nkn's Introduction

NKN Full Node

Official Go implementation of NKN full node.

Dev Status: V2 line, Production (Stable and Feature-Complete)

NKN, short for New Kind of Network, is a project aiming to rebuild the Internet that will be truly open, decentralized, dynamic, safe, shared and owned by the community.

Official website: https://nkn.org/

Note: This is the official full node implementation of the NKN protocol, which relays data for clients and earn mining rewards. For client implementation which can send and receive data, please refer to:

Introduction

The core of the NKN network consists of many connected nodes distributed globally. Every node is only connected to and aware of a few other nodes called neighbors. Packets can be transmitted from any node to any other node in an efficient and verifiable route. Data can be sent to any clients without public or static IP address using their permanent NKN address with end-to-end encryption. The network stack of NKN network is open source at another repo called nnet that can be used to build other decentralized/distributed systems.

The relay workload can be verified using our Proof of Relay (PoR) algorithm. A small and fixed portion of the packets will be randomly selected as proof. The random selection can be verified and cannot be predicted or controlled. Proof will be sent to other nodes for payment and rewards.

A node in our network is both relayer and consensus participant. Consensus among massive nodes can be reached efficiently by only communicating with neighbors using our consensus algorithm based on Cellular Automata. Consensus is reached for every block to prevent fork.

More details can be found in our wiki.

Technical Highlights

Transmit any data to any node/client without any centralized server.
Proof-of-Relay, a useful proof of work: mining is relaying data.
Extremely scalable consensus algorithm (billions of nodes within seconds).
Strong consistency rather than eventual consistency.
Dynamic, large-scale network.
Verifiable topology and routes.
Secure address scheme with public key embedded.

Use pre-built binaries

You just need to download and decompress the correct version matching your OS and architecture from github releases.

Now you can jump to configuration for how to configure and run a node.

Use pre-built Docker image

Prerequirement: Have working docker software installed. For help with that visit official docker docs

We host latest Docker image (the same as you build with docker) on our official Docker Hub account. You can get it by

$ docker pull nknorg/nkn

Now you can jump to configuration for how to configure and run a node.

Building using Docker

Prerequirement: Have working docker software installed. For help with that visit official docker docs

Build and tag Docker image

$ docker build -f docker/Dockerfile -t nknorg/nkn .

This command should be run once every time you update the code base.

Building from source

To build from source, you need a properly configured Go environment (lookup the required version within go.mod, and see Go Official Installation Documentation for install instructions).

Build the source code with make

$ git clone https://github.com/nknorg/nkn.git
$ cd nkn
$ make

Run Unit Tests

# run all tests
$ go test -v ./...

# run only specific tests
go test -v ./chain/store

After building is successful, you should see two executables:

nknd: the nkn node program
nknc: command line tool for nkn node control

Now you can see configuration for how to configure and run a node.

You can also build binaries for other architectures by executing make all. The resulting binaries are stored in build directory.

Configuration

When starting a NKN node (i.e. running nknd), it will reads a few configurable files: config.json for configuration, wallet.json for wallet, and certs/* for certificates. Additionally, it will read directory web for web GUI interface static assets. By default nknd assumes they are located in the current working directory.

For Docker, a directory containing config.json, wallet.json (if exists) and certs/ should be mapped to /nkn/data directory in the container. If not provided, the default config and certs will be copied to /nkn/data/, and a wallet and random password will be generated and saved to /nkn/data/ on nknd launch.

The path of config file, wallet file, database directory and log directory can be specified by passing arguments to nknd or in config.json, run nknd --help for more information.

`config.json`:

We provide a few sample config.json:

config.mainnet.json: join the mainnet
config.local.json: create and join a private chain on your localhost

You can copy the one you want to config.json or write your own.

For convenience, we ship a copy of config.mainnet.json in release version (as default.json) and in docker image (under /nkn/). The docker container will copy this default one to /nkn/data/config.json if not exists on nknd launch.

