Installation Bitcoin core on UBuntu 18.0.4 LTS : Bitcoin Mechanics -1

With this first post special to Bitcoin core,over next few months I intend to do some exploring on the bitcoin mechanics part.This basically means playing with the blocks and blockchain vide few python based scripts.Will start from the installation part followed by other posts on extracting info from bitcoin blockchain. This post basically is straight forward installation with the following commands.Screen shots for info :

Firstly install snapd with the following commands

sudo apt update
sudo apt install snapd

goto https://snapcraft.io/bitcoin-core

 

 click green button install

after this installation of snapd,one single command as follows:

sudo snap install bitcoin-core

The effected screenshots are seen below :

Once installed ,you can check on the terminal...should see three bitcoin applications by tabbing

While the GUI shows as below

When you run for the first time,the GUI notification pops for asking for location of default directory for storing blocks.

Thereafter the blocks start getting downloaded with status of files downloaded visible....

Blocks downloaded status is seen below...this downloading around 287 GB as on date will take time as per download speed available.

The location of the blocks being downloaded will be at /home/bitcoin_scripts/snap/bitcoin-core/common/.bitcoin/blocks where bitcoin_scripts is the user name.

Next post we will see whats inside the block....

BOILERPLATE : What does this mean in the computing context?

Well,this is going to be a short post about a general info of what Boiler plates means in the computing context.Recently I came across this term for the first time as I read this paper "SHOULD CODE BE LAW? SMART CONTRACTS, BLOCKCHAIN, AND BOILERPLATE" by Jeff Lingwall and Ramya Mogallapu. Then further exploring about this term simply refers to sections of code that have to be included in many places with little or no alteration. It is often used when referring to languages that are considered verbose, i.e. the programmer must write a lot of code to do minimal jobs.

More simply  : Any routine contract document would invariably be similar for most of its part except for the names and date changes.This similar part is the Boilerplate meaning it’s the same for everyone who gets that contract, with only a few changes.
