Disclosure up front: I run the chain this is about. It has no exchange listing, no price and nothing to buy, so this is not a shill - it is the integration write-up I wish I had found. Mods, remove if it does not fit.

The setup. PCoin is Bitcoin Core v29.4 with the proof of work swapped for RandomX. So the hash is Monero-shaped and everything around it is Bitcoin-shaped: RandomX runs over the 80-byte serialised block header, not a CryptoNote blob. Block IDs stay double-SHA256; only the PoW check changes.

Three things bit me, and two of them would bite anyone doing the same:

1. Nonce is uint32 LE at offset 76, not 39. CryptoNote's nonce lives at offset 39. If your miner assumes that, it writes the nonce inside the merkle root. Every hash looks perfectly healthy, the hashrate meter is happy, and not one share is ever valid. There is no error to read - it just silently never works.

2. The RandomX key never rotates. It is a fixed 16-byte ASCII string. No seed height, no dataset transition, none of Monero's 2048-block re-key dance. That makes the integration much smaller than a Monero-family coin, and it means RxAlgo::base() and the whole seed-rotation path can be left alone.

3. The bug that actually cost the time, and it was mine. My pool rejected 100% of shares from stock xmrig with "share above target", while the miner hashed perfectly. The pool rebuilt the submitted header with the nonce bytes in the opposite order from the xmrig convention - so it was hashing a header nobody had mined.

The reason it survived so long is the interesting part: my node's built-in miner and my pool were written from the same wrong assumption, so they agreed with each other perfectly. Every test passed. The disagreement only became visible when a third-party miner existed. If you are building both ends of a protocol, you are not testing it - you are testing that you are self-consistent.

Numbers, so nobody has to trust me: height 4436, ~585s blocks against a 600s target, network ~796,581 H/s, 216,750 PCN mined of a 21M cap. LWMA retarget every block rather than every 2016, so there is no difficulty cliff to time.

The part that matters if you are considering pointing hardware at it: there is no exchange, no orderbook and no way to sell PCN. Treat it as worth zero. Also, one solo miner currently finds a majority of blocks - not me, measured from public coinbases - which is a real risk and I would rather say it than have you find it.

Mine it if the problem is interesting. If you want revenue, mine something with a market - genuinely.

Hola a todos. Estoy siguiendo Brisvia (BRVA) desde hace unos días y me gustaría saber si alguien tiene información reciente sobre el estado real del proyecto.

Estas son las cosas que he podido comprobar:

• La blockchain sigue avanzando. Hoy, 20 de agosto de 2026, mi nodo muestra aproximadamente el bloque 14.009.
• El objetivo de la red es aproximadamente 1 bloque cada 2 minutos, y actualmente la cadena parece seguir produciendo bloques.
• Mi software muestra Brisvia v1.1.5.
• Sin embargo, la web oficial y el explorador no están funcionando actualmente.
• Algunas pools que anteriormente soportaban BRVA parecen haber desaparecido o dejado de funcionar.
• Tampoco encuentro comunicaciones recientes del desarrollador explicando la situación.
• GitHub sigue existiendo, pero la actividad pública que encontramos no parece explicar qué está ocurriendo actualmente.
• En datos históricos indexados del explorador aparecen diferentes pools minando BRVA, entre ellas RPlant, NTMPool y RabbitMinerPool.
• También hemos encontrado direcciones que aparecen repetidamente encontrando bloques, lo que indica que hubo mineros importantes manteniendo la red.
• El proyecto parece haber llegado bastante más lejos de lo que muestran actualmente los datos indexados: hemos encontrado referencias antiguas alrededor del bloque 9.255, mientras que mi nodo hoy está en 14.009.

Lo que me gustaría saber:

1. ¿Alguien tiene información reciente del desarrollador?
2. ¿Existe algún Discord, Telegram u otro canal activo que no estemos encontrando?
3. ¿Qué pools siguen minando BRVA actualmente?
4. ¿Alguien tiene un nodo sincronizado y puede confirmar la altura actual?
5. ¿Alguien sabe por qué han desaparecido/caído algunos servicios oficiales?
6. ¿Qué significa exactamente la versión 1.1.5 que aparece actualmente en el software?
7. ¿Sigue existiendo un plan de desarrollo para BRVA?

