Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Golden Star Casino Full Review

Payment processing has always been the biggest strain on the online gambling industry. Changing regulatory environments have sent casinos into a tailspin when they find out their main source of deposits is suddenly not available to them. In other cases, when an online casino finds a company willing to take them on as a client, the rates they are charged are as close to robbery as can be; this ends up cutting margins down to a bare minimum, making running an online casino less of an enticing career move.
The introduction of crypto-currency over the last few years has shown some signs of promise in the online gaming space. As the general public gets more accustomed to the idea of Bitcoin and its uses, we will see it adopted across more traditional purchasing. The gaming industry has adopted the technology from the start, with several Bitcoin-only sites popping up in 2013 and beyond. Recently, many providers have added cryptocurrency to their traditional payment methods, offering special bonuses for players to use the option.
Golden Star Casino is one of the true hybrid casinos when it comes to payments. As you will see in the review, the casino has integrated Bitcoin into all facets of their operations, from games to payments to promotions. This is a great way for players who aren’t familiar with the product to be able to give it a try without committing to a Bitcoin-only site.

About Golden Star Casino

Golden Star Casino is owned and operated by Jubise International N.V. Casinos, a Curacao based company. Established in 2012, the company also has a gaming license from the Curacao Gaming Authority. This license isn’t exactly rock-solid for players; the country tends to turn a blind eye to company behavior until it is too late. With the license, however, Jubise is able to attract the payment processors and software vendors it needs to provide you with a positive gaming experience at their site.

Who Can Play at Golden Star Casino?

Even though the company is licensed in Curacao, which would clearly give the impression that they would take players from the U.S., Golden Star doesn’t allow Americans to deposit or gamble. Well, actually… there is a way, but you need to be aware of what you are getting into. It seems that U.S. players who use Bitcoin to deposit can actually create real money accounts and play at the tables. However, there have been several instances of players trying to withdraw their funds which, once it was determined they were in the U.S., had those funds confiscated and accounts closed. It is hard to say if you can withdraw right into your Bitcoin account without it being detected, but for the time being, I do not advise you try this from the States unless you are willing to take the risk that your deposit may be taken away from you.
As for other restricted countries, here is the list:
  • United Kingdom
  • Spain
  • United States
Also, please bear in mind that certain software suppliers restrict what countries are allowed to access their games. As a result, you may find some of the games written about in this review are not actually available in your country. The best thing to do is to create an account, and you will be able to see all the options for your casino play.

Software Suppliers

As mentioned, Golden Star has chosen to work with several software partners for their brand. This is excellent news for you; the company has chosen a broad spectrum of vendors including some of the most prestigious in the industry. You can find games from the following companies currently at Golden Star Casino:
  • Microgaming
  • Betsoft
  • Net Entertainment
  • iSoftBet
  • Endorphina
  • Ezugi
  • Amatic
  • SoftSwiss
  • Quickfire
  • Belatra
  • Pragmatic Play
The casino games at Golden Star are available in a no-download format, meaning you can play them instantly through your browser. Many of the games are also formatted to be able to be played on most mobile phones or tablets, allowing you to take your casino experience on the move with you no matter where you are.

The Good Stuff

Jackpots

I love a casino that not only has several progressive jackpots available for its players but one who isn’t shy about telling you who has won them. At Golden Star, you can select from over 20 different jackpot games, and if you look on their jackpots page, there is a scrolling bar of recent winners; no one like to see that a jackpot isn’t paying out. Give some of their jackpot games a go if you want to get a little something extra out of your slots experience.

Bitcoin Slots

This is an interesting option for players; there are slots in the casino lobby that are designed for Bitcoin-only play. Why would a casino do this? Well, with the fluctuating value of Bitcoin these days, players may not want to get hosed on exchange rates. Also, this is an excellent way to have players learn about Bitcoin by having to think regarding the cryptocurrency throughout their entire casino experience.
Satoshi’s Secret is the most popular Bitcoin game in the industry, and you can try it at Golden Star Casino for free if you like to get a feel for the slot machine.

The Bad Stuff

Complaints about Terms and Conditions

No one likes to see complaints about an online casino, and many times I can dismiss them as individuals who are just upset that they lost their money. However, there are recurring concerns about the changing Terms and Conditions at Golden Star Casino. The company denies that they have made any changes without letting their players know, and have taken a strong stance on that accusation. I will continue to monitor that situation; if I find it to be actually happening, then it will be a big strike against the casino.

Games limited by Country

I’ll add this to the Bad Stuff because I live in Canada, and as a result, I am not able to access some of the better games that Golden Star Casino has on their site. While I totally understand why the casino isn’t allowed to offer all their games to all their players, it would be beneficial to have this information laid out in a clear manner somewhere on their website. I would much rather know going in instead of reading a review like this only to find out a game I love is not available when I make my deposit.

