Bitcoin fork with RandomX CPU Mining | A Second Chance at Early Bitcoin Mining

[Block Zero]

Block Zero (BLOZ) – RandomX CPU Mining
A second chance at Genesis – CPU mining with normal PCs again

Hello miners,

I would like to introduce Block Zero (BLOZ) to the mining community.

Block Zero is a new RandomX Proof-of-Work blockchain focused on CPU mining, fair launch principles and the old feeling of early Bitcoin mining — when ordinary users could still participate with normal hardware.

This thread is mainly about the mining side of the project:
solo mining, pool mining, hashrates, setup help, miner configs, pool listings and community feedback.


Mining Overview

Coin: Block Zero  
Ticker: BLOZ  
Algorithm: RandomX  
Consensus: Proof-of-Work  
Mining type: CPU mining  
Block time: ~10 minutes  
Block reward: 50 BLOZ  
Launch: Fair launch  
Premine: No premine  
Presale: No presale  
ASIC focus: No, CPU-first via RandomX  


Why RandomX?

RandomX was chosen because it gives normal CPU miners a real chance to participate.

The idea behind Block Zero is not to create another coin where mining is immediately dominated by huge industrial setups, ASICs or insiders.

The goal is to bring back some of the early Bitcoin feeling:

Download the software.  
Run a node.  
Start mining.  
Find blocks.  
Be early.

Of course, times have changed since Bitcoin’s first years. But the feeling of joining a fresh Proof-of-Work network from the beginning is still something many miners are looking for.


Mining Options

You can currently mine BLOZ in different ways:

1. Solo mining  
Best for miners who want to support decentralization directly and are comfortable running their own node.

2. Pool mining  
Better for smaller miners who want more regular payouts and lower variance.

3. Community mining setups  
Some community members are already building tools, bots and pool infrastructure around BLOZ.


Recommended Hardware

Because BLOZ uses RandomX, CPU performance matters most.

Good CPUs for mining include:

• AMD Ryzen 9 CPUs
• AMD EPYC CPUs
• Threadripper CPUs
• Modern high-core-count desktop CPUs
• Efficient CPUs with good memory performance

RandomX also benefits from:

• Fast RAM
• Good memory timings
• Enough cache
• Stable cooling
• Efficient power settings

GPU is not the main factor for BLOZ mining.


Pools

Pool operators are welcome.

If you run a BLOZ pool, please share:

• Pool URL
• Fee
• Minimum payout
• Hashrate
• Source code or pool software used, if possible
• Contact information
• Status page / statistics

Transparency is important.

Unofficial pools are welcome, but they should be clearly marked as unofficial. Pool operators should provide correct hashrate statistics, payout information and basic security information.


Dev & Growth Fund

Block Zero has a small Dev & Growth Fund built into the consensus rules.

The fund is used for things like:

• Seed nodes
• Explorer infrastructure
• Pool support
• Wallet builds
• Bridge infrastructure
• Listings
• Maintenance
• Community growth

This is not extra inflation. It is part of the normal block reward distribution.

The reason for this is simple: today, launching and maintaining a blockchain needs infrastructure. Unlike Bitcoin in 2009, new projects now need explorers, pools, wallets, listings, security monitoring and community support from the beginning.

What We Are Looking For

We are especially looking for:

• CPU miners
• Pool operators
• RandomX miners
• People who can test mining setups
• Linux and Windows users
• Community tool builders
• Explorer / wallet / bot developers
• Feedback from experienced Bitcointalk miners

If you mine BLOZ, feel free to post your:

• CPU model
• Hashrate
• Power usage
• Miner software
• Pool or solo setup
• Operating system
• Optimization tips

This thread should become a place for mining information, configs, pool links and technical feedback around Block Zero.


Final Words

Block Zero is still early.

The main idea is simple:

A fair Proof-of-Work launch.  
RandomX CPU mining.  
No presale.  
No premine.  
A second chance at that early mining feeling.

If you missed the early Bitcoin mining era, this is the kind of project that tries to bring back at least part of that experience.

Miners, pool operators and testers are welcome.

Let’s mine the narrative.

So, no halving, difficulty adjustments, or anything else to ensure the average block mining time is 10 minutes? Or is the average less than that?

Replicating the same Bitcoin with the same method might not guarantee the token's success, especially since many will likely sell it as soon as possible, making its value on the DEX extremely important.

Furthermore, easier mining would lead to reaching 21 million quickly.

@hugeblack appreciate you actually reading it and asking real questions -

You're right to ask: yes, halvings and difficulty retarget are in the code.

Quick params:

[]Target block time: 10 min
[]Retarget: every 72 blocks (~12h)
[]Subsidy: 50 BLOZ → halving every 210,000 blocks
[]Max supply: 21,000,000 BLOZ


Same basic emission idea as Bitcoin — just RandomX on CPU instead of SHA256.

More hashrate doesn't mean we hit 21M faster. Difficulty catches up. We're still early since genesis (June 6), so block times can wobble until hashrate settles.

