RPC stands for Remote Procedure Call, and it refers to a protocol that allows a computer program to request services from a server in a network. In the cryptocurrency sphere, RPC is commonly used for communication between client applications and blockchain nodes. An RPC node serves as an interface for developers to interact with the blockchain, allowing them to access its data and execute transactions. The RPC protocol provides a standardized way for clients to communicate with the node, allowing them to query the blockchain, submit transactions, and perform other operations. By using an RPC node, developers can build and deploy decentralized applications on networks like Ethereum.
RPC nodes can be divided into two main areas: shared or dedicated. Shared nodes are less secure and less reliable compared to dedicated nodes, but they are also less expensive and require less maintenance. However, dedicated nodes are the preferred choice for organizations requiring a high-security level, reliability, and performance. When working with dedicated RPC nodes, it's important to ensure that they are properly maintained and managed.
The maintenance of a dedicated Ethereum RPC node can be done in two ways: in-house or by outsourcing. In-house maintenance involves having a dedicated team responsible for managing the Ethereum node. This team is responsible for setting up, configuring, and maintaining the node, as well as troubleshooting any issues that may arise. This approach requires significant investment not only in hardware and software but also in terms of personnel and can be time-consuming and resource-intensive.
Outsourcing, on the other hand, involves contracting a specialized service provider to handle the maintenance and management of a node. This approach allows the organization to benefit from the expertise and resources of the service provider, who is responsible for ensuring the node is up-to-date, secure, and functioning properly. By outsourcing the RPC node maintenance we can reduce costs, improve security, and free up valuable time and resources that can be redirected to more critical tasks.
The following are some key benefits of outsourcing RPC node maintenance.
Maintaining an RPC node requires continuous monitoring and troubleshooting to ensure that the node is up-to-date and functioning properly. This can consume a significant amount of time and resources from a company's development and operations teams. By outsourcing this task to a specialized service provider, companies can free up valuable time and resources that can be redirected to more critical tasks.
Outsourcing the maintenance and management of Ethereum RPC nodes can provide a high level of reliability and security, ensuring that the node is always up-to-date, secure, and functioning properly. Service providers specializing in Ethereum RPC node maintenance offer expertise, round-the-clock monitoring, quick response times, and regular maintenance to minimize the risk of downtime and technical issues. By outsourcing, organizations can improve the reliability of their systems, reduce risk, and increase operational efficiency, leading to improved customer satisfaction.
In-house maintenance of an RPC node requires significant resources, including hardware, software, and personnel. By outsourcing it, companies can reduce their costs and minimize the need for expensive hardware and software investments. Additionally, they can avoid the cost of hiring and training employees to handle maintenance tasks.
For example, let's assume that an in-house DevOps engineer earns $100,000 per year, and it takes approximately 300 hours per year to maintain an Ethereum RPC node (research, updates, support, etc.). So the cost of in-house maintenance would be around $16500 for salary alone. RPC nodes also require servers to function. For an Ethereum RPC node, the price will be around $500 per month.
It turns out that the actual cost of supporting one node would be around $22500. This approach, however, won't provide you with the confidence that it will work properly around the clock. In most cases, one engineer cannot adequately cover all tasks, since failures and problems can occur at any time (at night, on holidays, etc.). For this reason, a 24/7 team is necessary.
Outsourcing Ethereum RPC node maintenance can provide a wide range of benefits, including saving time and resources, improved security, and reduced costs. By outsourcing this task to a professional service provider, companies can focus on their core business functions while ensuring that their RPC node is properly maintained and secure. This can result in significant cost savings and a more efficient use of resources.

