Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Groestlcoin EasyVanity 2020

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

Remastered! – Groestlcoin WPF Desktop Wallet (v2.19.0.18)

Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode.
This wallet was previously deprecated but has been brought back to life with modern standards.

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

Transcript of Open Developer Meeting In Discord - 5/10/2019

[Dev-Happy] Blondfrogs05/10/2019
Channel should be open now
Chill05/10/2019
you all rock!
just getting that out of the way :wink:
Tron05/10/2019
Cheers everyone.
theking05/10/2019
Hi fabulous dev team!
Hans_Schmidt05/10/2019
Howdy!
Tron05/10/2019
No specific agenda today.
Questions?
Has everyone seen Zelcore wallet, and Spend app?
theDopeMedic05/10/2019
Any major development status updates that haven't been listed in #news?
Synicide05/10/2019
How was the meetup yesterday? I heard it would be recorded, it is uploaded anywhere yet?
Tron05/10/2019
And Trezor support on Mango Farm assets?
@Synicide Yes it was recorded. The Bitcoin meetup organizer has the video.
I talked about Ravencoin, but mostly about the stuff that was being built on/with/for Ravencoin.
There was about 70% overlap with folks who were at the Ravencoin meetup in March.
Synicide05/10/2019
awesome, looking forward to watching it when it's available
Tron05/10/2019
I'll hit up James and see if he's posting the video.
S1LVA | GetRavencoin.org05/10/2019
@theDopeMedic I'd follow github if youre interested in development status
Synicide05/10/2019
zelcore looks super slick. Been meaning to research its security more with the username/pw being stored on device
Chill05/10/2019
How is the progress on the restricted assets and testnet coming along? A secondary question would be about the approximate fork timeframe.
S1LVA | GetRavencoin.org05/10/2019
Has anyone heard from the community dev (BW) working on Dividends?
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Any word on BW and his progress w dividends?
@S1LVA | GetRavencoin.org LOL
Tron05/10/2019
@S1LVA | GetRavencoin.org Great question. I haven't heard.
Synicide05/10/2019
last meeting BlondFrogs said he would try to connect with BW as he was sick with the flu at the time. Maybe he has an update
S1LVA | GetRavencoin.org05/10/2019
I've tried to get in contact, but with no success.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Got a funny feeling...
Jeroz05/10/2019
Last time we left off with someone mentioning a foundation and Tron saying let’s discuss that next time iirc
kryptoshi05/10/2019
Has anyone taken a look at the merits for this proposal? Thoughts? https://medium.com/systems-nexus/modified-x16r-algorithm-proposal-for-constant-hash-rate-in-short-time-164711dd9044
Medium
Modified X16R algorithm proposal for constant hash rate in short time
Interpretation Lens V. a0.01
Tron05/10/2019
I did see it. Does anyone think this is a problem?
Synicide05/10/2019
It looks interesting... but I'm not sure what it is trying to solve. Looking at netstats, our 1 hour average block time is perfectly 1 minute
S1LVA | GetRavencoin.org05/10/2019
Last I heard from him he expressed how important finishing the code was. I wouldnt jump to conclusions on his absence within the community.
Synicide05/10/2019
x16r by nature will fluctuate, but DGW seems to be doing a good job keeping consistent block times
Tron05/10/2019
Because of relatively broad distribution across the algorithms, the block times are fairly consistent. It is possible, but very, very unlikely to get a sequence that takes up to 4x longer, but that's super rare, and only 4 minutes.
We did some timing analysis of the algorithms early on. A few are 1/2 as long as SHA-256 and some are up to 4x longer. But when you randomly select 16 it usually comes out about even.
Synicide05/10/2019
