Ok... Now what?
Going off testnet?
20% and 3% Dev fee, forever?

PICOIN — The First Proof-of-Pi Blockchain

Public Testnet Status Update

Hello Bitcointalk community,

We are excited to share the current progress of PICOIN, a unique blockchain protocol focused on decentralized computation of the digits of π (Pi) using the BBP algorithm.

PICOIN is introducing a completely new blockchain concept:

• Proof-of-Pi Mining
• Distributed scientific computation
• BBP hexadecimal digit extraction
• Range & sample validation
• Adaptive dynamic difficulty based on real compute cost

Current Public Testnet Progress:

• Wallets fully working
• Real signed transactions
• Transaction propagation between peers
• Replay / Restore / Catch-Up system
• Distributed validators
• Validator wallet integration
• Explorer transaction page fixed
• Real miner rewards & validator rewards
• Dynamic BBP difficulty system implemented
• Improved validator coordination and task handling
• Scientific range + samples verification working

Current Genesis Reward Allocation:

Category	Allocation	Reward per Block
Proof of Pi Miner	80%	2.513280 PI
Science Compute Reserve	7%	0.219912 PI
Validator Reward Pool	10%	0.314160 PI
Scientific Development Treasury	3%	0.094248 PI
Total	100%	3.141600 PI

Validator staking is currently under testing.

The protocol now includes a new dynamic difficulty model specifically designed for BBP scientific computation. Difficulty adjusts according to:

• real mining cost
• range depth inside π
• segment complexity
• validator timing
• network performance

Mainnet launch is currently targeted for early June 2026.

We invite miners, validators and developers to join the public testnet.

I understand your concern. That is exactly why we reduced the Science Compute Reserve from 20% down to only 7%.

Now miners receive 80% of every block reward.

It is also important to understand that the 7% reserve is protected by protocol consensus. In the future, if the community decides to change those percentages, governance can do so.

For Mainnet, that reserve is effectively intended for the future L2 scientific computation layer, where laboratories, research groups and scientific companies could access decentralized computation financed directly by the protocol itself. The goal is to connect blockchain incentives with real scientific computation and expand crypto beyond speculation.

About the Dev Treasury: it is only 3%.

There is another important aspect of PICOIN that many people are missing:

PICOIN mining is not linear like Bitcoin hashing.

As we move deeper into the digits of π, BBP computation becomes increasingly expensive. Difficulty grows dynamically and logarithmically according to the real computational cost of extracting deeper ranges of Pi digits.

That means:
- block production becomes harder over time,
- mining speed naturally slows down,
- issuance becomes logarithmically deflationary.

Today there is no hard fixed supply because the protocol itself progressively increases the computational complexity required to continue mining efficiently.

In the early years this effect may not be obvious, but over time it becomes very significant.

So honestly, is 3% really that high for an entirely new scientific blockchain architecture?

Satoshi mined around 1 million BTC in the beginning, and Bitcoin became one of the most desired assets in the world.

Also, the Dev Treasury in PICOIN is time-locked:
- it can only be unlocked every 3 months,
- it is not an instant dump allocation.

And remember:
this is not another copy-paste fork.

Where are the mining pools for scientific computation?
Where are the blockchain protocols dedicated to calculating the digits of π?
Where are the decentralized scientific compute economies?

PICOIN is trying to build something genuinely new.

This is the real PICOIN.

A blockchain where mining contributes to mathematical computation and scientific progress.

And honestly… if this vision succeeds, early miners may be the luckiest people in crypto.

Hi. I checked out your profile on the forum and I see this is already your third project. The previous two just ended up as promises of a bright future and wealth Why do you think this project can achieve any heights or popularity in the current reality? No offense, just pure curiosity.

[johannFac]

Fair question, and honestly I understand the skepticism.
Most crypto projects never reach maturity, and many founders jump from idea to idea without building anything real.

To be completely transparent, my previous projects were mostly forks and experimental learning stages. At that time, I did not yet have the experience or maturity to fully understand that long-term success in crypto requires something much more difficult: genuinely innovative and unique ideas, not just copies with different branding.

Picoin represents a different stage for me technically and strategically.

This time the focus is not simply launching another token, but building actual infrastructure and a differentiated ecosystem:

public testnet
blockchain/node software
explorer
desktop wallet in development
custom mining and difficulty model
open GitHub repositories

The long-term vision is also different. Picoin is designed around the idea of computational growth, scientific-oriented infrastructure and future distributed computing layers, instead of relying only on speculation or hype cycles.

Will it succeed? Nobody can promise that in crypto.
But I believe experience matters, and sometimes failed or incomplete projects are exactly what teach founders what not to do.

Today I have a much clearer understanding of architecture, infrastructure, community expectations and the importance of building something with its own identity instead of another generic fork.

Skepticism is healthy in this industry, so no offense taken. thanks

P.S.
Bug Report: New miners get "Commit rejected: invalid miner signature" on public testnet

Hi,

I just set up a miner on a fresh Ubuntu 22.04 VPS following the public testnet guide and ran into two issues that prevent mining from working out of the box. I wanted to report them so other new miners don't hit the same wall.

1. Missing dependency: pynacl

After running pip install -r requirements.txt, the pynacl library is not installed. Only cryptography is present. The miner starts, receives tasks, computes segments, but every commit is rejected with "invalid miner signature".

Fix: pip install pynacl

Suggestion: add pynacl to requirements.txt, or at minimum mention it in the public testnet README.

2. PICOIN_NETWORK defaults to "local" instead of "public-testnet"

In app/core/settings.py line 29:
NETWORK_ID = os.getenv("PICOIN_NETWORK", "local")

When a new miner runs without setting this environment variable, the client builds the commit signature payload with network_id="local" and the corresponding chain_id for the local profile. The server, however, verifies the signature using network_id="public-testnet". Since the payloads don't match, the signature verification fails — even though the cryptographic signing itself is perfectly correct.

This is the actual root cause of the "invalid miner signature" error for most new miners.

Fix: export PICOIN_NETWORK=public-testnet before running the miner.

Suggestion: either change the default to "public-testnet" in settings.py for the current phase, or add PICOIN_NETWORK=public-testnet to the .env.miner.example and the public testnet README as a required variable. The current README does mention it inside the large env block but doesn't flag it as critical.

Environment:
- Ubuntu 22.04 LTS
- Python 3.10
- Protocol version 0.18
- cryptography 44.0.0
- Commit that was tested: current main branch as of May 24, 2026

After applying both fixes, mining works perfectly — blocks are accepted and validated.

Thanks for building this project. Happy to help test further.

[johannFac]

Thank you for the detailed report and for taking the time to test the public testnet seriously.

You are absolutely correct on both points.

Missing pynacl

This dependency was unintentionally omitted from requirements.txt during recent refactoring and internal testing because some local environments already had it installed globally. We will add it immediately to avoid fresh miner setup issues.

PICOIN_NETWORK defaulting to "local"

Excellent catch.
The miner signature payload includes the network_id, so if the environment variable is not explicitly set to public-testnet, the generated signature payload differs from what the validator expects. As you correctly identified, the cryptographic signing itself is valid — the mismatch happens at the payload/domain level.

This is indeed the primary reason why some new miners experience:

Commit rejected: invalid miner signature

We will improve this in the next update by:

adding clearer setup instructions
improving .env examples
adding startup validation checks
and possibly changing the default network behavior during the public testnet phase

Reports like this are extremely valuable because public testnet exists precisely to identify real-world onboarding and infrastructure issues before mainnet.

Glad to hear mining is now working correctly on your setup. Thanks again for contributing and helping improve Picoin.
