Hello sers! Anyone here looking for developers or designers by any chance?

One solution is HD wallets (BIP32/44). It can generate many addresses from a single seed, & monitor them all by watching that xpub or address descriptor, using a bitcoin node or electrum server.

I want to make a tg bot so that the user enters his name and bitcoin wallet, and then receives the address to which the bitcoins need to be transferred, and as soon as he has transferred them, I should receive a notification about this.

Any UI/UX developer here interested in working with us on a bitcoin-only application?

Hi! I'm studying Bitcoin now and there's one thing that I can't find out, can you help please? When a new node finds other peers with first connection using DNS seeds, can domain server return the same IP address as the node that is trying to connect to the network? I'm asking that because it's interesting does the node filter received IP addresses to exclude its own IP or BIND returns everything excluding this node IP? If the node does it then I don't understand how it knows its own IP address beforehand because as I understand nodes know each other IP addresses only after version and verack getaddr/addr messages

to be more precise, for instance there's a blockchain with only one node, the first question is how to exclude a connection with the node itself. As I understand the node IP address needs to be excluded from received list of IP addresses returned from DNS server but the node doesn't know its own IP address (seems like that) before connecting to other peers

Because even I2P torrents are terrible slow. I tried to download bitcoin core torrent using I2P and got like 3KB/s.

do we have enough nodes in the i2p cluster? because

No. Unlike Tor, "exit nodes" - or "outproxies" as they are referred to on the I2P network - are not an inherent part of the network.

When using onlynet=onion and onlynet=i2p. The node will use both? Or use just one of them, like the last entered in the bitcoin.conf?

Which is the one to go to with a broken hard disc? Got a friend with some in mycelium wallet and broken Samsung Galaxy notepad. Needs serious lab work probably. Couldn't get to it with home equipment.

I lost access to my wallet. I need this particular application. To repeat the key generation. I guarantee a reward.

Good time of day. Tell me, I can't remember what kind of Bitcoin wallet it was. The master key/private key was generated from text using the brain wallet type. It was possible to choose the number of words for the initial phrase. As an example for a brain wallet, a text about sakura and cherry blossoms in the wind during rain was given.

but the problem is that I don't understand how to do this if the addresses are constantly changing.

DNS seeds (like seed.bitcoin.sipa.be) return a hardcoded or dynamically curated list of Bitcoin nodes. They don’t filter out the querying IP address

- Upon attempting a connection, if the destination IP matches the node’s known external IP, it avoids connecting.

- If a connection is established and the node detects that the remote peer is actually itself (e.g., via nonce check in version message), it drops the connection.

Relevant part in Bitcoin Core (net.cpp, CConnman::ConnectNode):

if (addr == self) {
LogPrint(..., "Skipping self-connection attempt to %s\n", addr.ToString());
return false;
}


And in ProcessVersionMessage:

if (remote_nonce == local_nonce) {
// Detected self-connection
pnode->fDisconnect = true;
}


A new node may not immediately know its public IP, but it uses:

UPnP or NAT-PMP to discover public IP and set port forwarding.

Echo: When it connects to other nodes, they may send addr messages containing the node’s IP as seen from their side.

Outbound socket binding: The local IP used to make outbound connections can be used as a guess.

Manual setting: via -externalip in config or CLI.

This isn't perfect, so Bitcoin Core also maintains a "local address score" system to rank and confirm its best guess.

I am also checking the I2P settings. Like if the router or the ISP is blocking something.

I think my node only uses I2P network and takes forever to sync.

Would love to get feedback from fellow BitcoinDevs / BitcoinMaxis how you would approach a Bitcoin native funding process with all logic of collecting VC but just decentralised and no shit coins involved. We basically want to accelerate Bitcoin adoption as much as humanly and technologically possible.

Hi, is anyone familiar with
• Lightning-native authentication or access models (e.g. LNURL-pay / LNURL-auth)
• Snapshot-based BTC distribution (e.g. via address map or PSBT system)
• Taproot-based commitment schemes
• Liquid-issued assets (less preferred due to trade-offs)
• Possibly even Nostr-based participation tracking
?

imo that's not solid security; you won't always achieve adequate entropy; subject to brute dictionary attack; plausibly llm's could even be used in exploit if part of your recovery phrase was known. stick with BIP39 standard when choosing seeds and choose 15+ randomly from the 2048 listed

its a futile fight, take the win by collecting their full fees and not poluting the chain less with less unspent utxos to increase security of everyone
