Saga aims to create a new system for web3 project developers. Currently, most developers have to choose between the ease of working on an established chain like 

 versus the convenience and customization of designing their own chain. The Saga team realized that the most effective option for game developers would actually be a combination of the two types of development environments.

Saga wants to let developers set up their own sovereign blockchain so they can decide how things like 

 and transaction fees work. However, Saga also aims to provide extensive support for developers in its ecosystem. Its underlying framework ensures that people still have excellent security and a reliable validator set, no matter what their gaming project is.

 and the shared security system of the Cosmos ecosystem to manage the network, and has created its own Layer 1 chain that runs the entire Saga ecosystem and can do things like automatically launching 

The Saga Mainnet handles each developer's compiled smart contract binary. However, it also runs parallel dedicated chains that function as virtual machine (VM) modules capable of handling a specific set of smart contracts. End users for blockchain games and other apps interact only with the dedicated blockchain, while the developer's system manages the fees and individual transactions on the Saga Mainnet.

All of the chains on Saga are validated through optimistic coordination, which requires every Saga validator to validate each chain in the Saga ecosystem via 

 validation, verifying transactions by temporarily locking Saga tokens.

The Saga network contains a lot more than just the basic features offered through the Cosmos SDK and ecosystem. In addition to the software development tools and helpful interface for Saga's validators and developers, the ecosystem also contains the following features.

The overall layout of the Saga ecosystem starts with the Saga Mainnet. Built on the Cosmos hub, this framework includes a full validator set and a dedicated blockchain for handling all smart contracts. The basic protocols are passed on to each child chain in the system, and information is relayed back and forth between the main chain and all of the secondary chains. Saga's validators stake tokens, and then check to make sure every element of the topology follows Saga’s regulations.

 are a method for creating a dedicated blockspace that a developer can manage. These chainlets function as virtual machines that can handle smart contracts and automatically launch Celestia rollups. Each chainlet is its own blockchain that handles nothing but a specific gaming project. Developers decide on the gas fees they'll charge users, and can add chainlets as their projects expand and require more throughput from the remaining validators.

Saga's shared security relies on both the Cosmos hub and its own set of validators to secure the network. Validators on Saga’s network are monitored by auditors who can catch potential issues with individual dedicated chains. If anyone in the validator set fails to properly confirm a smart contract, their staked tokens are automatically confiscated.

Currently, the Saga team is in the Pegasus phase, which is about releasing tokens and opening the Saga Mainnet to the public. Sometime in late 2022, Saga’s team hopes to reach their Mainnet V2 phase, which will prioritize a new version of the Saga Mainnet with more features and options for dedicated blockspace.

SAGA tokens are the primary method for paying fees on the Saga network. These tokens are also used for staking, and function as a method of confirming Saga transactions. There are a total of

SAGA has done an extremely impressive job of attracting users, and seems poised to become the big coin debut of April 2024 with its high price.

However, it's hard to say whether SAGA can maintain its price in the long run. It's quite common for new startups to have a strong start and then drop in price once their project fails to take off.

Its helpful features and low transaction fees have already attracted many people, and it's no surprise that many others are interested in the project. Furthermore, SAGA tokens have had a promising start with extremely impressive growth. If the Saga company can successfully capitalize on its early buzz, it has a bright future.

Saga (SAGA): Catalyzing the Multiverse With Scalable Chains

Discover Masa, a platform empowering individuals to control and monetize their data, decentralizing AI storage and promoting ethical data sharing.

Few areas of the crypto industry are as popular these days as artificial intelligence (AI). AI-related tokens and projects experience some of the highest growth rates, with particular interest attached to generative AI technology and large language models (LLMs), all thanks to OpenAI's massively popular ChatGPT tool. This is no surprise, as blockchain technology has the potential to address many of the limitations of LLM algorithms, particularly those related to the issues of data and centralization of AI models.

The Masa network (MASA) is a new AI-focused crypto platform that brings a fresh paradigm to the world by allowing individuals to control and monetize their personal data. Its platform also contributes to the AI revolution by decentralizing the storage of both the user data and the LLMs utilizing it.

