Today, the last few missing pieces regarding the UI will come. I have loaded more on the "test" account btw

Also, I started to work on the "Genesisblock Redeem" function. If anyone wants to join on this one, feel free!
The redeem transaction will be an own transaction type matching a SECP256k1 signature to an entry in the genesis block. To make it simple, I thought it would be nice to add a few "importers" into the ui which will generate private keys from various types of wallets and prepare the require signature automatically.

If so, someone can send back some testXEL? Thanks

Remember guys,
the testnet is not yet "officially" live! Those who have been running the elastic-core development branch will need to frequently do a "git pull; ./compile.sh" as many things still change.

This is the case now: we need to hard fork the pre-testnet! Only nodes with version 0.3.2 are allowed to connect.
A git pull, followed by a recompile is enough in most cases! if problems arise (or if you want to be on the safe side), just redownload the chain by issuing a rm -rf nxt_test_db/

Only test the pre-pre-testnet if you like "hacking around".

wow. Two days away and lot of changes! I was trying to read for last two days but had no time to write something. Actually right now also can't be here longer but I want to just write:

Great work @EK!

and I'll try maybe later this day to download client, update explorer, read posts etc.

Again, awesome job, lot of new code, ideas and great current result. Can't wait to find time for all this stuff.

Hi EK, I've spent some time reviewing the EPL logic and I think I am understanding it.  However, just to clarify, to me it looks like everything is a 32 bit operation.  For example I don't see any carry-save logic in the AddNode module for larger values and the shifters all look to be 32 bit as well.  Is there a plan to add functionality to allow larger operations, or did I just mis-interpret how your code works.

Also, as someone asked before about looping, I looked at the Repeat module and to me it looks like it would repeat a single operation, but not a group of operations, is that correct?

I need to think up a example to try out EPL on so if anyone has any suggestions for a use case, please let me know.

Long diff retargeting times? Did you see this @EK? At new version when XEL-9HQ9-BXCV-TARZ-BRDNA was forging with his big stack he was forging couple blocks per min. When XEL-9HQ9-BXCV-TARZ-BRDNA disappeared XEL-K3TA-MQNB-4NHD-5GE8U is the only one forging and he have trouble to get block in 5 min. Anything changes in that matter with new versions of NXT?

Are they (NXT) was afraid of split (like ETH/ETC)? So they did long times of retargeting to be sure that one chain (weaker) will be long behind?

thats me forging, i believe ImI stopped forging blocks after he submitted work to network.. this is what my logs are showing.

@EK, we still have old problem. When there is some work in the network someone is banned hard (ending on fork). It's easy to recreate this in your env. Just put work after work to the network. you'll see that after some time you'll end on a fork because everyone else will ban you.

I think that you're on the forked chain because I started up my node about hour ago (with testnet peers from config) and my node downloaded blockchain from testnet peers. So we assume that if we downloaded blockchain from @EK testnet peers we are on a right fork. Please try to stop your node, delete blockchain and start it again (since blockchain is young you should download it in two minutes) and see if you are on @EK fork again. If not, I'm on the wrong chain and node which forging right now also.

Give me a result. Thanks.