If config file is not provided, node will join the mainnet by default.

`wallet.json`:

Before starting the node, you need to create a new wallet first. Wallet information will be saved at wallet.json and it's encrypted with the password you provided when creating the wallet. So please make sure you pick a strong password and remember it!

$ ./nknc wallet -c
Password:
Re-enter Password:
Address                                Public Key
-------                                ----------
NKNRQxosmUixL8bvLAS5G79m1XNx3YqPsFPW   35db285ea2f91499164cd3e19203ab5e525df6216d1eba3ac6bcef00503407ce

[IMPORTANT] Each node needs to use a unique wallet. If you use share wallet among multiple nodes, only one of them will be able to join the network!

If you are using Docker, it should be docker run -it -v ${PWD}:/nkn/data nknorg/nkn nknc wallet -c instead, assuming you want to store the wallet.json in your current working directory. If you want it to be saved to another directory, you need to change ${PWD} to that directory.

The docker container will create a wallet saved to /nkn/data/wallet.json and a random password saved to /nkn/data/wallet.pswd if not exists on nknd launch.

`certs/`

nknd uses Let's Encrypt to apply and renew TLS certificate and put in into cert/ directory. By default nknd will generate certificate with x-x-x-x.ipv4.staticdns{1,2,3}.io domain name which x-x-x-x is your ipv4 address, replace dot with dash. The default cert domain is deprecated and will be removed in the future version. Please provide your own domain or cert if you need to use tls.

If you would like to use your own domain name, simply set CertDomainName with your domain name in config.json, nknd will automatically apply or renew certificate from Let's Encrypt and deploy it.

If you already have certificate and want to use it in nknd, you can put it in the certs directory then set HttpsJsonDomain HttpWssDomain with your domain name, HttpsJsonCert HttpsJsonKey HttpWssCert HttpWssKey with your certificate full chain file and private key file.

Data and Logs

After nknd starts, it will creates two directories: ChainDB to store blockchain data, and Log to store logs. By default nknd will creates these directories in the current working directory, but it can be changed by passing --chaindb and --log arguments to nknd or specify in config.json.

Now you can join the mainnet or create a private chain.

Join the MainNet

[IMPORTANT] In order to join the MainNet, you need to have a public IP address, or set up port forwarding on your router properly so that other people can establish connection to you.

If you have done the previous steps correctly (config.json, create wallet, public IP or port forwarding), joining the MainNet is as simple as running:

$ ./nknd

If you are using Docker then you should run the following command instead:

$ docker run -p 30001-30005:30001-30005 -v ${PWD}:/nkn/data --name nkn --rm -it nknorg/nkn

If you would like to enable web GUI interface from outside of the container, you need to replace -p 30001-30005:30001-30005 with -p 30000-30005:30000-30005.

If you get an error saying docker: Error response from daemon: Conflict. The container name "/nkn" is already in use by container ..., you should run docker rm nkn first to remove the old container.

If everything goes well, you should be part of the MainNet after a few minutes! You can query your wallet balance (which includes the NKN token you've mined) by:

$ ./nknc wallet -l balance

or if you are using Docker:

$ docker exec -it nkn nknc wallet -l balance

If there is a problem, you may want to check if any of the previous steps went wrong. If the problem still persists, create an issue or ask us in our Discord group.

[Recommended] Using Beneficiary Address

By default, token mined by your node will be sent to the wallet your node is using, which is NOT as safe as you might think. The recommended way is to use another cold wallet (that is saved and backed up well) to store your token. You can use your code wallet address as beneficiaryAddr in config.json such that token mined by your node will be sent directly to that beneficiary address. This is safer and more convenient because: 1. even if your node is hacked, or your node wallet is leaked, you will not lose any token; 2. if you run multiple nodes, it's the only way that all their mining rewards will go to the same address.

