How to

1. Download

1. Get the package from the download page: nyr-0.1.0.zip.
2. Unpack. Inside: the nyr binary (Linux x86_64) and the spec.
3. Make it executable:

chmod +x nyr
sudo install -m 755 nyr /usr/local/bin/nyr
nyr --help

After that, just nyr — not /opt/nyr/nyr. Wordlist is in the binary, glibc only.

2. Chain file

A node keeps the chain in one file. Genesis is created on first start. If the file is /var/lib/nyr/nyr.chain, nyr finds it on its own.

sudo mkdir -p /var/lib/nyr
nyr status

Reference node: v41089.1blu.de:19191 · port 19191 (P2P). 19192 is reserved.

3. Start a node

1. Create a receive address in NÝR-Wallet.
2. In a terminal:

nyr node

In a terminal this opens the node TUI (English, same feel as the wallet TUI). If the node is already a service, the TUI only attaches — Q closes the screen, not the node. Reward and peers: R P, seal/drop: S D. Without a terminal: nyr node --plain.

The node counts work seconds (0.00001 NÝR/s, cap 0.86400/day) and seals transfers. Open TCP 19191 if other nodes should reach you.

On testnet a transfer confirms once 2 other nodes have acknowledged it.

NFTs — pictures beside the chain

Each NFT image is a JPEG, at most 512×512, stored next to the chain file: nft/<blake2b>.jpg. The chain keeps only the hash and the owner address. The NÝR-NFT app picks an image, crops/scales it, POSTs it to a node (IP:port, default 195.90.214.85:19191) and mints there. Nodes gossip the files — if one node dies, the pictures stay on the others.

Minting costs 0.25000 NÝR — deliberately expensive. The fee goes to the reward wallet of the node that stores the picture.

HTTP: POST /nft (JPEG) · POST /nft/mint · GET /nft · GET /nft/{hash} · fee 0.25000 NÝR

Keys — node TUI

Key	Action
R	[R] Reward — address that receives the work
P	[P] Peers — 1–5 gossip nodes
S	[S] Seal — seal the mempool now
D	[D] Drop — pay accrued work now (test)
Q	[Q] Quit — stop the node
