Day 18 – Dissecting the Go-Ethereum keystore files using Raku tools

Generally the Ethereum (Web3) keystore file is a kind of container for the private key, it has the specific structure mostly related to encryption details. Actually you will not find the private key there as a plain text, but the keystore file has everything to decrypt the private key… with some tricks surely. When youContinue reading “Day 18 – Dissecting the Go-Ethereum keystore files using Raku tools”

Day 14: Trove – yet another TAP harness

Since the early Pheix versions, I have paid a lot of attention to testing system. Initially it was a set of unit tests – I tried to cover a huge range of units like classes, methods, subroutines and conditions. In some cases I have combined unit and functional testing within one .t file, like it’sContinue reading “Day 14: Trove – yet another TAP harness”

Day 12 – A long journey to Ethereum signatures

The Ethereum blockchain is essentially a transaction-based state machine. We begin with a blank state, before any transactions have happened on the network, and move into some final state when transactions are executed. The state of Ethereum relies on past transactions. These transactions are grouped into blocks and each block is chained together with itsContinue reading “Day 12 – A long journey to Ethereum signatures”

Day 8: Raku web templating engines: boost up the parsing performance

Modern Raku web templating engines A templating engine basically provides tools for effective metadata interpolation inside static files (templates). At web application runtime, the engine parses and replaces variables with actual content values. Finally client gets a HTML page generated from the template, where all metadata (variables, statements, expressions) has been processed. Raku ecosystem hasContinue reading “Day 8: Raku web templating engines: boost up the parsing performance”
