📊 OVERVIEW S256 is a Bitcoin fork that takes the contrarian approach to cryptocurrency. While others chase faster blocks and easier mining,
S256 embraces difficulty.
Built on Bitcoin Core v30.0, S256 doubles key parameters for increased scarcity and deliberation:
- Longer block times encourage thoughtful transactions over rushed decisions
- Higher difficulty demands real proof of work
- Extended halving cycles create sustainable, long-term value
Genesis Block: November 30, 2025
Current Block: ~12,000
Status: ✅ Live and Mining
⚙️ SPECIFICATIONS Block Time: 20 minutes (2x Bitcoin's 10 minutes)

🏛️ PHILOSOPHY: "DIGITAL PLATINUM" "Because excellence takes effort."
S256 embraces difficulty rather than avoiding it:
🔨 Harder to Mine, Not Easier Longer block times mean each block requires sustained effort and commitment.
⏰ Longer Blocks for Deliberation 20-minute blocks encourage thoughtful transactions over rushed decisions.
💎 True Scarcity Through Difficulty Real value comes from real work, not artificial speed.
⚖️ Proof of REAL Work S256 doesn't compromise on the fundamental principle of proof-of-work.
⛏️ MINING Algorithm: SHA256 (Bitcoin compatible)
Compatible Hardware: Any Bitcoin ASIC miner (Antminer S19, S21, Whatsminer M50, etc.)

❓ FAQ Q: Is S256 a Bitcoin fork? A: Yes, S256 is based on Bitcoin Core v30.0 with modified consensus parameters (2x theme).
Q: Can I mine with my Bitcoin ASIC? A: Absolutely! S256 uses SHA256, so any Bitcoin mining hardware works.
Q: What makes S256 different? A: We embrace difficulty with 20-minute blocks, 8-year halvings, and a focus on real proof-of-work.
Q: Was there a premine or ICO? A: No. S256 is 100% proof-of-work with fair distribution from genesis.
Q: Why 84 million supply instead of 21 million? A: Everything is 2x - blocks, rewards, supply, halvings. It's the core philosophy of "Double the
Work, Double the Value."
Q: When exchange listings? A: We're focusing on building a solid community first. Exchange listings will come naturally as the project grows.
Q: How can I contribute? A: Join our Discord/Telegram, run a node, mine S256, help with documentation, or submit code on GitHub!
Q: What wallets are supported? A: Currently the official S256 Core wallet (QT and daemon). More wallets coming as community grows.
