Is everything OK with the blockchain?

Block Explorer shows the last found block has a TimeStamp of "Thu, 01 Jan 1970 00:00:00 GMT"

Blocks are not beeing found.

Anyway, the wallet was acting strange on the server so i put the Pool Offline.


As soon as this issue is fixed i'll put the Pool back online


Hey, thanks for writing here. I've also noticed this odd transaction, perhaps it's some type of exploit - http://smartchain.cc/tx/a6d85e1ec17873f90dfe5e8270cfe90a2f5f70cb493e7161b82f415aad8c39bb

Nothing has changed in a while as far as the source code is concerned, and I have seen this before too, about a year ago, so there shouldn't be anything of critical concern. If there was a way to spend such malformed output, it must have been done already, but I don't think there is, because the tx is not part of a block. It's just a kind of spam. I have put this on my list of issues to investigate further.

I have also noticed other mining issues, however. For example, the pool at smc.e-pool.net:8960/static has been generating shares that were 97% "dead on arrival", but this seems to be a pool issue because at the same time (2 days ago) the Miningfield pool was working fine.

The main issue with SMC mining has been that a large amount of hash rate switches into high gear and then disappears once the difficulty has been raised. (Blocks were probably not being found as usual because of the increased difficulty.) This is a well known type of vulnerability, but one that should not be occurring with a sufficient amount of dedicated hash power always available to the network. I have been looking for a Baikal miner in order to resolve this, while renting X11 rigs to mitigate the sync delays that have been happening in the meantime.

I think it should be okay to ignore the invalid tx and bring the pool back online.


Pool is back Online

http://smc.miningfield.com

yesterday the wallet was generating a lot more load on the server, and a simple "getinfo" would take 15sec to get the output, a wallet restart would not solve the problem.

I don't know if it was some kind of attack, i've been having the wallet running for 2 hour now, and had no performance issue so far, so i'm putting the Pool Online.

Block explorer still shows that strange block as the last one, so i don't know if there's a bigger issue behind this.

Also Network Speed seems to be stuck.

Let's wait for another block.


New Blocks have been found.

Everything OK on the Pool, and block explorer is following blocks.

I would say it's back to normal.

== Short Term Roadmap ==

* Update wallet release to the 0.10 core
* Android wallet

Then back to the portfolio manager / algo trader

Other possibilities for development:

* Electrum server for running wallets that don't need to download the blockchain
* Trezor or other hardware wallet support
* Web wallet
* Mining changes, permanent 1% tail emission to ensure there is always incentive to confirm transactions



Nice, thanks for keeping us updated dev.

Must be a promising project. Investors must be holding, not a lot of sell orders on Yobit nor Cryptopia.

Have been doing regular updates to the portfolio tracker. Added coinmarketcap as an additional source of info.

thinking out loud.

A. create an ICO, tokens given in exchange for SMC.
B. repeat.
C. repeat.

in #blocks per halving? do you know?

epoch0 r=32 @block#1
epoch1 @block#999999 r=xx
epoch2 @block#999999 r=xx
epoch3 @block#999999 r=xx
epoch4 @block#999999 r=xx
epoch5 @block#999999 r=xx
epoch6 @block#999999 r=xx
etc


Not sure I understand the question, but here is the updated schedule. It's the same as it has been, except that the 8, 4, 2, and 1 rewards actually have a longer time frame. Updated schedule:

Next SMC block halving is in ~10K more blocks, sometime in early April. This would reduce the block reward to 4 SMC.

Going to have to think about how to run the network in the long term when there are no block rewards from coin base. Perhaps having a miner on standby that runs only when a transaction is sent could work. That should be more efficient for a network that doesn't have a constant stream of transactions, than generating new coins all the time. The other option is a fork for a 1-2% tail emission, which could work better. Lots of time to think about this, a few years, but it should be resolved ahead of time.


Looks like the calculations in the OP following the last block halving are not quite accurate. Instead of halving every year after 562,800, it halves every two years.


The line

Code:
    nSubsidy >>= (nHeight / (forkBlock3 + 262800));

should have been

Code:
    nSubsidy >>= ((nHeight - forkBlock3) / 262800);

in order for the halving to be every year.


So the next halving is actually a bit more than a year from now.

I picked this coin as a "super secret" coin to accumulate earlier in the year. Very cool to see how you're carrying on this legacy blockchain, psionin.

It became a bit of a guessing game to talk about it indirectly with people trying to figure it out. I hope it create a little buy action and value to encourage some more work on the portfolio app, which I think is absolutely awesome.

dm me on Twitter if you want to talk, dev!

Hey, it's great to hear such feedback. I've actually been using the portfolio manager myself, and it's been quite helpful in tracking a bunch of different coins at once without having to keep looking them up and reloading pages. There didn't seem to be much interest about it at first, but maybe now it can be moved to the front burner.

As for SmartCoin in general, my goals have been to keep this thing together as an autonomous, decentralized, and open project, and to make it easy for anyone wanting to participate in a beneficial and constructive manner to add their contributions, if they fit in and make sense, while ensuring that basic underlying functionality (such as adequate exchange listings and fast blockchain synchronization) remains in place.

For a while, there may have been some doubts about the nature and purpose of this project, such as when too many alts were being made and taking up investor attention, or when the idea of Bitcoin being the only real cryptocurrency was becoming widespread. It is now more clear that scaling the crypto ecosystem cannot happen with Bitcoin alone, and that alts are very much needed in this growing economy.

In regards to the question about future updates to the node code, it is certainly possible and may be done, but it is important to be cautious and make such changes count. There is also value in blockchain immutability, and it is arguably better to keep a stable version in place rather than to have potentially conflicting updates on the network. So first and foremost I think it is important to recognize that SmartCoin is already successful in the state that it is in right now, that it has the same type of "digital gold" properties as Bitcoin, and that it could be relied upon to function and provide a means of value storage and exchange in the years to come.

This is exactly the kind of thoughtful response I had hoped to hear. I know with the recent high-valuation of masternode coins (DASH and PIVX) there is pressure for legacy blockchains like Smartcoin's to attempt to capture some of that price-hype by an encouragement to hardfork to include that system ("because it's already x11" or so the wishful thinking goes). The truth is, more long-term value is built on staying the course of what has been planned for the coin from the beginning, and leveraging its best assets (name, simplicity) as you have already been doing.

I'm glad you chose to keep Smartcoin and its related assets alive through the 2015-2016 period you mentioned when altcoins in general were overpopulated and overextended. As the illegitimate projects fall away into segregated, speculation-only markets like Yobit, there's much potential for a re-evaluation of legacy blockchains like SMC which have stood the test of time.

Specifically, I've always hated the time I have to spend updating my portfolio spreadsheet manually. I don't have the technical chops to have each field complete the api call to each coin's block explorer, and I'm sure each explorer works differently. The closest tool to what you've created is the Coinigy Marketwatch app, and though it allows you to enter an altcoin's address manually, it doesn't scoop price or quantity information from any exchanges, and thus doesn't work (except as an aggregator of your balances across supported exchanges). If Smartcoin's hold-to-unlock live portfolio manager could allow for address entry of any altcoin listed on Coinmarketcap, that would be amazing. Even a tiered price model where one would need to hold 1000 SMC for each five addresses whose balance the tool would track, would be fantastic.

In any case, thank you for your response and your continued attention. Anytime you want to contact me for help or discussion please feel free!