Game Selection

As I mentioned, you will find over 900 games at Golden Star Casino. I am going to take a look at all the different categories in more detail for you now.

Slots

It isn’t surprising to hear that the majority of available games in the Golden Star Casino lobby are slots games – this goes for almost every casino in the industry, whether online or land-based. However, having the multiple providers allows this casino to provide you several different looks to their slots catalog. They range from the fantastic content of the Microgaming slots to the 3D slot games that made Betsoft famous.

Table Games

The table games options at Golden Star Casino are a bit underwhelming considering how many suppliers the company has partnered with. Now, I may be missing some of the table games because of where I am reviewing the site from; all accounts are that they aren’t using Microgaming or NetEnt for games outside North America.

Video Poker

Along the same theme, there aren’t as many video poker variants as I would like to see at Golden Star Casino. I know that I am in the minority when it comes to video poker; I like the game more than most people do. Still, an online casino should easily be able to offer as many games as they can. Maybe they will read this review and add some from their vendors; I know they are available!

Specialty Games

One area where Golden Star Casino has apparently spent some time in development is in the Specialty Games offering. Using their partners like Quickfire, the casino gives you many different types of games to play that are not like the typical table games and slots. Many of these games have worse chances of coming out a winner, but I always consider them to be a nice way to take a break from a long session at the Blackjack table.

Live Dealer

Golden Star Casino has selected Ezugi as their Live Dealer provider. While the studios and dealers used by Ezugi are quite nice, there isn’t much in the way of selection from a games perspective. You can play the following games via the Live Dealer function:
  • Bet on Numbers (Bingo variant)
  • Keno
  • Blackjack
  • Roulette

PROMOTIONS

The promotions at Golden Star are pretty bland overall. They are focused on the deposit bonuses as their primary form of attracting to you to their brand. Here is an overview of the bonuses currently available on the website:

First Deposit Bonus

  • 100% up to €100 or 100 mBTC + 100 FREE SPINS
Make your first deposit in Golden Star Casino and get up to €100 or 100 mBTC and 100 free spins in the Lucky Sweets slot

Second Deposit Bonus

  • 75% up to €100 or 100 mBTC
Keep having fun! Make your second deposit, and we will refill your balance up to €100 or 100 mBTC.

Third Deposit Bonus

  • 50% up to €100 or 100 mBTC
More and more bonuses for you! Get up to €100 or 100 mBTC on third deposit!
The company does have one ongoing bonus for players who play on the weekend. They have a “Have A Nice Weekend” recurring bonus of 50% up to $50 or 50 mBTC.
Overall, it is pretty disappointing to see no leaderboard or jackpot promotions, especially given how many games they could use for these types of offers.

Tournaments

Golden Star Casino does have a large selection of tournaments running on a daily and weekly basis. For someone who gets bored with slots play pretty quickly, I enjoy the tournament concept; if I go on a long run, I can make some additional cash, and it is the only way I actually see any other screen names while I am at the casino.

Banking

As I have discussed many times in this review, the company seems to be very focused on making you a Bitcoin user, offering special games and bonuses for players who use the cryptocurrency. Golden Star does also have traditional payment methods available to its players; of course, each will be restricted by what countries are available. The most up-to-date payment methods for your country will be listed in the cashier section of the lobby after you login to your account.

Deposit Methods

  • MasterCard
  • Neteller
  • Visa
  • iDEAL
  • Sofortuberwaisung
  • QIWI
  • Trustly
  • Skrill
  • Yandex Money
  • Sberbank Online
  • Cubits
  • Comepay
  • Mobile Commerce

Withdrawal Methods

  • Bank Wire Transfer
  • Neteller
  • Visa
  • iDEAL
  • QIWI
  • Skrill
  • Trustly
  • Yandex Money
  • Cubits
  • Comepay
  • Evroset
  • Mobile Commerce
  • Sberbank

Comp/VIP Program

Golden Star Casino does offer its players a hybrid Comp/VIP program. In essence, this is a comp program that has tiers to it, giving you more enticing conversion rates for your comp points. While I am a big fan of casinos that give you comp points that you can cash in for real money, I am disappointed that there isn’t more to the VIP part of the program. I am hopeful that there is a more individual program that they just don’t advertise.
Here are the levels of the system and what conversion rates come with each level.
  • New Star – (0-149 CP) – no exchange
  • Bronze – (150-999 CP) – 14:1 Exchange
  • Silver – (1000-4999 CP) – 13:1 Exchange
  • Golden – (5000-14,999 CP) – 12:1 Exchange
  • Platinum – (15,000-29,999 CP) – 11:1 Exchange
  • Diamond – (30,000 CP) – 10:1 Exchange

Customer Service

Customer Service at Golden Star is available three ways: a web form on the Support page of their website, email or Live Chat. There is no phone number to reach the casino at this point; the only way to get a hold of them in real time is via the Live Chat function.

