[ANN] Blacknet BLN | Staking | Future of zApp & ZeFi

[digit]

I'm wondering if there is any way to force the staking mechanism to stake certain coin blocks ahead of others, especially when the coins are much older in terms of coin age?

I don't understand why I have many coin blocks (~42,000 coins in total) that last staked between 2 months (June 2015) to 1 year (May 2014), according to what's showing in coin control.  

reservebalance could be used to block larger inputs from staking set it to a value lower then your total balance and only the inputs that fall under the difference between the reserved amount and your total wallet balance will be allowed to stake.  
another thing i've noticed is BLK wallet needs to left open longer now to stake, no more "instastaking", have to let it run and node for a bit.  i think this was another improvement that was added to last release so as to reward those that provide better support and protect the network.

the problem is that these 42,000 coins are in multiple different blocks which range from ~1 BLK to 100+BLK so unfortunately reservebalance won't help. Also, when I set the reservebalance, this increases the time to stake since the reserve amount is not counted towards my coin weight. thanks for trying though! You're right that there's no more instastaking though. This was changed in PoS v2 where the coin-age was eliminated from the stake weight calculation. The stake weight is now based on the total amount of mature coins in the wallet. Coin-age still factors in the PoS reward calculation however. I'll pose this question at the subreddit and see if anyone else has any ideas...

u have reboot your machine?

or

sudo ntpdate -u ntp.ubuntu.com

i think thats the problem

blk have %1 per year
so it means in many years ... infinity amount of blk ?

[Subtuppel]

blk have %1 per year
so it means in many years ... infinity amount of blk ?

theoretically. I would assume that the 1% more or less equals the amount of coins that get "lost" over a year, though.

[digicidal]

I would actually assume even higher for the lost coins (probably close to 1% are sent to bad addresses alone over the course of a year, and crashes without backups, forgotten passwords, etc. another 1% probably).  The cumulative growth is certainly much less than 1% of the total mintage when you factor in the huge number of coins sitting on exchanges not being staked and the similarly significant number in paper wallets or other cold storage that are forgotten for more than a year at a time.

My guess would be that moving forward, 'inflation' of 1% will probably look more like 'deflation' of 2-3%.  At least until a time when there are a ton of places to actually use BLK (or any coin for that matter) regularly as opposed to simply holding/trading.  Basically, until you can buy gas, groceries, clothing, music, etc. crypto is fundamentally only a vehicle of speculation and an academic/social experiment.  Hopefully that will change, but at the moment it is what it is and nothing more.

Wallet Obsidian Dev & Erik Voorhees at Digital Economy 15

Wallet Obsidian developer JP Richardson will be a panelist with Erik Voorhees at Digital Economy 15 on Friday, October 2, 2015 in Omaha, Nebraska, USA.

http://digitaleconomy.io/

Coincidentally, Erik recently mentioned Blackcoin for its privacy features. https://youtu.be/Ilnb7Mx0nBQ?t=5m8s JP developed those privacy features including stealth addresses and custom stealth pseudonyms for Wallet Obsidian. That panel will certainly be include some fascinating discussion! You can be sure privacy issues will be discussed and hopefully BLK can be part of the discussion.

Please join us to support JP, Blackcoin and digital currencies generally at Digital Economy 15.

Please consider showing JP some support:

ShapeShift has added a buy/sell feature to the real time market data website CoinCap.io! You can now buy or sell Blackcoin straight from the market data website. Learn more about this here: http://bit.ly/1UVFZ7m

I downloaded the binary for Linux and when I try to start it it fails with this message:

Code:

symbol lookup error: ./blackcoin-qt: undefined symbol: _ZN6QDebugD1Ev

Help!

Update: Unfortunately the old version doesn't work any more because the new version re-indexed the blockchain before it failed. I advise everybody who wants to try the new version to make a copy of their blockchain.

So were you able to launch the new wallet? How it failed? Any error messages?

Nope, the wallet didn't open, it failed just before it opened. This message appeared in the terminal:

Code:

./blackcoin-qt: symbol lookup error: ./blackcoin-qt: undefined symbol: _ZN6QDebugD1Ev

[Mig-23]

until now i still confused how many total coin of blackcoin?
is dzimbek still here ?

And what's up with your build error?

[rat4]

until now i still confused how many total coin of blackcoin?

Currently there's about 75M and it's scheduled to grow indefinitely.

[Subtuppel]

Currently there's about 75M and it's scheduled to grow indefinitely.

As Mig-23 seems not familiar with the specs of BLK i want to add this: There is no limit but it will grow at a very moderate rate, i.e. 1.0% per year. As mentioned earlier in the thread, that is probably less than the amount of coins that are lost over the course of a year (but won't disappear from the grand total, of course).

A long long time ago i've been active on r/blackcoin reddit
maybe you can find my name on there
but always forgot when want to asking about this (total coin)


@rat4 and subtuppel,.thanks for the respons

Oh, that was my own fault. I erroneously tried to build it with Qt4 but it needs Qt5 (I'm not a programmer). I just tried again and here's the latest error log:
