Was trying to send btc to my electrum wallet. On my electrum wallet, I generated the receiving address by clicking Bitcoin Request button, copied to clipboard and pasted on LocalBitcoins' "Receiving bitcoin address" field. But I kept getting an error message "Invalid Bitcoin Address". What am I doing wrong? Please be nice, I'm a total noob. Thank you.
On 15 August 2010 over 184 billion bitcoins were generated in a transaction, and sent to two addresses on the network. Within hours, the transaction was spotted and erased from the transaction log after the bug was fixed and the network forked to an updated version of the bitcoin protocol.
Stop DDOS using dynamic version lists without ips. Separation of node ip and node version.
The upside from reporting a node's version is that we all know the approx % of the network nodes for each version. This only applies to non-mining nodes as we can tell by block versions what the miners are voting. The current method for non-miners is for nodes to share peer lists with ips and each node reports its version. But for sharing its version info in this way the nodes become vulnerable to DDOS filtered by version. According to the current ddoser botneko-chan there is no way to avoid DDOS by version if a node reports their version (https://np.reddit.com/btc/comments/487lxl/what_if_classic_nodes_fix_their_client_name_to/d0hk051). So the only option is to stop doing it. Separation of node ip and node version. Perhaps we can figure out the version of non-miner nodes another way. Currently a node cannot prove that it is genuine anyway. It may appear like a certain node just to fake a vote but in reality it doesn't allocate meaningful resources to the network. So ultimately node versions are rough data easily spoofed. Therefore, why risk DDOS just to get some rough data? The same rough data can be gathered another way without nodes sticking their heads out and appearing different to Core: dynamic version indexes without ips... What if all clients are upgraded to report the same version so that they appear identical and behave like Core. But they maintain a new version index with bitcoin address, version, datetime through different channels which hide the node's ip. To do this, first using vpn they try to get an existing version index eg from agreed irc channels. Then they append their own bitcoin address, version, datetime to this index. They occasionally check the irc channels and redownload newer indexes and rebuild it locally. Occasionally they send their current version index to the irc channel for others to download. Over time entries on the version index expire automatically and nodes need to re-append themselves to the index with new datetime. The version indexes could be distributed p2p but then Core nodes would need to behave the same way by default. Since Core may support DDOS by version sharing the version index via vpn to irc or some other way that hides the ip may be the only way. To verify the data is real the node owners could declare which bitcoin address on the index is their node and establish a chain of trust between each other. In this way the community can figure out the approx distribution of versions without being vulnerable to DDOS by version. Of course its not gonna be perfect data but even the existing method can be spoofed easily, so why not do it this way instead?
Bitcoin Core Wallet (Version .0.15.0.1) To Ledger Nano S. Should I Use “Legacy” or “Segwit” Address Type?
I currently have Bitcoin on the Bitcoin Core wallet Version 0.15.0.1. I am looking to send that Bitcoin to my Ledger Nano S. However, when I open the Ledger Wallet Bitcoin app in Chrome and unlock my ledger, I obviously select “Bitcoin”, but the next screen asks for the address type…either “Legacy” or “Segwit”. I am looking for someone to confirm what address type I need to select, or if it even matters. If it does matter, can someone explain why I would send to one and not the other and/or visa-versa? Once this Bitcoin has been transferred, I have a very small amount of Bitcoin on an exchange and I would like to send that to my Ledger Nano S as well. Do I have to be concerned which address type to send to from the exchange? Thanks for your help in advance.
Recovering private key of change address from Bitcoin Core
Hello, I am trying to help my mostly Bitcoin-ignorant friend with the following problem: A long time ago, he mined some BTC using Bitcoin Core client with unecrypted wallet.dat. Some years later, he added encryption to his client and sent some BTC to someone else ("transaction X"). Then he forgot the password of his wallet.dat. He had backed up the original (unencrypted) wallet.dat file so I managed to extract private key of his mining address from it and send his funds safely elsewhere. However, during "transaction X", around 0.7 BTC ended on a new "change address". I cannot access the private key of this "change address" because it was generated after the wallet was encrypted and he forgot the password. Or is there a way to find this private key, e.g. are the change addresses PKs in Bitcoin Core generated using some non-random derivation algorithm? I have access to both versions of the wallet.dat file (original unecrypted and later encrypted before "Transaction X") EDIT: Thanks everyone. The wallet was old (non HD) type so the change address' private key is probably lost forever, unless my friend remembers his password.
