Just a trivial note on Iota and its features.

Basically there are three features in Iota, such as:

- There is no mining ( = Pow)
- No transaction fees are required.
- DAG(Directed Acyclic Graph) = Blockless
- Designed for low power devices such as IoT

They use the logic “Tangle“, in which there are no blocks. (blockless blockchain) 
Each transactions has the hash of previous
transaction, and these are not connected by 1:1 but randomly. (1:n)
Plus, these 1:n connection can have significance attribute, such as 1: (1/3)(1/3)(2/3).
This significance is for the random walk, of which each transaction vector refers to the
next transaction. Unweighted randomwalk sets each next transaction’s probability equally,
such as: 1/3, 1/3, 1/3. If Weighted randomwalk used, then any of the destination can have
better contingency than the others.

Each transaction has to approve 1~ previous transactions in order to be validated.