Technical: Upcoming Lightning Network Improvement: JIT-Routing

Bitcoin up? Down? Sideways? Who cares? Lightning Network is going LIVE and that's all that MATTERS!
Last time I talked about a bunch of upcoming Lightning Network improvements. They weren't complete, because there are a big bunch of them being worked on (or mostly just being debated, most devs are fighting bugs and adding boring little features like adding options for various timeouts in communicating with bitcoind and getting their impls out of beta / alpha and etc etc).
One thing I'd forgotten about was JIT Routing, which renepickhardt reminded me about. JIT Routing is actually a potentially-viable alternative to multipart payments / AMP, and in particular does not require a BOLT spec update, though does require that most nodes on the network implement it (unlike multipart, which requires only that the payer and payee support it).
renepickhardt introduced the idea here: https://lists.linuxfoundation.org/pipermail/lightning-dev/2019-March/001891.html
I feel this idea is underappreciated --- AMP gets all the press --- so it deserves its own unique Reddit post!

JIT-Routing

Rerouting payments by rebalancing just in time to service forwarding requests!

Background

Now one thing about multipart payments --- or even just current, non-multipart payments --- is that the payer is mostly just guessing what channels are viable to route through.
In the current scheme where payments cannot be split up, payers just do some payment through a route, then if that fails, tries another route, etc etc until it gets paid.
For multipart payments, it's not clear what algorithm to implement, actually. If some route fails, maybe it could work with a lower payment going through it, or maybe not; who knows?
The remote node that is sending the failure knows, but it can't tell the payer: for all it knows, the "payer" is really a spy node that's trying to trace how much each node owns (for example, as viable targets for the more sophisticated $5 wrench attacks). So all the remote node can safely say is "channel hazy, try again later" (temporary_channel_failure in BOLT terms) which could mean anything from not having capacity to the other endpoint being disconnected to the channel being overloaded with in-flight HTLCs to the node just being lazy today. It can't say "oh you can only route up to XX millisatoshi in that direction right now" because that immediately leaks how much money it and its counterparty owns in that channel, i.e. a minimum on how much a $5 wrench can extract from both nodes.
So since routing is source-based (so that the payer has maximum privacy and able to get around attempts at censorship), the source has to figure out how to get its payment to the destination. But the same principle of privacy-by-default means that the source can't get information about the capacities of the channels it's trying to route through, because the intermediate nodes sure as hell ain't gonna tell.
Now the insight in JIT Routing is that the forwarding node has the knowledge of the current channel liquidities of all channels it has. And rather than leaving the details of every routing attempt to the source payer, the forwarding node can instead make local routing decisions based on its knowledge of local channel state.

Idea

Yep. That's all of it. That, in a nutshell, is JIT-routing. It's probably more accurate to call it JIT-rebalancing.

Thank you for playing the quizchain. This block will have a slightly higher prize since it is a lucky number. Interesting coincidence that it is posted on a day with the unlucky number 13. The prize will be the cross sum of 37, which is 10 mbtc. Funding transaction below.
https://www.smartbit.com.au/tx/4e63d912321e10883730adcb1af660bca1a1dd0efe77bfedc2f0e6830ab82702
Question: I created a new word. Minmin. What does it mean?
Format: [solution] TOMI [TOMI]
Solution format is two words, with the first one starting with a capital letter, like this: "Word1 word2".
TOMI format is four words. Each has four letters. The first and last word differ by only one letter. Only the first word starts with a capital letter, like this: "Word1 word2 word3 word4". No words of dubious moral standing in this TOMI field. First three digits of MD5 hash are 394.
First digit of solution only MD5 hash is d.
First two digits of TOMI field only MD5 hash are 49. Interesting coincidence that these two are the last two of the whole MD5 hash read backwards. And d is the fourth letter in the alphabet.
Since the last block was on slow hint timing, I do this one with rapid-fire timing again. First hint after 30 minutes, second after a further 25 minutes, and so on, down to 5 minutes for the sixth one.
Have fun challenging this block and stay tuned for block 38, coming up tomorrow (Friday) 8 am Japanese time.
Update 1 (hint 1): No specific requests for first hint, so I will just go with what I had in mind. First word in TOMI field is a homonym related to Bitcoin.
Update 2: Players requested to step up the hint rapid fire to one each 5 minutes. Okay. Let's try this once.
Hint 2: How do you mine the quizchain?
Next one coming up 5 minutes from now.
Update 3:
Hint 3: The first word of the TOMI field is "Mine". It is a homonym, since it has the meaning to mine a chain or gold as well as "this is mine".
Posting these hints very fast increases the risks of making a simple mistake...
Hint4 coming up five minutes from now.
Update 4:
Hint 4: You all
Update 5:
Hint 5: Tomi field may be used as a slogan for the quizchain, just as "Satoshi without the consonants" is a catchphrase for my handle name.
Next (and last) hint five minutes from now.
Update 6:
Hint 6 (last one, after that you are on your own until further notice): First word of solution is "Quizchain"
Final update: While I was busy posting hints 5 and 6, the winner posted his solution, which he already found before hint 5. Solution was "Quizchain player" and TOMI field was "Mine with your mind".
The new word Minmin is a short way to say "Mindminer", which in turn means someone mining the quizchain in the way it is supposed to be mined (by thinking only). I liked the fact that "mind" and "mine" share the same first three letters.
Congrats to the winner of this slightly hectic round and thank you everyone for playing. I would be interested in feedback on the extremely rapid fire hint format. From my side I feel it is kind of stressful. On the other hand, it probably makes for a more exciting and thrilling experience.
Next block coming up tomorrow 8 am Japanese time, stay tuned.