We hypothesize that longer delays and higher transaction costs could be a sign of censorship.</p> <p>We hypothesize that our main metrics (delay and transaction costs) could be statistically different in the following subgroups:</p> <ul> <li>MEV-boost / non-MEV-boost</li> <li>Relays (OFAC-compliant/non-compliant)</li> <li>Lido validators versus others</li> </ul> <p>We also want to check the level of censorship employed by Lido validators so we are going to check the following hypothesis:</p> <ol> <li>MEV transactions may be under censorship and it can lead to a slowdown in operations compared to non-MEV.</li> <li>Delay and cost of transactions could be different between Lido validators and other validators.</li> <li>Relays that censor transactions can have a longer delay than other relays.</li> <li>OFAC-compliant relays could take longer to process transactions compared to other relays</li> <li>The probability of some transaction being included in the Nth block in the case of OFAC/not-OFAC could be different.</li> <li>The probability to be included in the OFAC block for Lido validators could be different, compared to non-Lido validators.</li> </ol> <h3 id="truncated-dataset-for-potentially-censored-transactions-a-namet5a">Truncated dataset for potentially censored transactions <a name="T5"></a></h3> <p>We want to highlight a certain amount of transactions whose high time delay could not be explained by normal network conditions. Such transactions will be suspect of being subject to censorship. To realise this, we must take into account the following transaction properties.</p> <p><strong>High delay</strong></p> <p>We will start by choosing all the transactions over a certain threshold for the time delay in seconds.</p> <p><strong>Successful transactions</strong></p> <p>Next, we will only consider successful transactions since failure could be a reason for the delay.</p> <p><strong>Low transaction fees</strong></p> <p>Another reason for a transaction to have a high delay could be low fees. That is why we should account for that and start by checking the transaction fee.</p> <p><strong>Previous transaction pending</strong></p> <p>Sometimes transactions could delayed simply because a previous transaction from the same sender had not yet finished. We use nonce parameters to exclude these transactions in our analysis.</p> <p>After forming the truncated dataset, we will try to find out the reasons for the high delay in censored transactions: government-driven or ethical censorship. We will check the receiver and sender addresses against the sanctioned list and share OFAC/ethical censoring MEV-relays.

<p>RPC nodes allow external applications to communicate with the blockchain network to execute commands or retrieve information. These nodes serve as a bridge between the blockchain network and external systems, enabling these external systems to interact with the blockchain. You can find a more detailed overview of this functionality at this link – <a href="https://p2p.org/economy/rpc-node/">https://p2p.org/economy/rpc-node/</a></p><p>In this article, we look at the differences between shared and dedicated nodes.</p><h3 id="shared-rpc-nodes">Shared RPC nodes</h3><p>Shared RPC nodes can be a cost-effective solution for accessing a blockchain network, as it eliminates the need for each user or application to set up and maintain its own node. The downside is that a shared RPC node may not be as performant as a dedicated node since the resources and processing power are shared among multiple users, leading to slower response times and lower overall productivity.</p><p>Shared nodes are often used by smaller organizations, developers, and individuals who need access to the blockchain, but do not have the resources to support a dedicated node. They are a cost-effective solution for those who need to make occasional or low-volume queries.</p><p>Advantages of a shared RPC node include:</p><ul><li>Lower maintenance costs: A shared node requires a smaller hardware and technical support investment, making it a more affordable option for organizations and individuals who need occasional or low-volume access to the blockchain.</li><li>Advanced Features: Some of these services may offer advanced features, such as data analytics and monitoring tools, making it easier to manage and monitor interactions with a blockchain network.</li><li>Fast Scalability: These services can scale to accommodate a large number of users or applications, making it possible to access the blockchain network at a large scale.</li></ul><p>However, it is important to note that shared nodes have some disadvantages, including:</p><ul><li>Reduced control over node configuration: Users have limited control over the configuration of their shared node, which may limit their ability to make changes to the node's settings, run custom scripts, and implement additional security measures.</li><li>Potential security risks: Sharing a server with other users increases the risk of potential security threats, as unauthorized access to the server could compromise the security of the node and its users.</li><li>Dependence on server provider: Shared nodes are dependent on the reliability and security of the shared server provider, which can be a concern for organizations and individuals who require a high level of security and control over their connection to the network.