 (MASA) is a blockchain platform that provides access to user-consented, hyper-specific behavioral and personal data and decentralized LLM algorithms. 

The platform launched its operations on Apr 11, 2024. Masa operates as a subnet on the 

 (AVAX) blockchain. To enable cross-chain functionality, it has also integrated 

 technology. This lets Masa bridge assets, initially to two key blockchains, 

 (BSC), with additional chains to be added in the future.

Masa provides user-consented AI data that’s stored in a decentralized way. As of mid-April 2024, more than 40 million data points from over 1.4 million 

 user wallets are available via its permissionless data layer. Masa represents an entirely new decentralized AI paradigm: while most data providers use centralized storage solutions, its platform's data is always stored in a decentralized, blockchain-based format.

The data made available via Masa’s platform is user-consented for collection and privacy-protected using its Zero-Knowledge 

 (zkSBT) technology, which allows users to share their personal data securely and confidentially by storing this encrypted data on the blockchain. Thanks to the zkSBT, users can share fairly detailed personal data while protecting their identities and the specifics of their online activities.

This user-consented data is directly sourced from users through the Masa App and Masa Chrome browser extension with their consent. Users have complete control over their data, which is collected in a highly detailed, verified and ethical manner. 

As such, it's different from the typical user-aggregated data collected from the internet by companies. Compared to user-consented data, user-aggregated data tends to be less granular and, obviously, has ethical strings attached to it: in most cases, users don't consent to the collection of such data, or (at best) provide reluctant consent by clicking on annoying "Accept All Cookies" buttons.

While focusing mostly on user-consented data, the Masa platform also offers developers a way to access user-aggregated data for a richer data network. Using Masa's web data scraper, developers can extract data from websites, social media posts, blogs and online databases.

User-aggregated data is collected by data node workers via the Masa Oracle network and Masa Chrome extension and stored on the platform, benefiting from the 

In addition to datasets, Masa enables the decentralized execution of LLM algorithms, facilitated by the Oracle node workers, who leverage their surplus CPU and GPU computing power to run open-source LLMs for fine-tuning AI models.

The Masa project aspires to achieve goals crucial to the development of all data and AI industries. First, Masa allows individuals to completely control their own personal data by choosing what to share with the outside world while protecting their confidentiality. The blockchain-based storage mode also ensures the security of the stored data. Additionally, users can monetize access to their personal data, becoming a major beneficiary of its use.

All of these benefits are in stark contrast to the traditional way user data is collected, stored and used on Web 2.0 platforms. In this traditional mode, one is often unaware of what personal data is collected about them, as well as when and by whom. Although the data used for analytics purposes might be in an aggregated form, together with the details of other online users, individual users are still part of the "guinea pig" cohort whose details have been unceremoniously extracted and utilized without their knowledge or consent.

Moreover, when hit online with some fairly relevant advertising based on past search phrases, one begins to realize that data isn't always used in an aggregated format. In fact, its utilization can be quite personalized. And of course, in the traditional mode of data collection, we’re all rarely reimbursed for the data we share.

Another aim of the Masa project is to provide a secure and efficient decentralized infrastructure for running LLM algorithms. Traditional, centralized hosting solutions for AI models face challenges, such as technical capacity and security issues. For instance, many centrally hosted LLM-based solutions suffer from performance degradation when large numbers of users access them simultaneously. Masa's approach to leveraging decentralized resources for running open-source LLMs efficiently addresses these capacity limitations, providing enhanced scalability and reliability for AI applications.

Masa operates as a subnet on the Avalanche blockchain, using cross-chain communications supported by LayerZero to access other networks as well. Avalanche subnets are completely independent 

 networks with their own set of rules and functionalities. Subnets, including Masa, use Avalanche's validators, or a subset of validators, to secure the network and achieve consensus.

Besides the validators, the Masa network has another type of functional nodes — 

. These special Masa nodes play a critical role in providing structured data and advanced AI models while prioritizing data privacy.