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
Some great introductions for new users are My first bitcoin, Bitcoin explained and ELI5 Bitcoin. Also, the following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
Also have to give mention to Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series. Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute. Bitcoin statistics can be found here, here and here. Developer resources can be found here, here and here. Peer-reviewed research papers can be found here. Potential upcoming protocol improvements here. Scaling resources here. The number of times Bitcoin was declared dead by the media can be found here (LOL!), and of course Satoshi Nakamoto's whitepaper that started it all! :)
Key properties of bitcoin

Where can I buy bitcoins?

Bitcoin.org, BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Bank Transfer Credit / Debit card Cash
Gemini Bitstamp LocalBitcoins
Bitstamp Bitit Mycelium LocalTrader
BitFinex Cex.io LibertyX
Cex.io CoinMama WallofCoins
Xapo Spectrocoin BitcoinOTC
Kraken Luno BitQuick
itBit
HitBTC
Bitit
Bisq (decentralized)
Luno
Spectrocoin
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Android iOs Desktop
Samouari BreadWallet Electrum
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

[7 mbtc] Quizchain2 Block 52

Thank you for playing the quizchain. The last block was solved on sight, this one should be a bit more challenging, even though it does not need a TOMI field. It may well need a hint. If so, that hint will come up 24 hours from now.
Normal 7 mbtc block, funding transaction below.
https://www.smartbit.com.au/tx/649f2566b32f1db7783f8434c8a73c1e1f34a660c5b434f7b9419d6cf173c7e2
Question: Six words.
Format: [solution]
FIrst three digits of MP5 hash are 21b.
Have fun challenging this block and stay tuned for block 53 coming up tomorrow (Saturday) 5 pm Japanese time.
Update: Solved without hint. As winner explained in comments, solution was bat bat bot bit bet but. I noticed when I used the idea earlier that the "bit" of Bitcoin results in a word with all vowels except y, that "bat" is actually two words (the bat in Batman and the baseball bat), which is why I extended the concept to six words. The technical term for this is "homonym" meaning two words with different meaning but same spelling, so there is one homonym in those five words.
Congrats to the winner and thank you everyone for playing.

