Baseline Cash (BLINE) - SHA256d PoW - ASIC Resistant

Baseline Cash is a fast, minimalist SHA256d payments network for everyday transfers, with an optional on-chain "send later" feature for a more bank-like experience.

Highlights

SHA256d PoW (ASIC-friendly)
Fast cadence: 20 second blocks
Difficulty: per-block LWMA retarget designed to react quickly to hashrate swings
No premine / no airdrop: genesis coinbase pays 0
Optional scheduled sends: reserve a payment for a future time, enforced by consensus rules
Operator-friendly stack:
- Built-in wallet + GUI wallet
- Built-in explorer-ready address index
- Built-in Stratum v1 server + payout tracker (run a pool without extra daemons)

Network Parameters (Mainnet)

Ticker: BLINE
PoW: SHA256d
Target block time: 20s
Difficulty retarget: LWMA, per-block, window 60, solvetime clamp 1..6xT
Coinbase maturity: 20 blocks
PoW limit (easiest): 0x1e08637b (also used for genesis bits)
Start difficulty (height 1): 0x1d0225c1
Foundation fee: 1% of subsidy (not fees), paid in coinbase (Used for development, liquidity and network ops)
Ports:
- P2P: 9333
- RPC: 8832
- Stratum: 3333
Network ID (handshake): baseline-mainnet-2025-12-28

Emission / Supply

Base reward starts at 50 BLINE and decays smoothly each block (exponential curve).
Half-life: 4,158,884 blocks (~2.64 years)
Theoretical cap: ~300,000,000 BLINE (asymptotic)

Quick Start (Run a node)

Windows
Install Python 3.12+ and Git for Windows, then run:

Code:

git clone https://github.com/Baseline-Blockchain/baseline-node.git
cd baseline-node
py -3 -m venv .venv
.venv\Scripts\activate
pip install -e .
baseline-node --config config.json --log-level info

macOS / Linux
Install Python 3.12+ and Git, then run:

Code:

git clone https://github.com/Baseline-Blockchain/baseline-node.git
cd baseline-node
python3 -m venv .venv
source .venv/bin/activate
pip install -e .
baseline-node --config config.json --log-level info

Important: change RPC credentials in config.json before exposing anything to the internet.

Mining (Stratum)
Baseline Cash nodes can run Stratum v1. To mine, you need a node/pool with Stratum enabled.

1) Configure a pool payout key (required)

Generate a key:

Code:

baseline-wallet generate-key

Put the hex key into config.json:

Code:

mining.pool_private_key: "<HEX_KEY_HERE>"

2) Start the node (Stratum will listen on :3333 by default)

3) Point a miner

Any SHA256d ASIC that supports Stratum v1 (most Bitcoin ASICs) can connect.

Which URL to use:

If your miner runs on the same machine as the node/pool: use 127.0.0.1
If your miner is on the same LAN: use your node's LAN IP (example: 192.168.1.50)
If you connect to a public pool: use the pool domain/IP

Example (command-line miner,):

Code:

git clone https://github.com/Baseline-Blockchain/baseline-miner.git
cd baseline-miner
py -3 -m venv .venv # or python3 -m venv .venv on linux
.venv\Scripts\activate # or source .venv/bin/activate on linux
pip install -e .

baseline-miner --gpu --host pool.baseline.cash --port 3333 --address YOURADDRESS --worker worker1

Explorer / Wallet

Explorer: https://explorer.baseline.cash
Wallet GUI: bundled in the repo. After pip install -e ., run baseline-wallet-gui from that same venv (or use .venv/Scripts/baseline-wallet-gui on Windows). It connects to a running node via JSON-RPC (local or remote; edit config.json).

Fair Launch Notes

No premine, no airdrop.
Mainnet genesis is hardcoded and verifiable via the repo.

Liquidity / Listings

No paid exchange listing at launch. I'm not raising funds or doing airdrops.
Initial distribution is 100% PoW mining (no premine).
Plan: focus on stable mainnet ops (seeds, explorer, pools) first; if there is organic usage and hashrate, I'll pursue low-cost listings and/or OTC/community liquidity.

FAQ
Why Python? The goal is a simple, auditable full stack (node + wallet + explorer/pool tooling) with minimal dependencies; the node uses async I/O and includes practical DoS mitigations like message-size checks, per-IP/total connection limits, and token-bucket rate limiting (P2P/RPC) plus per-peer mempool submission budgets.

Disclaimer
This is experimental software. Use at your own risk. Verify builds, verify genesis, and don't run wallet RPC endpoints publicly without authentication.
