Questions tagged [eos]

EOS tag refers to the EOS.IO blockchain technology - see https://eos.io/ and also https://eosio.stackexchange.com/

The EOS.IO Software is open source blockchain infrastructure software.

It's found on GitHub here: https://github.com/EOSIO/eos

There is also a stackexchange site here: https://eosio.stackexchange.com/

Questions tagged with 'eos' or 'eos.io' will typically refer to the blockchain software, and to questions about configuring it, forking it, installing it, running it, or writing smart contracts on it.

Of the two, 'eos.io' would be better for two reasons:

  1. 'eos' already has other meanings, and searching on 'eos' brings up 4,700 false positives;
  2. 'eos.io' is the actual official name of the software as of December 2017

Therefore I recommend this tag be renamed 'eos.io' and an 'eos' tag be aliased to it.