[Easy] [7 mbtc] Quizchain Block 37

Thank you for playing the quizchain. This block will attempt to make a quiz as simple as possible while using a brute force user block (BFUB).
The first thing to make it easy is to explain that BUFB is only there because the answer is easily brute forced without that protection. That means the solution string will be short (like a one letter solution like A in block 31) or a famous name like James Bond in block 27. That is a big hint for the answer. Go for the shortest solution that comes to mind with a BFUB block.
The second principle is to keep the BFUB string also as short as possible. Lets take block 31 as an example. Answer was A, BFUB was Before B."First letter in the alphabet" would be a much longer hint and therefore not adopted. I am not sure now if there is a shorter and more natural hint possible for the solution A. Please point it out in comments if you find one.
With these principles in place, let's try now to build the ultimate easy BFUB block.
This block is for 10 mbtc, since it has the number 7 in it (3 plus 7). Funding transaction below:
https://www.smartbit.com.au/tx/5654065b34c1652c0dee19034a7de7bf3999b43c9c20a3834f5834bf14928bea
Question: James Bond
Format: [solution] BFUB [BFUB string] [link] with exactly one space between them.
Link from Block 36:vXY
First two digits of hash: 3c
There are two things to test with this block. One is if the BFUB string is sufficiently complex to stop bots for a while. The other is if it is sufficiently easy to be solved by human players. Both goals are in conflict, which makes finding the right balance difficult. My aim is for this to be another easy block, even with the BFUB complexity of the format.
Anyway, let's find out what happens. Thanks for playing and good luck solving this block which I have tried to make as easy as possible under the format.
Update: Has survived more than an hour, so I am reasonable sure that the first test is a success. This is reasonably safe against brute force. Now for the second test. Can human players solve it? I will put a [Medium] flair on this post now. Good luck.
Update: This block has been solved now, congrats to the winner. And special thanks to him for the long report on how he solved the block, as well as the excellent suggestions on how to improve the format. The only point here to find the solution was to replace the 0 in 007 for o, since 0 is not allowed in Bitcoin addresses. From there on my BFUB hint was simply 0o, meaning replace 0 for o.
I am still not sure that this was a good BFUB. Its format was not announced from the start on and it actually is not something that comes to mind immediately. So while this may have succeeded in keeping bots from winning, we really don't know, since I have no idea if there is anyone running scripts to find solutions and if so, what resources they devote to getting one of the meager prizes in this chain.
Anyway, congrats again to the winner and another block solved. If I am not mistaken, only blocks 13 and 23 remain unsolved right now, and they are supposed to be impossible to solve right now. I also note that it has been only about a week since I posted the first block and I got so carried away with this that we are already at 38 blocks solved, close to half way to 77.
I would like to post the three next blocks 39 to 41 at around the same time and do a real quizchain. No announcing of links, which means you have to solve previous blocks to get a chance to solve 41. And no easy blocks like 38 in those. Let's see how the quizchain works under those conditions.
Stay tuned for the next three blocks and thanks for playing.

[Easy] [7 mbtc] Quizchain Block 31

Thank you for playing the quizchain. I just did the funding transaction for block 70, which will be for 77 mbtc, as all blocks until from 70 to 76 before the final 77 with 777.
This block will be easy for human players, I probably don't need to give any hints. It should still be reasonably difficult for brute force users, since I have a brute force user block (BFUB) in place now. The "FU" in "BFUB" certainly has no second meaning. This is just a technical term. I like it better than the BotFU I used in the last block because of the nice symmetry around the central FU theme.
It will be interesting to see if the bots can crack this easily. If so, knowing that is well worth the cost of using one block for this experiment.
Another 7 mbtc block, funding transaction below.
www.smartbit.com.au/tx/4431011443671bdc5cf43b83d408a205056904be5d8972173f4a0952186118c7
Previous block link digits: fTS
Question: BItcoin Second
Format: [solution] BFUB [BFUB] [link] with exactly one space between them and all words in answer capitalized.
First 2 digits of the hash are 26, so if you don't see those two digits, don't bother checking the BIP 39 tool. This does make it way easier to brute force many solutions, but also way easier for humans to check. I think humans go first, so I think the latter advantage is way more important than the former disadvantage.
Update: Not claimed after half an hour. Looks like this BFUB was enough to stop the bots at least for some time.
Update: Block has been solved, prize claimed.
Solution: A. (one capital letter).
Method: Look at first letter of Bitcoin, disregard others for B Second. A is first in alphabet, B second.
Finding BFUB: working from solution, develop hint. In this case Before B.
Discussion: Looking at the prize address, we see that this survived about 4 hours. Much longer than the other one letter blocks 25 and 26. Those were solved immediately. I find that this method is efficient to slow down bots. It makes solving for humans more difficult as a cost, though.
My challenge for block 37 will be to come up with a really easy one even under this format, or even better easy because of the format. I suspect that might be possible, but have no proof yet...

[77 mbtc] Quizchain2 Block 7

Thank you for playing the quizchain. This is a lucky number block and was a big 77 mbtc block in the first run. I keep it that way this time as well, but it will be the last really big one until 67, unless I manage to mess up again. Funding transaction here:
https://www.smartbit.com.au/tx/fe9bec614bc203f37ed5fd15236c75581bf012e83fc3f3ffdfaeac7858a2e8f9
In comments to the last block, people asked for stronger countermeasures against brute forcing. I am tempted to go into full overkill mode, but anything I do to make it harder for scripts also makes it harder for humans, so I will just go ahead with my original plan this time and see how it goes.
For this special lucky block, let's start a new altcoin. So I can start scamming large numbers of suckers into sending me their money in return for some worthless idiotic token. Will go to a billion dollar marketcap immediately in the coming Bitcoin bull market. I am sure it will be a great success.
The question is to find the name for that altcoin, starting out from the name "Bitcoin".
Format: [solution] TOMI [TOMI]
I do not need a link, since the entropy of this is sufficient to block outside brute forcing.
[solution] is capitalized like "Bitcoin", which means only first letter in capitals.
[Tomi] are three words in alphabetical order [word1 word2 word3], with one of them starting with a capital letter like the solution and the other two in all lower case.
First three digits of MD5 hash are df1.
First digit of solution only MD5 hash is 5.
First digit of TOMI field only MD5 hash is e.
Have fun solving this big prize block. I hope it is the last one for quite some time.