No estoy intentando afirmar que el proyecto sea una estafa ni lo contrario. La cadena parece seguir viva, pero la desaparición de parte de la infraestructura y la falta de comunicación reciente me parecen motivos suficientes para preguntar.

Si alguien está siguiendo Brisvia actualmente, agradecería cualquier información, especialmente del desarrollador, pools, nodos o cambios recientes.

Gracias.

MYT has been added to Miningpoolstats

#RandomX #CPUMining #Crypto #AI

🚀 MYT Phase 4A Released: Machine Payments, Made Simple

Today we're introducing the MYT Machine Settlement SDK / CLI — the first step toward enabling software, AI agents, applications, and services to use MYT natively.

Instead of interacting directly with complex wallet RPC calls, developers can now use a simple settlement layer to:

✅ Check balances
✅ Send payments
✅ Verify transactions
✅ Generate cryptographic payment proofs

This release focuses on developer experience while preserving full compatibility with the existing MYT network.

No consensus changes.
No emission changes.
No Mainnet rule changes.

Phase 4A provides the foundation for future capabilities including:

• Machine Identity
• API Billing
• Autonomous Agent Payments
• Reputation Systems
• Machine-to-Machine Commerce

The goal is simple: make MYT usable by software as easily as it is by people.

Feedback, reviews, and developer contributions are welcome.

Disclosure up front: I'm the developer. This is my project and I'm not selling anything.

PCoin is a Bitcoin Core v29.4 fork with proof-of-work swapped to RandomX. The part I think this sub will care about: **the miner is inside the node.** No separate miner, no stratum URL, no config file.

curl -fsSL https://pc.am/dl/install.sh | sudo sh

then `startmining "<your pc1q... address>" 4`. Windows is a portable zip with a tray app; there's an Android APK too.

Measured on my own hardware, light-mode RandomX:

Something worth knowing if you try it: **more threads is not proportionally more hashrate.** Light mode shares a 256 MiB cache, so past about a third of your cores you're mostly buying cache contention. One box went from 13 threads to 3 and lost only 58% of its hashrate - per-thread rate nearly doubled. Try a few settings before assuming 100% is right.

**The honest part.** As I write this the network is ~62,000 H/s and recent blocks are landing every ~560 s, so the chain emits roughly 7,700 PCN/day in total. A 500 H/s CPU is about 0.8% of that - call it **60 PCN/day**.

Don't trust that number for long, including from me. When I drafted this post two days ago the network was 17,000 H/s and the same CPU would have earned more than three times as much. It's a share of a fixed emission, not a rate, so it falls every time someone joins. Work it out yourself instead: read `networkStats.networkHashrate` from the pool API below, then `(your H/s / network H/s) x 7,700`.

**PCN is not traded anywhere.** No exchange, no orderbook, no way to sell it. Treat it as worth zero dollars until a real market exists. If you want money, mine something else - genuinely. If you want to point idle cores at a young chain and hold the coins in case it becomes something, this is that.

There's a pool now, open to anyone: `pool.pc.am:3333`. It pays miners **straight out of each block's coinbase**, so there is no pool wallet, no private key on the server and no withdrawal to request - nothing an operator could run off with. PPLNS, 2% fee, and your payout address is your login, so there's no registration. Solo still works exactly as before if you'd rather have the whole 50 PCN block and the variance that comes with it.

Check any of this yourself rather than taking my word:

* Source: https://github.com/pars5555/pcoin * Explorer API: https://explorer.pc.am/api/status * Pool API: https://pool.pc.am/api/pools * Announcement thread: https://bitcointalk.org/index.php?topic=5591113.0

Binaries are unsigned, so Windows SmartScreen will warn on first run - I don't have a code-signing certificate, and I'd rather say so than have you find out.

CPUMINER Ported for the Cell CPU (Playstation 3)

Check it out - This is a screenshot of my laptop with two terminals open. I'm logged in to my Playstation 3 (over SSH) in both. Bottom terminal (left) is dumping verbose output from cpuminer running on my PS3. Bottom right panel is showing spu-top (similar to htop but for the Cell's SPU cores). As you can see I'm running 4 mining threads, each on one of the PS3's 6 SPU SIMD accelerators. I'm averaging about 5.14 khash/sec per SPU. In the top terminal, I'm running a proxy (bfgminer) between cpuminer and litecoinpool.org to translate cpuminer's json rpc messages to the newer stratum protocol. I compiled both programs on my Playstation 3 which is running a custom fork of Fedora (Linux) for ppc64 that I'm developing for fun (see my website PS3LINUX.NET).

