Topic: BITCOINTALK unofficial quiz NOVEMBER Edition. (Read 386 times)

We've had some pretty nice answers to the quiz lately. However I will be updating the thread soon enough with the answers to all the quiz questions. I'll likely be doing that very close to the end of this week in preparation for next week's quiz edition. Do well to test yourself if you haven't and avoid copying external resources if you can't answer a question simply indicate by putting skip.

Feel free to suggest improvements for the contest in later editions as Time goes on to make the whole experience more interesting Thumbs up to those who have attempted so far and double thumbs up for those that have made suggestions in addition too for further improvement.

So unused Bitcoin block capacity is the reason average is still around 1.7MB despite Segwit increase adoption to legacy.

Okay I think I understand what you meant by Segwit not been separate from the traditional Blocksize.
Size is measured in weight and Segwit is 'lighter' than Legacy
So 4MB of Segwit is 1MB of legacy. Traditional limit wasn't changed
Segwit just made it possible to have 4MB in place of the 1MB because of it's 'lightness'

Segwit has better adoption since 2017 especially since the last bull market in 2020 and 2021 years. People still use Legacy but they are using Segwit more than past years, it's good adoption for Segwit and can help other Bitcoin users too by minimizing effects on Bitcoin mempools.

Segwit spending transactions, Segwit spending payments, and payments and blocksize charts can elaborate Segwit adoption and unused Bitcoin block capacity. Many Bitcoin blocks are not full in capacity.

https://transactionfee.info/charts/payments-spending-segwit/
https://transactionfee.info/charts/payments-and-blocksize/

This chart for Legacy to SegWit inputs transition is interesting. It shows that Legacy usages are dying and Segwit usages are increasing a lot and recently it is about 97% inputs are Segwit, 3% inputs are Legacy.
https://transactionfee.info/charts/transactions-segwit-transition/

SegWit is not something separate to not be considered. It is part of the protocol and witnesses are part of transactions so they are part of the blocks and are contributing to the size.

Back in 2017 with the SegWit soft-fork the capacity limit (1 MB block size) was changed from being base on size to be based on weight (4 MB block weight). To put simply bitcoin blocks have been able to be bigger than 1 MB; and the more SegWit transactions with bigger witnesses these blocks include, the bigger their raw byte is going to be.
You can see big blocks here with 4 MB raw byte size if you sort like this:
https://blockchair.com/bitcoin/blocks?s=size(desc)#f=id,hash,transaction_count,size,time

But because not all transactions have witness (people still use legacy) and not all witnesses are big, the block size is usually about 1.6-1.7 MB.

Let me put in my little effort as a first trial whether i could get some right or not, the questions could be teasing as well as being educative and informative, thanks for the initiative.

I couldn't answer question 4


The year was 2017


Appriximately 1 megabyte


Its not been precise to be 144, is was approximated


Because we dont know if he is a single entity or group and this remain unknown


4 maybe


year 2015


funny


50 as at then, not sure of now.


holder knew it could turned to something magnanimous one day


2009


i dont think so


false


true


true

Usually it is about 1.7 MB but sometimes the protocol abusers spam the chain with arbitrary data injected in the witness parts of transactions and increase that.

[/quote] I don't really get this part
When I checked before I saw a site https://ycharts.com/indicators/bitcoin_average_block_size that stated 1.706Mb and felt it was a mistake
Since I'm aware of the 1Mb limit.
Is Segwit considered among the average?

1. Segwit protocol implemented August 2017
2. The average size in Bitcoin blockchain technology is 1 megabyte.
3. 144 blocks are minned per day , true
4. No , remains same as before
5. PSEUDENONYMOUS ENTITY means no proof.
6. 2, 1st 2022, 2nd 2024
7. Ethereum launched at 30 July 2015
8. Pass
9. 50
10. Maybe Satoshi forgot to send it.
11. No Idea
12. Mia knows that
13. False, Sigwit word mistake, right segwit
14. True, bitcoin volatile currency
15. I don't know

2017

~0.8mb

Not exactly 144, so false.