[7 mbtc] [7 mbtc] [11 mbtc] Quizchain blocks 45 to 47

Block 45
Thank you for playing the quizchain. This post will show all three blocks in this short chain. If you want to discuss, please reply to appropriate comment I made.
Having all discussion on one post makes it easier to follow. No need to switch between posts. Let's try this and see what happens.
I would also like you to try this idea in comments. If you do not solve the block, post one and only one solution you tried and have found not to work. Post your best shot. Do not repeat solutions other people already have reported. This is to help other players out, since they will avoid dead ends you already checked.
This one will have a BFUB field, but the question will determine it, since the answer does not require brute force protection. It will also use the last seven digits of the private key for block 44 as a link, to make it a bit harder to brute force. Someone succeeded in brute forcing the link in block 43, this change is in reaction to that.
Another 7 mbtc block. Funding transaction here
https://www.smartbit.com.au/tx/8514df7faec741d53faca908df5ccc855c760430759a2b5a12bf74ce00150f51
Question: Bitcoin Second
Format: [solution] BFUB Have fun with this block Da6Sn4J
Link for this is set to Da6Sn4J.
Solved pretty quickly also.
Someone in comments remarked that the same question was used before and had a different answer. I do not agree with that. This block has no BFUB field, which means that the solution can not be "A" as the last time I used this idea.
That is because this time the solution is shifting ALL letters in "Bitcoin" to the letter before in the alphabet, as opposed to shifing only the first in the other block. Really not that hard to come up with if you saw the other block and its solution.
Congrats to the winner and thank you for playing.
First two digits of hash: 66
Have fun solving this block so you can challenge block 46.
Block 46
Another 7 mbtc block, funding transaction here.
2900dfc636a5a9f8c3bbbc2f28dbd9c0fbc98b7d8c06c2e59de613c5f7dfa90a
Question:
Looking for another Bitcoin address, starting with 1A1. Not mentioned by me before here or elsewhere. I do NOT own this address.
Format: [solution] BFUB Think. Think harder. [link]
Find solution, which is the Bitcoin address I am looking for, leave BFUB unchanged and use last 7 digits of previous private key for link.
Note that [link] for this is last seven digits of private key of previous block, not last 3, to increase resistance against brute forcing.
Link not provided, you need to solve block 45 to challenge this one.
This one was solved rather fast. The prize claiming transaction was only one block after that of block 45. Survived only a couple of minutes longer than 45. You can learn from this quiz that the genesis block address starts with 1A1, if you did not already know that.
Congrats to the winner and thank you for playing.
First two digits of hash: 58
Block 47
This one is for 11 mbtc, since it is one of the special blocks ending in 7. Funding transaction below.
https://www.smartbit.com.au/tx/f0e7f3f0fa053d4c05354eab666e99a0e40a4475ed098b5473759ce93b41b92e
Question: Another difficult math problem. 1231
Format; [solution] BFUB [BFUB] [link]
BFUB will be four or less words, all of them lower case and seperated by one space, if there are two or more.
First two digits of hash: b9
That's it. Three blocks on one page. Let's see how that works. Have fun solving these blocks and thank you for playing.
Update: changed "BR the link" in "brute forcing the link" above, this change does not affect solution in any way.
Update: Last block in this series solved now. A couple of comments.
For one, the idea of three blocks in one Reddit post is not successful. It makes it harder for me to avoid mistakes. I have gone back to posting individual blocks.
This particular block survived for five days between confirmation of the funding transaction and claiming of prize. One interesting aspect of a Bitcoin quiz is that it comes with a time recording function built in. Anyone can look at the funding address and see exactly how long this block survived.
The solution was rather simple. Only one digit, the number 7, as the cross sum of the number posted in the question. One reason was because this was a block including 7. One other reason was that this time the Hoax was making people think this is again about the MATH hats (like in previous blocks) while it was actually exactly what the question said, though the part of it being "difficult" was another piece of misdirection.
Congrats to the winner and thanks for playing.

