Support for Altcoins based on Bitcoin

Bitcoin inspired numerous Altcoins that are based on the Bitcoin technology itself. The good news is that most of the Altcoins can directly be analyzed with HadoopCryptoLedger (on Hadoop, Flink, Hive and Spark), because the data structures are the same.

For example, by changing the MagicNumber in the Options, you can easily read Litecoin, Namecoin, Emercoin or Zcash data (see here).

Certain Altcoins, such as Namecoin, require that you can read blockchains supporting AuxPOW/Merged Mining (see also here). This support has been added in version 1.0.8. It needs to be explicitly activated (see here).

Note that Bitcoin Cash is supported as well without any change. However, due to the different size of the blocks of up to 8 MB you need to configure the option hadoopcryptoledger.bitcoinblockinputformat.maxblocksize to 8 * 1024 * 1024.

The default maxblocksize is since version 1.0.7 8 MB to cater for the Bitcoin standard segwit2x.

Finally, for some Altcoins, we offer certain additional utility functions (cf. Useful Utility functions). However, you can implement any utility function for any Altcoin in your Big Data application and you do not need special support for this.