No, simple as that.

Because nobody knows his true identity, whether it's one person or a group.

2

Who cares? We are in BTCT!



50+

I'm not Satoshi to know.

Once again, who cares? We are in BTCT!

No. Mia can only wish and wait.

False.

True.

True.

Thank you for this quiz, it was fun! Expecting more like that...

This is nice one but since you are a developer indicated in your of your comments. You can make it more mature way like the way Icopress did in January 14, 2022 in the thread https://bitcointalksearch.org/topic/quiz-2023-history-of-bitcoin-and-bitcointalk-5381367 and in this way https://app.involve.me/bitcointalk/test-your-bitcointalk-know-how so that it is only the results are displayed here. Though everyone has their method of administering a test or a quiz but using a sub survey site to do it will look neat. I believed you can think to do that in your next quiz. All for fun.

The main goal was actually to fix the transaction malleability while also increasing the capacity.
SegWit was "implemented" a couple of years before its "activation" (around 2015 IIRC) and the implementation was improved until it was activated in 2017.

Usually it is about 1.7 MB but sometimes the protocol abusers spam the chain with arbitrary data injected in the witness parts of transactions and increase that.

Nothing in PoW which is based on chance, is exact

The number of blocks found per day would be doubled until we reach the next difficulty adjustment target which is 2016 blocks (about 2 weeks under normal circumstances).

Because Satoshi was an entity that was pseudenonymous LOL

I don't really follow that!

Who cares

Shitcoins are always a burden for Bitcoin anyways

0.18225651BTC

You should ask Satoshi why he never touched any of his coins including what is locked behind the Genesis block's key.

Who cares

I find this question a bit weird RBF is for transactions where you are the spender. Whether the parent is confirmed or not you can spend it and mark your tx as RBF. CPFP can be used for unconfirmed transactions regardless of the RBF.

False!
But it can be considering Genesis output is not an address to begin with, it is a P2PK output (without address) and like those who made a P2PKH address from the public key and sent coins to it, one can create a P2WPKH (and any other type) from that pubkey and send coins to it too...

True!

True!

Personal opinion , I think most of these answers can be gotten via web and not to mention
Individuals would just copy answers similar across the thread or from reputable members.

1. August 2017 and it was actived Aug 24th 2017

2. It was 1mb before SEGWIT, then is now 4mb

3. Yes because 24 hours divided by 10 minutes per block gives 144

4. No because the system called " difficulty adjustment" will have to be applied.

5. Because he's anonymous, his identify is hidden and no one knows if he's a group or one person.

6. Guess 4 but I have only witness one

7. No ideal

8. Lol. No I didn't

9. 50 Bitcoin which was January 3rd 2009 if I'm correct.

10. For it to serve as symbol representing the first block or a reward for mining the first block.

11. No idea

12. Skip

13. Skip

14. Skip

15. Skip

• 2017.
• The average size of a block is the blockchain size divided by all the total number of blocks, which will get to something around 0.8 MB, I think.
• No. Approximately 144.
• Assuming you turn these machines on, then yes, it would double the number of blocks mined per day, until the next difficulty adjustment.
• I guess because there is no man named like that?
• No idea. Best guess: 2.
• Nope.
• Exactly.
• In the address? 50.18220191.
• Again, of the address? Only Satoshi knows. But, if you're asking of the public key which received the genesis block reward, then they are unspendable.
• No idea what's that.
• No.
• False. Plot twist: There is no genesis address! 
• N/A. Something is volatile in comparison to something else, just as something is stable in comparison to something else.
• True.

• 1. 2017, was suggested by a Piete wullie in 2015 and was later implemented in 2017
  

• 2. 0.7928MB
  
  

• 3. Its close, but not exact, 144 blocks is an average, but can vary slightly (lower or higher) but on the average, that number seems more reliable
  
  

• 4. No, the hash rates can increase temporarily and more blocks mined, but the network difficulty would adjust it to maintain the average of 144 blocks per day
  
  

• 5. The name being associated to a person or a group remains unknown and their actual Identities remains a mystery.
  
