Which key differences between the Bitcoin and Ethereum blockchains must investigators consider when investigating flows of funds on each respective chain? (Select Two.)

Show Suggested Answer Hide Answer
Suggested Answer: B, D

Bitcoin and Ethereum have fundamental differences important to investigators:

Variety of applications, assets, and networks (B): Ethereum supports diverse decentralized applications (dApps), multiple tokens (ERC-20, ERC-721), and various networks, complicating transaction tracing compared to Bitcoin's primary use as a cryptocurrency.

Ledger model (D): Ethereum uses an account-based ledger model, while Bitcoin uses a UTXO (unspent transaction output) model, affecting how transactions are recorded and analyzed.

Transaction cost (A) and address length (C) differ but are less relevant for fund flow investigations.

Okay, I think I've got it. The transaction cost and the ledger model are the two key differences that investigators would need to consider. The way transactions are processed and validated is quite different between the two blockchains.

I'm a bit confused on this one. I know there are some fundamental technical differences, but I'm not sure which two are the most important for this investigation. I'll need to revisit the blockchain concepts we covered in class.

I've got this! The variety of applications and the address length are the two key differences I would focus on. Ethereum's smart contracts enable a much wider range of use cases compared to Bitcoin's more limited functionality.

Okay, let's see. Transaction cost and ledger model seem like obvious differences to consider. But I'm not sure about the other options - I'll have to review my notes on the technical differences between the two blockchains.

I think the ledger model is crucial since Bitcoin and Ethereum operate differently, but I’m torn between that and transaction costs for the second choice.

I feel like address length might be a trick option here. I vaguely recall it being different, but I can't remember if it's significant for investigations.

I remember studying the variety of applications on Ethereum compared to Bitcoin, so I feel confident about that one. The other option is a bit fuzzy for me though.
