the concept of crypto loans. These loans provide a bridge between the traditional financial system and the crypto ecosystem, offering users the ability to leverage their digital assets for various purposes. This article aims to provide a comprehensive overview of crypto loans, including their definition, functioning, benefits, risks, types, selection of providers, acquisition process, use cases, and future trends.
Crypto loans, also known as blockchain-based loans, are financial products that allow cryptocurrency holders to borrow funds by using their digital assets as collateral. Unlike traditional loans, crypto loans operate within the realm of decentralized finance (DeFi), leveraging smart contracts to automate the lending and borrowing process.
The process of obtaining a crypto loan involves a borrower depositing a certain amount of cryptocurrency as collateral into a smart contract. In return, they receive a loan in a stable coin or another cryptocurrency. The collateral remains locked in the smart contract until the borrower repays the loan with interest. Failure to repay could result in the lender liquidating the collateral to recover the funds.
Crypto loans offer a wide range of collateral options, allowing borrowers to access funds without selling their assets. This enables them to retain potential long-term value appreciation.
One of the most significant advantages of crypto loans is that they are often available without the need for traditional credit checks. Borrowers creditworthiness is determined by the value of their collateral, making these loans accessible to a broader range of individuals.
By not selling their cryptocurrency, borrowers can avoid triggering capital gains taxes. This is particularly advantageous for those seeking liquidity while minimizing tax liabilities.
The inherent volatility of cryptocurrencies poses a risk to both borrowers and lenders. If the collaterals value significantly drops, borrowers might face margin calls or even liquidation.
In cases of extreme price volatility, lenders might issue margin calls, requiring borrowers to either repay a portion of the loan or provide additional collateral. Failure to do so could lead to the liquidation of the collateral.
Collateralized loans are the most common type of crypto loans. Borrowers provide collateral and receive a loan in return. These loans have a lower risk for lenders due to the collateral, resulting in relatively lower interest rates.
Unsecured crypto loans do not require collateral, relying instead on the borrowers creditworthiness. However, these loans come with higher interest rates to compensate for the increased risk taken on by the lender.
Prospective borrowers should thoroughly compare interest rates and loan terms offered by different providers to ensure they are getting the best deal.
Selecting a reputable and secure crypto loan provider is crucial. Reading reviews, checking for any past security breaches, and assessing the platforms overall reputation can help make an informed choice.
Begin by researching and comparing various crypto loan providers to find one that aligns with your needs.
Submit an application to your chosen lender and follow their instructions for collateral locking. Once approved, the loan amount will be disbursed.
Ensure timely repayment of the loan according to the agreed-upon terms. Upon repayment, the locked collateral will be released from the smart contract.
Crypto loans allow investors to access funds without selling their valuable cryptocurrency holdings, thus maintaining exposure to potential price gains.
Crypto loans can be used strategically to manage tax liabilities. Borrowers can secure liquidity without triggering taxable events that result from selling their crypto assets.
As cryptocurrencies gain wider acceptance, the integration of crypto loans into traditional financial systems is a likely development, bridging the gap between the two worlds.
The evolving regulatory landscape will significantly impact the future of crypto loans. Striking a balance between innovation and compliance will be a crucial factor in shaping the sectors growth.
Crypto loans have introduced a novel way for cryptocurrency holders to leverage their assets while retaining ownership. With benefits such as flexible collateral options, accessibility, and tax efficiency, they have gained traction in the financial world. However, the risks associated with price volatility and liquidation cannot be overlooked. As the crypto space continues to evolve, crypto loans are poised to play a pivotal role in reshaping the lending and borrowing landscape, providing innovative solutions for individuals seeking financial flexibility within the crypto ecosystem.

What are Peer-to-Peer Transactions? – Blockchain Council
Security and Trust in Peer-to-Peer TransactionsDecentralizations Impact on Security
In the realm of peer-to-peer (P2P) transactions, security stands as a paramount concern. The very essence of P2P lies in its decentralized nature, where transactions occur directly between parties without intermediaries. This decentralization has profound implications for security. Traditional centralized systems carry a single point of failure risk, making them vulnerable to attacks. In contrast, P2P transactions distribute authority across the network, reducing the vulnerability to a single breach.
The absence of a central authority, however, requires robust security mechanisms at every node. Pioneering cryptographic techniques play a pivotal role in ensuring confidentiality, integrity, and authenticity. From the perspective of security, the decentralized nature of P2P transactions introduces a new paradigm, demanding continuous vigilance against evolving threats.
