Problems with crypto-mining

Sometime ago we deployed infrastructure for signum coin (formerly called burstcoin) and we posted an article talking about this.

We deployed two miners with 10GB allocated to each one and an instance of signum pool in our machines which was pointing to our signum coin wallet server (full node).

Due some ISP outages, and because mining in the same intranet, we found out that the transaction history in the wallet was forking (bifurcating) from the official network which was requiring to deleting the database of the wallet and resync from scratch because there is no rollback mechanism. Because the isolation problems due the ISP outages, in some other cases, the miners were credited because they found hash for the next blocks, but the payment was blocked because network mismatch.

Because these problems, we are placing on hold the availability of the pool, but we will eventually make it available soon. The wallet server is under resynchronization these days.

Mining Signum crypto

As part of our cryptocurrency experience, besides mining MintMe coin (fomally Webchain, similar to old Monero [web minable] and Ethereum [ERC20 & ERC223 Smart Contracts and DApps], more information at, we’re mining Signa coin (Signum crypto, formally Burstcoin). The website of the project can be found at

What is special about this cryptocurrency is it uses assigned hard disk space for mining instead of calculating once and again hashes. This strategy is called proof-of-capacity or POC in short. These hashes are calculated initially in a process called “plotting” and stored in any hard disk of yours as files, then the miner will scan the files looking for the right hash. The file creating process is slow enough to avoid cheating the assigned space by calculating it again each time the network wants to mine the next block. The files can be distributed across the different hard disks connected to your machine, even through USB and network shared folders. As much assigned space you have, as bigger the chance you get mining reward you will have. Moreover, alternatively to the assigned hard disk space for mining, you can commit Signa coins as part of their stake mining approach (it’s called POC+).

We’ve setup an instance of full node and online wallet in, so you don’t have to download and install any software in your computer (by the way, downloading the full chain takes quite a while), and we’ve setup a pool for small capacity clients in

This cryptocurrency requires to pay some Signa coin from your account before starting mining, because you will need to announce in the blockchain who is going to get the reward in your behalf (if you are mining “solo”, that will be your own account, in case of a pool, the pool owner, in case of our pool, this account is S-3FLD-CSBP-GT8C-9SB84).

To create an account is as easy as to open the wallet and input a long text as password. The account ID is created from this long text. Alternatively you will get a numeric value too that identifies your account.
