Wellcome to all ! I need Old Testnet Chains for my own research, so i`d like to know if they are available for download somewhere. Or are they lost?  Apparently, there were 2 former testnets prior to the current testnet. Information on the wiki: https://en.bitcoin.it/wiki/TestnetThere have been three generations of testnet. Testnet2 was just the first testnet reset with a different genesis block, because people were starting to trade testnet coins for real money. Testnet3 is the current test network. It was introduced with the 0.7 release, introduced a third genesis block, a new rule to avoid the "difficulty was too high, is now too low, and transactions take too long to verify" problem, and contains blocks with edge-case transactions designed to test implementation compatibility. On the December 21 of 2015 SegNet was deployed, to test the Wuille's Segregated Witness proposal. Im not sure if someone saved them for historical purposes... I guess someone still has them and could post them there. Trying to download them with the old clients wouldn't work because I doubt there are any peers anymore but you could try. |

You can always download the old wallet and export the private key then in the new wallet import the private key.
The most common advice i've seen to start using the HD format is to empty is to send your own bitcoins into a new empty wallet, so you would need to create an empty wallet, create receiving addresses (as many as needed for privacy reasons) and then send the BTC there. Newly created wallets are HD by default since 0.13 I think. Sweeping private keys is not recommended because it could be fatal if your computer was compromised and attacker saw them. The good news is, apparently (according to achow here) version 0.16 will automatically convert your wallet into an HD wallet so you don't need to waste fees doing this. |

I did some more research on this... turns out Bitcoin Core has been capable of showing watch-only addresses on the GUI for a while now (I think around 2014 was when it was introduced). It looks like this:  Pretty nice to see GUI support. Now I just I need to learn how to sign transactions offline properly. If anyone knows how to do this I would like to hear. I guess there's no other way but to do it with raw transaction data but im not sure how to go about it. |

Fees must be paid in Bitcoin... it is part of how the system works. You would most likely need a hardfork for such a change. Maybe with lightning network channels you can route them somehow to fiat but I don't see the point, as it was mentioned, the fees are what they are because the resources (blockchain space) is limited. It's like if there was an auction every 10 minutes to get inside the blockchain, and highest fees get a priority. This doesn't change no matter where you link the fees with.

Just realized how this is a sticky post by Gavin Andressen itself. It's pretty funny in retrospect to see Gavin Andressen supporting alternative blockchains, since he has been pro Bitcoin XT, pro Bitcoin Classic, pro Bitcoin Unlimited, pro Bitcoin Cash... and the list goes on, which are all, or attempts of, alternative blockchains, when a couple of years ago he was advising against them.
Several other developers are now even making their ICOs (Jeff Garzik et al).
This is good to archive for historical purposes.

Hi, I have a Ledger NanoS, I sent some BCC to my BTC address on my wallet, from the Binance trading platform, but it never arrived. I have traced it to the Bulldozer Blockchain, does anyone know how I can retrieve these coins?
I have no idea what you are talking about with "Bulldozer blockchain". Why did you send BCC to a BTC address? It's two separate blockchains, you are supposed to send BCC into BCC address and BTC in BTC addresses, even if the idiots over BCash decided to give the exact same address format as seen in BTC to confuse newbies. Im not sure if you could sweep the private key of that BTC address where you send the BCC to, and put it into a BCC wallet and re-scan it to search for these on the BCC blockchain. |

i'll invest in masternodes
what coins you suggest to buy to invest in MN?
i am looking for something easy to built, with a dedicated hosting service with full automated support
I would have invested in masternodes back in the day if I knew Dash (formerly known as DarkCoin) would have turned out to be such a big and lucrative project. This wouldn't change the fact that I still personally think the developer was a scammer that instamined the coin, but well, you can't deny how it has grown and people that got early on on the masternode game are making profits from doing nothing I can't think of a single decent project with maternodes on.. I guess you can look at PIVX, or that Poswallet one where they intend to decentralize PoS for newbies to stake online. If they can get that done I guess it will be an interesting project to be at. It's yet to be seen how their math works on that one. |

