Users Can Now Deploy Smart Contracts on XRP Ledger Through this Ripple Partnership – The Crypto Basic

Ripple has partnered with EasyA to introduce educational content aimed at helping individuals learn how to deploy smart contracts on the XRP Ledger (XRPL).

While the XRPL boasts several benefits that set it apart from other blockchains, the network does not support smart contracts, a feature intentionally sidelined during its development a decade ago to address potential security issues.

The XRPL now awaits the launch of Hooks, which will bring smart contract functionalities to the network. However, the Hooks protocol is currently delayed. At the moment, Ripple has partnered with Peersyst Technology to develop an EVM sidechain for the XRPL.

This EVM sidechain will help developers deploy XRPL smart contracts that are compatible with Ethereum but are not particularly native to the XRPL, as expected with Hooks.

It bears mentioning that XRPL Labs, the company behind the Xumm wallet, has already launched a sidechain with Hooks functionality called Xahau. The Ripple CTO Schwartz said Xahau is a good way to test Hooks before implementation on the XRPL.

Notably, the development of the EVM sidechain has reached the advanced stage, with the mainnet launch just around the corner. The latest update from Peersyst Technology revealed that work on the XChainBridge was close to finalization.

As the anticipation builds, Ripple recently partnered with Web3 educational resource EasyA to help individuals learn about the XRPL and how to deploy smart contracts on the network through the EVM sidechain with nothing but their smartphones.

EasyA has launched a learning module on this, comprising six challenges. The course, which spans Jan. 29 through July 31, begins with the history of the XRPL and ends with lessons on building an XRPL dApp and creating the front end of the application. The challenge is already open as of press time.

The collaboration between Ripple and EasyA, recently spotlighted by XRP community influencer Eri, holds significant importance for both the ecosystem and individuals aiming to implement dApps on the XRPL, providing a valuable starting point.

EasyA boasts a developer base encompassing over 750,000 individuals, featuring content for multiple blockchain networks like Solana, VeChain, Sui, and Polkadot. The XRPL learning course, tagged 60 Days of XRPL, will introduce the XRPL to this network of developers and others.

EasyA reports that its developers have secured funding from prominent venture capital firms, including Andreessen Horowitz (a16z). Notably, the developer pool comprises founders of noteworthy startups and individuals associated with esteemed universities and leading companies.

EasyA has also announced plans to extend invitations to outstanding developers from the 60 Days of XRPL challenge to a hackathon scheduled for April 2024 in London.

During this event, participants can pitch their startup ideas, vying for a chance to secure a $25,000 prize. Additionally, EasyA pledges to provide access to funding, grant opportunities, and mentorship for the most promising innovators.

Stellar foundation urges delay of Protocol 20 upgrade after bug discovery – Cointelegraph

The Stellar Development Foundation (SDF) smart contract upgrade on the Stellar blockchain is delayed until the end of January after its team found a bug in Stellar Core v20.1.0.

Weve decided to disarm our validators in support of postponing the Protocol 20 vote on Jan. 30 until after a bug fix, the SDF explained in a Jan. 27 blog post.

The foundation said the bug, which it found on Jan. 25, posed little risk but said it could potentially impact various applications. The SDF noted that a fix is already in the works, which should be available within two weeks.

However, the SDF stressed that it alone can decide whether or not to upgrade the network as it stands, as non-SDF validators on Stellar may still choose to vote in favor of the Protocol 20 upgrade on Jan. 30.

No matter the outcome, the SDF will continue to work to resolve the bug, and to engage in discussions with other validators in both public and private channels, the SDF added.

SDF said a quorum is required by voting validators for the Protocol 20 upgrade to pass. There are 43 validator nodes as of December 2023, according to Stellarbeat.io.

The bug occurs when a Soroban transaction request is made but results in a refund and is fee-bumped. Under the current code, the refund isnt sent to the fee-bumps source account as it should, the SDF explained in a Jan. 25 GitHub post.

