You may wish to look into https://qubes-os.org, it's designed to make it quite easy to isolate applications. So you can run untrusted software, and if it turns out to be a virus, oh well, the rest of your system is completely safe.

I think Ledger will not be supporting anything but BCH and BTG because BTG was already almost a scam and everything since then is even worse somehow. You don't necessarily need to keep your coins on an exchange though; you could just, after each fork, move all BTC to a new seed, then import the old seed into a program which lets you extract the private keys, then import those private keys into the full node software for the forked coin. However, this is really a pain, and I think all forks from here on out are going to be nearly worthless anyways.

This is weird, I have successfully abandoned transactions before. Maybe try -zapwallettxs as a final attempt? I think deleting mempool.dat and zapping transactions is what I did.

Is there a fork or another program that can do work on more than one pubkey at the same time?

No, it is a technological limitation. Look at my post in this thread a few messages ago about a possible scheme for mining on multiple public keys (originally invented by ArcCsch). However, this would not be simple, it would require new pool software as well and is a pretty invasive change.

Is there a method of writing the -f document in vanitygen that will allow multiple split pair jobs at once?

The -P flag is where you place the pubkey for someone looking for a job done securely for them.

Code:
vanitygen -P 04ED64430556D8A00175291C1DE84D4989D5568AFA0DEB7F9331766AF077B01470E4A44C5D7347E64AA709E8A475D4AE7658E5C9DD96CF3C8061D430BBDE1C45D7 1machine

The -f flag allows a file with one job per line, but from what I can find it only allows direct searches, not split pair searches.

work.txt

You can only mine with one public key at a time, so this doesn't make much sense. You can mine multiple addresses that all use the same public key, but not multiple addresses each with different pubkeys.

Re: Merge mining vanity addresses?
by
markasoftware
on 26/11/2017, 05:04:37 UTC
Woah, I swear I just thought of this same thing today! I think it is secure.

For the issue you mentioned, a possible solution: Require the private keys to be revealed and replaced at random intervals even if an address is not found. That way, it is impossible for somebody to maliciously withhold addresses, because they don't know if this time is "real" or not -- it may be the pool randomly asking to renew the private keys, or it may be that an address was found. An additional measure that could be taken is requiring people to put in payment before their address is mined, and if they withhold then you stop mining their address without refund, so they are incentivized to reveal their keys.

One big problem I see is how do you make it easy to handle private key revealing/generation? Most people don't have a personal server at home they can use. So, you can send an email whenever an action needs to be taken, then they can run the application to reveal and regen keys. But this requires them to frequently do it, which is a pain, and also means that whenever they don't do it their mining stops.

A partial solution is to generate many keypairs at once, and host many public keys on the pool servers. So, when an address is found, next round can begin immediately. Then, you only have to run the special application to give out the private keys once every few days. It just means that, if your address was generated, that you don't get access immediately. I think this is acceptable. EDIT: You could actually just use a deterministic HD wallet and give the xpub to the server to let it generate an arbitrary number of public keys.

Overall, it's a great idea, with tons of potential. When I'm done with my current project, I may begin work on a pool server and client application that creates and reveals keys. I think it can be backwards-compatible with oclvanityminer because all the miners actually need to do is mine againts an ECDSA public key, which is already what they do. If you are interested in building part of it, that would be great!

Re: Vanity Pool - vanity address generator pool

I've been thinking about this for a bit, and mainly about the possibility of merge-mining many addresses at once, to massively increase efficiency. This is what I've come up with:

1. Everybody who wants an address generates an ECDSA keypair, a Personal Pair
2. Everybody gives their public keys to the pool, which combines them into the Combined Public Key
3. The pool distributes the Combined Public Key to miners. The miners generate random keypairs until they find the right address when combined with the Combined Public Key, the same way it's done with split mining.
4. The randomly generated private key is given to the person who requested the address
5. Everybody but the person who requested the address gives their private key to the person who requested it.
6. The person who requested the key can spend funds by combining the pool's random private key, everybody else's private key, and his own private key.
7. Everybody else generates new keypairs and mining starts again, return to step 1

There are issues (for example, what if somebody chooses not to give up their private key after someone else's address is found?), but perhaps it is possible to work around them. This could make a big difference for mining speed, and I'm sure it is worth the downsides.

EDIT: I'm not the first to come up with this, apparently. See https://bitcointalk.org/index.php?topic=1715787.0 by user ArcCsch. When I am done with my current project, I may begin work on a merged-mining pool, and looking into cool aspects of this, for example the most optimised way to split up into smaller merged pools to minimize risk while still keeping profits higher than with "solo" mining.

There's a nice G-type star (number 4) that might eventually have some habitable planets, and a relatively rare giant K-type star, and a white dwarf. There's all sorts of gameplay possibilities there; even something as simple as a Noctis clone, where you fly around refueling at white dwarfs, would be pretty fun.

Reading console dumps is not a particularly slick way to explore the universe, so I'm planning to develop a nice front end to let people explore the generated world in a web3-enabled browser, to hopefully be completed before the crowdsale is over. Is that the sort of prototype you're looking for?

Cool, didn't see that. Looking forward to seeing this coin mature. But yeah, some sort of fancy thing is gonna be needed for this to go big, i think most people don't want to buy meaningless coordinates. Also, there should be some super-rare types of things.

Close the wallet, then relaunch it with the -rescan command line option, it will scan all blocks for transactions to resolve these kinds of issues.

Hello. The wallet doesn't seem to sync completely at this moment; after downloading 100% of the available blocks it reads: 'Catching up.. downloaded 2220 blocks of transaction history. Last received block was generated 13 hour(s) ago.'

And if you check the log, it downloads the first blocks normally and after that last block it just reads 'connection timeout' on ips with 'lastseen' multiple hours ago. As if the whole chain isn't available at this time?

Maybe someone could have a  look at this? Thanks!  Wink

My guess is that nobody is mining the coin anymore so no new blocks are being generated, and the wallet thinks it is behind because latest block is so old.
