Q1. What is Ethereum Virtual Machine (EVM)? The Ethereum Virtual Machine or EVM is the runtime environment for smart contracts in Ethereum. It is not only sandboxed but actually completely isolated, which means that code running inside the EVM has no access to network, filesystem or other processes. …

Blockchain is an immutable public ledger that securely stores data or information, making it less susceptible to hacking or modification. It is a decentralized/distributed digital transaction ledger devoid of central governance or a third party. It protects data by distributing it across all nodes in its ecosystem. When blockchain came…

Learn how to create a smart contract instruction on Solana that deposits tokens from one account to another — gm gm, I’m 0xksure and I write mostly about rust development and solana (usually with the anchor framework) development. I have a lot of experience in backend development, but have also done my fair share of frontend work and general sdk work using typescript. …

In part 1 of this series we saw how to create a React+Typescript front-end that connects to the Phantom wallet and retrieves our public address. In case you need, here are the links to the articles in this series: Part 1: Connecting to the Phantom Wallet Part 2: Requesting an airdrop…

In April, our vulnerability detection system discovered an issue in the rBPF of Solana (i.e., the virtual machine where all the Solana dApps are running on: https://github.com/solana-labs/rbpf). After a careful investigation, we found that it is a security vulnerability that can lead to a wrong execution path of a contract…
