I'll be waiting for the windows wallet for the genesis block 0 mainnet

Mainnet 16 Jan 00:01 UTC.

Cool thanks for update

[bitmonero]

switch to the mainnet at Jan 16 21:00 UTC

stop the node.
rm old data.
run the command without peers (will use default peers from the code)

./build/Darwin/master/release/bin/monerod \
  --data-dir ~/.monero-newnet-main \
  --no-igd --disable-dns-checkpoints --check-updates disabled


if you already generated wallet for testnet it is compatible for the mainnet as well. you can reuse or create the new one.

mainnet time scheduled for 16 Jan 21:00 UTC.

Testnet was a great preparation to really do it without premine.

cool dude, miss lady x random, satoshi

[bitmonero]

Monero Genesis Nonce.

uint32_t const GENESIS_NONCE = 10000;

Anyone who set it may be able to mine blocks way before network goes live because it is simply predefined number

BitMonero set the the numbers from last bitcoin block that will be known only after 21:00 UTC TIME 16 Jan 2026

[bitmonero]

Summary.

The mainent schedule for 21:00 UTC.

Fair launch without premine.
GENESIS_NONCE is not hardcoded anymore.

It is numbers from block hash of bitcoin that only will be known at 21:00

No one able to start mining solo and mine 1000 blocks locally before the actual start date.
You need to know genesis hash of last bitcoin block at 21:00 16 Jan 2026.

No one knows it.

This is the main difference between monero and bitmonero.

Monero has a hardcoded 10000 genesis nonce.

Bit monero is bitcoin fair start and tokenomics with a monero privacy.

[bitmonero]

Fair Launch: “Unknown Genesis Nonce” (Bitcoin-anchored)

To make the launch fair and prevent any premine / early mining, our genesis block cannot be fully known before launch time.

So we don’t choose the genesis nonce ourselves.

Instead, we derive it from a future Bitcoin block that nobody can know in advance.

The rule (simple)

We publicly announce a fixed cutoff time:
16 Jan 2026, 21:00 UTC (exact date/time is fixed and published before launch).

After that moment, we take the first Bitcoin block mined at or after 21:00 UTC
(not “any block we like” — strictly the first one after the cutoff).

We take that Bitcoin block’s hash (the 64-character hex string everyone can see).

From the hash, we build a decimal string by keeping only digits 0–9
(we simply remove letters a–f).

To stay compatible with C++ uint32_t, we take 9 digits and convert to an integer.
(9 digits always fit: max is 999,999,999 which is below uint32_t max.)

That number becomes the GENESIS_NONCE.

Why this is fair

Before the cutoff time, the nonce is impossible to know, because the Bitcoin block hash doesn’t exist yet.

After the cutoff time, the nonce becomes public and verifiable by everyone.

Developers cannot secretly mine early, because they can’t predict the exact Bitcoin block hash.

Quick example (concept)

Bitcoin hash (hex): 000000...7c6298855d...
Keep only digits → 762988556918...
Take 9 digits → 762988556
That becomes the genesis nonce.

How will mining be done? Can you share an example of this before the mainnet? I will activate and deactivate it depending on the situation.

git pull(after 21:00 UTC or set up the genesis nonce by ourself in the source code) this need to avoid premine by anyone. unkown genesis nonce -> uknown genesis -> impossible to premine.

genesis nonce is X first digits from bitcoin block hash at or after 21:00 UTC. but how many digits we should get from the hash? 9 or 10?

[bitmonero]

Bitcoin hash (hex): 000000...7c6298855d...
Keep only digits → 762988556918...
Take 9 digits → 762988556
That becomes the genesis nonce.

10 digits if it less then c++ int max 4294967295
9 digits if 10 digits more then c++ int max 4294967295

example
7294967295 > 4294967295

so genesis nonce is 729496729

example
3294967295 < 4294967295
so genesis nonce is 3294967295

that said no one knows this number yet and no one able to premine anything before the actual mainnet launch at 21:00 UTC time.


Real example:
https://blockstream.info/block/000000000000000000007c6298855d6918572654fa8b2ffeb67158962a885d2c

2026-01-16 10:39:05 UTC


Bitcoin hash (hex): 000000...7c6298855d...
Keep only digits → 762988556918...
Take 9 digits → 762988556. because it is bigger then max c++ int 4294967295
That becomes the genesis nonce.


genesis nonce will be inserted in the source code.

be ready for the bitcoin block at 21:00 UTC Jan 2026.

lol, do you know that "bitmonero" was actually the first name from monero and they changed it later to monero ? :-)

I remember. As an old ninja, this coin is now on my radar
Lets fire up the supernova!

good to hear.
Mainnet in 4 hours.
21:00 UTC time.

Fair launch. everyone is preparing to know genesis nonce based on bitcoin hash block at 21:00 UTC.

I've tried many things but I can't build it.
