Understand the Double Spending problem
As the name implies, the double spending problem consists in executing a transaction twice while subtracting once from your balance.
This, of course, can only happen by means ...

ELI5 How AVAX validation works [Avalanche Protocol]
According to the Avalanche AVAX token distribution policy, almost 50% of all AVAX in existence will go towards validator rewards (see chart at the top). Since the Avalanche protocol burns all fees, the only source of inflation in the AVAX ecosystem is the validation reward. This presents a great opportunity for those who join the […]
cavax – Experimental C language tools for AVAX Avalanche exploration
cavax is an experimental implementation of C language utils for the exploration of the Avalanche AVAX protocol. Initially, cavax supports limited networking and basic passive functionality (e.g. it does not actively verify vertices). cavax listens to the Avalanche network and calls hooks that you can set up to handle each message type. Some default hooks […]
Bitcoin Blockchain SQL Schema for MySQL
This SQL schema was created for Crypto.BI Toolbox. The same, or similar, SQL schema can be used by anyone exploring Bitcoin with the help of a MySQL RDBMS. Although we didn’t test this SQL with other RDBMS’, it should be fully compatible with MariaDB and any other MySQL-derived system. How the data is inserted/retrieved to/from […]
256 Bit Integer commented uint256.cpp from Bitcoin Core source code
If you’ve developed systems in C or C++ before then you’re probably familiar with the stdint.h (cstdint for C++) typedefs. Since there’a lot of variation between platforms, stdint.h standardizes integer type names in an intuitive way. A uint8_t is an 8-bit unsigned integer and a uint64_t is a 64 bit unsigned integer. What you won’t […]

Double spending is a condition where the same value can be spent twice, revealing a flaw in the payment processing system.
Irreversible transactions are a characteristic of digital payment systems which offer trustless decentralization. The irreversibility is necessary in order to guarantee that no transaction will be undone once committed by the network.
Cryptocurrencies have sparked renewed interest in the search for sustainable energy sources, including hydro mining and solar power.
Hydromining is the practice of using water to generate electrical energy required for cryptocurrency mining.
Avalanche is a consensus protocol introduced by Rocket Team in 2018.
It is an entirely new consensus protocol which builds upon classic consensus and Nakamoto consensus.
