What is Bitcoin-PoCX?Bitcoin-PoCX is a fork of Bitcoin Core that replaces Proof-of-Work with
Proof of Capacity (PoCX).
Instead of burning electricity with continuous hashing, miners use
disk space:
- You generate plots once and store them on your drive
- Mining becomes a simple disk read
- Power usage drops to near-idle levels
Your mining power = your storage capacity.
A terabyte is a terabyte — whether it's in your phone, your laptop, your NAS, or a data center.
No ASICs. No GPU arms race. No 20 kW rigs. Just free space on a hard drive.
Why mine BTCX?- No specialized hardware required
- Extremely low power consumption
- Start with spare disk space
- No ASIC or GPU advantage
- Fair launch — everyone starts at block 0
Mining is accessible again.

Fair LaunchMainnet launches at block 0 on
2026-05-03 12:49:37 UTC (Unix timestamp
1,777,777,777). Every participant sees the same rules from the first block.
It is a fair launch:
- No premine. Not a single BTCX exists before block 0.
- No ICO, no presale, no private round. Nobody bought in early.
- No founder allocation and no dev tax. Developers mine the same way you do; zero percent of the block reward is diverted.
PoCX Key Innovations — Compared to Previous PoC ProjectsPoCX builds on the Proof-of-Capacity lineage started by Burstcoin and carried forward by Signum, addressing the issues that held previous generations back.
1. Hardened Plot Format (X1)Earlier PoC systems allowed attackers to store less data than honest miners. PoCX fixes this. Reconstructing missing data is computationally more expensive than storing it — making shortcuts ineffective.
-> Mining power is strictly proportional to stored capacity.2. Stable Block Times (Time Bending)Classic PoC systems produce highly irregular block times. PoCX reshapes the distribution to reduce extreme delays while keeping the 120-second average.
-> More predictable block production.3. Built-in Pool Support (Non-Custodial)Pooling is integrated into consensus from day one. Miners can delegate forging rights without giving up control over funds or plots.
-> Pools never take custody. Delegation is fully reversible.4. Dynamic Scaling (Xn)As hardware improves, the required plot work increases over time (X1 -> X2 -> X3 ...). Each level embeds more work into the plots.
-> Security increases over time, without hard forks.
Roadmap & Status- [✓] Phase I — Consensus design, cryptographic core, RPC surface
- [✓] Phase II — Bitcoin Core integration, Qt/Phoenix wallet, full documentation
- [✓] Phase III — Public testnet live since December 2025, currently at ~78,000 blocks; testnet explorer and testnet mining pool operational
- [▶] Phase IV — Mainnet Genesis: Unix timestamp 1,777,777,777 -> 2026-05-03, 12:49:37 UTC
- [ ] Phase V — Stabilisation
SoftwareThe following releases currently power the
public testnet. Mainnet versions will be released around genesis.
Phoenix WalletAll-in-one wallet, plotter, and miner (Windows, macOS, Linux, Android).
-> Recommended for most users.Bitcoin Core PoCXFull node based on upstream Bitcoin Core.
-> Headless + RPC + Qt GUI.PoCX FrameworkHigh-performance Rust plotter and miner for advanced setups.
-> SIMD + OpenCL support.All binaries and source code:

About the DevelopersBitcoin-PoCX is developed by the
Proof of Capacity Consortium (PoCC).
- Almost 10 years of Proof-of-Capacity development
- Former maintainers of Burstcoin core software (BRS)
- Creators of the most widely used PoC plotter and miner (still the basis of Signum's mining stack)
Bitcoin-PoCX is a full-stack return — built directly on Bitcoin Core, with a next-generation PoC design.
Get Involved Before Mainnet- Read the whitepaper — available in 33 languages.
- Download Phoenix Wallet from the GitHub releases page and run it against the testnet.
- Plot a few GiB on a spare drive and point the miner at it.
- Join the testnet pool at pool.testnet.bitcoin-pocx.org to test non-custodial pool mining end-to-end.
- Hang out on Discord or Telegram — ask questions, report bugs, run a seed node.
Every test block helps harden mainnet.
FAQIs this a Bitcoin fork or a new chain?A new chain based on Bitcoin Core, with a different consensus mechanism (PoCX).
Why not use existing PoC coins?PoCX addresses known weaknesses in earlier PoC designs and integrates directly into modern Bitcoin Core.
What hardware is required?Almost anything with storage and a supported CPU can participate. Beyond standard PCs, the miner has been successfully tested on Android phones, handheld gaming devices, TV sticks, set-top boxes, and Raspberry Pi-class hardware. If it can store data and run the software, it can mine.
Is mining really fair?Yes. No premine, no ICO, no hidden allocations. Everyone starts at block 0.