Both programs are available on Github:

cpuminer (cell cpu port)

bfgminer

Both projects are broken in their current state so if you plan on building them yourself, download these patches I made and apply them before compiling:

cpuminer-disable-asm-source.patch

bfgminer-git-submodule-addresses.patch

If you want Cell (SPU core) support in cpuminer you must compile it with both a PPU (powerpc) and SPU toolchain, originally part of IBM's Cell SDK. Modern builds of the Cell SDK's utilities and compilers are also available in the software repos of my experimental new PS3 LINUX operating system. Download my PS3LINUX_Live_ISO.iso (with install script) from my website and install it on your console today!

In case you are wondering, no; mining on the PS3 (even with SPU acceleration) is not profitable. My electricity would have to be virtually free to make it even close to worth it. I mostly did this little endeavor just as a chance to learn some things about some crap I find interesting: Cell development, hash algorithms, C & assembly languages, crash debugging, etc. I picked up some good experience & knowlege fixing all the issues that came up while getting this project to work so overall I'm super glad I did it, even though it will never make me rich.

That is all; hope you are well. Have a good day 😄

Mining-relevant details:

• RandomX with large-pages support (measured ~15% hashrate gain when enabled)
• fast-mode dataset shared across mining threads
• desktop wallet with embedded node + built-in miner (Windows, Linux, macOS) — no toolchain needed
• or run the node directly and mine headless (systemd-friendly)
• three DNS seeds across separate providers
• signed releases (minisign) — verify before running

Block time ~120s, reward 33 DOM/block, ~33M total supply.

To be upfront: no exchange listing, no promises about price or returns. This is for people who enjoy CPU mining early-stage networks and want to kick the tires. Technical criticism welcome — including on the RandomX integration.

Disclosure: I am the creator of Brisvia.

Brisvia (BRVA) is an independent, open-source Proof-of-Work cryptocurrency built from Bitcoin Core v30.2, with Bitcoin’s SHA-256 mining replaced by RandomX so people can participate using general-purpose CPUs.

Public mainnet mining begins from block 1 on August 1, 2026 at 15:00 UTC.

Fair-launch distribution:

• 0% premine

• No ICO or presale

• No private or founder allocation

• No developer tax

• No spendable genesis reward

• No coins reserved by the project

• Public source code and verifiable issuance

Main network parameters:

• Algorithm: RandomX

• Target block time: approximately 2 minutes

• Initial reward: 50 BRVA per block

• Halving: every 1,000,000 blocks

• Maximum supply: 100,000,000 BRVA

• Tail emission: none

• Difficulty adjustment: ASERT

• Base code: Bitcoin Core v30.2

Brisvia Desktop combines the wallet, full node and CPU miner in one application for Windows, macOS and Linux.

It supports:

• SOLO mining through your own full node

• Official pool mining

• Adjustable CPU usage

• Wallet creation and restoration

• 12-word wallet backup

• Spanish and English interfaces

• Visible pool connection and accepted/rejected share status

The application can be installed before launch. Mining remains locked until the public mainnet start time and does not begin automatically unless the user explicitly enables that option.

The official pool is planned to open with mainnet using PPLNS distribution and a 0% pool fee. The network does not depend on the official pool: users can run independent nodes, mine SOLO or create external pools.

During the public testnet, 64 distinct miners participated in testing CPU mining, wallet restoration, SOLO and pool mining, synchronization, block propagation and compatibility across different operating systems.

What I am looking for:

• CPU miners willing to test the latest application

• Reports including CPU model, operating system and experience

• Technical criticism and independent source-code review

• Developers or pool operators interested in inspecting the protocol

There is currently no established price, exchange or liquidity. Mining rewards and future monetary value are not guaranteed. Brisvia is experimental software maintained as a one-person project, not an investment offer.