I never used Trezor or anything that creates a wallet throught a seed. Does it have something called "Coin Control"?
You can simply use your Trezor (or Nano S) with Electrum if you need coin control... One of the main reasons Bitcoin Core is the best wallet out there is that it has maximun control over inputs and outputs. So If you recieved for example 20 transactions of 0.05 each for a total of 1 BTC, and each of these were received in 20 different addresses, and you wanted to send that 1 BTC at once, like you said, someone could see that you own all of these 20 addresses. This is of course bad for privacy, so with Coin Control feature you could select the inputs and send them separately. Of course, this sucks because you must send 20 times 0.05, paying a fee each time, but there's nothing else you could do that I know of. This is the known problem of Bitcoin's lack of fungibility, which hopefully gets fixed somehow some day.
Your idea of sending 20 different transactions is arguably only slightly better privacy-wise than sending 1 transaction... UNLESS you send each of those 20 transactions to a different address. Otherwise, you are effectively linking all 20 transactions anyway by sending to 1 address. Granted, it makes it more difficult to prove that all 20 are actually controlled by one person (ie. You) but the link is still there. Another option is to send your 20 transactions to a mixer and then combine them all into one outgoing transaction from there.... Or use Monero   Yes, I obviously mean that you should use the 20 different transactions into 20 different addresses, which is why im looking for an exchange that will let you generate new deposit addresses each time, because for example in poloniex I have had the same deposit address for ages which sucks, and I don't know how to generate one, and im not looking forward to create 20 different accounts with 20 different emails and usernames. I don't know how you would use Trezor with Electrum, but to answer the other guy, you can use Bitcoin Core as your node with watch-only addresses, and then use Armory in an offline computer to make the transactions. Im still researching how to do this, and I would like to use Bitcoin Core as cold storage wallet too better than Armory because im paranoid to use anything that isn't Bitcoin Core to be honest. I want to stay with the classic wallet.dat format. I don't trust the idea of "seeds" at all. Two reasons I no more using core: 1) It was not deterministic and i was bored making backups continuously ... I know now it is but I'm kinda get used to HW wallet and not going to return back to core 2) blockchain size EDIT: after reviewing my point 1 ... do you realize core is using the same BIP as Trezor (BIP32)? And HCP is right, Leger together with electrum is pretty powerful tool. Im still using the non HD format from the old wallet. In any case, I can't trust hardware that was designed to host bitcoin private keys. Trezor has been caught "phoning home" before: https://www.reddit.com/r/TREZOR/comments/6yti7p/trezor_bridge_trezordexe_calling_home/Why would I need any device when I can get an airgapped computer with libreboot on it to deal with private keys? Hmm, this is interesting. I was not aware of this ( I'm ledger user ). Thanks for link. Going to read it. on a side note I do not consider using outdated software safe. But it's your choice. What do you mean outdated software? There's nothing wrong with the old wallet.dat format, you just need to keep making backups as you said. I did read achow101 saying that the new HD format has no negative points. I guess I will just wait, apparently 0.16 will allow you to use HD in an old wallet, im not sure how, I think it will use the HD method for newly generated addresses while keeping the old keys the same, this way you don't need to move your coins to an emtpy wallet to use HD which is annoying and one of the reason im using the old format, I was not looking forward to lose money in fees doing this. Im using the latest Bitcoin Core, you can use the old wallet.dat from years ago in new versions in case you meant that I was using an old Bitcoin Core version. |

