In the Technical section you’ll find beginner level articles about specific software components, programming concepts, cryptography and other pieces that make up cryptocurrency systems.
We also try to cover new tech and interesting concepts that you might come across in the crypto scene.
Understand the Double Spending problem
As implied by the name, a double spending problem happens when a transaction is processed twice while your account balance is only subtracted once.
This, of course, can only h...
Why the “fast” Ethereum sync is so slow
Why is the geth sync so slow?
I keep hearing this question again and again from Ethereum node operators. Why is it still so difficult to fully sync an Ethereum full node?
About Ethereum EVM’s high GAS cost
As cryptocurrencies mature, the promise of a worldwide distributed ledger and computing platform is now taken for granted by businesses around the world.
Billions of dollars we...
What are the limits of Bitcoin?
Bitcoin is a P2P network and, as such, faces limitations inherent to the underlying networks as well as the limitations of its own protocol. In this article we take a look at the ...
Bitcoin Toolbox Home
Crypto.BI Toolbox is a set of tools for local blockchain exploration. It uses data from the raw Bitcoin block data files and does not require a network connection, API’s and other 3rd party data sources. It’s built of a combination of C++ libraries, Python integration and many other planned components that aim to make blockchain […]
Bitcoin Blockchain to MySQL Insertion Tool
Crypto.BI Toolbox comes with a raw .dat block file to MySQL insertion tool called blocks_inserter. To use it, first you’ll need to generate the MySQL schema on your local server by importing scripts/sql/mysql/cryptobitoolbox_bitcoin.sql into your MySQL server. Then you will need to configure Toolbox with the appropriate username, password, host and database so that Toolbox […]
C++ Bitcoin Blockchain to MySQL Database Interface
Crypto.BI Toolbox abstracts database access through a thin database access layer. Every database operation required to run the system has been made into a separate function in db/dao/CBDAODriver.h This traditional approach, used in many system architectures, allows us to switch storage solutions by creating new subclasses of CBDAODriver. For instance, if a graph database was […]
Bitcoin Blockchain MySQL Database Inserter Configuration
Toolbox tries to read configuration from $HOME/.cyptobi/cryptobi.conf If a config file is unavailable, then defaults will be applied. The order of precendence from highest to lowest is: Command line options override all others. Config file options override defaults. Program defaults. Environment Set CRYPTOBI_HOME environment variable to the directory where you cloned the Crypto.BI Toolbox from […]
Concepts In This Page
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.
Block Sync is the procedure by which a cryptocurrency node retrieves validated block data from P2P peers on the network. A full node may only verify the most recent transactions once it finishes the block sync to the latest block.
Ticker symbol for the Ethereum cryptocurrency.
Ethereum is a second generation cryptocurrency, best known for making Smart Contracts available to the masses.
Geth is the reference Ethereum implementation. It is written using the Go programming language, thus the G prefix.
A networking architecture where peers talk directly with each other, not using a central server or infrastructure. E.g. Bitcoin and Bit Torrent are P2P systems.
EVM is an acronym for Ethereum Virtual Machine, the decentralized virtual machine which runs smart contract applications stored on the Ethereum blockchain.
Smart Contracts is self-enforcing business logic hosted on blockchains. Smart contracts are trustless, in that they carry out their specified instructions unconditionally.
Solidity is a smart contract programming language. It gained widespread adoption via the Ethereum Virtual Machine.
