Bitcoin Core Review

Bitcoin Core can be used as a desktop client for regular payments or as a server utility for merchants and other payment services.

Versions of wallet

Bitcoin 0.1 was released on 9 January 2009 by Satoshi Nakamoto with only Windows supported. This was followed by some minor bug fixing versions. On 16 December 2009 Bitcoin 0.2 was released. It included a Linux version for the first time and made use of multi-core processors for mining. In version 0.3.2 Nakamoto included checkpoints as a safeguard. After the release of version 0.3.9 Satoshi Nakamoto left the project and shortly after stopped communicating on online forums. By this time development of the software was being undertaken by a wide group of independent developers which is referred to as a community, many of whom had various ideas on how to improve bitcoin.

  • Introduction of a new generation anonymous interface (REST standard).
  • Improving the security of operations. The place of outdated OpenSSL came the modern system of saving data Libsecp256k.
  • There are more convenient view. It is possible to view the wallet of another person and be aware of their operations;
  • Developed and installed a library of approvals, which allowed to improve the interaction of bitcoin with other software;
  • There is a system that opens up new opportunities in the field of operations management. This, in turn, speeds up the process of transactions in the network;
  • Work continues on the division of one core into several different utilities with a narrow specialization.

Bitcoin Core Blockchain

The original creator of the bitcoin client has described their approach to the software’s authorship as it being written first to prove to themselves that the concept of purely peer-to-peer electronic cash was valid and that a paper with solutions could be written. While the majority of peers on the network may use Bitcoin Core, the developers’ influence on bitcoin is limited by the choice of which implementation people voluntarily decide to use. The lead developer is Wladimir J. van der Laan, who took over the role on 8 April 2014. Gavin Andresen was the former lead maintainer for the software client. Andresen left the role of lead developer for bitcoin to work on the strategic development of its technology. He left because he didn’t want to get involved with trivial decision-making.

Bitcoin Core wallet features

Bitcoin Core includes a transaction verification engine and connects to the bitcoin network as a full Bitcoin Core node. Moreover, a cryptocurrency wallet, which can be used to transfer funds, is included by default. The wallet allows for the sending and receiving of bitcoins. It does not facilitate the buying or selling of bitcoin. It allows users to generate QR codes to receive payment.

  • Compatibility with Linux (both GNOME and KDE), Mac OS X and Windows
  • All functionality of the original wxWidgets client
  • Asks for confirmation before sending coins
  • CSV export of transactions
  • Clearer transaction list with status icons and real-time filtering
  • Progress bar on initial block download
  • Languages: Dutch, English, German, Chinese and many more. Translations are being done by volunteers on Transifex.
  • Sendmany support in UI (send to multiple recipients in one transaction)
  • Multiple unit support, can show subdivided bitcoins (mBTC, µBTC) for users that like large numbers (only decimal units)
  • Splash screen that details progress
  • Debug window
  • Payment requests (BIP 70)
  • Coin control
  • bitcoin-cli as a RPC client, instead of bitcoind executable functioning both as a server and as a RPC client

Sync time

Bitcoin Core is often criticized for being slow in downloading and verifying the Bitcoin transaction database (the blockchain). The download may be quicker using the bootstrap method. NOTE: As of version 0.10.0 it is now slower to download the blockchain via the torrent than it is to download the full blockchain through the P2P client.

Bandwidth use

It has also been criticized for “hogging” upload bandwidth when peers connect to download the blockchain (possible only when run with port 8333 accessible to outside connections). This perceived “issue” has been discussed extensively on GitHub. Most modern routers support quality-of-service that can be configured to properly share the internet connection across all services, and even deprioritise Bitcoin traffic. Bitcoin Core includes a script for Linux to configure QoS on an individual host. Windows users can also use third-party software such as Netbalancer to throttle the application’s upload bandwidth and ensure that one has enough upload bandwidth available for regular computer and internet use to be unaffected.

  • Requires a very long synchronization wallet;
  • Bitcoin Core has special requirements for PC hardware;
  • A fully loaded Bitcoin Core client weighs about 92 gigabytes, so you’ll need a lot of free space on the hard drive.

Lack of multiwallet support; node+wallet tied together

Wallet management is also cumbersome. Unlike clients such as Armory, MultiBit, Electrum and others only one wallet at a time is supported, and its location is required to be the same as the blockchain storage, making it difficult to place the wallet on an encrypted drive. It is recommended to backup the wallet.dat file every 50 transactions, due to the way Bitcoin Core handles change.

Bitcoin Improvement Proposals

A Bitcoin Improvement Proposal (BIP) is a design document, typically describing a new feature for Bitcoin with a concise technical specification of the feature and the rationale for it. This is broadly similar to the way in which Internet “Request for Comments” (RFCs) and the Python computer language’s “Python Enhancement Proposals” (PEPs) are used.