Soroban is a smart contract platform that went live on a Stellar testnet in October 2022.

The SDF also launched a $100 million fund to attract developers to the platform in the same month.

One of Stellars core developers, Tyler van der Hoeven,noted in a Jan. 26 X post that Protocol 20 will be a phased rollout but didnt state how long it would take for a full implementation of Soroban smart contracts on Stellar.

Stellar is one of the oldest blockchain projects mainly focused on payments and asset tokenization. Stellar (XLM),the token powering the Stellar blockchain, currently boasts a market cap of $3.2 billion.

When Will Ethereum Hit New All-Time Highs? – Investing Haven

Ethereum set all-time highs on November 8th, 2021. Its highest daily closing price was $4807. Will Ethereum ever again hit its former all-time highs? If so, when exactly will Ethereum hit new all-time highs?

RELATED When Will Our Forecasted Price Of $10,000 Ethereum Be Hit?

In this article, we start by reviewing Ethereums fundamentals. We re-iterate that fundamentals are not the primary driver of price. If it were the case, then ETH should have hit ATH already in 2024, with its solid fundamentals.

We then transition to ETH price analysis, with the intention to derive an answer to the question: when exactly will ETH hit new all-time highs? In answering this question, we obviously also look at the pint IF we believe ETH will ever hit ATH again, or not.

Ethereum is considered a groundbreaking cryptocurrency project due to several key factors.

Smart Contracts and Decentralized Applications (DApps): Ethereum introduced the concept of smart contracts, self-executing contracts with the terms directly written into code. This innovation enables the creation of decentralized applications (DApps) on its blockchain, opening up a wide range of possibilities beyond simple transactions.

Decentralized Finance (DeFi): Ethereum is a cornerstone of the DeFi movement, providing the infrastructure for financial services like lending, borrowing, and decentralized exchanges without the need for traditional intermediaries. This has significantly expanded financial access and inclusivity.

Interoperability: Ethereum is designed to be interoperable with other blockchains, fostering collaboration and compatibility between different projects and networks.

Upgrades: Ethereum has undergone various upgrades, with Ethereum 2.0 being a significant one aimed at improving scalability, security, and sustainability. These upgrades demonstrate the commitment to evolving and addressing the challenges faced by the network.

Community and Developers: Ethereum has a vibrant and active community of developers, contributors, and users. This ecosystem has played a crucial role in the ongoing development and improvement of the platform.

A critical point to understand is that fundamental value doesnt always dictate short to medium-term price movements.

Thats why fundamental analysis will never answer the question whether ETH can hit new ATH. It certainly will never be able to answer WHEN ETH can hit new ATH.

These questions can only be answered by completing fundamental analysis with thorough chart analysis.

In traditional financial markets, company performance and earnings reports can have an immediate impact on stock prices. The crypto space operates in a realm where speculative sentiment, market trends, and macroeconomic factors often take precedence.

Fundamental developments like technological upgrades, partnerships, or protocol enhancements may indeed enhance the long-term viability of a cryptocurrency project. However, their impact on price is frequently delayed and subject to broader market dynamics.

Applying this principle to Ethereum, a prime example emerges. Ethereum is a powerhouse of decentralized finance (DeFi) and smart contract functionality. Despite this, Ethereums short to medium-term price movements are heavily influenced by market sentiment, speculative trading, and crypto market momentum. This is evident in the historical performance of Ethereum. The fact of the matter is that fundamental advancements, such as the Ethereum 2.0 transition, havent always translated to immediate price surges.

Still, the recognition of Ethereums robust fundamentals positions it as a long-term player. Our forecast of a new all-time high (ATH) in 2025 or 2026 aligns with the understanding that, over time, the market tends to reward projects with solid fundamentals as they contribute to the sustained growth and adoption of the platform. This forecast reflects a belief in Ethereums enduring strength rather than a prediction of short-term price movements based solely on immediate fundamental developments.

The short answer: YES, Ethereum will set new all-time highs, in the not too distant future.