The Masa Oracle network acts as a decentralized web scraper, gathering data from the internet and organizing it for AI training and development. This approach gives developers access to hyper-personalized training data to improve language model performance. It also supports the decentralization of LLMs, making them easily accessible without complex setup.

As mentioned above, users can manage access to and monetization of their personal data via Zero-Knowledge Soulbound Tokens (zkSBTs), which provide a secure way of providing access to users’ personal data without compromising their privacy.

 is the main gateway for users to interact with the Masa platform. It lets them provide access to personal data and earn crypto rewards by staking data in four different ways:

Masa’s native cryptocurrency, MASA, is a utility and 

 used to reward users for providing their data to the network. 

 MASA also earns you crypto rewards. Entities who wish to utilize data held by the network pay for access to it in MASA tokens. The token is also used to reward the Oracle nodes.

As a governance token, MASA lets you participate in votes on any changes and upgrades to the platform's rules or fee structure.

The token's supply economics doesn't specify a maximum cap. MASA's total supply is 1,588,866,523, which will be released gradually over a period of around four years starting in April 2024. Token supply allocation shares are per the table below.

The MASA token is available on Bybit via a 

. Bybit's Spot and Derivatives markets provide you with opportunities to trade hundreds of cryptocurrencies and crypto-based products. If you don’t have a Bybit account, you can easily 

 to access Bybit's range of crypto products and assets.

The Masa network is a refreshing addition to the data industry, whose user consent and privacy have been under attack for many years. The Masa platform puts data ownership in users' hands, allowing them to control access to their data and benefit from its monetization. As online privacy concerns and invasive Web 2.0 advertising shenanigans grow, more users will be attracted to Masa's unique data concept.

In addition to allowing individuals to control and monetize their data, Masa also contributes significantly to the development of 

, which is important because the decentralized mode of data and model storage championed by the platform has the potential to solve many technical limitations of LLMs and other types of AI algorithms. This is a network full of merit and promise; all it needs now is wider recognition and user adoption.

Runes Protocol Revolutionizes Bitcoin with New Token Capabilities Ahead of 2024 Halving

Nolus is a decentralized finance lending protocol with cross-chain capabilities. Learn more about how it works in this article.

One of the big advantages of decentralized finance (

) is that it provides more options for users. People who cannot get traditional loans because a typical bank deems them "high-risk" can turn to the DeFi sector to borrow crypto assets. The Nolus Protocol is a new DeFi lender that offers users all sorts of exciting opportunities. To see how this intriguing project works, explore this guide to learn all about Nolus.

 is a DeFi lending protocol. It has cross-chain capabilities that let people choose the most favorable rates possible and avoid the need to save up funds for liquidity.

Nolus was founded by Ivan Kostov and Kamen Trendafilov. Kostov worked in traditional finance, while Trendafilov has a background in marketing and business. During their time in these sectors, Nolus's founders realized that blockchain networks had the potential to revolutionize banking. They decided to join together and create a new leasing system that makes the most of DeFi products instead of just trying to mimic past banking methods.

Nolus started work on its plans in 2022 and officially launched its mainnet in 2023, having successfully completed several investing rounds and receiving 

 Token Metrics, Autonomy Capital, Everstake and more.

Nolus aims to tackle three problems common in crypto lending markets:

 software developer kit (SDK). Its code is entirely open sourced, and is updated and changed only when all stakeholders in the Nolus community vote to do so. According to the Nolus white paper, its ecosystem’s goal is “to build a novel user experience–driven automated money market” that facilitates direct interactions between lenders and borrowers without involving any other users.

The Nolus lending method starts with lenders choosing to supply 

 to the system. Any borrower who submits a down payment can get a loan from this supply of stablecoins. Both the coins and the down payment are 

, and interest is determined based on the value of the items. There’s no fixed repayment schedule, but the smart contracts ensure that interest is automatically removed from the collateral, and then paid to the lender at regular intervals. Once the user decides to repay the lease, the original assets are released from the smart contract.

Nolus's lending protocol includes many ways for customers to profit and enjoy convenient services. Here are the main DeFi products you can access through Nolus.

