In –http endpoint auth=true may cause the problem to connect with Metamask.

Tech / By isti / January 20, 2025

In the context of an Ethereum node’s JSON-RPC interface, setting –http.server to auth=true means that you are enabling authentication for the HTTP-based JSON-RPC server. This means that when you send JSON-RPC requests to the node’s HTTP endpoint, you will need to provide valid credentials for authentication. Authentication is a security feature that helps protect the …

Zk-SNARKs in Substrate

Tech / By isti / July 26, 2024

zk-SNARKs in Substrate: Bringing Privacy to Custom Blockchains Zero-knowledge proofs are no longer just theory. They are becoming one of the most powerful tools for building privacy-preserving blockchain applications. Among them, zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge) are especially popular because they allow efficient verification of proofs without revealing sensitive data. On the other …

The Graph: Google for Blockchain Data

Tech / By isti / June 20, 2024

When you build on Ethereum or any blockchain, you quickly run into a problem: the data is there, but it’s buried in endless blocks and logs. Imagine trying to track every Uniswap trade by scanning the entire chain yourself. Painful, right? This is exactly why The Graph Protocol exists. It’s a decentralized way to index …

You may face the error: artifacts not finding in solidity. There are many solutions over internet but not for you. Here is my solution: just make smart contract name and solidity file name same. Yes! it is solved.

Reduce the computational cost of zkSNARKs:

Tech / By isti / October 25, 2023

In addition to these general techniques, there are also a number of specific zkSNARK constructions that have been designed to be more efficient. For example, the Groth16 zkSNARK construction is much more efficient than the original zkSNARK construction proposed by Gennaro, Gentry, and Parno. Another way to reduce the computational cost of zkSNARKs is to …

RemixIDE and Solidity Error- CompilerError: Stack too deep

Tech / By isti / August 29, 2023

Reasons: The “Stack too deep” error in Solidity often occurs when you have too many local variables, function parameters, or state variables in a single function or scope. Solidity has a limit on how many variables can be pushed onto the stack within a single frame of execution. To resolve this issue, you’ll need to …
