All of these transactions use scripts. These scripts can be encoded as a script hash and used in a Pay-to-script-hash (P2SH) output which corresponds to a Bitcoin address beginning with a '3'. Multisignature addresses have scripts of the format OP_0 <pubkey 1> ... <pubkey n> OP_n OP_CHECKMULTISIG where n is less than 15. The OP_n indicates how many of the previous public keys are required in order to spend from that address. Escrow transactions are basically smart contracts. Bitcoin doesn't really support this well yet. These smart contracts are really just complex scripts. Timed transactions are transactions that use the nLocktime field of the transaction. This field prevents the transaction from being confirmed until a certain time. They can also be used in scripts for P2SH addresses which use OP_CHECKLOCKTIMEVERIFY which will ensure that Bitcoin cannot be spent from that address until the nLocktime has passed. Ok but is there any way that the end user (so someone with no bitcoin expertise) can use these in any wallet? Or is this something only for the very gifted bitcoiner that's been here for years and knows what they're doing? Honestly I barely understood a word you said there and was just wondering if I was actually able to go about using these in a simple way. - An end user can't do time locked transactions (CLTV) at the moment because no wallet provides a user friendly interface for that. - Lots of wallet support multisig addresses. Copay and electrum are examples. - As far as escrow transactions are concerned an end user can't do smart contracts yet because no wallet provides an interface for that. However you can do escrow transactions of another sort via bit2factor.com: https://bit2factor.com/bitscrow/ |

try updating to 2.7.11 which is the latest version. whatever bug you are encountering may have been fixed already.
Thanks but not only it didn't help and the issue happened again - i had to removed all files and restore 2.6.4 wallet from scratch since it somehow could not restart anymore after the wallet was loaded in 2.7.11. I'm totally lost about this problem, all versions worked like a charm until 2.7.X you say that you restored from scratch then I'm assuming you have the seed written down? In that case upgrade to 2.7.11 again and this time restore your wallet from seed using 2.7.11. hopefully that'll fix the problem. you should know that the wallet file format changed in 2.7.x so that's why you can't use a 2.7.x wallet file in previous versions. you can still restore from seed in all versions though. if restoring from seed in 2.7.11 still doesn't fix your problem than I suggest creating an issue on github: https://github.com/spesmilo/electrum |

bitcoin clients aren't mutually compatible so give up on the idea of using different clients on your PC and phone and trying to get them to share the same wallet. i'm not saying it can't be done. it's just not something a newbie should be trying. if you want a single wallet that will work on multiple types of devices then i suggest copay. |

According to this post from 2013 It seems like Electrum had Command lines available for Windows but got disabled after sometime so It's only available for Mac & Linux right now. Just to make sure , I tried too and It didn't work either. that is an old thread so i don't think its relevant today. try "electrum.exe help" just in case that does it. I tried that (my wallet has the version in the name) and It didn't work , I also tried to launch it from the path like this C:\Users\admin\Desktop\electrum-2.5.4.exe help and It didn't work either , have you tried it your self at least? No I haven't tried it since I don't use Windows myself. Sorry if I led you on a wild goose chase. That was not my intention. I just found it difficult to believe that there would be a CLI on linux and mac versions and not on the far more widely used Windows version. BTW wouldn't the electrum .exe file be somewhere in program files? that is where programs are installed in Windows right? Also 2.5.4 is very old. You should install the latest 2.7.11 version. It's not in program files because I took the Standalone version and not the Windows installer , so I only have the executable (of 25 MB) on my Desktop and the other files (generated by the executable) on the AppData folder and yes the program files is where the programs should be. I didn't upgrade because I was afraid I screw things up as I'm not sure how to upgrade without using the seed (If that's even possible) first write the seed down just in case. then download the latest windows installer version from electrum.org and run it. the new version will pick up your wallet just fine and you won't need to restore anything from seed. then try `electrum.exe help`. |

Thanks for the responses.
I'll take the advice and avoid 2FA for now. I'll look into Trezor and other cold storage methods.
At the moment, I'm not able to send bitcoins with Electrum, but there's bitcoins sitting in it. Am I to understand that creating a new standard wallet will resolve the sending issue? Just export keys from current wallet, and import to new one? I don't remember doing anything the first time around to create a Watch-only wallet. Is there a specific step I should pay attention to avoid this issue on a new wallet?
Thanks again.
watch-only wallets don't have private keys. but it could be you have a multisig wallet like btchris said. What does the address on the receive tab look like? Does it begin with the number 3 or the number 1? |

electrum doesn't take a cut btw. transaction fees go to miners in the bitcoin network.

Transaction ID d7d21f4271b74705101edb4cc7db14
7ed5d2038ddc39cde947f75be32bb4e36f
that tx is unconfirmed. there's currently a huge backlog of unconfirmed transactions: https://tradeblock.com/bitcoin/everyone is affected not just electrum users. there is nothing you can do but wait it out. No. It is not because there is a "backlog" but rather because his transaction fee is much too small. He is paying only ~10 satoshis/byte. According to http://bitcoinfees.21.co/, the current recommended fee to get the transaction into the next block is 100 satoshis/byte. yeah i didn't notice that. that is way too low. still the solution is the same. he has to wait it out. in the meantime maybe we can help him learn how to set more reasonable fees? what version of electrum are you using @revenga? |

run `electrum help` to see the command line options.

seems like they haven't fully tested their software. let them know that electrum and mycelium are among the top bitcoin wallets and if they don't support them they will lose out on customers.

I already picked Privacy from there. The problem is I don't see "Send from" button in anywhere.
Oh now I see the problem. It shows Freeze but doesn't show Send From in empty addresses. When I click a address with BTC in it it showed me Send From button. I didn't see in Receive tab but Addresses tab. Thank you all for your help.
Yeah I guess I should update that blog post. One other point is that by default the addresses tab is hidden so to make it appear you have to press ctrl + A. |

That did the job! Thank you so much!
Glad I could help! |

But i never used that address once. I used this other one at least 50 times etc. No issue with me using the one i always use right?
don't fixate too much on addresses. think of them as disposable entry points into your wallet. you use an address once and then you never use it again. that doesn't mean that you can't use it again. it's just that it is bad for your privacy because all transactions are public. so best not to reuse addresses. |

trusted coin, the company that co-signs 2fa transactions, is having some problems so maybe this is related to that. perhaps you should contact them: https://bitcointalk.org/index.php?topic=1656040.msg16644202#msg16644202There are 2 other threads about 2fa problems in this forum currently. I don't think I've ever seen 3 threads about 2fa all at once in this forum. Something's definitely up! edit: do let them know your electrum version. They seem to think that only 2.7.9 users are affected: https://bitcointalk.org/index.php?topic=1656917.msg16644415#msg16644415Also once you get access to your bitcoins I suggest moving them to a new 2fa wallet. This time make sure you write down the seed. To create a new wallet use file > new/restore. To open it use file >open. To make a shortcut to it use the command `electrum -w /path/towallet/file`. The wallet file is stored in this directory: http://docs.electrum.org/en/latest/faq.html#where-is-my-wallet-file-locatedIf you decide to create a new wallet file then please make sure that you stop using the old wallet file. Don't delete it but do make sure that when you send bitcoins to your wallet that you do so to your new wallet and not the old one. The electrum window title will contain the name of the wallet you are using. |

Thanks for the replies, and yeah both my pc and iPhone clocks are synced to the correct time. I tried restoring the seed but was having some troubles with it just greying out. And yeah im using the right wallet file also.
How do I use my seed to request my google authenticator secret?
what version of electrum are you using? how many words are in your seed? |
