[ANN] Datacoin - Censorship-Free Data Storage

[Chicago]

Hello DatacoinMiner,

2.
Also, the wallet has another known bug, wallets from that era cannot handle many transactions over time.
As a miner, I get many transactions a day from mining, something that is commonly called "dust."
Due to this, my wallet can no longer do transactions over about 7000 DTC - it gives me an error -- I believe it's a coin control problem.
I also believe the 0.10.x versions have overcome this?
DatacoinMiner

    If you see a "Transaction too large" message it means you're including too many inputs in the TX.

Code:

/** The maximum size for transactions we're willing to relay/mine */
static const unsigned int MAX_STANDARD_TX_SIZE = MAX_BLOCK_SIZE_GEN/5;

/** The maximum size for mined blocks */
static const unsigned int MAX_BLOCK_SIZE_GEN = MAX_BLOCK_SIZE/2;

/** The maximum allowed size for a serialized block, in bytes (network rule) */
static const unsigned int MAX_BLOCK_SIZE = (1024 * 1024);

    In other words, the largest standard transaction permitted by the consensus protocol is 100 KiB.

    This feature is by design.

Best Regards,

Hello, extro24, feddern,

@feddern, [27.01.18 23:51]
so a clean bootstrap that is up to 2.2 mill etc would be good to have

    A linear bootstrap.dat for Datacoin up through the current height would be great.
       
    I think dtc2017 may have an adapted Linearize script for XPM which renders them.

Anyone aware of a bootstrap for dtc? If not I will make one available

https://github.com/dtc20017/Datacoin-Bootstrap

    Usually, producing a no-fork version of the blockchain is trivial, but Datacoin complicates things a bit w/ the XPM hashes.

    The thing holding me back from publishing an updated bootstrap.dat is finding a python XPM hashing module to plug into the upstream Linearize scripts.

Thank you for that information Chicago.

Question:
Why was I able to send transactions over 7000 Datacoin previously, but now I can't anymore?
I used to be able to send transactions much much larger than that, but now I get that error each time.

Hello DatacoinMiner,

Why was I able to send transactions over 7000 Datacoin previously, but now I can't anymore?
I used to be able to send transactions much much larger than that, but now I get that error each time.

    When you run listunspent from the Debug console, you'll see the coins there which get used in new transactions.

    As an exercise, if you want to list a handful of them with the lowest value and most confirmations, we can help you work through handling them.

    Another exercise you can do would be to send many transactions of yours aggregating the smaller coin into a new output.
    For example - sending a bunch of 0.001 inputs to a new address - and then spending the new output easily.

Voting for Next Exchange

Thank you everyone for the help in getting Datacoin listed on the FreiExchange.  This coin is going somewhere!

Thank you everyone also for the sterling vote on the Next Exchange.  With almost 900 votes, we are lying in the 28th position.
Please comment when you vote.    This is very important, to give the exchange an indication of the views of the Datacoin community.
I do expect that we will make it onto the Next Exchange.  I have that good feeling again  

-extro


EDIT:  We now have 932 votes on Next Exchange and we are lying in 23rd position out of 408 coins.

You still can, actually. It's not the total DTC that's the problem, the limitation you are encountering is on the number of txs that need to be assembled to amount to that sum.

In essence you are (or rather, your wallet is) trying to send 7000 DTC in small change and you are hitting a hard-coded limit. The recommended answer is simply to send a number of smaller amounts. However, if not being able to dump your stash in a single tx is bothering you, it's easy enough to move away from at the cost of a few tx fees ...

Create a new receiving address in the wallet and start by sending a smallish amount to the new address, say 50 DTC , Then repeat, trying with successively larger amounts, try 100, if that's okay, try 500, if that works, try 2000 (best to aim high as it results in lower fees overall). If the collating tx fails, halve the amount sent and try again. Ultimately you'll be able to send the entire bagtotal in one tx but you can stop as soon as the max tx amount starts to look sensible for your purposes.

There may be some coherent documentation somewhere of the how and why of “coin control” but I haven't found one yet.

Cheers

add the command -upnp to your qt wallet and it will use upnp on your router for port forwarding

Hi,

Did you try other miner versions?
Did you try deleting old kernel file?

[MarcusDe]

No, it isn't problem.

To what IP dtc.graymines.net resolves?
Should be:

Code:

$host dtc.graymines.net

home.graymines.net has address 89.76.251.96

Hi,

Did you try deleting old kernel file?

I have try these 3 versions, same error report "Failed to ADL..."
Miners:
version 10.1 beta,  
version 10.0 beta,
version 9.4.1

----
I have try others miner for XMR\ETH\ETC  ,they can work ,no error report

[nanadipa]

what kind of old kernel file should I delete? I dont know, please tell me more details

Is there any others version miner I can try ?

[Wirel]

I guess, because its also a problem i have, that the issue could be the INTEL GPU which is platform 0, miner tries to use that instead of discrete card and fails, any opinion?

Whoever is mining atm, use DATAcoin address :-)

When you run miner 1st time it compiles kernel and creates binary kernel on disk, so next time you run miner it doesn't have to do it.
When hardware changes it can cause troubles.

Looks like there's no problem for it, it all looks reasonable and nothing will happen, it's the thing that will not cause any problems.

Yes, Datacoin addresses always start with a D.  This is not a Datacoin address.
Look at the addresses listed by Bytestamp:  http://www.bytestamp.net/blocks/lunsp