1hr avg: 1.02min - 24hr avg: 1min
I think we should focus on building, and not trying to fix what isnt necessarily broken
Tron05/10/2019
Agreed.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Agreed
Tron05/10/2019
Is everyone ok with the frequency (every other week) of this discussion?
Jeroz05/10/2019
(Added thumbs down to measure)
Tron05/10/2019
@Jeroz Did you do thumbs-up and thumbs down?
S1LVA | GetRavencoin.org05/10/2019
Seems appropriate. Its not like the devs dont poke around here and chat anyways.
Tron05/10/2019
Anything critical that we should be aware of?
Jeroz05/10/2019
When I need a dev, I poke a dev. When that dev is unavailable. I poke another one :smiley:
Hans_Schmidt05/10/2019
BlondFrogs was testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends.
Jeroz05/10/2019
I hope I didn’t offend any devs
With poking around
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Was thinking voting would be an excellent use case for restricted assets. Local communities, nations, etc... could kyc their residents
radiodub05/10/2019
Is x16r will remain fpga mineable
Tron05/10/2019
@Jeroz We're hard to offend.
Chill05/10/2019
Is the general dev feeling that the next fork should and will include everything needed for the next 6-9 months (barring something completely unforeseen)?
Jeroz05/10/2019
I know :smile:
Tron05/10/2019
@radiodub Nearly impossible to stop FPGAs and still keep GPUs
Jeroz05/10/2019
About that: voting is another hard fork right? Not too soon?
Tron05/10/2019
FPGAs can be reprogrammed as fast. It is silicon (true ASIC) that we can obsolete with a tiny change.
@Jeroz Messaging, voting, Tags, Restricted Assets would require a hard fork (upgrade).
We could do them each individually, but folks get weary of upgrades, so current plan is to roll them together into one.
MrFanelli™05/10/2019
Good idea
Jeroz05/10/2019
Oh voting too?
MrFanelli™05/10/2019
People will like that
Jeroz05/10/2019
I thought that was coming later
Tron05/10/2019
Voting is the one that isn't being worked on now. Tags and Restricted assets have taken precedence.
Jeroz05/10/2019
I know. But you plan on waiting to fork until voting is also done?
That would have my preference tbh
But I can see an issue with too many things at the same time
Tron05/10/2019
If someone wants to step in, we've had one of our devs sidelined and he was working on BlockBook support so more light wallets can connect to Ravencoin. Mostly test cases needed at this point.
S1LVA | GetRavencoin.org05/10/2019
Thats a pretty large upgrade.. Bigger surface for unknowns
Rikki RATTOE Sr. SEC Impresantor05/10/2019
At what point would RVN community consider moving to ASICs because having a Bitcoin level of security would eventually be needed?
MrFanelli™05/10/2019
Never rikki
Tron05/10/2019
@S1LVA | GetRavencoin.org 100% Lots of testing on testnet and bounties.
[Dev-Happy] Blondfrogs05/10/2019
I am here :smiley:
Tron05/10/2019
@Rikki RATTOE Sr. SEC Impresantor There's nothing inherently wrong with ASICs but it tends to centralize to data centers and less opportunity for anyone to just run their gaming rig overnight and collect RVN.
Welcome Blondfrogs
MrFanelli™05/10/2019
Asics are too expensive. If we want normal people to mine, then we cant be an asic network
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Tron True but what happens when the chain needs a Bitcoin level of protection?
Tron05/10/2019
More GPUs, more FPGAs
MrFanelli™05/10/2019
Nvidia loves ravencoin :stuck_out_tongue:
Chill05/10/2019
ok, so we are pro FPGAs
𝕿𝖍𝖊 𝕯𝖔𝖓 𝕳𝖆𝖗𝖎𝖘𝖙𝖔 CEO ∞05/10/2019
Build it and they will come
Tron05/10/2019
It's all relative. It is cost to attack. If an ASIC isn't available for rent, then only option is rental of non-allocated GPUs
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Chill Eventually everyone will need FPGAs to be profitable on RVN, at that point I don't see why we just don't make the switch to ASICs