DeFi leasing on Nolus is designed to be as convenient as possible. Customers don’t have to go through a lengthy application or pay a lot of fees to other users. You just enter your collateral and get a loan of up to three times the value of the initial investment. Interest rates vary between 11% and 18%, based on the market value of the digital assets. The 

 allow the loan to be repaid on your own schedule. However, keep in mind that you pay more interest if you wait a longer amount of time to repay the loan.

If you want to earn money based on your existing crypto, you can join one of the many 

 on Nolus by submitting stablecoins in exchange for interest-bearing Nolus crypto. When you're ready to withdraw your funds and stop participating in DeFi leasing, you can cash out your Nolus tokens to receive your initial asset, plus any additional interest or network fees you’ve earned.

Nolus's system of money markets isn't the only thing they provide. Users who decide to 

 a crypto asset on Nolus can earn more money. The Nolus ecosystem offers the option of staking NLS tokens in exchange for various incentives. Lenders receive higher amounts of rewards for lending stablecoins, and borrowers get a lower interest rate.

Nolus has had some impressive growth since its launch in 2023. In just six months, the lending protocol has assisted with thousands of loans, collectively worth $8.6 million in total. Its team calculates that they've managed to achieve an average 

Nolus hopes to expand on this momentum in 2024. Its main plan is to continue marketing the lending protocol heavily, attracting more users who want to do their own research and find the best possible loans. To further attract users from the DeFi sector, Nolus aims to add more support for other crypto tokens and increase network liquidity. Nolus stands for community-led governance, so they don't have a long-term road map in place. Instead, they plan to evolve and adjust to suit whatever community needs arise in the future.

. It allows users to adjust their interest rates, and it's also a 

. People with NLS tokens can vote on how the platform is run and help implement new changes for the platform. The NLS token has a total supply of 1 billion. Nolus’s plan is to gradually mint tokens over a ten-year period, and implement a token buyback program to help maintain value. NLS token distribution will be as follows:

When the NLS token was released in the summer of 2023, Nolus prices were fairly stable. However, now that investors can sell their NLS tokens, prices have become more volatile. Starting in December 2023, NLS prices 

, and although the token currently seems to be dropping from its all-time high of $0.10, more price increases seem likely in the future.

Not only is the market for the NLS token quite bullish right now, but the Nolus lending protocol is also attracting a lot of positive attention in the crypto space. If the network can maintain its positive attention and attract more users, prices seem likely to rise even further. CoinCodex predicts Nolus prices will stay in the $0.04 to $0.19 range for 2025, and hit 

. This attitude is backed up by crypto influencers such as Crypto Revolution, 

 an underrated crypto with a lot of potential for growth.

The Nolus project is a well-thought-out crypto protocol that offers users significant advantages. Its innovative approach to lending could potentially attract a lot of users from the DeFi space. In addition to having a reliable system backed with effective technology and a detailed white paper, NLS digital assets have also experienced some promising growth patterns. The crypto asset has had a slow yet steady climb in price, and now that it's trending in crypto news, it seems poised to take off.

However, keep in mind that it's still important to 

 on digital assets. Some crypto investors might find it concerning that the Nolus project is mostly backed by marketers, instead of blockchain enthusiasts. There have also been some tech issues, such as the 

 that led to some unnecessary margin calls. Subsequent issues could limit price appreciation of its crypto assets. Therefore, it's necessary to approach Nolus with caution and not overextend your finances.

Nolus's DeFi lease system allows people to obtain easy access to crypto. Its innovative approach provides investors with significant advantages. Unlike traditional finance, there's no lengthy application process, and in contrast to many other blockchain networks Nolus doesn't have frequent margin calls or high network fees. As long as Nolus doesn't run into any technological issues or financial problems, its network is likely to have a lot of success in the DeFi space.