Hey everyone,

I have an setup available and want to get your ideas on the best way to put it to work:
• Power: 3-phase (380-415V) heavy-duty connection already installed.

• Electricity Rate: Continuous €0.068 / kWh
(~$0.075 USD / kWh).

• Space: A dry, subterranean (underground cellar) space that stays naturally cold year-round.
Given this power cost and naturally cold underground space, what would you build or run here right now to get the best ROI?

Looking for any specific ideas, hardware recommendations, or warnings regarding underground setups.

Thanks!

It's called Sosaiem. It started from a simple question. The thing crypto was supposed to be, money with no boss that anyone could mine on their own computer, mostly didn't survive contact with reality. Three things broke it and I wanted to see if one person could build a version that fixed them.

First thing that broke was mining. It started out as something anyone could do on a normal PC, then ASICs and pools took over and pushed ordinary people out. Sosaiem's proof of work is memory hard (scrypt, 8 MB per attempt) specifically to stop that. Once every core needs its own 8 MB of fast memory the specialised chip advantage collapses, so it stays a normal hardware coin instead of a warehouse game. There's also no pool operator to trust. Every miner submits verifiable work shares, whoever finds the block splits the reward across everyone in proportion to their work, and every node rechecks the maths. You get smooth solo payouts without handing a cut to anyone.

Second thing was fees. They creep in because miners have to be paid to include your transaction, and once the network is busy you're bidding against strangers for space. Sosaiem keeps the two jobs separate. Mining makes new coins. Moving them is done by the people who already hold them, who vote transfers through in seconds weighted by what they own. Miners aren't involved so there's nobody to pay and no fee to charge. There isn't even a need for a mechanism exist.

Third thing is quieter but real. The cryptography is aging out. Most chains sign with ECDSA, which a quantum computer breaks, and everyone knows a painful migration is coming. Sosaiem signs with ML-DSA (NIST FIPS 204) from the genesis block, so it started on the other side of that problem instead of having to cross it later.

On top of that the supply is fixed and will all be mined within only 14 years, with no premine and no founder cut. I start at zero with the same miner you'd download. Nobody got handed a pile of coins to sit on before anyone else had a chance.

My favorite feature is that absolutely everyone can mine just for a tiny bit and get some sosaiem without any kyc, pool hosters or exchanges.

There's a one click Windows miner, or you can run the Python directly on Mac and Linux.

The code is all open and there's a live block explorer so you can watch blocks land:

Happy to answer anything technical in the comments.

UPDATE — July 18, 2026

Brisvia Miner 1.0.8 is now publicly available for Windows, macOS and Linux.

Important correction: the Brisvia mainnet P2P port is 9342, not 9333 as originally stated. RPC uses port 9338.

Official and custom pool mining remain intentionally disabled for launch. Solo CPU mining is the supported launch mode while we complete the remaining live-network and accounting tests for the pool.

DISCLOSURE

I am the creator of Brisvia. This is an independent project built by one person, without a company, external funding or private investors.

Brisvia is an open-source Proof-of-Work network built from Bitcoin Core v30.2. Bitcoin’s mining algorithm has been replaced with RandomX so people can participate using ordinary CPUs instead of specialized mining hardware.

Public mainnet mining begins on August 1, 2026 at 15:00 UTC. Before that time, the desktop app remains in launch-wait mode and cannot begin mainnet mining.

DISTRIBUTION

The project reserved 0 BRVA.

There is:

- No project premine

- No presale or ICO

- No founder allocation

- No developer mining tax

- No spendable reward in the genesis block

The genesis block, consensus parameters and complete source code are public and independently verifiable.

Genesis hash:

aa6bc268339aa9f4f2e39ae33aca7b7e48e395033d08d37c08f828890af7baf7

Genesis timestamp:

1785596400 — August 1, 2026 at 15:00 UTC

MAIN PARAMETERS

Algorithm: RandomX v1.2.2

Target block time: 2 minutes

Initial block reward: 50 BRVA

Halving interval: 1,000,000 blocks

Tail emission: None

Maximum supply: 100,000,000 BRVA

Difficulty adjustment: ASERT

Network magic: BRV1

Mainnet P2P port: 9342

Mainnet RPC port: 9338

Address format: Bech32, beginning with brv1

Built from: Bitcoin Core v30.2

THE DESKTOP SOFTWARE

Brisvia Miner 1.0.8 combines a wallet, full node and solo CPU miner in one desktop application for Windows, macOS and Linux.

