I am happy to announce the finishing of the first edition of my Antelope Smart Contract Developer’s Handbook. This book summarizes my experience working with EOSIO/Antelope blockchain software in the past five years. The book is targeting experienced software developers who have started working with the blockchain technology that is serving such high-speed public blockchains as EOS, Telos, WAX, Proton, and a few others.

Mandel is the new code name of EOSIO software release, after its development was taken over from Block One by EOS Network Foundation. The global upgrade of EOS mainnet is planned for September 21st 2022. The Mandel software is compatible with Ubuntu versions 18.04, 20.04, and 22.04. Here I tested and described the package build procedure for generic EOSIO and WAX-specific node software: https://gist.github.com/cc32d9/786f45f0f502224155edc622dc83d79d

Pomelo is a grant matching platform for public good projects. This season is backed by a pool worth more than $900k, and the voting ends in about two weeks. Every small contribution counts, and the projects with higher participant counts are rewarded better. I’m applying for two grants this time: Sponsorship for bdata.one hosting (EOS Big Data) Writing a book for EOSIO contract developers (EOSIO Contract Developer Cookbook)

As some of you may know, I’ve been working on EOSIO history processing since summer 2018. A lot has been done in order to be able to extract the data from a fast blockchain like EOS with its enormous speed and load. About two years ago, I started collecting daily…

Pomelo is a new grant allocation platform on EOS mainnet, launched just a couple of weeks ago. It just boomed with a bunch of awesome projects in a matter of a few days. Every vote matters. Please send, even a tiny amount will make a difference in quadratic voting. My…

In my previous post I described the approach that we’re using on our production servers: physical RAM is larger than WAX state size, and the nodeos state is stored in a tmpfs partition. But WAX RAM consumption is growing quite fast: thousands of new accounts are created daily, and thriving…

Recent hack of EOSX Vault has added one more item to a standard security checklist in smart contract auditing. It makes sense to describe them all in one post. 1. Check the token contract Older CDT versions did not offer a nice wrapper for apply() handler, so the contract authors needed to pay more attention…

The WAX blockchain has grown in usage and size pretty dramatically. On May 8th 2021, 307k unique accounts have executed 51 million actions. On February 8th, it was 18k and 6 million, correspondingly. Back in February, a typical nodeos setup would include a baremetal server with 3.5Ghz or faster Intel…

It’s a common struggle for every dapp builder that transactions may disappear from the blockchain while their blocks are not final. A microfork, resulting in a few blocks reevaluated and newly signed, might not include the transaction you’ve already seen. …