Nolus (NLS): Crafting Liquidity's Future With Leading DeFi Leases

Blockchain

The popularity of cryptocurrency and blockchain has been growing exponentially, significantly increasing the number of users and transactions. This has caused infrastructural bottlenecks for blockchain network operations. To achieve mainstream adoption, the industry needs to look for solutions to resolve its scalability issues in order to cater to the burgeoning numbers of users, transactions and data.

Two of the main solutions employed by the industry include Layer 1 and Layer 2:

In this article, we’ll be exploring the 

, and how to help blockchains achieve scalability. 

 refers to the conundrum of a blockchain simultaneously achieving the following three characteristics:

It’s argued that any system can only achieve two out of the three characteristics, forcing it to give up on one.

Typically, blockchains have struggled with the blockchain trilemma. Let’s take a look at a few prominent examples.

Ethereum is decentralized and highly secure, with approximately 

 validators. It’s nearly impossible to attack Ethereum’s blockchain, as it would require an attacker 

 of the validators in order to compromise the network. However, this comes with a trade-off in scalability, which is why Ethereum’s network fees rocket during times of high activity.

In contrast to Ethereum, BNB Chain only allows a maximum of 

. It’s therefore apparent that BNB Chain isn’t decentralized. However, this allows it to achieve a high degree of security and scalability. 

The definition of the word “scalability” varies from expert to expert. However, at its core,

 refers to a system’s capacity to offer a rich experience to every user, irrespective of the total number of users at any given time.

 refers to the number of transactions a system handles per second. While companies/payment channels like Visa process nearly 20,000 

 with the VisaNet electronic payment network, Bitcoin’s

The difference in capacity might be shocking, but there’s a simple explanation behind it. Bitcoin adopts a decentralized system, while VisaNet runs on a centralized system. The former utilizes more processing power and time to safeguard the privacy of its users. Each data transaction has to go through multiple steps, including acceptance, mining, distribution, and validation by a node network.

With cryptocurrency expected to become an imperative force in the business world, blockchain developers are trying to increase the scope of blockchain handling. By creating blockchain layers and optimizing Layer 2 scaling, they want to speed up processing times and ramp up the number of TPS.

Let’s use Ethereum as an example. In blockchain technology, a consensus mechanism is a fault-tolerant system that allows agreements on a single network state in distributed nodes. These

 ensure that all nodes agree on transactions and are synchronized. This makes the Ethereum chain immensely difficult to overwrite or attack.

Due to the stability and security of Ethereum, the

 began, leading individuals to create cryptocurrencies and decentralized applications (

) on the blockchain. Consequently, there was an influx of users and an uptick in the number of transactions made on Ethereum. As the system became clogged, the transaction fee — or 

 paid to parties processing transactions on Ethereum’s network — increased.

When a blockchain network is clogged, pending transactions end up in the memory pool and take more time to process. To tackle this, miners start prioritizing transactions that have higher gas prices in order to confirm them. This further raises the minimum cost required to make a transaction.

The cycle of price increment gets to a point where gas fees skyrocket, making the situation worse for everyone. Layer 2 scaling is aimed at providing a solution to this problem and lowering the costs of transactions.

Layer 1s are the primary blockchain network on which other blockchains and DApps are built on. They are able to support transactions and operations that are conducted on the blockchain. To improve scalability, a Layer 1 will have to make direct changes to the blockchain’s code or architecture. Examples include enhancing the speed of block confirmation or increasing the data-containing capacity of a block.

Ethereum, Binance Smart Chain and Solana are the most prominent Layer 1s.

Let’s take a look at some Layer 1 scaling solutions.

 (PoW). Even though a PoW system is highly secure, it can be slow. This is because it requires substantial computing power to solve cryptographic algorithms. Ethereum started off with a PoW consensus mechanism, which led to severe network congestion when a large number of users came onto the Ethereum network.

Ethereum has since switched over to use a 

, and now processes and validates new blocks by consensus from the network. This switch has allowed Ethereum to change its speed from 

. This is achieved while retaining decentralization and security.

Layer 1 scaling solutions are usually introduced by the blockchain’s development team. Forking a chain means upgrading or adjusting a blockchain. There are 2 types of forks: 

Soft forks are architectural changes that are compatible with the existing blockchain. On the other hand, hard forks are changes to the blockchain architecture that is distinctly different from the existing one. 

