How to setup a IPFS network in Ubuntu

Welcome again developers,


In this article we will see how to setup IPFS network in an Ubuntu machine/System. we will go step by step in this article if you did not saw our Intro to IPFS we recommend  to see this first.
In this we setup a public IPFS network.


step 1. Install go


 * download go zip file from there official website https://golang.org/dl/ 













* Create a new folder, then copy the downloaded file into this folder.


















 * open terminal in current directory ("the directory which we created 'work folder' ")


* type "  sudo tar -C /usr/local -xzf go1.12.7.linux-amd64.tar.gz  " : this command will extract the file into the /usr/local folder, Note: in our case we have go1.12.7.linux-amd64.tar.gz file if you have any different version then use that file name instead of go1.12.7.linux-amd64.tar.gz.


* type  "  export PATH=$PATH:/usr/local/go/bin  " : the export command marks an environment variable to be exported with any newly forked child processes, in this line $PATH variable will be updated with new value /usr/local/go/bin/ .


* type "  source $HOME/.profile  " : source command will bring the given file into the shell script , in this .profile will be loaded in current shell script .


* type " go version  " :  to check the go version.






step 2 : Install IPFS


* open terminal in current directory " work folder ".


* type " sudo apt-get update ".




* go to official website of IPFS by clicking here then right click on download button and copy the address .


* in terminal type "  wget  paste_the_copied_URL  " : this will download a zip file in current directory.



* type " ls " to see the downloaded file.


* type " tar xvfz downloaded_file_name " : this will unzip file.








* type " sudo  mv  go-ipfs/ipfs  /usr/local/bin/ipfs " : this command will move the ipfs file from current directory to /usr/local/bin/ipfs.


* clean unnecessary files and folders : type : " sudo rm -rf go-ipfs " .


* type : " ipfs version  " : for checking the ipfs version installed .



* type : " ipfs init " :  we need to initialize the ipfs file, it required once at the time of installation after this we not need to run this command again. This command will return a peer ID which is a unique identification of each peer.








step 3 : establishing network and deploying file to it.



* create a folder( "project" ) then create a new text file ("first.txt") in the folder save the text file with some content ( "hello world").







* open two terminals in current directory



* in first terminal type " ipfs daemon " : it will start a thread process  to provide a ipfs gateway for accessing/deploying yours file over the network. leave this terminal as it is.






* in 2nd terminal type : " ifps swarm peers " : this command will list all the peers you connected with through internet.






* type : " ls "  check your file in your current folder.


* type " ipfs add filename.extensionName " eg . " ipfs add first.txt " :

this will add file to the ipfs network and return the hash value for accessing this file data.


a*  copy the returned hash value and type : " ipfs cat paste_hash " : this will output the content of file .




b* publish your file over the network : type : " ipfs name publish paste_hash" : this will publish your file over the network and return a string like this "ipfs/your_hash_value" then copy this value.




c* open your browser and type " localhost:8080/paste_value_here" eg : 'localhost:8080/ipfs/hashValue'


--------------------------------------------------------------------------------------------------------------------

* instead of a file if you want to add a whole folder then follow the following commands .


* navigate to your folder parent directory through terminal , type : " ls  " to see your folder.


* type :   " ipfs add -r folderName " : this will recursively add your folder to the ipfs. It will return the bunch of hashes according to number of file in the folder , just copy the last hash it is the hash of root folder then follow the  a*, b* and c* steps.

Private network in IPFS

Welcome again developers, In this article we will see how to setup a private  IPFS network in an Ubuntu machine/System. we will go step by step in this article if you did not saw our Intro to IPFS   and  public IPFS network   we recommend  to see this first. In this we setup a private IPFS network. Note :            * for this we need two ubuntu system connected to a same network (LAN/WiFi).            * select one system as a bootstrap node and another as client node.            *follow step 1 and step 2 in both the system as it is. step 1. Install go  * download go zip file from there official website https://golang.org/dl/  * Create a new folder, then copy the downloaded file into this folder.  * open terminal in current directory ("the directory which we created ...

Intro to IPFS

IPFS stands for InterPlanetary File System, It is used to store files in a distributed decentralized manner, following points are helpful in understanding IPFS. FEATURES  1. IPFS is content addressable : IPFS protocol finds data by using content address instead of path address, whenever any data is published to IPFS it will return the hash of the content (like this /ipfs/mQy76CQGy9NdmqEnnHU9soCexBnGU3ezPHVH) , if we talk about centralized approach  we will get a path like  " https://www.domainName.com/yourData ". In centralized approach we can get data using the URl and in IPFS we can get data using the hash .   2. IPFS is peer-to-peer connection :  IPFS is same as world wide web but in this a peer can connect to another peer directly, there is no need of any centralized node. 3. IPFS gateway : IPFS can be access over the HTTP protocol we can make our own gateway or we can use another gateway like infura . In our local system i...