There is too much momentum in markets for ETH not to hit new ATH.

In order to answer the question will ETH ever hit new ATH, we have to look at the weekly chart.

It is clear from the long term ETH chart that a long consolidation is ongoing which has some similarities with the consolidation that occurred back in 2018/2019, after ATH were hit in the last days of 2017 / first days of 2018.

The current setup on Ethereums price chart is bullish, its a simple as that. Only if ETH falls below $900, which is seems very unlikely to happen in the coming 2 to 3 years, will the bullish setup invalidate.

Moreover, as seen, there is a very important price point that will act as the line in the sand which is $3525.50. Once past this price point, it is a given that ETH will hit ATH.

With the bullish long term chart reversal, and the pre-requisite that ETH will clear $3525.50 sooner or later, we believe that ETH will hit ATH in the not too distant future.

The next question that comes up, given the analysis discussed before, is WHEN ETH can set new ATH?

Investors nowadays tend to set expectations very high. They not only want to know WHEN but they also want the answer to be more precise. Many will ask WHEN EXACTLY will Ethereum print new all-time highs?

Nobody has a crystal ball. Any answer to the ATH prediction question has to be prefaced by the underlying assumptions as well as confidence levels.

We are saying, with a high level of confidence that Ethereum will move to new ATH in 2025.

The daily ETH chart helps us tremendously to come with this forecast. The rising channel on Ethereums chart says it all: an uptrend, though a soft one, is headed towards $3525.50. Thats where Ethereum will hit big resistance. We expect $3525.50 to be hit in 2024, with a very high level of confidence.

Our base case outcome is a drop after $3525.50 is hit. This should result in a consolidation and fast move to previous all-time highs at $4807 in 2025. Frankly, the chart setup confirms our thinking.

One very important note: many investors tend to mix up chart analysis with technical analysis. The problem with technical indicators is that they are lagging. They are also not able to identify price targets, mostly not.

All charts shown above are based on advanced ETH charting analysis, not ETH technicals.

In summary, Ethereums journey to new all-time highs is like a puzzle where its strong foundations meet the unpredictable nature of the crypto market. While Ethereum is known for its smart contracts, DeFi features, and regular upgrades, predicting its short-term price changes involves understanding how people speculate in the crypto world.

Our belief that Ethereum will reach new all-time highs in 2025 or 2026 comes from looking at both its lasting strengths and how the market is right now. We use charts to help us see where the price might go. The $3525.50 price is crucial, and when Ethereum passes that point, its a big deal. While its hard to say exactly when this will happen, were quite sure it will. Our forecast is like saying we expect a big jump in 2025.

As we keep exploring the world of crypto, watching Ethereums comeback isnt just about numbers. It is about understanding the energy and strength in this special project. When exactly Ethereum reaches new all-time highs in 2025 will be part of the natural flow of the market. We will share updates, insights, and a better understanding of the crypto world in our ongoing analysis.

Metadata in Blockchain: What Is It and How it Works? – Crypto Times

The dynamic realm of blockchain is continually expanding and tons of newer applications are introduced on top of it regularly. As the adoption of blockchain technology is going through a major paradigm shift, its utility is extending beyond just transferring cryptocurrency assets from one address to another.

Blockchain provides magnificent data storing facilities with numerous functionalities and metadata is one of them. This feature has an important role in enhancing adaptability, efficiency, and accessory for blockchain transactions.

Metadata is the additional information attached to blockchain transactions. It contains comprehensive details of a transaction such as timestamp, sender/receiver, gas fee, or any textual content. As the transactions on the blockchain are irreversible, the metadata is added to give it context for references.

While the primary function of a blockchain is to perform transactions, metadata enables those transactions to have an identity or referential sub-content. This feature essentially improves the functionality further than just the transfer of crypto assets.

Metadata could be also described as Data for Data as it provides extra details regarding the data or assets being transferred.

