Bitcoin Lightning Network | T-Shirt

The Bitcoin Lightning Network design explores how Bitcoin payments can scale beyond the base layer. The Lightning Network uses Payment Channels to update balances without recording every payment on-chain. Routed Payments can cross connected channels and often complete quickly with small, variable fees. Successful routing depends on available Liquidity, while channel opening, closing, and dispute resolution rely on Bitcoin’s Base Layer. This Layer 2 Scaling model expands payment capacity while working within Bitcoin’s consensus rules.

Frequently Asked Questions

What is the Bitcoin Lightning Network?
The Lightning Network is a payment protocol built on Bitcoin that uses bidirectional payment channels. Participants can exchange updated channel states without placing every payment on the blockchain. Channel funding, closure, and dispute enforcement ultimately use Bitcoin transactions and scripts.

How do routed Lightning payments work?
A sender does not need a direct channel with the recipient. A conditional payment can be routed across a path of connected channels. The balance updates complete together or the payment fails, and the selected path must have sufficient directional liquidity for the payment amount.

Are Lightning payments always instant and low-fee?
No. Lightning is designed for fast payments with fees that are often small, but speed, cost, and success can vary with route availability, channel liquidity, payment size, and wallet or node behavior. Opening and closing channels also require on-chain transactions, fees, and confirmations.

How do I choose the right size?
Lay a similar T-Shirt that fits you well on a flat surface. Measure its width from armpit to armpit, length from shoulder to hem, and sleeve length from the center back. Compare those measurements with the product-specific size chart and allow for the listed ±1.5 in manufacturing tolerance.

How long does production and shipping take?
This T-Shirt is made to order. Production is estimated at 2–5 business days, followed by 4–8 business days for shipping within the 48 contiguous U.S. states and Washington, D.C. The estimated total delivery time is 6–13 business days.
