The purpose of this configuration is to generate a Docker environment of 2 nodes connected together running on Geth and monitor them using Ethstat (at localhost:3000). Then we can use MetaMask as well as Remix to connect to the first node (localhost:8545) to send simple transtractions, like sending Ether, or complex transactions like the creation or call of a smart contract.
Following our Smart Contract Auditing: Human vs. Machine article, we now analyze Slither, which is another static analysis tool from
These last years there has been growth in Smart Contracts development, predominantly in the Ethereum blockchain. Ethereum, being a different type of blockchain than Bitcoin, can execute concise lines of code inside its chain, a job that Bitcoin (specifically designed to send transactions easily) can’t do. Here is where RSK intervenes building a sidechain tied up to Bitcoin through a 2-Way Peg system, managed by the Federation Partners, that makes code execution possible. Instead of designing a new programming language for developing Smart-Contracts, they used Solidity, the same language that Ethereum uses. This has two benefits: not only programmers won’t have to learn a new skill but also contracts in the Ethereum network could be deployed in RSK without much effort, taking advantage of the vast market capitalization Bitcoin has.
Coinfabrik was asked to audit the smart contracts for the Send Token sale. In the first part, we will give a summary of our discoveries and follow them with the details of our findings.
Send (SDT) is making an ICO to create a 7-day price-stable crypto token that discovers a new market price once a week.
Solidity semantics are confusing for smart contract developers with experience in traditional programming languages. This semantics can lead to security
We describe a geth source code change which enables faster block mining. We hope this option will be included in
Working for our customers in our blockchain development company we built this spreadsheet which is a work in progress, comments are