Wow, that's pretty long talk about nothing. I would say you lack the basic principles how this works.
Seems to me you are pretty paranoic but OK. I just say don't worry.
There is nothing wrong about using address repeatedly (only privacy issues .... if you publish 1st address and then send tx together with funds from other address anybody can assume you are the owner of both addresses ... but that's all).
If anybody founds a way how to break/bruteforce the BIP-0032 (trezor seed generation) I guess a major part (maybe 20-30%) of all existing BTCs going to be compromised and will be dumped asap. Completely ruining the BTC price and making your issue minor.
but If I send a large BTC transaction then everyone can see ALL my public adresses right? so my SEED has 1btc, these are on 20 public adresses, I send 1btc to someone, BOOM now anyone can see on blockchain and know the 20 inputs all belong to one person. because the inputs are my public adresses. Edit---> What I'm saying it doesn't matter even if not reusing adresses, bcs the inputs are all connected to same seed do you have proof that 20-30% of all bitcoins are in Trezor devices, sounds high to me. I never used Trezor or anything that creates a wallet throught a seed. Does it have something called "Coin Control"?

Sounds like a pretty convoluted presentation to me. A lot of "TBD" (to be debated) stuff. Also they don't claim at any moment that people will be able to verify their own transactions. At the end when they take only 2 questions, one of the questions is how is he going to be supposed to keep running a node, and Peter Rizun tells him to use an SPV wallet, then the guy in the audience asks "how secure is that", and *crickets* happen, then Andrew Stone tells him to buy a new computer basically, but I still don't see how even with the most powerful computer in the market this is doable, and also they don't address orphan blocks issue and so on as far as I can tell.
In any case you already know what Craig Wright thinks about people running full nodes. It is simply not part of their model. They claim that as the Bitcoin economy growths, so will nodes, even if less and less people can afford running their own. The question is how decentralized is that.

Hi guys, I'm currently Jr and i ranked up from newbie status in just the time as everybody says (with 14 activity every 7days), big thanks for that😊
But now i can't figure out or can't find any info on next rank up, not that i'm complaining. If anyone can just enlighten mo on the rules in this phase coz it's been 3 weeks and my activity seems stuck at 42 even with posts of 70+
Just asking, if anyone is kind enough to answer please, would be grateful
Brand New: 0 posts, gets 1 gold coin under his name.
Newbie: (none), gets 1 gold coin under his name.
Jr. Member: Activity: 30, gets 1 gold coin under his name.
Member: Activity: 60, gets 2 gold coins under his name.
Full Member: Activity: 120, gets 3 gold coins under his name.
Sr. Member: Activity: 240, gets 4 gold coins under his name.
Hero Member: Activity: 480, gets 5 gold coins under his name.
Legendary: Activity: the Legendary membergroup has no universal activity requirement.
You are guaranteed to become Legendary somewhere between 775 and 1030 activity,
but the exact point in this range at which you become Legendary is random per user.
Gets 5 gold coins under his name of which the last is half dark blue. This thread has all the info you need: https://bitcointalk.org/index.php?topic=178608.0It is better to not pay attention to that. I just post regularly and I don't even know when I turned Legendary. I just noticed you have 56 points of activity already, not 42, so you should be Member around 5th December which is when the next 14 day period begins. Notice that you can't increase more than 14 points every 14 day period no matter how many times you post. |

How much does it cost to fork bitcoin?  The cost to fork Bitcoin is free. One merely needs to make an incompatible change to the software that will fork the network. The cost of a Bitcoin fork (like Bgold) is externalized onto the ecosystem. Newbies get scammed by downloading malware wallets or naively inputting their private keys into nefarious web wallets. Exchanges and wallet services need to spend endless hours building new wallet infrastructures to safely handle coins on both chains. This is particularly true if the fork has no replay protection. And if there is no replay protection, there are potentially huge losses for users, both because of individual mistakes (not splitting coins) and custodial mistakes (exchanges/wallet services fucking up and losing coins). So, it's free for the fork devs. And there might be "free money" in it for those who can properly secure their money and split their coins. But there are certainly costs involved..... The devs that decide to pre-mine the fork (like Bitcoin Gold) definitely get a nice premium. Some devs can also know what exchanges are going to list their fork before the big public, which means they move their BTC to these exchanges to have instant liquidity to dump the fork for BTC if want to, and in general manipulate the price. A lot of price manipulation is going on on all forks, BCash mostly, and now Bitcoin Diamond too. It can be considered free money tho... as a BTC user, you don't really lose anything, other than time securing you access the coins properly and the fees, but if you do it at the right time, you can find profit on that. The only scenario where it is not free at fundamental levels is when the fork uses SHA256, because the fork competes against BTC for the hashrate (which is why BCash is an attack on Bitcoin). |

