Example 0: Getting started / installation Example 1: Getting Status from the Node Example 2: Eth Balances for Three Accounts Example 3: Eth Balances over Time Example 4: Token Balances over Time Example 5: Monthly Bank Statements Example 6: For Every Chain Example 7: 1000 times more data in the same amount of time Example 8: Remote RPC vs. Local RPC vs. Cached Local Data
Example 1: Getting Started
This will just show the meta data and help the user learn how to build their own examples.
Example 2: Eth Balances for Three Accounts
This will query for balance of three accounts (using name to find Vitalik for example, a .eth, and a hard coded address).
Example 3: Eth Balances over Time
Using When, find some blocks per date. Show balance histories per date.
Example 4: Token Balances over Time
Find a token, find some dates, get token balances over time.
Example 5: Monthly Bank Statements
Use chifra export --accounting --balances over time.
Example 7: 1000 times more data in the same amount of time
Start by showing time chifra blocks 1000000-2000000:10000. This takes about X seconds. No cache -- querying the node.
Next add --hashes to the command. Takes about 1/4 the time. Still queries the node. No cache. But faster. Points out that TrueBlocks is flexibile.
Next add --cache. Same amount of time (perhaps even slower because still querying node but now writing the to cache.
Next rerun previous command. Out of cache. Takes X/500 seconds.
Next change :10000 to :100 (100 times more records). Still 5 times faster than original.
Next change to :10 (1000 more records than original). Only twice as slow.
500 times faster data.
Allows for much deeper analysis.
Allows for iteration.
Can go back and forth between 10000 (for exploration) and 10 (for detail work).
Better Data Faster
Example 8: Remote RPC vs. Local RPC vs. Cached Local Data
Follow on to 7. Starts with cached data - super fast.
Shows --decache (allows for cleanup)
Show slowdown of reading from local node instead of cache.
Switch to remote node.
Expensive. Slow as shit. Not private.
Better Data Faster.
