Blockchain-based Service Network



RPC

RPC(Remote Procedure Call) is a set of protocols and interfaces that the client interacts with blockchain system. The user can query the blockchain related information (such as block number, blocks, node connection, etc.) and send the transaction request through RPC interface.


RPC nodes provide a link between blockchains and the decentralized applications (dApps) that run on top of them. Web3 wallets have default RPC node providers so users can easily start interacting with web3 applications, however, sometimes these default, public RPC nodes cause problems for everyday users and web3 developers due to slow network speeds, incorrect blockchain data, and unreliable service (uptime).

In this article we’re going to explain why it is a good idea to create a private RPC endpoint, and how to add one to your MetaMask wallet so you can get faster speeds, accurate data, and more reliable service.

In the context of this article, the term “private RPC endpoint” means a personal RPC endpoint that is not publicly available for everyone else to use. We do not mean that the transactions sent through your personal RPC endpoint are private transactions, that they will settle privately, or that they will not appear in the public mempool.


What are the benefits of using a private RPC endpoint ?


Using a private RPC endpoint has many benefits including speed, accurate data, more reliable service, and less competition when submitting transactions during periods of high transaction volumes like an exclusive NFT drop.

Here are some of the use cases where traders, developers, and everyday users could benefit from updating their MetaMask wallet from the default RPC endpoint to a personal one:


  • Sending transactions during an exclusive, first-come-first-serve NFT mint.


  • Sending transactions to capitalize on time-sensitive arbitrage opportunities.


  • Getting reliable service when other node providers experience degraded service during airdrops.


There are multiple reasons why web3 users stand to benefit from creating a private RPC endpoint and updating their default web3 wallet settings to send transactions through a personal RPC endpoint.

A Security Analysis of Blockchain-Based Did Services

May 22, 2022
Decentralized identifiers (DID) has shown great potential for sharing user identities across different domains and services without compromising user privacy. DID is designed to enable the minimum disclosure of the proof from a user's credentials on a need-to-know basis with a contextualized delegation. At first glance, DID appears to be well-suited for this purpose. However, the overall security of DID has not been thoroughly examined. In this paper, we systemically explore key components of DID systems and analyze their possible vulnerabilities when deployed. First, we analyze the data flow between DID system components and analyze possible security threats. Next, we carefully identify potential security threats over seven different DID functional domains, ranging from user wallet to universal resolver. Lastly, we discuss the possible countermeasures against the security threats we identified.