Cryptography emerges as the bedrock of trust in P2P transactions. It transforms sensitive information into an unreadable format during transmission, safeguarding it from prying eyes. Public and private keys form the cornerstone of cryptographic protocols. Public keys, openly shared, allow anyone to encrypt information, while private keys, kept confidential, enable decryption.
Cryptocurrencies, a prominent application of P2P transactions, rely on Blockchain technology, where cryptography secures transactions, prevents double-spending, and ensures immutability. Blockchains distributed ledger records each transaction across the network, with cryptographic hashing further enhancing security. This cryptographic synergy engenders trust in P2P transactions, making them tamper-resistant and auditable.

Ethereum sharding emerges as a potential remedy for the scalability challenge confronting the Ethereum blockchain. The concept involves fragmenting the blockchain network into smaller, manageable segments termed shards. Each shard functions as an independent blockchain network, complete with its validators and transactions.
Presently, the Ethereum network operates as a unified blockchain, where each node processes and validates all transactions. However, with escalating users and transactions, network efficiency diminishes, leading to sluggishness and higher costs. Sharding introduces horizontal scalability by introducing additional shards, each equipped to manage a distinct transaction subset.
Understanding sharding is akin to the analogy of a movie theater queue. A single-ticket seller causes delays, whereas multiple ticket counters speed up the queue, yielding shorter wait times for customers. Similarly, sharding empowers Ethereum to process transactions more efficiently and respond to increasing demands.
In the realm of blockchain technology, sharding is a transformative concept. It involves fragmenting a blockchain into smaller, interconnected units known as shards. Each shard becomes a self-contained entity, capable of processing transactions and executing smart contracts independently.
Shardings essence lies in its ability to parallelize tasks. By distributing the workload across multiple shards, the network gains the power to process transactions in parallel, leading to enhanced efficiency and throughput. In essence, sharding breaks the chains of limitation, enabling blockchain systems to scale seamlessly and tackle the challenges of burgeoning user demands.
Sharding isnt just a minor tweak; its a paradigm shift in how blockchains operate. By compartmentalizing the data and distributing it across shards, blockchain networks gain the ability to process transactions concurrently. This evolution in transaction processing translates to a network that can handle an unprecedented volume of transactions, all executed in parallel.
The impact is tangible: a more scalable and responsive blockchain ecosystem. Slow confirmation times and high fees become issues of the past as shards collectively process transactions with remarkable efficiency. Ethereums journey to sharding paints a future where blockchain technology can truly realize its potential, offering a decentralized, efficient, and user-friendly platform for a multitude of applications.
To grasp the concept of sharding, its essential to understand how nodes operate within a blockchain network. Nodes are essentially the computers that store and propagate transactional data, playing a crucial role in maintaining the networks functionality.
In Ethereums current proof-of-work (PoW) consensus mechanism, every single transaction on the network is processed by all nodes. However, as transaction volumes grow, scalability issues arise due to the increasing load on the network.
Sharding addresses this challenge by segmenting nodes into clusters known as shard chains. Each shard chain assumes responsibility for processing a specific subset of transactions. These shard chains collaborate to achieve consensus and verify blocks of transactional data.
In the Ethereum context, sharding will introduce shard blobs, a term referring to interconnected databases, instead of traditional shard chains. This innovation is driven by danksharding, a novel sharding approach. Ethereums sharded architecture will comprise 64 linked databases. Transactions will occur simultaneously and in parallel across shards, enhancing efficiency.
Each shard will incorporate a committee of 128 validators tasked with proposing and validating blocks every 12 seconds. This streamlined approach promises to revolutionize Ethereums scalability and transaction processing dynamics, paving the way for a more responsive and efficient blockchain ecosystem.
Sharding in Ethereum collaborates with layer-2 rollups, or smart contracts, on the mainnet. Sharding focuses on processing transactions, while rollups manage state data storage off-chain. This synergistic approach enhances Ethereums scalability, both on-chain and off-chain.
While a definite timeline for shardings full implementation remains uncertain, discussions in the Ethereum community and the official Ethereum site indicate potential deployment in 2023.
Ethereums team is actively refining sharding plans for optimal efficiency, with danksharding emerging as a prominent contender.
Initial shard chains are anticipated to primarily bolster data availability, postponing direct involvement in smart contracts and transactions. When combined with rollups, this strategy is poised to significantly enhance scalability.
Rollups enable decentralized applications (DApps) to bundle transactions, store them off-chain, and create cryptographic proofs for blockchain submission. Alongside shard-based data enhancement, this synergy could make the vision of 100,000 transactions per second (TPS) a reality.
