Summary

Blockchain gateways are fundamental to achieving interoperability in the blockchain space. The safety of footbridges is therefore of paramount importance. Some of the most common gateway security vulnerabilities include weak validation on and off the blockchain, poor management of native tokens, and misconfigurations. It is recommended to test the gateway against all possible attack vectors to ensure strong verification logic.

Résumé

Formal verification of smart contracts ensures that they are free of bugs, vulnerabilities, and other unintended behavior. This involves a human expert presenting the logic of the smart contract in the form of mathematical statements, then running them through an automated process that checks the actual logic against models of the contract's expected behavior. The combination of formal verification and manual auditing provides a comprehensive assessment of the security of a smart contract.

SocialFi combines the principles of decentralized finance with social networks. It empowers content creators by giving them control of their data and allowing them to interact directly with their users.

Key features include tokenized social capital, blockchain-based data storage, and governance through decentralized autonomous organizations (DAOs).

To achieve mainstream adoption, SocialFi platforms must overcome two major challenges: scalability and economic sustainability.

Summary

The world of crypto and blockchain can be intimidating for novices. The ever-changing nature of blockchain and the sheer amount of information often overwhelm beginners. Finding a community of like-minded people can be a great way to get started in the crypto space.

Introduction

Web3 is a term describing the next iteration of the World Wide Web.
