[Opacra @opacra_org]

Opacra mainnet is live.

Your node is synced and working, It just isn’t mining yet. Either:
1: type in that window: start_mining YOUR_Pa_ADDRESS 4 (4 = CPU threads), or
2: close it and double-click Start Opacra mainnet instead. It creates a wallet and starts mining automatically.
Tip: solo mining can take a while per block. For steady payouts, use the pool (guide at https://t.co/hXgCpKdQgm)

Your node is working perfectly. synced and mining at ~4.7 kH/s. Solo means you only get paid when you find a whole block. At your speed that’s ~2–3 blocks a day on average, but luck can mean hours with none. For steady, smaller payouts, mine to the pool instead: https://t.co/yggmFqQoDH (guide at https://t.co/hXgCpKdQgm) ⛏️

Halo! File-nya aman 🙏 Windows Defender salah mendeteksi karena program ini berisi kode mining (false positive yang umum untuk semua software mining). Kami sedang melaporkannya ke Microsoft.

Kalau mau lanjut sekarang: buka Windows Security → Virus & threat protection → Protection history, pilih deteksi file Opacra → Actions → Allow on device, lalu download lagi. Setelah itu cek file-nya dengan perintah hash di https://t.co/hXgCpKdQgm. Harus muncul “OK”.

Jangan matikan Defender sepenuhnya. Cukup izinkan file ini saja.

(EN: The files are safe. Defender flags them because they contain mining code, a common false positive. We’re reporting it to Microsoft. To continue now: Windows Security → Protection history → the Opacra detection → Allow on device, download again, then run the hash check from https://t.co/hXgCpKdQgm. Don’t turn Defender off; only allow this file.)

@BitSatsY No mobile app yet, Mining needs a desktop or laptop CPU, and the wallet is on Windows (Linux from source) for now. A mobile wallet is something we’d love to do later, but no date yet, and we won’t promise one until it’s real.

[Opacra @opacra_org]

Nope, nothing to do with Nethxeum, we’re a completely separate project. The wallets look alike because both are built on the open-source Monero wallet, and loads of coins use it. Opacra has its own chain, its own mining algorithm and its own dev fund. Everything’s on our GitHub if you want a look.

@kkji_w Thanks for mining, glad to have you! We don’t give listing timelines and won’t set or predict a price. That’s for the market to decide. Any listing will be announced on our official channels only once trading is actually live. Until then, beware of anyone claiming otherwise.

Thanks for flagging. Windows Defender is flagging our node because it includes a built-in CPU miner, a common false positive for mining software. We’ve reported it to Microsoft. Until it clears, check the download against the signed SHA-256 on our GitHub release, or ask in Discord.

[Opacra @opacra_org]

Thanks for sharing Opacra, and great to see people mining it. A fair launch for everyone: no premine, no presale, no token sale, full rewards from block 1. The code is open source, every release is signed, and the dev fund's view key is public so anyone can check it. Happy mining, and welcome!
