Research on storage considerations #10

Blockchain state storage ?
Sharding ?
What else could be used to save the blockchain and its state and blocks

RazvanBerbece commented 2 years ago

Blockchain data can be stored locally and it differs in size based on the type of Wallet client someone uses.

Bitcoin uses different types of clients / nodes :

Full Node (has the entire blockchain stored locally)
Light Node (user-focused, has only some blockchain data stored locally, mostly data used for transactions)
Miner Node (miner-focused, has some of the blockchain stored locally, mostly used for mining / finding nonces)

Implementing Blockchain state storage (full detail storage, light detail storage - for lightweight nodes) in json files. JSON files will be distributed between peers and synced. The JSON file data will then be deserialised into the ZRD client in a Blockchain object.

1/2 Done

Blockchain state sharing implemented successfully. States can be sent via TCP connections, serialized, deserialized, etc.

Next Steps

Develop a Lightweight Blockchain model used for lightweight nodes to be able to do offline transactions. This lightweight model would be a full model without :

Dynamic Configs (difficulty, TTM, reward, etc.)
A Blockchain Wallet (TBC)
Full Block data
