Building a blockchain app

Steps

Store transactions into blocks
Add digital fingerprints to the blocks
Chain the Blocks
- The hash of that previous block would change.
- This will lead to a mismatch with the previous_hash field in the next block.
- Since the input data to compute the hash of any block also consists of the previous_hash field, the hash of the next block will also change.
Implement a proof of work algorithm
Add blocks to the chain
- The data has not been tampered with (the proof of work provided is correct).
- The order of transactions is preserved (the previous_hash field of the block to be added points to the hash of the latest block in our chain).
- Mining
Create interfaces - i.e. RESTful API
Establish consensus and decentralization
- Asking the remote node to add a new peer to its list of known peers.
- Initializing the blockchain of the new node with that of the remote node.
- Resyncing the blockchain with the network if the node goes off-grid.
- Implement a consensus algorithm to agree on the longest valid chain
