Can someone remind me of the current minting stats?

Minimum coinage?
Minting reward?

woolly_sammoth 2015-07-31 10:13:51 UTC #555

I think I’m right in saying that the minimum coinage is 1 BKS (1BKS == 10000 NSR)
The minting reward is 0.1 BKS
edit: Ah coin-age not coinage. ignore that first bit then (I think it remains as 7 days)
damn decimal point too! yup, 0.01 not 0.1

masterOfDisaster 2015-07-31 11:50:11 UTC #556

According to the design document (Section “Use case: Minter and shareholder”, page 19) the minimum coinage for minting is said to be 7 days.
The minting reward is reported to be 0.01 BKS and the minimum mount of BKS to mint is 1.

Nagalim 2015-07-31 12:05:01 UTC #557

0.01 is right, but you only need 1 BKS to mint. The threshold is lower (by 4x) but the reward is greater (by 2.5x) than for nsr.

masterOfDisaster 2015-07-31 12:08:34 UTC #558

Oh, thank you for pointing that out. I misread your post at bitcointalk.org (which clearly states that 1 BKS is required to mint) and have corrected my last post.

willy 2015-07-31 19:57:10 UTC #559

Thanks for all the answers so far.

Which port is B&C using?

I see
tcp 0 0 0.0.0.0:2239 0.0.0.0:* LISTEN 2888/bcexchanged
tcp 0 0 127.0.0.1:2240 0.0.0.0:* LISTEN 2888/bcexchanged
tcp 0 0 127.0.0.1:2241 0.0.0.0:* LISTEN 2888/bcexchanged

on netstat

You should be able to specify a port (if it shall be different from 2239) in the bcexchange.conf

port=xyz

willy 2015-07-31 21:08:50 UTC #561

Oh boy… that sure was the easiest solution. I can stop skimming the source code now
Thank you so much.

masterOfDisaster 2015-07-31 21:10:10 UTC #562

I can’t read code. I need to use other tools

masterOfDisaster 2015-08-03 07:09:57 UTC #563

After successful compilation of bcexchanged on my RaspberryPi2 (and running it stable since then (July 31, 2015)) I’ve experienced different behaviour of “bcexchanged” and “nud”.

Shortly after the daemon is started, bcexchanged is responsive to RPC, e.g.

bcexchanged getinfo

while nud is complaining about “error: couldn’t connect to server” for several minutes. Is this due to the bigger blockchain of Nu? Is there a kind of integrity scan running? Both Nu and BCE wallets are empty. So there’s no need to search for transactions related to keys.
Oh wait - the client needs to scan the blockchain anyway, because it wouldn’t know that there are no transactions to private addresses in the wallet, right? Even an “empty” wallet contains keys…
…but even if that scan is going - why does it interfere with executing RPC commands?

The RAM assignment is very different as well.

bcexchanged uses ~6% RAM (60 MB)
nud uses ~45% RAM (450 MB)

Is that difference of RAM assignment due to changes in the Nu 2.0 code from which BCE was forked?
Would compiling nud from 2.0 code reduce nud RAM assignment?

The B&C Exchange OS X application was announced a few days ago.

PinkyAndTheBrain 2015-08-04 07:22:11 UTC #565

It used to be at 8 connections, but as of late it has dropped to only 1. Still staking so no complaints, but wondering if anybody else has the same issue?

mhps 2015-08-04 07:24:33 UTC #566

My node hasn’t seen any new block past 40421 for 40 min. It has 4 connections including 62.4.15.180 . Is it on a wrong branch?

edit: right after I posted the node connected to a new peer and received 50 new blocks. How often such temperory out-of-sync happens, I wonder.

yep, 1 connection here also

in my conf file?

edit: ok thx

mhps 2015-08-04 08:02:01 UTC #572

Thanks. We shared these two

Our nodes only had one degree of separation at most. How come these two nodes didn’t tell my node about other ones?

Anyway thanks for the list. Having 8 connections now.
