Definitely B. Consistent address is safer for transactions.

Cecilia 6 months ago

A sounds confusing. Why change the address?

Glendora 6 months ago

Yeah, B makes sense. Nonce prevents replay attacks.

Shalon 6 months ago

I think B is correct. The address stays the same, right?

Raina 6 months ago

Just learned about replay attacks, this is interesting!

Malinda 7 months ago

Totally agree with B, nonce is key for security!

Joseph 7 months ago

Wait, are you sure about that? Sounds off.

Weldon 7 months ago

I thought they changed addresses too, but B makes sense.

Cassi 7 months ago

B is correct, they keep the same address.

Nonces, addresses, blockchain - it's all Greek to me! I'll just guess and hope for the best on this one.

Myong 7 months ago

Wait, so the address doesn't change, but the nonce does? I'm going to need to re-read that section of the study guide.

Ellsworth 8 months ago

I'm pretty sure the address stays the same, but the nonce is what changes to prevent replay attacks. Gotta love those blockchain technicalities!

Felicia 8 months ago

Hmm, I thought the nonce was just a number that gets incremented with each transaction to prevent duplicates. This blockchain stuff can get pretty confusing!

Skye 8 months ago

The nonce is definitely the key to avoiding replay attacks, but I'm not sure if it's the address that changes or just the nonce itself.

Martina 9 months ago

I might be confused, but I thought EoAs change their address with every transaction. Is that really how it works?

Rocco 9 months ago

I practiced a similar question, and I believe the nonce is just a counter that helps maintain the integrity of transactions.

Valentin 9 months ago

I'm not entirely sure, but I remember something about nonces being important for transaction security.

Maybelle 9 months ago

I think EoAs keep their address the same, but the nonce changes with each transaction to prevent replay attacks.

Lauran 9 months ago

Ah, I see now. The address doesn't change, but the nonce is used to prevent replay attacks by incrementing with each transaction. Good to know for the test.

Lavonna 9 months ago

I've got this one! The address stays the same, but the nonce goes up with each transaction to stop replay attacks. Gotta remember that for the exam.

Brittni 10 months ago

Wait, I'm a bit confused. Does the address change or does the nonce just get incremented? I need to make sure I have this concept clear before the exam.

Augustine 10 months ago

Okay, so the nonce is increased with each transaction to prevent replay attacks, but the address itself doesn't change, right? I think I understand this one.

Gilma 10 months ago

Hmm, I think the nonce is used to prevent replay attacks, but I'm not sure if the address changes every time. I'll need to review that part.

Exactly! The address remains constant for EoAs.

Reena 4 months ago

↳ replying to Gilma

Yeah, it’s all about preventing those replay attacks.

I believe the address stays the same. The nonce just increases.
