Hi, your electrumx servers have their certificates expired. That is why there are issues with FJC on AtomicDEX

06 00:10:53, coins:rpc_clients:1850] ERROR "electrumx1.fujicoin.org:50003" error Custom { kind: InvalidData, error: WebPKIError(CertExpired) }
06 00:10:54, coins:rpc_clients:1850] ERROR "electrumx2.fujicoin.org:50003" error Custom { kind: InvalidData, error: WebPKIError(CertExpired) }

you should renew the certificates and reload the service

Any more news and exchange for Blackcoin? A little bit silent about BLK  Huh Huh

Exchange charge absurd amounts of listing fees. Currently there are no funds, because Blackcoin depends on donations.

So first of all the community has to grow, more people have to start staking again.
Currently around 8 million coins are staking (out of 61 million). So the people that are staking, get a nice return of around 8% at the moment. but that the trading volume is very low on Bittrex atm.

Blackcoin has always been about the community stepping up and taking responsibilities by creating social media posts, youtube videos, artwork, blog articles, etc. But also that kind of advertisement is almost non-existent.
The most people that want to help, are offering "promotional packages"! There are some exceptions, en those people are currently keeping the project alive.

We also see a shift to a more non-technical crowd. People want to know how Blackcoin fits into NFT, DeFi, BSC, etc. There is currently no roadmap on these kind of things. Basically because there are not so many devs around. 

It is silent around BLK, that is true. But you can create as much noise as you want.

In the background some folks are still working on a daily basis to keep creating the future of Blackcoin.  Some things that are still running and going on

- The next big upgrade on the Blackcoin More wallet (BTC Core 0.21 based)
- Discord tipbot - join us at https://discord.gg/hjNUgWD
- PayBLK webwallet updates
- BlackSight updates
- Electrum servers
- DEX additions (Atomic swap based)
- CEX additions (hoping for free/cheap ones)

And I am probably forgetting some things.

What we need
- Get more people to stake. Get the coins of the exchanges.
- Blog articles on how-to stake, how-to invest
- Basically people that like to help, create and learn about Crypto :-)

You should consider a *trustless* bridge to Pancakeswap or Uniswap.

Can you help with that? we have been looking at BSC too..

Hello,

First of all I want to say that your service is very good. The new new features that show mining and staking transactions are one of the features I use the most.

I did noticed that for some reason this not always show up correctly.

For example this address https://chainz.cryptoid.info/blk/address.dws?BSKLBUSf9eWEmB66zTAoxvd89ESTKuGwHn.htm shows the coinstakes as received
but this address https://chainz.cryptoid.info/blk/address.dws?BGVZa37Fdh8jxU3EuJfndLL6GtY1unywt5.htm does show the coinstakes as stakes!

I am trying to understand if this is related to our software/blockchain or something on the CryptoID platform, maybe a change?

Thanks

Michel

Hello Blackcoin community members,

Please update your Blackcoin More wallet to the most recent version, released on Feb 24th 2021
version v2.13.2.8-10bb345e7 has been released and will solve the Atomic Swap bug.

As soon as the majority of staking wallets has been updated, services like AtomicDEX can add BLK to their service!

If you still run the older v1.2.x wallet or BlackHalo, there is a big chance you are not able to sync anymore (or even forked).
Please migrate to Blackcoin More! how? https://blackcoin.nl/dump-and-import-wallet-private-keys/

You can download Blackcoin More from https://blackcoinmore.org

For (support) questions please visit our Discord https://discord.gg/hjNUgWD

so is this coin still going?

I used to use it back in 2016.

Thanks for the update.

still going!

Still going down (vs BTC).

That is correct

I guess that nobody is talking about the Livecoin scam and the amount of BLK on that exchange because nobody is interested anymore..

Hi, People are talking about this, but most of the Blackcoin community activity is on Discord these days. Please join us https://discord.gg/hjNUgWD

It is also not clear how many BLK are on that exchange or if they are already dumped on another exchange, like Bittrex.

I haven't heard of anyone with BLK on Livecoin, but myself. I have a small amount there. (sub 500BLK)

My calculation on this topic.

A successful mint matures for about 10 houres. With one minute medium block interval it's 600 blocks in total. After 600 blocks they can mint again.

We have a total of about 77 Million coins. If they would mint alltogether in an even way, the absolute maximum fragment size would be 77.000.000 blk / 600 = 128.000 blk.

Not all are minting, of course, and some coins get lost, so the optimal split size should be much lower than 128k. To be cautious, one could double the size from time to time until it fits. So the devs could double the split size from 1k blk to 2k blk on a next release.

Regarding this and the attack, not only the processor load is affected, but the resident memory load too.

Lets see.. We actually have 60 million coins. And normally around 15-20% is used for staking. How does this effect your calculation?

edit: 500 blocks for a stake to mature and 67 seconds block interval

On many PoS coins the processor load rises on small transaction sizes. If this is not the case with blackcoin, it's ok then. If the load is an issue, then the fragment size could be ten times larger, between 5000 and 10000 BLK.
[/quote]

So, it is true that the processor load rises on small transactions. But as far as I know, the staking process is single threaded. But it is a very good question, and if you want you can try different stakecombine or stakesplit configurations. There is the possibility, but it is currently hardcoded in the code.
You would need to alter the code and compile it yourself (or send an PR on Gitlab and we can compile it for you)

the code is here
https://gitlab.com/blackcoin/blackcoin-more/-/blob/master/src/wallet/wallet.cpp#L50

and from here on
https://gitlab.com/blackcoin/blackcoin-more/-/blob/master/src/wallet/wallet.cpp#L801

We are currently trying to combine inputs, so it will always contain an x amount of dust txs. (lets say 100 inputs <= 0.004)

Thanks!

This combine could help, but it can only be useful, if the fees/costs for it are less than the fees/costs for the attacker.

I testet to combine by hand, but the fees for it are much higher than the input.

A Coinstake transaction doesn't have fees, but it only happens when you win the stake

Is there any possibility to configure a stakecombine or stakesplit?

Can you give an example how that would like?

Staking leaves a lot of dust in the blockchain, consisting of many 0.00005500 BLK parts.

It is not the staking that leaves a lot of the dust. The wallets that are staking are being attacked with dust transactions.

The Blackcoin network is being attacked with spam/dust

check out this post
https://blackcoin.nl/a-dust-attack-affected-legacy-blackcoin-clients-in-late-sept-2020/

thanks

It is important that people upgrade/migrate to Blackcoin More v2.13.2.6 and (optionally) raise the fees to avoid relaying these transactions. We will have to raise the fees in the next version to mitigate these attacks

Next More version will be v2.17.0 and is based on BTC Core code 0.17.

More can be downloaded from https://blackcoinmore.org

Blackcoin and Radium Core devs form a strategic alliance. Both blockchains share similar codebases so it makes sense to collaborate:

-Work together on future codebase upgrades
-Share industry knowledge
-Innovate PoS technology

The core wallet has a memory leak, the linux version at least. It exists for a longer time, and consumes about 15-20 MByte for every block PoS minted. Would be nice to get it solved.

Hi,

We are actually working on that. If you have ideas about the issue, please let us know!