How come there is no cryptocurrency pegged to the value of Bitcoin but with superior transferability?
Compare with the gold standard. Most people would never actually cash in their banknotes to get gold, because gold is awkward and unpractical to use in daily life (kind of like bitcoin). The fact that you are guaranteed the notes value in gold makes a bank note much more practical and almost as reliable.
There are tons of cryptoes out there, but most of them are (to me) worthless since they are not following the value of bitcoin or any other storage of value. At the same time Bitcoin is far too slow to make daily life transactions. Can't a contract be made to guarantee an 1-x conversion rate, or what?
Couldn't a more cost efficient technology bridge them, like a currency using DAG (or whatever) for a daily-use currency? Very few people store their bitcoin on an exchange because it's not as secure, but I still bet most of us bought or sold bitcoins and therefore at some point stored them on an exchange for a short amount of time.
Why are no other currencies using bitcoin as a store of value?
Because it's still not possible, but with Lightning Network, Litecoin (for example, but this would be most ideal as it's got a long story and the tech needed + it's a simple coin) could work as fiat backed by BTC with atomic cross chain transactions. But with LN and segwit, Bitcoin itself can be issued as "fiat backed BTC". I would have liked for BTC to stay purely as digital gold and a coin like Litecoin to take this role tho. We'll have to wait and see how things develop in 2018-2019 for this. |

Can anyone explain the latest events on this and why this is even controversial?
Bitcoin Knots complies with current consensus rules, so do other clients like Libbitcoin or whatever that was called (the by Amir Taaki I think). I don't see a problem with these being hosted there but it should be clear that they are secondary to Bitcoin Core, just list Bitcoin Core first, then list the alternative clients, and aware people that for example Knots contains experimental stuff. As long as they follow current consensus rules (1MB blocks etc) I don't see where the problem is. A node is a node and it strengthens the network (again, as long as it's a Bitcoin node and not some fork).

Hi guys, I have recently invested into phore its a new coin with superb features, master nodes etc and there is a pre burn coming up in less than 7 days of nearly 50% to around 8 million , below is the link to the official thread ! I think this could be a hidden gem, just been listed on cryptopia. Let me know your thoughts! https://bitcointalk.org/index.php?topic=2307909Looks like your average Proof of Stake coin, with Masternodes (already done before a million times) and with the Zerocoin protocol (some existing coins are already using the Zerocoin protocol), so I don't see why this coin has "superb features". Even if it implements segwit and so on, it doesn't really matter, most coins are implementing segwit nowadays the pump effect is not there anymore. What is PoS 3.0 anyway? |

The EDA was finally hit and nothing happened. The price of BTC is so stable during the past hours around $8100 to $8300, and BCH is down %10... once again, all the idiots that thought there would be a flippening lost their BTC in a shitcoin. Hopefully they start learning the lesson soon, because it's sad to see big players manipulating noobs into this.

I don't day trade so I don't keep a daily percentage of gains. I make very few, calculated trades, like for example, Bitcoin->BCash trades depending on how much manipulation Jihan Wu and Roger Ver are creating with the fork.
Other fundamentals may influence trades I want to do, but I don't trade no more than 5 times a month or less so I don't bother with a daily estimation, I only measure gains monthly if I even measure them since im not a trader.
