Internet Magnets 5 - Lighthouses and Messages (Personal, Public, and Updates)

I remembered that I did not tell an important part to ensure the possibility of communication and updating content in P2P networks.

Not all P2P networks have the ability to send and receive private messages. Also, not always the message can be left offline. We will correct this shortcoming using three features of P2P networks: search for a file, view balls (a list of published files) or comments to a file.

How it works

The lighthouse template is created once and used to create lighthouses for communication with the author.

General receipt algorithm

A lighthouse pattern is published.
A lighthouse is being formed.
Search for this beacon and the file with the beacon hash in the name.
Download found files or view balls of lighthouse sources.

The general algorithm for sending such

We write the message.
We encrypt the recipient's public key.
We form a beacon on the addressee pattern.
We receive a hash from a beacon and we interpose into a file name with the message.
We publish a beacon and a file with a message in p2p networks.

Our message and the beacon are free to copy other members of the network. Since it is encrypted, they will not be able to read it, but will help keep it online until the addressee receives it.

Open message from the author

Publish the pattern of the lighthouse.
We write the message and we sign.
We generate a beacon.
Enter the beacon hash into the name of the message file.
We publish the beacon and the file with the message.

Lighthouse pattern

This is the file from which the beacon is formed.

The lighthouse template is created by the one who wants to receive messages (addressee) and publishes in his balloon or a comment with a magnet to another lighthouse. The template should include

Public key to encrypt messages destined to the addressee
Lighthouse Template - instructions for forming a lighthouse
Signature - the file is signed.

Template instructions should allow generating files with identical hashes (beacons) every hour or another selected period of time.

Creating a beacon pattern

We get the fingerprint of the public key.
```
gpg --list-sigs --with-fingerprint 
```

Exporting public key

 gpg --export -a > lighthouse_template_[  ].txt

Open the file ( lighthouse_template_[ ].txt ) and add the instruction.
Example:

yyyy - full year UTC ± 0: 00
mm - month UTC ± 0: 00 (supplemented with zero if less than 10)
dd - day on time UTC ± 0: 00 (supplemented with zero if less than 10)
hh - hour in 24 hour time format UTC ± 0: 00 (complemented by zero if less than 10)

Beacon file name template (important for BitTorrent network):
lighthouse_yyyy-mm-ddThhZ_[ ].asc

To form a beacon, add a date and time at the end of the file in the format:
yyyy-mm-ddThhZ

Signing.

 gpg --clearsign lighthouse_template_[  ].txt

Lighthouse

The lighthouse is formed from the lighthouse template according to the instructions given in it. First, the template itself goes unchanged and then there is data that is formed according to the instructions from the template.

The task of the lighthouse is that both the sender and receiver can form the same lighthouse (with the same hash) and find each other or the intermediary who stores the message using the hash.

Lighthouse example

The lighthouse on June 9, 2017 18:33 Moscow will look like this.

Accordingly, every hour a new lighthouse is created.

Each P2P network uses its corresponding hash.

Search for files by the beacon hash allows you to send an open message in the name of the beacon file. (Gnutella2, DirectConnect, Edonkey2000, IPFS)

Searching using a hash as part of the file name will allow you to transfer the file. This can be a private message encrypted with a public key from a beacon. (Gnutella2, DirectConnect, Edonkey2000, IPFS)

Comments to the beacon file can also be used. They can have a message or a magnet on a file with a private message. (Gnutella2)

IPFS

For the IPFS network, it is necessary to find the sources of the beacon and obtain source-related files / directories using the sources' public keys. Next on the list, find the beacon itself or the file / directory with the beacon hash in the name.

Get a list of peers with a beacon:

 ipfs dht findprovs [ ]

The result will be multi-peaks of public keys of peers with a beacon

We get multihash balls:

 ipfs name resolve [  ]

Result / ipfs / path with multihash related file or directory

We are looking for a beacon and a file with a beacon hash in the name:

 ipfs refs -r --format="<dst> <linkname>" [ ]| grep "[ ]"

As a result, we get the messages:

 [ ] [    ] [ ] [       ]

In the second case, the message is the contents of the file.

Load the command:

 ipfs get [ ]

Edonkey2000, DirectConnect, Gnutella (1,2)

These networks allow searching by hash and file name. So it is enough to use the hash as a name or to search for the beacon itself according to the hash and look at the sources' ball.

Gnutella2

In this network, it is possible to comment on file sources. In this case, it is enough to search for a beacon by hash and look at the comments on the results. Or you can also search using a hash as part of the file name.

Bittorrent

Not yet invented. The ability to comment on the distribution was removed from uTorrent .

There is an idea to generate a large beacon and by mashing the parts to form a barcode from which you can get a hash of the new message.

The second option is to create a set of lighthouses and then the presence on the distribution will be 1 and the absence of 0. Part of the lighthouses will encode the hash and the other part of the checksum.
