+
+* Introduction
+:PROPERTIES:
+:CUSTOM_ID: chapter1-introduction
+:END:
+This project focuses on creating a framework for running heavy computational tasks that a regular 
+computer cannot handle easily. These tasks may include graphically demanding video games, rendering 
+3D animations, and performing complex protein folding simulations. The major focus of this project 
+is not on financial incentives but rather on building a robust and efficient peer-to-peer (P2P) 
+network to decentralise task execution and increase the computational bandwidth available for 
+such tasks.
+
+The P2PRC framework serves as a foundation for decentralised rendering and computation, 
+providing insights into how tasks can be distributed efficiently across a network of peers. 
+Leveraging the P2PRC approach, this project extends its capabilities to handle a 
+wider range of computationally intensive tasks.
+
+** Motivation
+:PROPERTIES:
+:CUSTOM_ID: motivation
+:END:
+Many of the users rely on our PC / Laptop or servers that belong to a
+server farm to run heavy tasks and with the demand of high creativity
+requires higher computing power. Buying a powerful computer every few
+years to run a bunch of heavy tasks which are not executed as frequently
+to reap the benefits can be inefficient utilization of hardware. On the
+other end, renting servers to run these heavy tasks can be really
+useful. Ethically speaking this is leading to monopolisation of
+computing power similar to what is happening in the web server area. By
+using peer to peer principles it is possible to remove the
+monopolisation factor and increase the bandwidth between the client and
+server.

+* P2P Module Implementation
+:PROPERTIES:
+:CUSTOM_ID: p2p-module-implementation
+:END:
+The P2P module is for managing server information within the network. 
+It maintains and updates the IP table, ensuring accuracy by preventing duplicates and removing 
+entries for unreachable servers. Furthermore, the module conducts speed tests on the listed servers 
+to determine upload and download speeds. This valuable information enables users to identify nearby 
+servers with optimal performance, enhancing their overall network experience.
+
+#+caption: UML diagram of P2P module
+[[file:Docs/images/p2pmoduleArch.png]
+
+The peer to peer implementation was built from scratch. This is because
+other peer to peer libraries were on the implementation of the
+Distributed hash table. At the current moment all those heavy features
+are not needed because the objective is to search and list all possible
+servers available. The limitation being that to be a part of the network
+the user has to know at least 1 server. The advantage of building from
+scratch makes the module super light and possibility for custom
+functions and structs. The sub topics below will mention the
+implementations of each functionality in depth.
+
+** IP Table
+:PROPERTIES:
+:CUSTOM_ID: ip-table
+:END:
+The ip table file is a json as the format with a list of servers ip
+addresses, latencies, downloads and uploads speeds. The functions
+implemented include read file, write file and remove duplicate IP
+addresses. The remove duplicate IP address function exists because
+sometimes servers IP tables can have the same ip addresses as what the
+client has. The path of the IP table json file is received from the
+configuration module.
+
+#+begin_src json
+{
+  "ip_address": [
+    {
+			"Name": "<hostname of the machine>",
+			"MachineUsername": "<machine username>",
+			"IPV4": "<ipv4 address>",
+			"IPV6": "<ipv6 address (Not used)>",
+			"Latency": <latency to the server>,

+		}

+}
+#+end_src
+
+*** Latency
+:PROPERTIES:
+:CUSTOM_ID: latency
+:END:
+The latency is measured in milliseconds. The route /server_info is
+called from the server and time it takes to provide a json response is
+recorded.

+:END:
+P2PRC currently supports TURN for NAT traversal.
+
+** TURN
+:PROPERTIES:
+:CUSTOM_ID: turn
+:END:
+The current TURN implementation used is FRP. The TURN server is also
+required when a P2PRC node is acting as a Server. The TURN server is
+determined based on the Node with the least amount of latency based on
+the Nodes available on the IPTable. Once a TURN server is determined
+there are 2 actions performed. The first one is =/FRPPort= to the TURN
+server to receive a port which is used to generate the external port
+from the TURN server. The flow below describes the workflow.

+the future implementation the config file will have information such as
+number of hops and other parameters to tweak and to improve the
+effectiveness of the peer to peer network. The configuration module was
+implemented using the library Viper. The Viper library automates
+features such as searching in default paths to find out if the
+configuration file is present. If the configuration file is not present
+in the default paths then it auto generates the configuration file. The
+configurations file can be in any format. In this project the

+quickly do a map port and domain name mapping in a single command.
+
+*** 1. Find a program you want to run
+       Let's try to setup a really easy program (Let's do with Linkwarden
+       with docker compose :) ). This is under the assumption you have docker
+       compose installed on your local machine.
+       
+**** Let's run Linkwarden using docker compose and P2PRC
+       [[https://docs.linkwarden.app/self-hosting/installation][Installation instructions]]:

+
+       If setup correctly linkwarden should
+       be running.

+
+* Ideas for future potencial features
+Consists of personal loideas for the future of P2PRC.
+At moment only has main contributors writiing to this.
+
+** To support hetrogenous set of Nodes that cannot run P2PRC
+This stems from a personal issue I have when doing research
+on [[https://github.com/CTSRD-CHERI/cheribsd][CheriBSD]] kernel. For my research I am using the ARM morello
+which is a 128bit ARMv8 processor. At the moment Go programs
+can cannot compile and run inside the CPU. This means I cannot
+run P2PRC at the moment inside the ARM morello to remotely access
+it when it's behind NAT using P2PRC. This would indeed be a common
+problem when running against various Architectures that do not
+support running P2PRC. As you will see soon this also creates
+oppurtunity space to scale faster to nodes in a local network
+and would introduce a new layer fault tolerance within a local
+network nodes.
+
+*** Assumptions:
+       - I have a Morello board that cannot run P2PRC
+       - The Morello has a local IP address (ex: 192.168.0.10)
+       - I have 2 laptops running P2PRC in that local network.
+       - This means I have 2 ways to access the Morello board: Which is to SSH
+	 into either 2 laptops and then SSH into 192.168.0.10 to gain access
+	 to the board. Wouldn't it be great to automate this whole layer and
+	 as well look into custom tasks into the hetrogenous hardware.
+*** Set of interesting possible:
+     We build a cool set possibilities before and use this to build up the implementation
+     plan.
+       - We can use P2PRC access the morello board remotely in a single command.
+       - We can use the P2PRC protocol to run servers inside the morello board via traversed
+	 node locally which can access that Node.
+       - Spin servers on node not running P2PRC using the P2PRC standard abstractions.
+       - Auto-setup P2PRC nodes with just SSH access via potencially a DSL.
+       - A neat use case for CHERI for instance would be use the architecture to run light
+	 weight hypervisors. 
+*** Implementation
+     - To use implementations similar to [[https://linux.die.net/man/1/socat][socat]] to ensure we can bind address of local
+       nodes to a node running P2PRC and the node running P2PRC can do a local map port.
+     - We are working on hardening the implementation of the --mp (Map port) to even
+       map ports to machines which remotely running P2PRC. This means of instance I
+       can issue a command to the Morello board without the morello board being in
+       my local network.
+     - We would want to implement the exsisting P2PRC public key mechanism as well so that
+       other nodes can access the Morello board who have permission access.