[7 mbtc] Quizchain2 Block 5

Thank you for playing the quizchain. The last block was solved fast. So I will choose the slightly more difficult way to use the idea for this block. It is a nice match to the block number. Again, this needs neither TOMI field nor link, since the solution has already enough entropy on its own. Makes it very unlikely that I screw up somewhere. Still going to double check, though.
Another normal 7 mbtc block. With the recent increase in bitcoin price, these 7 mbtc blocks become somewhat more valuable than in the first run. Good luck to everyone.
Funding transaction below.
https://www.smartbit.com.au/tx/0dcc393425a6cd5b5266a7275e08c98fbd6c14b9b9518eb8020c34c39a655e18
Question: Five words.
Format: [word1 word2 word3 word4 word5]
One space between words and no period at the end.
First three digits of MD5 hash: e7a
Have fun solving this slightly more challenging block. Another big block coming up for lucky 7 soon (except if there is a mistake in this one, in which case block 6 will be big as well).
Update: Solved, but prize not successfully claimed as of now.
I posted the funding transaction only about 10 minutes before the block, with the default fee my wallet suggested. Turns out the funding transaction is stuck without confirmations. Not sure how this will play out, but I will certainly make sure that the winner gets 7 mbtc one way or another.
Solution was "bat bot bit bet but". As winner posted in comments, a similar concept was tried in a block of the first run. I think it is fun to note that the "bit" in Bitcoin is a word with almost all vowels, with Y the only exception. Good job finding this solution so fast. Congrats to the winner and thank you to everyone for playing.
My Twitter poll on what time is best for players got a fairly distributed result this time, so basically I will rotate through the times offered as options there. This means that the next block 6 will be posted at 6 pm Japanese time today (Wednesday), which is a good match to the block number. Stay tuned.
Second update: Funding transaction and prize claiming transaction both confirmed now.

Thought experiment: what happens to Bitcoin market cap if mBTC is the base unit (1 mBTC = $13.08)?

I've recently been thinking that a lot of the price action has been driven by new market entrants feeling 'priced out' of BTC – meaning they feel that if they can't afford a 1 btc, why bother. That has driven a lot cheaper, less fundamentally promising (imo) coins to insane levels.
If exchanges moved to mBTC as the base unit, do you think Bitcoin market cap would explode and accelerate adoption? Or do you think this has nothing to do with it, people genuinely believe in the underlying tech of other coins.

[7 mbtc] [7 mbtc] [7 mbtc] Quizchain Blocks 48 to 50

UPDATE: change all TOMI below to BFUB (legacy format). I hashed with that and changed to TOMI in post at the last minute. Sorry for that mistake.
Block 48
Thank you for playing the quizchain. This block serves two purposes.
First and more importantly, I want to use this to warn players not to fall for a Nigerian scam based on this quizchain. Fortunately the prize money now is low and not many players are competing. Quiet and peaceful early times for this little experiment. But I will eventually post a 777 mbtc block, once I am confident the format works well and I am experienced enough to avoid mistakes. Some scammer might try to take advantage of that situation. There are giveaway scammers all over the place on Twitter.
So I wrote a little story based on one of the scams mentioned in the 1617 Book of Swindles. Is now at chapter one of the Wattpad story. There may be a hint for this block in this story, but this block really doesn't need any hints.
And the point here again: I will NEVER ask for money to flow in my direction. If someone asks you to send them money, that's not me. Don't fall for a type 20 scam.
Second, I want a nice and easy question to start this series. It will have a BFUB field (name changed to TOMI), but I will say what to put there in the question.
Past attempts to start easy have failed, like when I added a little twist to block 42 and saw people unable to solve it for days. I hope this one is really easy. Still very difficult for me to predict difficulty before I actually post something.
7 mbtc block, funding transaction here.
https://www.smartbit.com.au/tx/574c8c91192669b4fc76f199ee813ee8e6883c84bfee1513062ae4a60c7647c4
Question: Like in that story, you want to send me a bribe. But you want to use Bitcoin. What amount in mbtc do you send to what address?
Format: [solution] TOMI This one is really easy. No need to bribe anyone to get it. [link]
Format for the solution is [amount in mbtc] for example 0.7 mbtc and then a Bitcoin address. One space between amount and address.
TOMI means "Thinking Only Method" and is the same thing as the BFUB field, just with a different name that avoids the bad manners. I explain that name change at the Wattpad story a bit.
Link from previous block (still unsolved): P5fCnpv
Update: Block solved fast, as expected. Solution was 0.777 mbtc 1AndrewYangforPresident2o2ozm6Pzd. Only problem was that I hashed with old BFUB field name and then changed to new TOMI name. Another mistake that shows me it is way too early to risk posting a 777 mbtc block.
First three digits of MD5 hash: 944
Thank you for playing the quizchain and have fun solving this block.
Block 49
This is supposed to be another easy block. And another one where I tell you the TOMI field. Might be brute forced, but if so, that tells me something about the format.
7 mbtc block, funding transaction below.
https://www.smartbit.com.au/tx/b911b08d4cfd3f682faa48ce4cc6e2e694fbf7e1e616972630372b4867d1024d
Question: You are looking for three words. Those three words are all lowercase. And they must be in the correct order.
Format: [word1 word2 word3] TOMI Good luck with this block [link]
[link] is last 7 digits from previous block private key, not 3, to make it harder to brute force a link.
First three digits of MD5 hash: 3bc
Block 50
This one is a bit harder, uses the format to show that it works with multiple choice questions.
7 mbtc block, funding transaction below.
https://www.smartbit.com.au/tx/1873629ecccf23b2d2cdd30bc337c925f818e6bc0e5c8424f96d1216022c5102
Question: Multiple choice
a) blue
b) green
c) red
d) yellow
Format: [solution] TOMI [TOMI] [link]
Format for solution is only answer, leave out leading a). For example, if you think a) is the answer, write blue as solution, not a) blue.
TOMI format is [word1 word2 word3], with all words lower case.
[link] is again 7 last digits of previous private key.
FIrst three digits of MD5 hash: f7d
I posted all three blocks together again. Like in the last series, if you want to discuss, reply to appropriate comment below.