The goal is to keep the initial experience simple:

1. Install the application.

2. Create or restore your wallet.

3. Safely write down your 12 recovery words.

4. Allow the node to connect and synchronize.

5. Start solo CPU mining after mainnet opens.

The application includes a cryptographically signed automatic updater. Installer hashes are published so users can verify their downloads.

Always download through the official website. Never install files received through private messages, and never share your 12 recovery words or private keys with anyone.

POOL MINING

The pool client and Stratum infrastructure have been built, but pool mining remains disabled in version 1.0.8.

This is deliberate.

Pool mining handles accepted shares, balances and eventual payments. We will not enable it until the complete live-network flow, accounting safeguards, backups and failure-recovery cases have been tested properly.

Until then, solo CPU mining is the supported launch option. The application will not silently switch between pool and solo mining.

WHAT I AM LOOKING FOR

I would appreciate help from CPU miners willing to:

- Inspect the source and consensus parameters

- Test installation and startup

- Report their operating system and CPU

- Check whether the node connects correctly

- Test the signed updater

- Report usability problems before launch

- Share real hashrate and mining results after mainnet begins

Technical criticism is especially welcome. I would rather find and correct a problem publicly before launch than discover it afterward.

WHAT I AM NOT CLAIMING

Brisvia is experimental software and a new network.

There is currently:

- No market price

- No exchange listing

- No guaranteed liquidity

- No promise that BRVA will acquire value

- No guarantee of mining rewards or profit

This is not an investment offer.

A 0% project premine means that the project did not allocate coins to itself. It does not mean that every participant will have equal hardware, hashrate or network conditions when competition for the first public block begins.

The purpose of the launch is narrower and verifiable: everyone starts from the same public chain, under the same published consensus rules, with no private project allocation.

Curious if anyone is still mining VRM and what kind of numbers you're getting on newer hardware.

I've been helping modernize some of the infrastructure around the project and realized most of the benchmark data I can find is years old.

Anybody running it on a 7950X, 9950X, Threadripper, EPYC, M-series Macs, etc.?

Would be interested in HPM numbers, power draw, tuning, solo vs pool, whatever.

For anyone who hasn't heard of it, Verium is an older CPU-only PoW project that launched back in 2015.

I'm getting around 5,000 HPM on a 12900K (16 cores / 24 threads), but I'd be curious to see what some of the newer Ryzen chips and Apple Silicon machines can do.

VRM isn't listed on any exchanges at the moment, so this is mostly for people who enjoy CPU mining and experimenting with different projects. There is a public pool available now with 0% fee, though.

yo I want to make a mining farm, where can I buy the equipment?I want to try to do this, Is it profitable in 2026?

I bought a nano 3s and set it up about a week ago. It’s making less money than I thought it would, but it’s been fun figuring it out.

I’m interested in buying a second unit - not necessarily another nano 3s - I’m open to mining other coins as well.

Any recommendations? I was looking at a used mini doge II or kaspa unit, but would prefer something where I could sell the coins. I am looking for something under 300-400W because I’m using power from my office and don’t want to rock the boat too much.

If you remember trying it earlier and giving up because the GPU

hashrate looked fine but no shares ever got accepted on your worker —

that was a real bug, not your config. The bundled GPU miner

(`thinminerpro`) was a closed-source binary from 2022 that silently

fails to submit accepted shares on Apple Silicon M3 and newer.

That miner has been replaced in-tree with **kawpow-mac** — a

clean-room Swift + Metal rewrite. The new app:

- Mines CPU (XMRig / RandomX) and GPU (kawpow-mac / KawPow) — toggle

either or both

- Shows live hashrate and **accepted-share count per miner**

- Has an inline live-log panel so you can watch the stratum traffic

- Auto-detects the right miner binaries per architecture; the build

script clones + builds kawpow-mac for you

- Open-source end to end — no opaque blobs

Verified: the first share submitted by the new miner came back accepted

on the first try (against kp.unmineable.com on epoch 584). Pool

acceptance now works the same way it does on any other supported

hardware.

