SilkNode

A privacy-preserving stablecoin protocol with CPU mining.

• SILK (SLK) — Native mining coin. CPU-mineable via RandomX. 100M supply + perpetual tail emission. Secures the network.
• SND (Silk Node Dollar) — Privacy stablecoin. Minted 1:1 against locked USDC/USDT. Free to send. Fully backed.

Built on a CryptoNote fork with stealth addresses, ring signatures, and RingCT for full transaction privacy.

Two-Token Model

  SILK (SLK)                              SND (Silk Node Dollar)
  ──────────                              ──────────────────────
  Earned by miners (CPU only)             Minted 1:1 when USDC/USDT deposited
  Secures the network via PoW             Free to send — no fees, no gas
  100M supply + 0.3 SLK/min tail         Supply = total locked stablecoins
  RandomX (ASIC-resistant)                Backed by on-chain lockbox contracts
  Smooth 20-year emission curve           Pegged to $1 USD

The Silk Weave: Miners earn bonus SILK when blocks include deposit proofs. More stablecoin usage → higher mining rewards → more hashrate → stronger security. The first PoW system where mining rewards are directly linked to real-world payment volume.

How It Works

Deposit: Lock USDC/USDT in a lockbox contract on any supported chain → Oracle detects deposit → SND minted privately on SilkNode.

Send: SND transactions are fully private (ring signatures + stealth addresses). No fees. No gas. Instant.

Withdraw: Burn SND on SilkNode → Oracle signs a withdrawal proof → Claim USDC/USDT on your chosen chain.

Mine: Run the daemon, point your CPU at it. Earn SILK block rewards + bonus SILK from deposit proofs.

Quick Start

Build the Node

# Install dependencies (Ubuntu/Debian)
sudo apt install build-essential cmake pkg-config libssl-dev libzmq3-dev \
  libunbound-dev libsodium-dev libunwind8-dev liblzma-dev libreadline6-dev \
  libpgm-dev libhidapi-dev libusb-1.0-0-dev libprotobuf-dev \
  protobuf-compiler libudev-dev libboost-all-dev

# Build
make release -j$(nproc)

Binaries output to build/release/bin/:

• monerod — daemon
• monero-wallet-cli — wallet CLI
• monero-wallet-rpc — wallet RPC server

Run a Node

./build/release/bin/monerod --non-interactive --confirm-external-bind

Mine SILK

# Via RPC (recommended)
curl -X POST http://127.0.0.1:28081/json_rpc \
  -d '{"jsonrpc":"2.0","id":"0","method":"start_mining","params":{"miner_address":"YOUR_ADDRESS","threads_count":4}}'

Run the Web UI

cd ui
cp .env.example .env.local  # Configure RPC URLs and contract addresses
npm install
npm run dev

Deploy Lockbox Contracts

# EVM (e.g. Base)
cd lockbox
cp .env.example .env  # Set DEPLOYER_PRIVATE_KEY and RPC URL
npm install
LOCKBOX_VERSION=v3 npx hardhat run scripts/deploy.js --network base

# Solana
cd solana_lockbox
anchor deploy --provider.cluster mainnet-beta

# Tron
cd tron_lockbox
cp .env.example .env
npm install
LOCKBOX_VERSION=v3 npm run deploy:mainnet

Privacy Model

• Ring signatures — Transaction inputs are mixed with decoys. Nobody can tell which input is real.
• Stealth addresses — Every transaction creates a one-time address. Recipient's real address never appears on-chain.
• RingCT — Transaction amounts are hidden using Pedersen commitments.
• Fixed denominations — Deposits use fixed sizes (1, 10, 100, 1000 USDC) to prevent amount-based deanonymization.
• Commitment scheme — Deposit details are committed as hashes on-chain, revealed only to the oracle off-chain.

Network

• P2P port: 28080
• RPC port: 28081
• Mainnet addresses start with B
• Seed node: 46.101.89.213:28080
• Website: silknode.io