Tron05/10/2019
Also, as much as we don't focus on price, the price does matter because it determines the amount of electricity and hardware will be deployed to get the block reward. Price increase means more security, more mining means more security means higher price.
It's a circle.
Chill05/10/2019
someone tell that to the twitter handler
HailKira05/10/2019
you guys adding seedphrase to desktop wallet?
[Dev-Happy] Blondfrogs05/10/2019
@HailKira We will, just is not a high priority right now.
MrFanelli™05/10/2019
Twitter handle wants rvn ded
Rikki RATTOE Sr. SEC Impresantor05/10/2019
I just don't see much difference between ASIC and FPGA and I'd rather have the added nethash an ASIC will provide once GPUs are virtually kicked off the network
kryptoshi05/10/2019
I'm at 11 GB future proof
Tron05/10/2019
That also limits miners to big money, not gaming rigs.
Synicide05/10/2019
@Rikki RATTOE Sr. SEC Impresantor you have to keep in mind the 'added nethash' is all relative
Rikki RATTOE Sr. SEC Impresantor05/10/2019
FPGAs will limit miners to big $$$ too IMO
Tron05/10/2019
@kryptoshi New algo x16r-12G requires 12GB :frowning:
Seal <:cricat:> Clubber05/10/2019
But sperating smaller gb cards would lead to less adoption if we ever become a mainstream coin.
Adpotion of mining that is
Chill05/10/2019
but we are a mainstream coin
Seal <:cricat:> Clubber05/10/2019
Mains stream as in what eth did
Tron05/10/2019
@Rikki RATTOE Sr. SEC Impresantor I agree. Not a perfect solution.
Steelers05/10/2019
Is this a Dev meeting or Algo meeting :smiley:
Seal <:cricat:> Clubber05/10/2019
But if we ever go mem lane. We should aim for 6 or 8gb.
Tron05/10/2019
Open to other questions.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Tron Probably not the time and the place to have this discussion as we stand currently but IMO we're gonna have this conversation for real eventually
Seal <:cricat:> Clubber05/10/2019
Most cards have 6gb now.
kryptoshi05/10/2019
Why 12 gb ? Such a massive jump
Seal <:cricat:> Clubber05/10/2019
^
Would also like to know
Tron05/10/2019
@kryptoshi I was joking. You said you had 11GB card.
Seal <:cricat:> Clubber05/10/2019
Haha
You got em good
I cant imaghine the face he had when he was 1gb short
Lel
Rikki RATTOE Sr. SEC Impresantor05/10/2019
That's what she said
kryptoshi05/10/2019
Hahaha
MrFanelli™05/10/2019
need a 2080ti
Seal <:cricat:> Clubber05/10/2019
How much does the VII have?
16?
[Dev-Happy] Blondfrogs05/10/2019
Any other questions you have for us?
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs You were testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends.
Chill05/10/2019
a dev might want to contact Crypto Chico for some 'splaining
[Dev-Happy] Blondfrogs05/10/2019
I still haven't contacted the developer that was working on dividends. Was pretty busy with some other stuff. I will contact him this next week, and see where we are at for that.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Chico doesn't do interviews, shame. Tron would be a much needed interview for his community
[Dev-Happy] Blondfrogs05/10/2019
As far as releasing dividends, I can be released at anytime the code is finished and doesn't require any voting or hardfork to occur
kryptoshi05/10/2019
Android asset aware wallet?
Seal <:cricat:> Clubber05/10/2019
Is in beta right
Tron05/10/2019
Testing went well today on Android. Nearing release.
[Dev-Happy] Blondfrogs05/10/2019
as it is a mechanism that is wallet specific
liqdmetal05/10/2019
no protocol level dividends you guys are saying?
[Dev-Happy] Blondfrogs05/10/2019
correct
Tron05/10/2019
DM me if you want to test Android with Asset support. I'll send you the .APK.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
RVN gonna be on tZero wallet? :yum:
liqdmetal05/10/2019
why not? what is the logic on non-protocol dividends
