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.

 ecosystem, whose interchain web development standard is a set of protocols that allows a broad variety of blockchains to communicate with each other. The Saga network uses the 

 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.

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.

 consists of four separate phases. The company has already completed the Andromeda and Cassiopeia phases, which focused on designing the Mainnet and setting up the system of Saga validators. 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. If the Saga ecosystem can’t attract new developers and continue to release impressive projects, investors could see some major SAGA losses in the future.

By offering developers the chance to create their own dedicated chains, Saga offers a more convenient and scalable system for blockchain gaming. 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

Anyone can run a node to keep the reliability of data storing in the distributed ledger. But do you have what it takes to run a node? Learn how it works.

Types_of_Nodes_on_a_Blockchain.jpg

A node is a point in a network that either distributes data to other nodes in the network or is an endpoint of a network. A typical blockchain node may be interconnected to several other nodes in a network.

In a blockchain, the node is usually a device such as a computer, laptop or server. Blockchain nodes can perform a lot of different functions, such as validating or rejecting a block of transactions. A node can also save and store the transaction history inside a block. Similarly, it can distribute the transaction history to other nodes for safekeeping and future reference.

Blockchain technology has become immensely popular because it is thought to be tamperproof. Besides offering a secure environment for financial transactions, a blockchain network is self-regulating, which prevents unauthorized intervention and manipulation.

Whenever a transaction takes place on a blockchain, the record of the transaction is recorded and distributed to every node in the network. The transaction is recorded on a block. A block can contain records of millions of different financial transactions.

Since a copy of the financial record is distributed to every node in a network, it’s almost impossible to manipulate the record of a financial transaction. This is because the person attempting the manipulation would need to change the record kept across thousands of nodes. In theory, the system will catch any manipulation because the unauthorized change will not correspond to the record kept across the network.

How Does a Financial Transaction Get Recorded in a Blockchain Network?

Due to the decentralized nature of a blockchain network, the system automatically authenticates a financial transaction. In the first step, the transaction is authenticated by the user, who employs a private and public key to access the network. In the second step, a block is created, representing the transaction. Subsequently, the record of the transaction is sent to every blockchain node in the network.

Once the transaction is agreed upon between the user, the node will validate the transaction. If a majority of nodes validate the transaction, it is added to the existing blockchain. Any updates are also distributed across the network, which completes the transaction cycle.

A blockchain node is a device on a blockchain network, which keeps a copy of the transaction on the network and may perform essential functions such as validating and authenticating a transaction.

Based on the specific role of a blockchain node, it can:

The role of a specific type of node may differ from that of another node. For instance, certain nodes are programmed to validate a transaction, while other nodes are only responsible for recording the transaction. Sometimes, a node also shares the data with other nodes.

Nodes are also classified based on their availability. An “online node” is one that continuously sends updates to the network. It is always active. In contrast, an “offline node” is not always connected to the network. When connected, these offline nodes are required to download and update a copy of the ledger in order to remain in sync with the network.

It’s also important to remember that each node has a unique identifier attached to its device. This unique ID allows users to identify a specific node in a network. As keepers of records, nodes ensure that everyone can access a transaction record without any type of restriction. Users can easily track a transaction on the blockchain using its ID.

Overall, nodes are critical to a blockchain network because without them the blockchain would cease to exist.

Nodes help secure the blockchain by keeping the record in sync with the latest transactions. Due to a large number of nodes, it’s practically impossible for a hacker to make changes and remain undetected. The data is secure because a hacker cannot delete data copied across thousands of different nodes.

Power outages, hacks, and system crashes do not pose a threat because the data is not limited to any single node. In case of a problem, the availability of other nodes ensures that the network continues to operate as normal and users can access the required resources.

The blockchain network can also sustain itself in a global crisis. In fact, you only need one node to keep an entire blockchain operational. Even if every single node goes offline, you will need only one node to restore the entire network. From an operational perspective, nodes are the backbone of blockchain. Without a node, the network will not survive.

What Are the Types of Nodes on a Blockchain?

Blockchain networks may contain various types of nodes. These include full nodes, light nodes, supernodes and lightning nodes. (You will also come across other nodes, such as VeChain authority nodes, master nodes, pruned nodes and mining nodes.)

Here is a brief overview of some of the most important types of nodes:

Full nodes contain the complete history and information pertaining to every block since the first transaction took place on the platform. Full nodes form the backbone of a blockchain because they’re vital to completing the transaction. Whenever a transaction is initiated, every single node on the entire blockchain verifies and authenticates the block.

Needless to say, there is a lot of data on these nodes. To continually process such a vast amount of data, the node requires immense computing power. At any given time, a blockchain ecosystem may have thousands of full nodes working in tandem. These nodes have specific responsibilities that make them different from other nodes on the network.

One of their distinguishing features is validating the signature in each block transaction. To authenticate a transaction, the node verifies a digital signature. The digital signature is usually the private key used by the sender.

They also have the authority to accept or reject new blocks and transactions. There can be more than one reason to reject a transaction. Blocks that are incorrectly formatted will be rejected. Likewise, duplicate entries and manipulation in records are other reasons for rejection.

Running these nodes allows users to validate incoming transactions without waiting for others to validate them. In some cases, users validating incoming transactions are rewarded for their efforts.

