[ANN] CivicNet (CIVIC) | Hybrid PoW+PoS Live Now , ASIC-Resistant | CPU Mining

Is there something wrong with version 3.0.1? The mining process is no longer functioning properly.

Could you share more details so we can help?

- What OS are you mining on (Windows/Linux)?
- Are you solo mining or on a pool?
- What exactly happens,miner won't start, connects but no shares, crashes, or something else?
- Any error message in the miner console or node debug.log?

Also worth noting: Hybrid PoW+PoS activated on mainnet earlier today, so if you're seeing fewer PoW blocks than before, that's expected, some blocks are now being produced by stakers instead of miners (currently ~5% of blocks). Mining itself should be working the same as before though, let us know what you're seeing and we'll dig in.

I am the Windows 3.0.1 client. The block synchronization has stopped at 20690. Has the node been changed? Are there any new node IPs?

I have the same problem as well.

No, the node/IPs haven't changed. Timing lines up with a pool/stratum crash-loop bug we hit on our end around that time (fixed a bit later) — that's the most likely cause of the stall, not your client.

JSON-RPC call failed: Block decode failed
[2026-08-09 09:43:44] submit_upstream_work json_rpc_call failed

 Same likely cause — our stratum server was crash-looping around then, which would explain failed work submissions.

Both should be resolved now. Also, we just pushed an updated Windows Qt Wallet build (same release, same file name) with a separate staking-loop fix — worth re-downloading and reinstalling: https://github.com/CivicLight/CivicNet/releases/tag/v3.0.1

Let us know if you're still seeing issues after updating/reconnecting.
Also, for faster updates on stuff like this going forward, might be worth joining our Telegram Channel/Community, we usually post there first when something's up.

Is there any specific reason of having 5% PoS ratio rather than 50%?
It seems more likely to have 50% each for PoW and PoS usually in other coins, although I may be wrong.

Any chance of having a Discord channel that is easier to reach/communicate for most people?
And also any change to fix the explore to show network connections? That will be useful to see how big the CivicNet.
Also good to add checkpoints time to time to the core.

1. There seems a subtle problem in PoW difficulty calculation or consensus after introducing PoS. The difficulty keeps going higher even though mining time is way longer than the expected block time 60 seconds. In long term, this may lose the expected quick transactions within 1 min in CivicNet.

2. It seems PoS cannot include Tx from mempool. Is there any specific reason of that design?
If PoW and PoS both can clear transactions than CivicNet can support faster transaction speed.

The chain block time is way much slower after PoS was introduced.
I think originally the target block time was 60 seconds, but now it looks like 10 minutes. There seems sometimes no block was found for 2 hours.
Somehow this makes CivicNet less attractive.

Maybe there was adding another '0' somewhere by mistake so the calculation ended up 10x  of block time?  
I thought PoW+PoS is a unique feature but maybe in bad shape.
Maybe diff calculation should be done by average blocktime to keep as close to 60 seconds, but not sure that's in the plan and actually doable or not.

You're right that the current block intervals have become longer, but there was no intentional 10× change to the 60-second target.

The main reason is the significant increase in network hashrate and difficulty after the PoS introduction. When network conditions change faster than the current difficulty adjustment can compensate, longer PoW intervals can occur, including occasional extended gaps.

The 60-second value remains the target block time. PoW + PoS is still the intended hybrid consensus design, and I'm monitoring the difficulty adjustment closely to improve stability as the network grows.

Thanks for pointing it out — it's something that needs to be tuned as the real-world network conditions develop.

Just a heads-up in case you haven't seen it - Gatevia currently has a 1st Anniversary promotion for new coin listings.

Native PoW/PoS/Hybrid listings are 99 USDT instead of 200 USDT, and additional pairs are 15 USDT instead of 30 USDT.

Not trying to promote anything here, just thought I'd mention it since your project might be looking at exchange listings.

This is how a project builds real reach — not one big moment, but stacking wins one at a time. Pools live. Wallets shipped. Now trackers picking us up.


Blockspot.io:

https://blockspot.io/coin/civicnet-civic/


If you've been holding CIVIC since the early days, this is the kind of moment that makes it worth it. More eyes, more exposure, more growth.

The grind continues. Let's keep building. 🔥

🚨 IMPORTANT UPDATE — v3.0.3 🚨

Big one for anyone running a node, mining solo, or on the desktop Qt wallet.

We found and fixed a follow-up bug in the PoW difficulty retarget logic — specifically about how fast blocks get found after the network switches between PoW and PoS.

The problem
Every time a PoW block landed right after a PoS block, the difficulty calculation was grabbing a stale, inherited value instead of computing from the real PoW history. Result: block times bouncing around unpredictably instead of settling near the 60s target.

The fix
Rewrote the retarget base logic (bnNew-base) so it always walks back to the last genuine PoW block's difficulty — no more borrowing stale values from PoS blocks. Combined with the existing retarget window fix, this means noticeably faster, more consistent block-finding across the board.

The safety net
This fix has its own dedicated activation timestamp — it does NOT apply retroactively to already-mined blocks. Clean switch-over, no chain drama.

Activation: 2026-08-17 06:00:00 UTC

If you run a full node, solo mine, or use the desktop Qt wallet — please update before activation to stay in sync with the network:

https://github.com/CivicLight/CivicNet/releases/tag/v3.0.3

Pool miners (own pool, NitroPool, RabbitMiner) — you don't need to do anything, your pool operator handles this.

More consistent blocks, more consistent rewards. Let's go. ⛏️🚀

After adjusting PoW difficulty recently, now it shows the blocktime is close to a few seconds and averaging less than 30 seconds.
So still something seems not right as it's not fully calibrated to 60 seconds yet.
Some more fix seems needed to properly mix PoW+PoS in better shape