assets + protocol dividends is nirvana
[Dev-Happy] Blondfrogs05/10/2019
dividends is pretty much sending payments to addresses. Right now, you would have to do this manually. The dividends code, will allow this to be done quicker and easier.
No consensus changes are required.
Tron05/10/2019
New Android wallet is BIP44 and original Android wallet is BIP32/BIP39 so the words will not find the funds. You'll need to send them to another wallet, and then send them to new BIP44 derived address.
liqdmetal05/10/2019
we already have payments to addresses
so dividends is not a feature so much as simple wallet script
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs The dividend code changes look risky'er to me than messaging. Would you consider "tags" branch test-ready?
[Dev-Happy] Blondfrogs05/10/2019
Not yet @Hans_Schmidt
Dividends is easier then you would think if coded correctly. I still haven't seen the code from the community developer. Excited to view it though.
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs Sorry- I meant restricted, not dividend
kryptoshi05/10/2019
@Tron on the Android wallet, anyone successfully added their own node and got it to sync faster? Always have issues. I have a supped up node and cannot get it to work with the Android wallet...
[Dev-Happy] Blondfrogs05/10/2019
@Hans_Schmidt Oh, that makes more sense. Yes, they are very risky! That is why we are going to create a new bug bounty program for restricted assets testing.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Once the network does get flooded w FPGAs, should we even consider changing the algo a couple times a year? That would only give bitstream developers added time to hoard their creations for themselves
Kind of like they're already doing with their x16r bitstreams :yum:
kryptoshi05/10/2019
Flooded... lol... like that hardware has mass production scale like gpus...come on dude
MrFanelli™05/10/2019
Bip44 wallet? :smiley:
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@kryptoshi Eventually yes, where there's $$$ to be made, people make things happen
MrFanelli™05/10/2019
So can we trade from that in the new Binance Dex when RVN get listed?
kryptoshi05/10/2019
@Rikki RATTOE Sr. SEC Impresantor Yes Soon TM lol. :soontm:
Tron05/10/2019
@kryptoshi There are some things we can do to speed it up. For a new wallet, it shouldn't need to sync. For recovered wallet, it needs to sync from beginning of BIP44 wallet support on iOS so words can be moved between the two.
Other options include grabbing the first derived address and looking it up on an explorer to see when it was first used and sync from there.
Another option is to add an optional number with the 12 words so it knows when to start syncing.
There isn't a good reason on an SPV wallet to sync before the seed was created.
kryptoshi05/10/2019
Cool. Glad you are looking at speedup options.. :right_facing_fist: :left_facing_fist:
[Dev-Happy] Blondfrogs05/10/2019
@MrFanelli™ If the binance dex support RVN deposits. I am sure you would be able to send from it
MrFanelli™05/10/2019
Has binance reached out for any info or anything?
I seen that we ranked in some voting competition they had on twitter
for an ama
Rikki RATTOE Sr. SEC Impresantor05/10/2019
I believe we'll need to create a fund of approximately $300,000 in order to get a BNB-RVN asset created and listed on the Binance FDEX
[Dev-Happy] Blondfrogs05/10/2019
In order to work with binance we need Ravencoin integrated into Blockbook.
Tron05/10/2019
@MrFanelli™ I've reached back out to Binance on the AMA.
MrFanelli™05/10/2019
Awesome :smile:
kryptoshi05/10/2019
@Tron you are a natural on the interviews... cool as a cucumber. :sunglasses:
Tron05/10/2019
Thanks @kryptoshi
[Dev-Happy] Blondfrogs05/10/2019
Cool. We are done for today.
Please don't ask us any more questions :smiley:

HD address generation seems to work in bitcoin 0.13.0rc1 :-)

"The only people who should be running fully synchronizing nodes are miners and businesses and uber-geeks like theymos who enjoy fiddling with technology."
Gavin Andresen
Compiled bitcoin-0.13.0rc1 from source on Ubuntu.
Like in older versions, there was no menu visible in bitcoin-qt (it was in the binaries) but I finally solved it through:
sudo apt-get remove appmenu-qt5
I then added the following code:
https://github.com/bitcoin/bitcoin/pull/8206/files
so I could dump the extended private master key (xprv....)
and recompiled.
To dump the wallet (that here includes the master key):
In bitcoin-qt: click help, then choose console
walletpassphrase passphrasehere 60
dumpwallet filename
I then checked some of the addresses generated in bitcoin-qt here:
https://github.com/bip32JP/bip32.github.io
Substituting the BIP32 Extended Key and using:
Custom Path: m/0'/0'/0' (for the first address, etc.)
THEY AGREED!
(edit: and also the private keys)
Thanks, core developers and especially:
Jonas Schnelli
It's nice not having to worry anymore if the backup of your (encrypted) wallet.dat file has become outdated.

How secure is a HD wallet using BIP39 wordlists?

I've been reading up on HD wallets used by the likes of Trezor, Ledger and a bunch of others (see http://support.ledgerwallet.com/knowledge_base/topics/how-to-restore-my-backup-without-a-ledger-wallet as an example).
I'm no cryptographer and the content in github seems pretty convincing, except that there is a common BIP39 dictionary of words used by BIP32 HD wallets, which effectively provides 2048 words x the length of the mnemonic (12 words, 24 words etc).
This to me then suggests there is a finite amount of HD wallets available - specifically (24 words x 2)2048.
I'm aware that in bitcoin miners are incented to do the right thing rather than try to crack a private key, but why wouldn't someone instead try to brute force all the possible HD wallets in existance? That would surely provide more loot to someone motivated....

Some (or a lot) of ease of life suggestions

Hello! I am back again and after experimenting and tinkering with various different bitcoin wallets, I feel like GreenAddress has the most potential and I want to help, so here goes:
1) A fingerprint-free mode: This is something that electrum and carbonwallet does best for someone who's paranoid. What it does is that you don't have an "account" on the server, but rather your wallet are generated on the spot through your mnemonic, and in GreenWallet case, its your mnemonic + server BIP32 public key.
-> Pros: - In case the server gets hacked, the user's private information isn't exposed (especially if they linked their social media account).
-> Cons: - Lack of 2FA since 2FA is tied to an account. This can be circumvented by having the user input what they want to set as their 2FA whether it be email, SMS, or Google Authenticator, then whatever they put in becomes part of the mnemonic seed (kind of like the encrypted seed) during account setup, so in order to login and access the account they'd have to decrypt it with their 2FA first.
2) ..nLockTime, something that should be a useful safety net becomes something really cumbersome for an average bitcoin user by having to download and update their nLockTime.zip every time a transaction occurs, and it becomes a nightmare for bitcoin miners who receives periodic rewards everyday. I know you can ignore this feature but it clogs up your mail box and if you disable it, you can't recover funds if the server get hit with an asteroid.
Which brings me to the only reasonable solution: 2of3 multisig, ..dun dun DUNNNNNN! But rather than asking the user to save some long xpriv616Aw.... key, they can simply save an encrypted mnemonic version of it, then they could write it out on paper or remember it. And the best part is, the recovery process can be done through the same UI by simply prompting for the backup seed if they can't reach the server.
P.S. I know you already mentioned this feature is being worked on as part of subwallet but it couldn't come any sooner!
3) Longer PINs (say 4-12), can't see why not.
4) Sending to multiple addresses at once. (You can't even bypass this currently because the server forces you to wait for previous transaction to get confirmed before sending another).
5) Online storage integration like Google Drive and Dropbox. Instead of having GreenAddress sign our transaction, we could optionally encrypt and store it on a secure google drive and use it's API to sign transactions for full independence from GreenAddress, still be secured as an attacker would have to compromise both your computer and Google themselves. Just a thought.
P.S. I'll be back with more suggestions muwahahaha!