  
  

• 6. maybe 2 or 3
  
  
• 7. SKIP
  
  

• 8. YES, before you straightened me up
  
  
• 9. 50 bitcoins
  

• 10. It could not be spent because its non-existent in the UTXO database
  

• 11. SKIP again
  

• 12. NO, only Satoshi as the sender can do RBF, Mia can only do CPFP
  

• 13. FALSE
  
  

• 14. TRUE
  
  

• 15. TRUE
  
  

Mia Chloe Bro, What more can be answered here? I saw some people answered earlier. So if someone else knows the answer to that question, he also needs to answer it?

I think since you gave it in quiz form you should have given some rules regulation.  For example:

 1.  Posts may not be edited or deleted.
 2.  You can answer as many as you want.
 3.  After you post, you cann't post a second time unless someone else is replying.
 4.  If no one can give a correct answer then I will.
 5.  One's correctly answered question cannot be posted a second time.

I think it should be like this. But it is not compulsory for you can do whatever you like.  But it is better to maintain quiz topics like this. Thank you.

1 i believe the segwit protocol was implemented between 2017/2018

2 average size of a block is 1mb

3 yes, that is true
true

4. I don't know this one

5 because he is unknown (easy)

6 I don't know, I just joined

7 2015

8 😅😅

9 I think between the rang of 50-60 I can't remember the actual number

10 due to the way it was coded, making It unspendable

11 2007

12 yes of course

13 false (I think)

14 true

15 true

1. The protocol was first developed in 2015 but was activated on 24th August 2017 by Pieter Wuille; it is more for transaction malleability than for scalability,

2. 1MB is the average size but since the SegWit fork where transaction are base on weight units it is 4,000,000 weight unit (assume 4MB, if all transactions are in SegWit)

3. No the 144 blocks are the average to be mined a day base on the average 10 minutes to mine a block but this does varies and can be more or less due to the mining rate (difficulty) of the hardwares which are sometimes more or less than 10 minute

4. It will be base on the hashrate if it increases the block will be mine faster but doubling its doesn’t necessarily mean it will function twice. This is also corrected after 14 days as the term called difficulty adjustment

7. 30 July 2015

9. 50 bitcoins

10. Maybe because it was said that the coin base transaction wasn’t added to the global transaction database as I read and as such all nodes will reject.

12.  No Mia can only do a CPFP because he is the recipient. Only the sender can do a RBF

13. False

14. True

14. True


All the answers are on the forum

Perhaps I'm not perfect but from a quick Google search and with my little forum knowledge combine here is my answer.

1. It was implemented in the year 2017 August by Peter wuilier but he first introduced it in a conference in 2015.

2. The average size of a Bitcoin block is approximately 2-4 MB, since the introduction of SegWit in 2017 but it can vary depending on the transactions included.

3. An average of one block is mined every 10 minutes, so it's probably true that 144 blocks are mined every 24hrs.

4. The Bitcoin protocol's difficulty adjustment mechanism makes it difficult for blocks mines per day to be doubled but it could increase based on my knowledge which could be wrong.

5. because his true identity has remain anonymous ever since.

6. I have been only here for 2 years, and only two Halloween contest have I witnessed. I don't know the exact number that has been hosted. ..... still making research.

7. Skip

8. Skip again.

9. The Genesis Address has nothing less than 50BTC in it.

10. The coins in the Genesis Address were not spent because Satoshi Nakamoto never wanted them to be spent based on my own gesture or but folks have other opinions about it.

11. The Paradigmic event of Bitcoin took place in 2009.

12. No. Mia is not the sender, only the sender can do the Replace By Fee (RBF) action without CPFP.


13. False. It's a Legacy address

14. True. Bitcoin is a volatile currency.

15. False. You can't receive your change address since it's created for leftover funds in your wallet.
