📝 Original message:The wallet words system isn't perfect for sure but it does help the user in two main ways:
1) Assuming wallet devs ensure forward compatibility for _their_ wallet the user knows they can recover their bitcoins using the same wallet software in case of a Bad Thing Happening.
2) To an imperfect degree, they can transfer/ recover their bitcoins that are stored in Wallet X into Wallet Y. We need to give them guidance on how to do this.
I think it is up to each wallet team to explain to their users clearly how they can do this in their help. It's only good manners to show your guests where the fire exits are.
It can be a simple help page saying:
"If you want to transfer your bitcoin out of MultiBit HD to Lighthouse, do this, this and this.
If you want to use the Trezor wallet you created in MultiBit HD on myTrezor.com, do this, this and this."
That way users have clear instructions on how to recover their bitcoins.
Users don't care about BIP this or BIP that but they REALLY DO CARE about keeping their bitcoins.

📝 Original message:Good to hear the bip32 wallet structure is _so_ close to being standardised.
For MultiBit HD, we have put in support for 12/18/24 words but have the UI 'suggest' to use 12.
You can see this on the wallet creation wizard Gary recently blogged about:
https://multibit.org/blog/2014/03/26/multibit-hd-welcome-wizard.html
There's a little combo for the seed length, with 12 as the default.
@Thomas. You mention gaps. We are creating new addresses on the UI in a panel marked 'Request' where the user also types in a QR code label and a note to themselves. This gets stored away as a first class 'PaymentRequest'. The UI 'suggests' that each address is used once. There will be some gaps (where the payment request is never paid) but we aren't bulk creating addresses. I am hoping this shouldn't cause Electrum a problem.
We are also storing a timestamp (the number of days since the genesis block) to help wallet restore but that is SPV specific.

📝 Original message:Yes I saw that on reddit too.
I think it applies mainly to custom transactions rather
than where fees are calculated automatically.
Another variant of not understanding change that loses
people's bitcoins I have encountered is:
1) Import a private key of a brainwallet/ paper wallet.
2) Send a small amount of bitcoin from that key.
3) The user then secure deletes all copies of the wallet
'for security'. If they are not careful they can delete
a change address with funds on it.
In MultiBit I have tried to reduce this possibility by:
1) Hiding the ability to delete wallet (in the next version
I am removing it entirely)
2) There is always a single key in a new wallet. When
a user imports a key then that makes two. I always send
the change to the second address, if it is available.
(This is bad for privacy but at least lessens the chances
that the funds become lost).
If users are determined to use a brain wallet and
secure delete every copy of the wallet after they use
them you cannot stop them (it is their machine after all)
But these two options help lessen the chance of bitcoin
loss if they do.
For the HD version of MultiBit we are removing the import
of individual private keys entirely and only supporting HD
addresses, primarily for safety reasons.

📝 Original message:I missed Greg's point on confirmations.
It is definitely a challenge to explain/ visualize both:
+ has the transaction propagated the network ?
and
+ it it confirmed/ buried in a block ?
when those words probably don't mean much to
the intended audience.
The transaction status icons I *think* do it
(explained here:
https://multibit.org/en/help/v0.5/help_transactions.html).
It basically boils down to:
1) triangle or square : bad.
2) filling circle : good
3) tick mark : great.

Arguments against multibit default:
* Less testing, field experience on desktop
Yes this is true - downloads of multibit have typically been around
1/7th to 1/5th of bitcoin-QT downloads. It helps of course that
the bitcoinj networking/ object model is also used by Andreas
as you note.
Greg:
I think Mike has squashed the deadlocking problems with reentrant
locks (primarily in the Wallet). I haven't seen one in at least a month.
We discussed proxy support on the bitcoinj mailing list a while ago
and at the time the stumbling block was the Java library used for
the networking (Netty) did not support it. Mike or Miron would
know better than I if this is still the case.
Change address behaviour will improve significantly when HD
wallet support goes into multibit/ bitcoinj (I am hoping to get my
bit done over the summer). Matija Mazi has been working on a
Java impl of HD wallets so it is coming down the pipe but
there is a lot to do yet.
Connections out from MultiBit are:
+ 4 bitcoind nodes on port 8333
+ multibit.org (188.138.113.201) for help, current version info
(and probably more in future)
+ the currency ticker will make HTTP gets to the source of
whichever exchange(s) you have set up e.g MtGox, CampBX.
This calls should disappear if you switch the currency conversion
and ticker off.
I think that is all the connections out I make.
Mainly due to the exchanges abruptly changing their APIs and
breaking things we are planning to put in intermediate
"Exchange Data Provider" servers. Tim Molter is working on this
in his XChange project. That will enable us to patch the server
when things change and the multibits in the field won't be
affected. There will probably be a couple of these initially
for redundancy.
Alex: Yes I think most users migrate to blockchain.info or,
more recently coinbase.com. They are both good wallets
but I'd like to keep Bitcoin as P2P as possible.
Luke-Jr
I think you are right here on the number of full nodes versus
SPV nodes.
I don't think we even know yet what are the working ratios of
full nodes to SPV nodes. I haven't seen anybody do any
analysis on this.
I doubt multibit will ever participate in the Bitcoin network
other than as an SPV client. All the optimisation is to reduce
data traffic - it is effectively a mobile wallet that happens to
live on a desktop. It is not really intended to be more than
"a wallet for regular people to store and spend their bitcoin".
In English the nomenclature for direction of the transactions
is: "Sent to" and "Received with". To be honest I
haven't transliterated the localisation files to check other
language packs but the localisers are pretty good in my
experience.

📝 Original message:Hello Everybody,
Over the last few months we have been steadily adding
functionality to MultiBit including:
+ encrypted wallets
+ sign and verify message
+ stability improvements and bug fixes.
As a result of these efforts I think MultiBit is now
suitable for the entry level Bitcoin user. I propose
that we put MultiBit as the default desktop client
on the bitcoin.org "Choose your wallet" page.
I think a typical new user comes to bitcoin.org from a
google search or a Bitcoin news article. We want them to
peruse the bitcoin.org site and try out a wallet. They
should be able to get MultiBit up and running in a tea break.
Then perhaps they get a colleague to send them some bitcoin
from an Android phone by zapping a QR code.
We say: "Welcome to the Bitcoin economy !"
There is plenty MultiBit cannot do of course. However if
in the first ten minutes we get the new user interested
there is a good chance they will go on to explore other
Bitcoin wallets and solutions.
Let me know if you think this is a good idea (or not!)
and if you have any questions.