, which helped increase the network’s performance from approximately 1,600 transactions per block to 3,000.

Whereas larger changes to be made to the blockchain, such as increasing Bitcoin’s block size to 8MB, requires a hard fork. This will create two versions of Bitcoin, one updated and one old network.

 is one of the scaling techniques that divides large transaction sets into smaller data sets known as "shards". The network processes these network shards concurrently in parallel, enabling sequential work on several transactions rather than having a network process each and every transaction sequentially. This is a faster and more effective mechanism.

Furthermore, rather than keeping a copy of the blockchain in its entirety, each network node is assigned to a certain shard. Individual shards exchange addresses, balances, and general states utilizing cross-shard communication protocols while also providing proofs to the mainchain.

Examples of blockchains that have integrated sharding are Ziliqa and Tezos.

However, it should be noted that Sharding is experimental and no Layer 1 has successfully implemented it yet.

A Layer 2 enhances the scalability and efficiency of a blockchain protocol by running on top of it. It will enable transactions away from Layer 1 using an external, parallel network.

To finish the transaction results, Layer 2s takes bundles of transactions from the main chain, processes them on their behalf, and then bundles the transactions back into Layer 1. The Layer 1 blockchain becomes less crowded and ultimately more scalable by abstracting the majority of data processing to auxiliary architecture.

Prominent examples of Layer 2s are Polygon, Optimism, Arbitrum, zkSync and Bitcoin’s Lightning Network.

Here are some of the Layer 2 scaling solutions.

Nesting is one of the Layer 2 scaling solutions whereby a blockchain protocol houses other blockchains within or on top. The nested blockchain architecture typically involves a main blockchain that sets rules and parameters for a broader network, while executions are undertaken on an interconnected web of secondary chains.

The nested chain comprises both parent and child chains. The parent chain will delegate to the child chains to perform the transaction. The transactions will be carried out by the child chains, who will then inform the parent chain of the outcome. The parent chain will provide Layer 1 with the outcome once the transactions have been completed. 

Unless it becomes required for dispute resolution, the underlying base blockchain does not participate in the network operations of nested chains. Because everyone is working together, it is one of the greatest scaling methods and is quicker. The division of labor in this paradigm lessens the processing load on the mainchain, improving scalability tremendously.

An example of this is the OMG Plasma Project, which acts as a Layer 2 blockchain for Ethereum to ensure cheaper and quicker transactions.

Two-way communication between a blockchain and off-chain transactional channels can be facilitated through a state channel. The state channel is essentially a network-adjacent resource which carries out activities using a 

 mechanism, without the need for validation by nodes of the Layer 1.

Transactions can be executed without having to submit transaction data to Layer 1. Once the transactions have been completed, the final state of the channel will be sent to Layer 1 for validation. This mechanism allows to improve transaction speed and increases the overall throughput of the network.

State channels feature unmatched speed and privacy. Without the need to route through third parties such as miners, state channels are one of the best existing scaling solutions.

Both Raiden Network on Ethereum and Lightning Network on Bitcoin are examples of state channels. Both of these use state channels that are executed by hashed timelock contracts (HTLCs). While the Lightning Network allows users to complete a lot of microtransactions in a short amount of time, the Raiden will also let users run smart contracts through their channels.

State channels like Lightning Network are also entirely secure, since only the participants know about the transactions. On the flip side, the Ethereum Layer 1 blockchain records all transactions in a publicly auditable ledger.

Large batch transactions frequently use sidechains, which are distinct blockchain networks with their own sets of validators (and consensus mechanisms), which coexist with a Layer 1 to improve its speed and scalability.

With a sidechain design, the Layer 1’s main responsibilities are to uphold general security, validate batch transaction records, and settle conflicts. Once the sidechain has finished processing transactions from the main chain, assets are locked. Also, the majority of sidechains have a federation or other independent third party that double-checks to see if there are any irregularities in the activities between the mainnet and the sidechain.