Live chain: https://explorer.bloz.org]explorer.bloz.org
Code on Github: Rexemre/blockzero-core

On price — also fair. People will sell, liquidity is thin.

[]wBLOZ on PancakeSwap (small pool)
[]Native BLOZ NestEx listing in progress [/list] We're not selling this as the next BTC.

Honestly we're just trying to run a fair CPU coin properly — open code, live pool, no premine.

If something in the params looks off to you, say the word and we'll check it against the repo.

Personally, the goal of enjoying the early days of Bitcoin mining sounds like an unappealing goal to me. Assuming this project take off, wouldn't the experience wear off fast so the entry gets higher? Another point would be whether there's enough security on the chain itself to prevent attacks if the cost to mine is still low even after you've run for some time.

Anyway, is CPU mining still popular these days compared to leasing it to the cloud or something similar?

[hugeblack]

You're right to ask: yes, halvings and difficulty retarget are in the code.

In short, you've turned back the clock and changed nothing. Bitcoin succeeded in its early days because there was no competition or malicious attacks, but in the case of Block Zero (BLOZ), someone with sufficient computing power could destroy the network.

How many confirmations are required for a transaction to be considered final? A 10-minute delay for a single confirmation would be unacceptable. A user would need more than 100 confirmations for their transaction to be considered final (100 * 10 = 1000 minutes).

[Block Zero]

@hugeblack @elda34b — thanks both for the honest questions.

On "you changed nothing":

Fair pushback. We didn't claim to reinvent monetary theory — the emission side is intentionally Bitcoin-like (50 BLOZ → halving every 210k → 21M cap, 10 min target, retarget every 72 blocks). That's the fair-launch PoW part.

What did change vs 2009 Bitcoin:

• Mining layer: RandomX on CPU instead of SHA-256 — home hardware can compete again, not ASIC warehouses
  
• Reality of 2026: back then there was no competition, no pools, no explorers, no bridge, no listing pressure. Today you need infrastructure from day one or the chain dies quietly
  
• Dev & Growth Fund (since block 1500): on-chain rule — every coinbase pays a minimum of 10% of the block subsidy to a public fund address
  Code:

  bz1qmv7lyweytwy807f6yq78zfvhh5ye5y2y0x2gfl

  . Consensus minimum 10%. Not extra inflation — it's deducted from the existing 50 BLOZ reward (miners get ~45 BLOZ, fund gets ~5 BLOZ at 10% settings). Used for seed nodes, explorer, pool, wallet builds, bridge, listings, maintenance — the stuff Satoshi didn't need in 2009 but every new PoW coin needs now to survive against hundreds of competitors
  
  
  So: same broad money rules, different mining game + modern infrastructure funding baked into consensus. Code: mre/blockzero-core/blob/main/src/kernel/chainparams.cpp]chainparams.cpp
  
  On security / low hashrate (@hugeblack, @elda34b):
  
  You're not wrong — a young chain at ~2 MH/s is easier to 51% than Bitcoin today. We're not pretending BLOZ is 17 years battle-tested. Security grows with distributed hashrate and nodes; early miners/operators are part of building that. RandomX also changes the attack economics vs SHA-256 (can't just rent an ASIC farm for an hour), but that doesn't make us magically safe — just different.
  
  On confirmations / "100 × 10 min" (@hugeblack):
  
  I think there's a mix-up here. 100 blocks = coinbase maturity — miner's block reward locked ~100 blocks (~16–17 hours at target) before it can be spent. Prevents spending immature coinbase outputs after reorgs.
  
  For normal payments it's the same model as Bitcoin:
  
  • 1 confirmation ≈ one block (~10 min target)
  • 6 confirmations = usual practical bar for larger amounts (convention, not a protocol rule)
  • Exchanges/services set their own deposit rules — nobody waits 100 confs for a coffee
  
  On "early Bitcoin feeling wears off fast" (@elda34b):
  
  Also fair. If hashrate and difficulty climb, entry cost rises — same as every PoW coin that grows. We're not selling nostalgia as a permanent state. The pitch is simpler: right now it's still early, CPU-accessible, fair launch, no premine. Whether that window stays open depends on the community, not a marketing line.
  
  On CPU mining vs cloud (@elda34b):
  
  CPU mining is niche again but alive — RandomX coins (Monero-style hardware) still have a crowd that prefers owning the hash on their own box vs renting opaque cloud hash. Pools exist for variance; solo still works if you want to run a node. Different tradeoffs, both valid.
  
  On price / DEX (@hugeblack):
  
  Agreed — people will sell, liquidity is thin. wBLOZ on PancakeSwap (small pool), native BLOZ NestEx listing in progress. PoW L1 isn't Visa-speed for retail; wBLOZ on BSC is the faster trading layer, native BLOZ is mining/settlement.
  
  We're not selling "the next Bitcoin." Open code, live pool (0% fee), no premine. If anything in the params looks wrong, say the word — happy to walk through the repo line by line.
