Ercoin is a currency with fair distribution, delegated proof of locked stake used as a consensus algorithm and Tendermint used as a consensus engine. Initial Burn Offering has been announced.


Contributions are welcome.

There is already a command for burning coins in BlackCoin and it has not been advertised as sacrilege.

What do you mean by “creating new trade”? How would that work?

I’ve released the code of the cryptocurrency I’ve been writing. BlackCoin burning is proposed as a method of initial coin distribution. Some background is available.

Using that tool, I’ve performed an analysis of blocks 1 to 1697894.

I’ve created a simple Haskell application that lists burnt coins (in particular those created using the recently introduced “burn” command). It is named burnt-explorer and theoretically should work also with other Bitcoin-derived cryptocurrencies, though currently the blackcoind binary name is hard-coded.

Using that tool, the following message can be found in the 9ba558c64985d8452f4f65f47ea873d360e22e5697dcf6185125c4cbfaf4855b transaction:

“Big shout-out to janko33 for bringing Blackcoin to the 0.12 codebase |blackstat”

Besides the source code, a compiled Linux binary for 0.1.1 version is available (for 1 BLK).

Paspagon is a payment processor that allows selling any file stored in the cloud (currently Amazon S3). No registration is needed and customers may be anonymous. A Jekyll plugin exists which allows selling blog posts in various formats.

Due to high transaction fees, Bitcoin is being removed from Paspagon, making BlackCoin the only supported currency.

According to bitcoinfees.info, currently it costs nearly $2 to make an average Bitcoin transaction be included in the next 6 blocks and over $2.3 for the next block. For BlackCoin, it is about $0.000028.

BlackCoin 1.2.4 has been released. Packages for Fedora are available.

After you got block, the unspent transaction output (UTXO) which was used to create a block waits for 510 blocks before it can be spent (or used again for staking). The node doesn’t need to be online during that time, but often you will also have other UTXOs (maybe even from the same address) that will be able to stake, hence a reasonable approach when staking is to keep a node always online — unless you have only only one UTXO with amount of coins so low that this UTXO doesn’t get split when staking.

There is no minimum amount required for staking. Chance of finding the first block is proportional to the amount of coins you have (then those coins will get locked for some time). As far as I know, Coinomi does not support staking.

Packages for Fedora 25 and 24 containing the 1.2.3 version have been released.

HolyTransaction web wallet is closing at the end of the month.

Ryan Kennedy has been sentenced for 11 years due to three “rapes”. What about the Mintpal case?

There is also an IRC channel (#blackcoin on Freenode).

On average every 64 seconds a new block is created which yields 1.5 BLK (the block creator also gets fees of any transactions included in that block). The probability of creating a block is roughly equal to your stake weight (the number of confirmed blackcoins you owe which are currently not staking) divided by the presumed total number of online, non-staking blackcoins (which is shown in the graphical wallet). You can calculate your expected number of created blocks/blackcoins and compare it to the cost of keeping BlackCoin wallet online.

Yes, about 1.9 GB currently.

The packages were built mainly using the official RPM creation howto, somewhat referencing spec of Bitcoin packages, though they are much simpler (in particular, SELinux is not involved). I’ve done the packages for BlackCoin to support it and because I use them myself, but I’m not a RPM packaging expert and will probably not be interested in packaging other cryptocurrencies.

I’ve created BlackCoin RPM packages for Fedora 23 and 24. BlackCoin is maybe the first cryptocurrency to have packages for the just-released Fedora 24, as even the Bitcoin repository doesn’t support it yet.

The processor can possibly be extended to support arbitrary payments, including coffee payments, if there is a demand for that. Meanwhile it allows selling various forms of digital content without registration, sometimes in an unprecedented way (blog posts, ebooks, movies, photos, music and any other files). The biggest problem is maybe not the alleged lack of technical services for BlackCoin, but the low number of non-technical traffic creators: merchants, artists and service providers.

I’ve made a comparison of the number of active nodes relative to market capitalization for some popular, Bitcoin-descendant cryptocurrencies. BlackCoin is a clear winner.