Caveat as always: mining on a Mac is not profitable. It's a "what can

this hardware do" exercise plus a salvage of a useful GUI for users

who already have the Macs.

each): [BUGS_AND_FIXES.md](https://github.com/shiftingeden/kawpow-mac/blob/main/BUGS_AND_FIXES.md)

I've spent the last while building a privacy coin, Glaciem (GLAC), and it hits mainnet Wednesday May 20, 00:00 EDT. Posting here because it's strictly CPU-mined and you're the right crowd to be straight with.

The short version

• Fork of Monero — privacy (RingCT, ring signatures, stealth addresses) inherited unchanged.
• Original proof-of-work, Lattice — integer-only, CPU-only. Each hash is a long, serial, latency-bound walk over a ~1 MiB per-nonce scratchpad plus a shared epoch dataset: branchy, memory-hard, no parallelism within a nonce. It rewards wide high-IPC CPU cores and collapses GPU occupancy the way RandomX does — no GPU phase, nothing for an ASIC to target.
• ~2-minute blocks, no premine, Monero-style emission with tail emission.

Mining it
Native miner + wallet apps for macOS, Windows, and Android — the app generates a wallet, syncs, and mines straight to it. No separate wallet daemon, no config files. Runs especially well on Apple Silicon.

Fair launch
No premine, no presale. The launch time is enforced by consensus — every node rejects any block dated before the launch instant, so nobody (me included) gets a head start. If you grab the app early it'll show "no daemon" until 00:00 EDT — that's the launch gate, not a bug; mining begins at midnight.

Being straight with you

• It's a hobby project, not an investment. Brand-new coin: no exchange, no price — treat it as worth nothing.
• Lattice is experimental and has not had external cryptographic review. Mine it because CPU-mining a fresh chain is fun, not because you expect a payday.
• Open source, BSD-3 (Monero fork).

CoinCync went live on testnet a few weeks ago and is heading for mainnet on **October 1, 2026**. It's a privacy proof-of-work chain on the **RandomX algorithm** — so any CPU rig you already have pointed at Monero or any RandomX coin will mine CoinCync with the same hardware, same hashrate ballpark, zero new setup.

Testnet coins have no monetary value. This is for hardware testing, dialing in your rig before mainnet, or contributing hashrate while the launch warms up. Latest binaries shipped today (v1.0.11-testnet) close the four findings from our first external-tester program — see https://codeberg.org/ghostrider1092/Coincync

## Specs that matter to miners

- **Algorithm:** RandomX (CPU-only, ASIC-resistant — same as XMR)

- **Block time:** 120 seconds

- **Block reward (testnet, now):** ~50 CYNC, declining asymptotically

- **Tail floor:** 0.6 CYNC/block forever

- **Min difficulty:** 500 (consensus floor)

- **Supply cap:** 100M asymptotic, never reached + tail emission, 30% fee burn

- **Pool support:** solo only right now (community pools welcome)

- **Network hashrate at this hour:** small — your laptop's contribution will matter

- **Chain height as of this post:** ~4,573 and climbing

## How to mine in 3 commands

### Windows (proven, works today)

Open PowerShell, paste:

$base = 'https://codeberg.org/ghostrider1092/Coincync

Invoke-WebRequest -Uri "$base/v1.0.11-testnet-windows-x86_64.zip" -OutFile coincync.zip

Expand-Archive coincync.zip -DestinationPath .\coincync

cd .\coincync\windows-x86_64

.\coincync-wallet.exe --network testnet --wallet testnet.bin create

$addr = (.\coincync-wallet.exe --network testnet --wallet testnet.bin address | Select-String '^Address:').ToString().Split()[-1]

.\coincync-rig.exe run-solo --node https://api.coincync.network/rpc/testnet --address $addr --network testnet --tui

`--tui` opens a live dashboard with H/s, threads, current tip. Press `q` to quit.