</li></ul><p>In conclusion, shared RPC nodes are a good choice for organizations and individuals who need occasional or low-volume access to the blockchain, and who have limited resources to support a dedicated node. These may include developers, small organizations, and individuals who need to build and test dApps or access data. In some cases, sharing a node is also an excellent choice for specific tasks that do not require a high level of performance. However, one should be aware of the potential security risks and limitations of using a shared node, and should carefully evaluate their needs and requirements before making a decision.</p><h3 id="dedicated-rpc-nodes">Dedicated RPC nodes</h3><p>Dedicated nodes are often used by organizations that require a higher level of security and control over their connection to the network. They are ideal for enterprise-level dApps, exchanges, wallet providers, and other organizations that need to access a blockchain network on a regular basis.</p><p>Advantages of a dedicated RPC node include:</p><ul><li>An unlimited number of requests: The main benefit of using a dedicated RPC node is the ability to handle unlimited requests, as the node is not shared among multiple users or applications. This allows the user to make as many requests as needed, without having to worry about the impact on other users or applications. This is particularly useful for applications or users with high volumes of requests, as it ensures that the requests can be processed quickly and efficiently, without the risk of slowing down or disrupting the network. Hardware is the only factor that limits performance. </li><li>Full control over node configuration: Users have complete control over the configuration of their dedicated node, including the ability to make changes to the node's settings, run custom scripts, and implement additional security measures.</li><li>High performance: Dedicated nodes have the processing power and memory necessary to handle high volumes of transactions and data. This is especially important for dApps and clients that require real-time data access and updates.</li></ul><p>However, it is important to note that dedicated nodes have some disadvantages, including:</p><ul><li>High maintenance costs: Maintaining a dedicated node requires ongoing investment in hardware and technical support, which can be a significant cost for some organizations.</li><li>Complexity: Setting up and configuring a dedicated node can be complex, requiring a high level of technical expertise.</li></ul><p>In conclusion, dedicated RPC nodes are a good choice for organizations that require a high level of security and control over their connection to the network, and that have the resources to support the ongoing maintenance and storage requirements of a full node. These may include enterprise-level dApps, exchanges, wallet providers, and other organizations that need regular access to the blockchain.</p><p>Nevertheless, maintaining the nodes yourself may not always be necessary. It is possible to order a dedicated RPC node service from third-party contractors, who specialize in providing blockchain infrastructure and support services. These contractors can set up and maintain a dedicated node on behalf of the user, offering a more convenient and cost-effective solution compared to setting up and maintaining a node in-house. Third-party contractors typically have the technical expertise and resources to manage and maintain dedicated nodes, providing a high level of reliability and performance. This can be an attractive option for organizations or individuals who want the benefits of a dedicated node but lack the resources or expertise to set one up themselves.</p><h3 id="conclusion">Conclusion</h3><p>In complex projects, both shared and dedicated RPC nodes can be used in combination, depending on the specific needs and requirements. For example, a shared node could be used for general-purpose requests, while a dedicated node could be used for more resource-intensive tasks or for handling high volumes of requests. This approach allows organizations or individuals to balance the benefits of shared nodes, such as accessibility and affordability, with the benefits of dedicated nodes, such as reliability and performance. By using a combination of both shared and dedicated nodes, organizations can create a scalable and flexible infrastructure that can meet the demands of their project and evolve as the project grows and changes over time.</p><p>It is important to seek advice from professionals when designing and implementing an RPC infrastructure, as they can help to ensure that the right solution is chosen. Professional consultants can help organizations or individuals understand the different options available, including shared and dedicated nodes, and can recommend the best solution based on factors such as cost, performance, scalability, and security. By working with professionals, organizations can avoid making costly mistakes and ensure that their infrastructure is set up correctly, which can save time and money in the long run. </p><p>P2P offers support in setting up or maintaining your Web3 infrastructure.
