# Blockchain Infraesctructure document with 2 proposals

###### tags: `blockchain` `citeo`

- Private Network
    - Recomended at least 6 nodes
        - Hardware
            - 4 cores
            - 16 GB RAM
            - 500 GB 
        - 4 Regular FullNodes
        - 2 Validators 
    - CONS 
        - Work of at least 6 hours/week maintaining the private network
        - [Price of one server](https://www.digitalocean.com/pricing/):  ![](https://i.imgur.com/AHJlIKz.png) 
        - \$80/month x 6 nodes = 480$/month, it could be done with 2 nodes, but the recommended is at least 6 nodes 
        - Need to instantiate a new explorer like [etherscan](https://etherscan.io/) if is needed to see the transactions in the network
    - PROS 
        - Private network can have his data all private, between the 6 nodes, even the hash of an traceable can be private and not be seen for the outside world
        - We can generate our onw ethereum coin

- Use ethereum public network
    - Recomended to have a node server to send our onw transactions to the public network
        - Hardware
            - 4 cores
            - 16 GB RAM
            - 500 GB 
    - CONS
        - Work of at least 2 hours/week maintaining the node
        - [Price of one server](https://www.digitalocean.com/pricing/):  ![](https://i.imgur.com/AHJlIKz.png) 
        - $80/month x 1 node 
        - Pays ethereum coin for each smartcontract use 



- Smartcontract costs
- To Deploy contract transaction cost 656530 + 452286 execution cost = 1108816 gas

- deploy is just one time
- 0.0521144 ETH 

- Transaction add new traceable data costs, so this will run at least 5x for each traceable tracked
- To run the function addTraceableState: transaction costs 140604 + 114148 execution cost = 254752

![](https://i.imgur.com/3qbtfXf.png)
- Run 5x times for each traceable tracked
- 0.0119733 ETH x 5 states = 0,0598665 ETH per traceable tracked = 418,51 R\$

<!-- - 10 traceables a day x 0,0598665 ETH = 0,598665 ETH
- 30 day month x 0,598665 ETH = 17,95995 -->