Metadata is mainly of two types:

On-chain metadata is directly stored on the blockchain as a part of transactions. It includes information such as transaction labels, remarks, and references or links to other contracts. This information can be seen and accessed by anyone as it is stored on the blockchain.

Off-chain metadata is added to the transaction but it is not directly stored on the blockchain. Such data is mentioned in the transaction via links or outgoing references, leading to other documents, filings, or sources available on the Internet.

While on-chain metadata is included in the blockspace, off-chain metadata remains non-subjective to the transaction processing hence it is used in need of elaborative metadata.

Most of the on-chain metadata is associated with transactions such as transaction properties and smart contract code. This data is an integral part of the blockchains data structure, and it is permanently stored across all the copies of the blockchain that nodes download.

All blockchain transactions have some elementary metadata, which contains basic details such as sender and receiver address, transferred asset amount, and timestamp. Like transactions, the smart contract code and its associated data, including functions and variables, are also stored as on-chain metadata in the blockchain.

All these on-chain data are accessible through blocks for verification, which can be found via block headers. On the other hand, off-chain metadata is not primarily stored on the blockchain.

The intent behind doing so is that sometimes metadata consists of larger files or content that may increase the size of a transaction. This kind of metadata is stored on external storage sources like IPFS, which provides an ideal decentralized data storage option.

Metadata is added to blockchain transactions using smart contracts. Besides elementary metadata, which is automatically generated while the transaction is executed, external metadata can be added using this method.

Although it requires users to have some coding experience as it needs to be inserted within the smart contract code. To do so, a smart contract first needs to be created. Below is a Solidity smart contract code block that shows how metadata is added manually.

In the example, adding metadata involves creating a string variable inside the contract. We have created a smart contract, CryptoTimes, and defined a variable using string data type. String variables can be assigned with any value in text format, including numbers, messages, links, etc.

The user will need to provide metadata as input when this contract is executed. Before sending the transaction, the sender will have to communicate with this contract. It can be done by using existing libraries such as web3.js and ethers.js.

Some Ethereum wallet also allows adding metadata while sending transactions which does not require such coding.

Blockchain metadata can be used for a wide range of applications. Every project using blockchain in its infrastructure can benefit from Metadata. Below are the applications where blockchain metadata can be used;

The application of non-fungible tokens (NFTs) is one of the most beneficial with Metadata as it stores the creators name, previous owners, characteristics, and more. All this information is critical for any digital collectibles or NFTs.

Several digital assets deployed on blockchain contain unique details stored using Metadata. It can help authenticate a crypto asset while also enabling it to have specified values.

Metadata is one of the most important elements of a smart contract. As these contracts are self-executing, Metadata can provide conditional information to enforce the transactions on the blockchain.

The blockchain-based supply chain ecosystem can utilize Metadata to improve product traceability and transparency. It can also provide details on product authenticity and additional details about goods or services.

Metadata enables efficient data recording and managing processes as it could add labels to data records. This allows simplified data access as metadata properties allow one to sort or find specific records from large data structures.

Metadata can also be used in digital identity management as it makes it possible to enter personalized credentials and information for user directories. Groups, organizations, or even governments can benefit from this application while inheriting the security of blockchain technology.

While metadata enables additional functionality, it also needs to be noted that metadata requires block space to be stored on the blockchain. The higher the size of metadata, the more space it needs. It could also require more gas fees associated with the transaction as the size of the transaction will also increase.

In the coming time, blockchain metadata could potentially become an essential functionality as this technology is rapidly shifting toward retail applications. It can also become an epicenter for developing newer applications that inherit immutability, security, and several other maneuvering characteristics of blockchain technology.

Ans. Onchain metadata refers to the elementary data, such as transaction sender/receiver details and timestamps, while offchain metadata includes links or references to external information.

Ans. Blockchain metadata can not be deleted as it is stored on the blockchain. The blockchains features of immutability and irreversibility do not allow the deletion of metadata.

Ans. Metadata is inserted in the transaction using a smart contract, and it is permanently stored on the blockchain after the transaction is broadcast.