The long-term aspiration envisions versatile Ethereum shards capable of storing code, executing functions, and managing transactions. This complex task necessitates cross-shard communication for seamless transaction facilitation.
Current debates within the Ethereum community explore possibilities: eliminating state execution, having specialized smarter shards, or integrating zero-knowledge snarks (zk-SNARKs) for confidential cross-shard verifications.
Sharding promises remarkable potential and challenges for Ethereum and the broader blockchain industry. Proper execution could elevate Ethereums performance and decentralization. The road to full implementation involves strategic considerations and solutions for seamless cross-shard interaction, ultimately shaping the future of Ethereums scalability and efficiency.
Running a node on a sharded Ethereum network is open to everyone. Unlike traditional approaches that increase the database size, risking centralization, sharding empowers Ethereum to scale while preserving decentralization.
In a scaled network with a growing database, validators must meet demanding technical specifications, including costly hardware, electricity expenses, cooling systems, and upkeep.
This scenario inadvertently paves the way for centralization due to high entry barriers. Sharding, however, circumvents this by not mandating validators to store the entire networks state data locally. Innovative data techniques, like zero-knowledge Rollups, verify data availability without the need for complete storage. This breakthrough fosters a decentralized network while promoting scalability on Ethereum.
Shardings enduring advantage on Ethereum lies in bolstered participation. With scalable and secure network capabilities, the ultimate goal is to enable Ethereum to be run on everyday devices like laptops and mobile phones.
This accessibility surge will render Ethereum clients more user-friendly, paving the way for a broader global user base. This shift aligns with the overarching objectives of security and decentralization, as a decentralized network significantly mitigates the risk of attacks or system failures.
Sharding will revolutionize Ethereums speed and throughput by liberating transaction processing from the confines of a single chain. Projections suggest that sharding could elevate the networks transactions per second by significant margins, approaching the levels achieved by established payment systems such as Visa or PayPal capable of processing thousands of transactions per second. This advancement marks a pivotal step towards Ethereums efficacy and its potential to rival traditional financial systems.

dYdX Community Votes On Appchain Migration and V4 Deployment – Yahoo Finance
The dYdX community is voting on a governance proposal formalizing plans to convert its DYDX token into a network token ahead of the projects appchain migration and v4 launch.
The proposal, floated on Aug. 28 by Wintermute, a top crypto market maker, outlines plans to make DYDX the network token for the forthcoming dYdX Chain. The roadmap includes launching a one-way bridge allowing users to migrate DYDX from Ethereum to dYdX Chain.
The plan has garnered unanimous support so far, although voting has only been live for a few hours. The DYDX token is up 2% in the past 24 hours.
dYdX Community Votes On Appchain Migration and V4 Deployment
dYdX is the leading decentralized perpetuals exchange, routinely processing over $500M in daily trading volume. The protocol exceeded $1T in cumulative all-time volume on July 14.
If passed, dYdX would exit the Ethereum ecosystem and launch its v4 iteration on a Layer 1 appchain exclusively dedicated to it.
dYdX first launched on Ethereum in 2017, quickly emerging as the top decentralized exchange supporting leverage.
dYdX then moved to its own StarkWare-based Layer 2 in 2021 after mainnet gas fees surged following DeFi summer in 2020. The increase in scalability enabled dYdX to roll out new features and increase its number of supported pairings from three to 30, and positioned dYdX as a top three Ethereum Layer 2 network by throughput from mid-2021 until Q2 2023.
But last June, dYdX announced that its forthcoming v4 protocol will launch on a dedicated Cosmos-based blockchain. dYdX said the move will enable the launch of advanced features including a decentralized, off-chain orderbook and matching engine capable of scaling to orders of magnitude more throughput than any blockchain.
Wintermute also recommends launching a new Ethereum-based token, wethDYDX, to perform governance and utility functions for dYdX v3 which will continue to exist on Ethereum after the launch of dYdX Chain and dYdX v4.
Per the proposal, users that bridge their tokens over to the new chain will automatically receive a corresponding wethDYDX balance on Ethereum, further incentivizing holders to migrate their tokens onto the dYdX Chain.
Story continues
Wintermute notes that launching wethDYDX is the only aspect of its proposal requiring changes to the protocols smart contracts. As such, launching wethDYDX would require a secondary long-timelock proposal following the approval of the current proposal.
All other items contained in Wintermutes proposal (launching dYdX v4, adopting DYDX as the network token of dYdX Chain, and launching a one-way token bridge for DYDX from Ethereum) would be fully ratified by the Snapshot poll that is currently live.
Voting will end on September 1.
