> Key: MAHOUT-2142
> URL: https://issues.apache.org/jira/browse/MAHOUT-2142
> Project: Mahout
> Issue Type: Epic
> Reporter: Andrew Musselman
> Assignee: Andrew Musselman
> Priority: Major
>
> *About*
> Discussion and planning epic for adding blockchain data sources and analytics
> use cases. Proposal is to provide a new data source, namely any number of
> ethereum-compatible ledgers, and pick a few compelling use cases to build out
> this year.
> We will add children to this epic for specific work items.
> *Example Use Cases*
> # Search-indexes of given ledgers
> # Computed similarity to other accounts on the same ledger based on activity
> history
> # Time-series analysis of gas (transaction) fees across multiple ledgers
> # Time-series analysis of transactions (overall # per week/month/year/custom
> period, by user account etc.) for a list of ledgers. (Comparative analysis of
> usage)
> # Max/Min range of transactions for different ledgers
>
> *How to Get Started*
> To explore ledger operations and data, get a copy of go-ethereum (geth:
> [https://geth.ethereum.org/docs/install-and-build/installing-geth]) and run
> it against a network to get all historical records. The Goerli test network's
> entire three years of data is only 32GB, so there are small enough data sets
> to play with, and the data files are stored on your local disk by default at
> ~/ethereum.
>
> There are libraries that interact live with any given ledger including Web3JS
> ([https://web3js.readthedocs.io/en/v1.5.2/]) and Web3.py
> ([https://web3py.readthedocs.io/en/stable/]), so reading out of ledgers is
> simple.
>
> Reading and indexing the actual data might mean writing custom parsers for
> Mahout and Lucene, and possibly getting into decompiling bytecode back into
> readable Solidity code, so there are pieces we would need to plan out.