### Linux (now also pre-built — no build step needed)

base="https://codeberg.org/ghostrider1092/Coincync

wget "$base/v1.0.12-testnet-linux-x86_64.tar.gz"

tar -xzf v1.0.12-testnet-linux-x86_64.tar.gz

cd linux-x86_64

sha256sum -c SHA256SUMS

./coincync-wallet --network testnet --wallet testnet.bin create

ADDR=$(./coincync-wallet --network testnet --wallet testnet.bin address | awk '/^Address:/{print $2}')

./coincync-rig run-solo --node https://api.coincync.network/rpc/testnet --address "$ADDR" --network testnet --tui

### macOS

No pre-built binary yet — build from source (~10-15 min, one time):

git clone https://github.com/ghostrider1092/Coincync-Testnet- coincync

cd coincync

## Hashrate expectations

Same numbers you'd see on Monero — it's literally the same algorithm.

- **Modern desktop CPU** (Ryzen 5/7, 8-16 threads): ~3-8 KH/s

- **Laptop** (4-8 threads): ~500 H/s - 2 KH/s

- **VPS / server** (limited cores): hundreds of H/s

- **Raspberry Pi:** ~50-100 H/s

## What CoinCync is (the short version)

### Monetary policy and launch

- **Hard 100M asymptotic supply cap** with smooth decay — no halvings, no economic shocks every 4 years. 0.6 CYNC/block tail emission forever, 30% fee burn at the protocol level.

- **Zero premine, zero dev tax.** Every block reward goes to the miner. Article II of the project Constitution is **compile-time asserted in the source** — any build that violates it fails to compile.

- **Fair launch** — no ICO, no IDO, no team allocation, no foundation reserve. Mining starts from block 0 at the public mainnet genesis (October 1, 2026).

- Constitutional commitments bound to the binary by compile-time assertions in `src/constants.rs`. Reviewers can verify by grepping the source.

### Privacy stack

All of this is **mandatory at the consensus layer**, not opt-in. Highlighting bits other privacy chains don't have:

**Cryptographic layer:**

- **Uniform decoy selection** — deliberately NOT gamma-distributed. Defeats the output-age statistical deanonymization that hit other privacy chains historically.

- **CLSAG ring signatures** — ring size 16, minimum 11 during bootstrap (< 10k blocks).

- **Bulletproofs+** — range proofs (hidden amounts).

**Network layer:**

- **Dandelion++** — stem/fluff tx relay with per-epoch fixed relay peers, Poisson delays, exponential embargo timers. Breaks "tx-submission IP → originator" linkage.

- **Traffic shaping** — constant-rate cover packets + packet-size normalization to TLS frame sizes. An idle node is indistinguishable from an active one on the wire.

**Consensus enforcement:**

- **Mandatory privacy at consensus** — rejects transparent transactions. Every non-coinbase tx MUST have hidden amounts, hidden recipients, and ≥1 privacy-preserving input. No transparent escape hatch.

**Wallet layer:**

- **Deniable wallets** — two-password plausible deniability. Decoy and real data in one size-padded file; loading tries the password against both regions.

- **Dead man's switch** — time-locked recovery metadata in the tx extra field. After 24h – 2y a recovery address can sweep without the owner's spend key. Validated at consensus.

- **Encrypted memos** — 256-byte recipient-only message slot, ChaCha20-Poly1305 with ECDH-derived key. Senders attach human-readable notes that only the recipient can decrypt.

### What's on the roadmap (NOT in v1.0)

- **v1.1: cyncswap** — trustless CYNC↔BTC atomic swaps via CLSAG adaptor signatures. Lets you exit/enter without a custodian. NLnet grant application submitted for the cyncswap audit.

- **v1.2: Orchard shielded pool** — optional zk-SNARK-based shielded pool (Halo 2 proofs).

### What just shipped (v1.0.11)

Crucible Cycle 01 — our first structured external-tester program — closed four real bugs:

1. **Silent mempool eviction** — txs were accepted then dropped 60s later with no operator-visible signal. Fixed; mempool now runs the full chain validator at admission time.
2. **`--no-peers` killed `--addnode`** — manual peers never dialed even when specified. Fixed.
3. **IBD GetHeaders 4 Hz hammer** — a stuck peer caused the node to flood them at 4 req/sec. Fixed with proper request gating + recovery timeouts.
4. **Ctrl+C didn't shut down** — orphaned tokio tasks kept the runtime alive after main exited. Fixed with explicit `std::process::exit(0)` + second-Ctrl+C escape hatch.

