Antana

Antana was created by Anton and Ana of Melbourne,
Australia. The name is a combination of the creators
names. The idea behind Antana’s coins is unique, in that
they mark ‘difficulty changes’ in the Bitcoin network
which happen approximately every ten days. The back
of each coin contains a date, and ‘network statistics’
from that day are recorded on the coin. In addition
to recording something newsworthy going on in the
crypto-currency sphere at the time, four metrics are
recorded for perpetuity: hash rate, difficulty, block, and
total BTC. They are explained below:
Hash Rate refers to the processing power of the Bitcoin
network, calculated in ‘Thash/s’ (1 Thash/s or Th/s is
equivalent to one trillion calculations per second).
Difficulty refers to the relative maximum amount of
processing power that is needed to find the next block.
Block refers to a ‘confirmation’ on the network
which settles transactions. New blocks are created at
approximately 10 minute intervals. The number on the
coin refers to the block that was reached that day.
Total BTC refers to the total amount of Bitcoin that has
been mined into existence from Bitcoin’s launch to the
date on the coin.
Since all Antana coins are identical in composition, size,
and weight, they are all recorded in a single table. A total
of 21 coins have been released, perhaps to intentionally
refer to 21 million bitcoins which is the maximum
amount of BTC that can ever exist.
