Lonely Highway Delivery Guy accepts GRSJust had beer and meat delivered. Paid with 667 GRS. This 'occasional merchant-trader' is assisted by IndiaMikeZulu. LHDG got her first GRS at 750. Sold the lot at 2500. Now has a bid up for 8500 GRS at 1000. http://imgur.com/a/8BcHZ

Wrote this 'Report' on crypto adoption: http://groestlcoin.org/forum/index.php?topic=477.105Abd something else also came up in the conversation: remember when hard cap was a major attraction of cryptos? Then smart contracts and some other stuff took the limelight? Well, the concern about world debt, which just refuses to lie down, is going to (ultimately) direct attention back to established hard-capped cryptos. Niiiice!

https://www.reddit.com/r/CryptoCurrency/If anyone has a little spare time, there are many newcomers asking on the threads here about the most basic realities of cryptos. We have the strength of solid crypto and a small and sane community -- it's a real asset! EDIT: Wow! Cryptos has pulled nearly $US 5,000 Millions in new capital since I got out of bed this morning. And bought 700 GRS worth of groceries yesterday.

I tried to generate an address with the Groestlcoin paper wallet generator, but the address it gave had a "checksum error". The rivate key also gives me a checksum error too.
Here is the address: Foi3FNkp6f2u1aVyBLpUuQjAtvXvLoQyDz
and the corresponding private key also gives me a checksum error: 5KDcgddMkhPsLFypd1giap5fziz43SazRupaTmLYWvVmcu5YS9g
by any chance did Groestlcoin change the base58 address encoding that bitcoin uses? Why would it give me this error?
Here is the python code I'm using:
>>> from base58 import b58decode_check >>> b58decode_check("Foi3FNkp6f2u1aVyBLpUuQjAtvXvLoQyDz") ValueError: Invalid checksum >>> b58decode_check("5KDcgddMkhPsLFypd1giap5fziz43SazRupaTmLYWvVmcu5YS9g") ValueError: Invalid checksum
This base58 library works fine for other BTC forked coins like LTC, PPC, Doge, etc...

Chris, Did you create the Groestlcoin paperwallet generator online or offline ( http://groestlcoin.org/forum/index.php?topic=314.0)?Groestlcoin is not a normal Bitcoin fork, we groestlized all hashes (not only pow). So yes, base58 address encoding uses double groestl512 instead of double sha256. Our privkey starts with a "5" and multisig/segwit addresses starts with a "3" like bitcoin. But the beauty of it is: You cant send accidentally grs to btc address and vice versa. No more mistakes (like sending ltc to a btc multisig) because we changed base58. A grs address (public/priv/segwit/multisig) ONLY works on grs blockchain. I c you are a python guy so have a look at this commit and you will understand: https://github.com/Groestlcoin/electrumx-grs/commit/b7345bf871f3c9c19674e8b1ec51d644053895ccI verified your generated public and priv key and they are valid! Dont use it anymore tho since you shared the priv key with us.

1) We have the latest wallet. ['version': 2130300] 2) The pool is on UNOMP and is SW ready 3) Don't know how to do this 4) FXud4Lurb8XzGvTAN9EdcDJGMkJuAcRA7k 5) You can’t see that yet, everything is ready and we are waiting for miners.

So yes, base58 address encoding uses double groestl512 instead of double sha256.
I see. If there a reason for this? I can understand why you'd change the POW, but why change the address hash? There doesn't seem to be any benefit to doing that, other than to make it harder for people like me to implement wallets. I now have to fork every base58 library to replace sha256 with groestl512, which I've done here: https://github.com/priestc/Groestlbase58, except i can't find a good Groestl implementation in python, so Groestlcoin will unfortunately remain unimplemented in my project ![Sad](https://bitcointalk.org/Smileys/default/sad.gif)

No more mistakes (like sending ltc to a btc multisig) because we changed base58. A grs address (public/priv/segwit/multisig) ONLY works on grs blockchain. This is to protect our users sending coins to another coin address. What kind of wallet are you trying to implement? If its interesting enough, we can do all the hard work for you. Not sure if u had a look at our github with over 100 repositories. Anyway we use this groestl implementation in python for electrum and bip32utils: https://github.com/Groestlcoin/groestlcoin-hash-pythonExample: https://github.com/Groestlcoin/bip32utils

That what the version byte is for. The first letter of the address is what keeps you from sending currency to the wrong type of address. All changing the base58 does is make it more error prone. If I had not happened to stumble upon the fact that GRS uses a different hash algorithm for addresses, I may have implemented GRS to some application using sha256, which would have resulted in me and anyone using that app to lose money by sending to an invalid address. Is very unusual for an altcoin to change the address hash, in fact GRS is the first I've come upon. I see the bip32utils project you have forked already includes a base58 implementation using groestl. Could you put it up on pypi so I can add it to my project? My project is called moneywagon, it's a cryptocurrency platform for building wallets and exchanges and stuff like that on top of. Also, it seems you also removed sha256 from the transaction serialization code too? If so then another forked python library with groetsl support is needed to make transactions, so the groestl-hash function needs to be added to pypi too. Also I noticed there is a groestl fork of bitpay insight on the groestlcoin github. Is there a pubic instance of this running?

Thats not correct. You could still send accidentally GRS to Fuelcoin, Fluttercoin, Fujicoin and all other coins that start with a leading F symbol. With changing the version byte you can still send currency to the wrong type of address. We need to protect the crypto users. All changing the base58 does is make it more error prone. If I had not happened to stumble upon the fact that GRS uses a different hash algorithm for addresses, I may have implemented GRS to some application using sha256, which would have resulted in me and anyone using that app to lose money by sending to an invalid address.
Not if you build the checksum validator in all wallets like we have. If you would have tried to send GRS to that address then any of our wallets would say: invalid address. Thus the transaction would never been happend. Is very unusual for an altcoin to change the address hash, in fact GRS is the first I've come upon.
I know right? Spread the word. We are unique. I see the bip32utils project you have forked already includes a base58 implementation using groestl. Could you put it up on pypi so I can add it to my project? My project is called moneywagon, it's a cryptocurrency platform for building wallets and exchanges and stuff like that on top of.

Interesting project. This might be usefull info for you: http://groestlcoin.org/forum/index.php?topic=343.0Transaction serialization uses single sha256 (instead of double sha256). A summary what hashes we changed can be found here: http://groestlcoin.org/forum/index.php?topic=344.0Also I noticed there is a groestl fork of bitpay insight on the groestlcoin github. Is there a pubic instance of this running?
PM me for info

Memo from the Night Shift:
Wheee!
Japan and Korea (and India) are the ‘Asian trading-zone’ – which includes Western Australia.
We’re avidly following events here: KRW volume; Korean banks shut for the weekend; are military tensions on the peninsula really driving adoption to some degree?
