# Design Notes


## Initial design choices

- protocol/routing/network layer: websockets (multi nonblocking clients)
- server-side fileformat : yaml
- client-side fileformat : JSON

## Language choice:
  serverside: perl (or nodejs)
  clienside: javascript

## block chain structure

 minimally sized blocks :
  - segreated signature, timestamp, audit etc.
  - block: {address, previous, pow}


## observation ...


- revokable block if sign w/ a DH on txo and ECDSA on txi

-  txroot (merkle root can be global)

-  PoW is to slow down chainupdate to avois spam
-  consensus is on the longest length
-  /!\ maximal work is hackable 
 
-  sort of tx sequence can be done on node side
-  block chain can store tx out of order (FIFO style)
