Thanks for this.  My code returns the same address now that I have the proper derivation path.



I'm guessing Electrum would find "abandon about razor" to be valid, but according to the source code, it will return a failed checksum if the mnemonic is less than 12 words before actually calculating the checksum.  I have next to no experience with Python, so following the code has been difficult.  Nowhere could I find the m/0'/0 derivation path that leads to p2wpkh addresses even after HCP demonstrated that was what is used.  I guess it would be nice if the derivation paths were clearly set as constants in the code.  Thanks for your help.

I've tried m/84'/0'/0' , m/84'/0'/0'/0' , and m/84'/0'/0'/0 with valid Electrum segwit and BIP39 mnemonic "abandon about razor", but I'm not getting the same result as Electrum (bc1qp0efh7jms7f580e7nnywjg5vzm90njm0rdvqpe for index 0).  Everything matches the results from BIP84 in Ian Coleman, so I'm not sure what's going wrong here.

Well this is dumb.  My code was generating the uncompressed addresses, not the proper compressed ones.  m/0 is the proper derivation path for standard p2pkh addresses.  

I'd still like to know what derivation path Electrum uses for segwit bech32 p2wpkh addresses.

I'm trying to make a version of https://iancoleman.io/bip39/ in java for my own use (mostly to learn about HD wallets).  I seem to have gotten it down, except for Electrum-generated addresses.  Here's what I know about Electrum's differences:

1. Electrum uses a version system that only allows certain mnemonics
2. When generating the seed, Electrum concats the passphrase to "electrum" instead of "mnemonic" to generate the PBKDF2 HMAC

It took a few minutes, but I found a 3-word mnemonic that is both BIP39 and Electrum (standard) compatible: "friend deposit glove".  If I go to New/Restore wallet and choose BIP39 (no passphrase), it generates the same as Ian Coleman and mine: 1BPEpJbnex8z19J9eDfbMakD7d5b9fa5KX (m/44'/0'/0'/0 index 0), etc.  However, if I just use Electrum standard with no passphrase, it generates 1N3UPoVAkX7pQanefb8aAAZGLrMpxC1EYX.  I'm not getting that with any of the following derivation paths: m/0, m/0', m/44'/0'/0'/0.

So, I have 2 questions:
1. What are the default derivation paths Electrum uses?
2. Are there any other internal differences for generating addresses like #2 above?

I'm trying to follow the source code, but it's a lot easier to write code than read it.

Does anyone have more links to the latest articles about the status of this?

This.  I'm guessing that this is a ploy to increase the price of MNE as people will want the "free" Dynerium they get if they buy MNE and hold it for a couple of weeks.  I mean, what else does this token DO?

Cryptonight coins are still really good for CPU-only miners.  I've mined Monero off and on.  Is primecoin still CPU-only, or has it moved up to GPUs, etc?  It's not worth too much, but if you only have CPU...

I use https://tokenmarket.net/ico-calendar.  It's simple and neat compared to others, and gives the websites for each coin.  Only thing it's missing is the coin's bitcointalk announcement thread- hope they add that.

You generally want to hold new tokens for a while to see where the market is going.  Is OHNI on exchanges anywhere yet?  You can always send them to other addresses if you want, but don't just dump coins.

Everyone here is saying ether is one of the best to mine.  You'll need at least 3GB of RAM (probably 4) on your GPU to even be able to mine it, and that has nothing to do with hashrate.  There are a lot of things to consider when getting into altcoin mining, and it might be helpful for you to post your specs.

I think that it has become very difficult to get into crypto over the last couple or three years simply because of the rapid price increase.  That's great for early adopters, certainly, but now prices are so high even on some of the best altcoins that those with less resources will have problems entering the crypto world.  That's not to say it's not possible to buy some relatively cheap new altcoin that eventually skyrockets, but that's a lot easier said than done.

I can only wish bitcoin was only $500 now!  But maybe the OP's currency isn't USD?  Not sure which currency has a 1:10 exchange ratio...

There are certainly some good ICOs out there with innovative ideas and technologies that really do need the money to get up and running.  There are also plenty of scams, and they can be hard to spot.  Always do your research, including looking up the team members' social media pages to see if they are legit.  And of course, never spend more money than you can afford to lose, even if it isn't a scam and simply flops.

Thanks for this- been looking for a good site.  This one is pretty comprehensive and clean compared to others.  I just wish it including the bitcointalk announcement link for the tokens!

This has been done before, and stealing people's CPU time has never really been accepted as a valid way to make money for a site.  Then again, it's not like downloading the ads isn't stealing your bandwidth.  You can block both ads and scripts these days, so if you really don't want to participate, you don't have to.  Sites should be up front about mining though.

It is a broad question, and it's initially more about the potential of the coin and its technology than its value- is it an innovation that will be useful longterm?  Of course for ICOs, they do put an initial value on the coin to raise the capital they need to get the project off the ground, but once it hits the markets, all value is defined by supply and demand.

I hate scammers, and there have been a number of ICO scams that have stolen a lot of money.  While I'm not sure that the Chinese government is putting an end to ICOs out of the goodness of their hearts to protect their citizens from scams, I think that some regulation in this area is good.  It will make scammers think twice about the value of starting an ICO just to rip people off. In the end, if someone in China really wants to join an ICO, they will find a way around the restrictions.

I first got into it years ago for the technology- it was very interesting and revolutionary.  Of course over those years the price has grown exponentially, so I'm also now interested in the monetary aspect of it   I've never really been involved in the "screw banks" ideology part of it though.

Ethereum does have some advantages over bitcoin, including faster transaction times and lower fees.  It is entirely possible now that bitcoin is having troubles with those two things that other cryptos like ethereum will significantly increase their crypto market share.

Let's not all freak out just yet.  People will find ways around this, including the VPNs and TOR.  If those are blocked, I'm sure a lot of bitcoin users will simply move if they have to and still value bitcoin.  I'm not entirely sure why China is cracking down on bitcoin so hard- anyone?