As the name suggests, light nodes contain light or limited information. Instead of storing complete information, a light node contains information related to a particular previous block to which it’s connected. The information is stored 

Unlike some other nodes, light nodes don’t need to run continuously. They are usually pieces of software that connect to full nodes to access the blockchain when required. In fact, light nodes use full nodes as intermediaries to access the network. They also use full nodes to get information, such as the account balance and requesting the latest headers.

Due to their lightweight operations, these nodes don’t require a lot of storage and resources to run. You can run a light node on your mobile, because 100MB of storage space with low computational power is enough to justify its operations. Most light nodes can sync with the network in a matter of seconds.

Supernodes connect full nodes and help spread information across the network to ensure that everyone has accurate data. Supernodes handle off-chain functionality. They offer validation, authorization, gateway services and support. Besides their normal operations, they also facilitate voting events, compliance with blockchain laws and execution of protocol events.

Supernodes are generally always online. Unlike other nodes, they also require much more power and resources to run. 

 means that you have to deal with maintenance, electricity, storage space and memory. As a result of all this overhead, operators of supernodes are compensated in the form of tokens and coins.

Not everyone can run a supernode. Running a supernode requires an upfront investment in equipment and the provision of collateral in the form of cryptocurrency. The security deposit receives interest, but the collateral may be confiscated if you violate the rules of the blockchain.

. There are a few critical differences between traditional nodes and lightning nodes. Instead of verifying each transaction on the network, the lightning node validates the transaction by directly interacting with it.

Lightning nodes can also interact with other nodes on the peer-to-peer (P2P) network. The main function of this node is to exchange money with other lightning nodes.

Every transaction is added to the blockchain by a miner. Miners are also known as mining nodes. Every node on a blockchain has the option to become a miner.

There is a huge incentive to become a miner, by adding and verifying a transaction in a blockchain. For instance, any node that adds a transaction to the Bitcoin blockchain is rewarded with 6.25 bitcoins, valued at approximately $300,000 based on the Bitcoin rate of $48,000.

Due to this potentially lucrative opportunity, many miners want to add a transaction. Therefore, Bitcoin blockchain software offers a mathematical puzzle for every mining node to solve. Whoever solves the puzzle gets the opportunity to add the transaction.

Of course, it’s not quite that simple. But this example should provide you an overview of what mining nodes are, and why miners spend considerable time and energy to add transactions to the blockchain. It’s also important to remember that mining rewards differ, depending on the type of blockchain platform.

Bitcoin Nodes vs. Ethereum Nodes vs. Cardano Nodes

A Bitcoin node is a part of the Bitcoin blockchain. According to recent data, there are more than 11,500 Bitcoin nodes — and the number is increasing every month.

It’s important to note that there is no definitive method of counting the exact number of Bitcoin nodes, because many nodes are inactive, and a lot of these operate privately. Running a Bitcoin node can enhance security and bolster privacy.

Ethereum nodes are very similar to Bitcoin nodes. Experts estimate that the number of Ethereum nodes has exceeded that of Bitcoin nodes. Running an Ethereum node requires certain administrative skills.

You can run the node in fast, full or light mode. To run an Ethereum client on HDD (hard disk drive), you must have at least 8MB bandwidth, 4GB RAM and a CPU with 2 cores. By comparison, you may need less power to run a full Bitcoin node.

Cardano nodes are also gaining in popularity. These are the top-level nodes that underpin the Cardano network, whose topology is slightly different from Ethereum and Bitcoin because it doesn’t store a copy of transactions on each node. Instead, the system appoints a leader among a collection of nodes, which ultimately verifies and validates a transaction.

As you may have already guessed, running a node on different platforms has different procedures and system requirements. To make things easier, here’s a brief overview of how to run a node on one of the most popular blockchain networks, Bitcoin. This example will give you some idea of how the node is run on such platforms.

To run a Bitcoin node, you’ll need a laptop or desktop that is running a recent version of Windows, Mac OS X or Linux. The computer must have at least 2 GB of free disk space and 2 GB RAM. The system should have access to a broadband Internet connection with a speed of at least 400KB. In addition, you should let your node run at least six hours per day.

You can run the Bitcoin Core on your local machine that has the minimum requirements specified above. To do this, you’ll need to configure the Bitcoin Core client. It can take some days to sync with the blockchain.

Another option is to run the node in the cloud. After setting up an account with Google Cloud or AWS, download the Bitcoin Core and configure the port setting on your computer. There are various other methods to run a Bitcoin node, such as pre-configuring Bitcoin nodes that you can connect to your computer.

You can install the node yourself but technical difficulties can hamper your progress. One way to solve the problem is by getting assistance from a blockchain node provider. These blockchain-as-a-service companies offer the necessary infrastructure, resources and technology to run your node across a variety of platforms.

The provider handles all the responsibilities of the node. Based on your requirements, you can select a network of your choice to run a node.

When selecting a blockchain node provider, it’s necessary to consider the price of outsourcing the operation of a node compared to doing it yourself. You should ensure that the provider offers some kind of security guarantee — because a lapse in security can have serious financial consequences. Also, pay attention to the track record of the node provider and make sure that the service nicely integrates with your product.

Running a blockchain node is perhaps the only way to ensure that you have full control of your node and that you’re following the blockchain rules.

While running a node, it’s easy to create and broadcast transactions without compromising private information. Users can also improve security by keeping their private keys separated from external connections. Beginners and people new to running a node can choose a blockchain node provider to ensure that the entire process is user-friendly and less time-consuming.