NAT traversal and port forwarding

By default, nknd will try to detect if your node is behind a router and if your router supports UPnP or NAT-PMP protocol, and if success, it will try to set up port forwarding automatically. You can add --no-nat flag when starting nknd OR add "NAT": false in config.json to disable automatic port forwarding. If your router does not support such protocol, you have to setup port forwarding on your router for port 30001 as well as all other ports specified in config.json (30001-30005 by default), otherwise other nodes cannot establish connections to you and you will NOT be able to earn mining rewards even though your node can still run and sync blocks.

When setting up port forwarding, public port needs to be the same as private port mapped to your node. For example, you should map port 30001 on your router's public IP address to port 30001 on your node's internal IP address.

The specific steps to setup port forwarding depends on your router. But in general, you need to log in to the admin interface of your router (typically in a web browser), then navigate to the port forwarding section, and create several mappings, one for each port. One of the easiest way to find out how to setup port forwarding on your router is to search "how to setup port forwarding" + your router model or name online.

Use protobuffer instead of JSON for websocket msg for binary data

Description of the issue

Currently all websocket messages are encoded in JSON, which does not support transmitting binary data natively. Encode binary data with base64 introduces both CPU and bandwidth overhead. This can be avoided by sending binary data directly through websocket. The easy and backward/forward/cross-platform compatible way of doing it is to use protobuffer to encode/decode message.

Documentation improvement

Checklist

Running latest version of the code.
This issue has not been reported earlier.

Your environment

OS: Not relevant
Go version: Not relevant
Release tag/commit of the code: ed50f28

Expected behavior

Registering a name to the public key and then resolving this name should return the corresponding wallet address.

Actual behavior

Registering a name to the public key and then resolving this name returns a different wallet address. One possible cause is a bug in encoding the public key to a wallet address, may be related to migration to Ed25519

Steps to reproduce

(1) Send a transaction to register the name to a public key
(2) Request an NKN address associated with that name

These are actual transactions from my wallet:
(1)
Address: NKNRmDTBZJuByb5HcEE6ZQ8KhCYGpt1uCPnj which has pubkey b77b2a3fe032357644a14d6e8f5c67a87ee8b477131ca1e47e0852638ae0e776
Name to register: somename

this is the request: {"method":"sendrawtransaction","jsonrpc":"2.0","params":{"tx":"0a340a300803122c0a20b77b2a3fe032357644a14d6e8f5c67a87ee8b477131ca1e47e0852638ae0e7761208736f6d656e616d65101412680a232104b77b2a3fe032357644a14d6e8f5c67a87ee8b477131ca1e47e0852638ae0e776ac1241408ce43787a38fefc983493de84b6cf6183e900d68c3a2df1a646efab596c956addc329e94ad89118021399f0991fdf8e898b869bf5403393b6122e04d939a720f"}}

tx successful, with this id: 39d13910c5320ad61fac0f28cb20d97ed484d9833f8700cb6f787918f1fc4e64

(2) After long enough wait time, I sent a request to resolve somename

{"method":"getaddressbyname","jsonrpc":"2.0","params":{"name":"somename"}}

and I received this resoponse: {"result":"NKNGob91RtdLmxUs72UxUKPB8DhAS6qpffpB","id":"1","jsonrpc":"2.0"}

As you can see, the address returned NKNGob91RtdLmxUs72UxUKPB8DhAS6qpffpB is not the same as address registered NKNRmDTBZJuByb5HcEE6ZQ8KhCYGpt1uCPnj

block proposer verification

The validity of block proposer should be verified. The sigchain proof of block proposer should be included in last block.

Use UDP instead of TCP for consensus?

Block and consensus related data transmission could use significant bandwidth. Switching from TCP to UDP could enhance performance, and will not affect correctness due to the fault tolerance of consensus algorithm. Any thoughts are appreciated.