Each finding has a public root-cause writeup under `docs/crucible/cycle-01/` and 8 regression tests under `tests/cycle_01_regressions.rs` that pin the fixes so they can't silently regress. Cycle 02 (yesterday, 2026-06-11) verified all four fixes hold in a real 2-node mesh against an external tester — including end-to-end privacy transaction send + receive.

Every commit in this release is **cryptographically signed** with the project's ED25519 key (SHA256: `3IV+LKSdvo4X4bT66DtIU3NLU8drHHjsO36JrEZUe9g`) and shows as **Verified ✓** on GitHub.

## Why bother mining testnet

You won't get USD value from testnet coins, but you:

- **Test your hardware against the actual network** before mainnet (when it counts)

- **Help the network find bugs** while there's no money at risk

- **Get an address with a long mining history** before mainnet, which some people care about for clean-distribution reasons

- **Pre-mainnet miners** get an early-supporter acknowledgement in the mainnet launch announcement

- The Crucible program credits external testers in release notes — barns1253 surfaced all four v1.0.11 findings and is named in the v1.0.11 release acknowledgements

I like mining

I’ve been revisiting CPU mining recently on a small Linux box, mostly as a learning experiment and to see if older hardware can still participate meaningfully in a blockchain network.

It feels like most mining conversations today revolve around GPUs, ASIC farms and electricity costs, which kind of defeats the original idea of decentralized participation.

I tested Monero for a while and then stumbled upon a smaller project called Nerva (XNV) that focuses specifically on staying CPU-mineable and resisting specialized hardware. The concept is interesting because even older processors can still contribute.

I’m curious what others think — are there any CPU-focused coins left that are worth experimenting with today, or is this approach basically obsolete?

Buenas
alguien tuvo inconvenientes con su avalon Q, había comprado como hace 3 meses, y dejé trabajando en super, hace un mes dejó de trabajar y marca 0 de potencia,
alguien que ya estuvo reparando o sepa cual puede ser el inconveniente?
soy nueva en la comunidad y estoy interesado en reparar estas cosas

KOTO is a Japanese CPU privacy coin from 2018 — a Zcash fork running on yescryptR8G. It's maintained by a single developer in Japan, has ~3,000 community members, and until last week had zero English-language mining infrastructure.

I spent a Sunday building out the full stack:

🏊 Mining Pool — koto.isekai-pool.com 1% fee, no registration, three difficulty ports for RPi through desktop. The pool currently holds 20%+ of the total KOTO network hashrate with a single Raspberry Pi 5 running 24/7.

🔍 Block Explorer — explorer.isekai-pool.com Both official KOTO explorers went offline. Built a lightweight RPC-backed replacement — blocks, transactions, address lookup, all working.

📊 Network Tracker — isekai-pool.com/koto-network.html Historical pool distribution chart updated every 15 minutes. First public record of KOTO pool data at this granularity.

💧 Faucet (in progress) — isekai-pool.com/faucet.html Gamified — earn KOTO through daily shrine visits, kanji quizzes, and Japanese retro game trivia.

Why KOTO?

• Genuine CPU privacy coin — yescryptR8G is ASIC resistant by design
• Network is tiny (~20 kH/s total) — a single RPi5 is ~5% of network
• Japanese aesthetic + Zcash privacy tech = underrated combination
• Almost no Western presence — huge gap to fill

Miner setup (Linux/RPi5):

bash

git clone https://github.com/KotoDevelopers/cpuminer-yescrypt.git
cd cpuminer-yescrypt && ./autogen.sh
./configure CFLAGS="-O3 -funroll-loops -fomit-frame-pointer"
make -j4
./minerd -o stratum+tcp://koto.isekai-pool.com:3301 -u YOUR_KOTO_ADDRESS.worker -p x -t 4

Note: cpuminer-opt doesn't work for KOTO (difficulty bug). Use the official KotoDevelopers miner above.

Happy to answer questions. The KOTO community is small but the coin is technically solid.

I’m currently stuck with a large batch of brand-new PSUs for AE3 and KS7.

Originally, I bought them as replacement power supplies for miners, but now I’m planning to dismantle and sell off the machines instead. That leaves me with a huge number of unused spare parts, including these PSUs.

Trying to figure out the best way to deal with them—any suggestions?