API features request

Description of the issue

getnodestate — would be nice to add the property of latestblockheight and getversion, in order not to send 3 different requests and do not overload the frontend.

NAT Traversal

Description of the issue

Currently we require node to have public IP address. It MAY be beneficial to add NAT traversal for nodes so that people behind NAT can start mining. However, this may cause a few troubles:

A node cannot know its public ports before all connections have already been established
Because of 1, a node cannot know its chord ID in advance
Reconnecting to the network may change chord ID as port is changed
May reduce the performance of the network if some NAT traversal are problematic

Node in syncing shouldn't send updateSigChainBlockHash to client

Currently node send a updateSigChainBlockHash msg to client when his latest block hash changes. Node shouldn't do this when it's syncing, otherwise it's spamming msgs to client.

Occasionally, block is synced from neighbor rather than voted.

Need to think about block syncing time and block generation time.

Use VRF instead of signature for signature chain

Signature chain requires the signature to be random, unique, verifiable. No other signature should be valid. VRF should be used instead of (even deterministic) signature.

Sync the blocks with neighbor when the latest block doesn't match with others

Currently the node period check the neighbor's block status, it is a bit too heavy to run a separated thread to do that, we'd suggest to trigger the sync when the block be found at ising consensus stage. It means the commit "Check local block with neighbor in consensus" need be reimplemented.

Update RPC documentation

Description of the issue

RPC documentation here is kinda old and needs updating according to https://github.com/nknorg/nkn/blob/master/api/common/interfaces.go

Share memory by communicating

Lock is being heavy used, use channel instead.

Should rejoin when node can't catch up with neighbors

when node reconnect with neighbors, such as keepalive timeouts, the node should re-join network rather than exits.

Joining a live node which is not started with "./nkn -test create" can't start block syncing and consensus.

The first node started with "./nknd -test create" should not be configured as GenesisBlockProposer

The first node is a bootstrap node. After networking started, the bootstrap node should be stopped. If use the first node as GenesisBlockProposer, when no signature chain sent in system, the default block proposer will missing. Then block producing will be blocked. So do not use the first node as GenesisBlockProposer in test version.

Use gogoprotobuf for faster marshal/unmarshal

I have been told that gogoprotobuf provides much better performance without sacrifice compatibility. We can consider switch to it.

Sync between node neighbors and chord finger table

Currently node neighbors are read from chord finger table. It would be good to add 2-way binding to make sure they are always sync. E.g. when a node neighbor connection is lost, also remove it from finger table.

Move to Go Modules

Glide wasn't maintained since Sep 26, 2018 and Go 1.13 scheduled for August 2019 will deprecate GOPATH and use Go Modules by default. Moving forward we should stop using glide and start using modules.

Adding Node public key in getnodestate-RPC

Description of the issue

Hence we can parse the public key of the used nodes from the transaction payload it would be nice to get the node’s public key from the getnodestate RPC call.

In combination with the nknx nodecrawler we could then backtrace the way packets are relayed based on the geographic position and also create more „node utilization“ statistics.

Use ed25519 instead of p256

There are several reasons to switch:

Better performance
Better compatibility with VRF
Prepare to switch to deterministic signature (e.g. XEdDSA) as the RNG could be (and has been) the weak point in security

Chrod vs Kademlia

I have noticed that NKN uses Chord DHT.

What is the reason using Chord over Kademlia, when Kademlia has much simpler (and less error prone) implementation?

Use deterministic signature

RNG is probably one of the weakest point in EC based signature. Signing different msg with the same random number will immediately leak the private key. Switching to deterministic EC based signature where the random number is changed to the hash of the msg and private key (e.g. XEdDSA) could solve the problem by making sure different msg are signed with different "random" number.

NKN node on a Raspberry Pi

Description of the issue

NKN team can you please make a YouTube video on how to set up a NKN node on a Raspberry Pi? It would be a good way to grow the NKN network since it has a lower barrier of entry cost wise.