A proposition: ₥, the "mill," should be the currency symbol for mBTC.

This post outlines why ₥, the "mill," is the natural choice for the short representation of ฿0.001, and why its simplicity will make it much easier for us all to talk about mBTC.

Abstract and Executive Summary (TL;DR)

There is a serious use case for talking in terms of mBTC rather than BTC, since the price has continued to rise exponentially. Being able to talk in terms of mBTC means we can talk in units of currency that are more familiar to the average person in terms of purchasing power. However, the word "millibitcoin" is rather unwieldy, and it has no shorthand currency symbol. This proposal fixes all of those problems by proposing the use of 1₥, or one mill, to represent the denomination of ฿0.001. Furthermore, this proposal outlines a simple way to extend this notation to arbitrary SI/metric divisions of any unit of any currency, as in ฿75₥, Ł75₥, ฿1,000,000n̸, etc. Alternative stylizations of the mill are also provided for those who prefer alternate stylizations of the Bitcoin currency symbol instead of ฿.

The problem

The dollar has $ as its symbol. When we talk about 1/100ths of a dollar, we don't talk about cUSD or c$, but instead we have a different symbol ¢ for cents. So rather than being like "I found 75 cUSD (centidollars) in my pocket!" we can just say "I found 75¢ (cents) in my pocket."
Likewise, bitcoin has ฿ as its symbol (or Ƀ, or B⃦, or whatever). Rather than talk in units of ฿0.01, it's common for us to talk in units of ฿0.001, or 1 mBTC. However, mBTC currently has no established symbol, nor an established "short" name, so it's unwieldy to talk about. "This shirt costs 20 millibitcoins" isn't very attractive.

The solution

The natural choice is the symbol ₥, which is called the mill. It is the natural choice for the symbol for 1 mBTC because:
  1. The symbol ₥ already has Unicode support at U+20A5, and it is already called the mill.
  2. The term "mill" is superior to "millibitcoin" because it's one syllable and parallels the "cent."
  3. This symbol is not in widespread modern use to denote any major currency.
  4. Despite the obscurity of this symbol in modern times, the mill was at one point used historically to divide arbitrary currencies into units of 1/1000.
  5. Hence, it has an already-established general meaning when dealing with currencies, yet it isn't tied down to any specific established currency, and it's waiting for a currency that needs a division into 1/1000s to resurrect it - perfect for Bitcoin.

Conventions

The convention I propose for using ₥ is to parallel ¢ and put it immediately after the number:
Since it seems reasonable that other cryptocurrencies might follow suit, one can then prepend the currency symbol when context requires it:
Or you can put the currency name after, as follows:
I expect that the symbol ₥, by itself, will probably be associated with Bitcoin by "default," however.

Metric System Extensions

In the future, we may even find that 1₥ becomes rather large, and so we'll have to start talking about microbitcoins if that happens. We can apply the same basic pattern above by using the other SI prefixes instead, and putting a diagonal stroke over them. For now, we can apply the diagonal stroke to any standard unicode letter by following it with U+0338, as in: µ̸, n̸, p̷, etc, with short names just being the name of the prefix ("mics," "nans," etc). Some examples from the year 2200 (be sure you have good unicode support):
You'll note that this is backward-compatible with both the cent and the fact that the SI prefix for 100 is to have no prefix at all.

Variations

Some people have insisted that the single stroke through ฿ is a bad thing, and have insisted on a small horizontal stroke or a double vertical stroke instead, as in Ƀ or B⃦. We could insist on making these currency divisions have the same look and feel by using Unicode diacritics U+0335 and U+20EB. Examples:
Alternately, if you're feeling more minimalist and don't feel like stylizing things at all, you can skip the strokes entirely and go with ordinary letters:
This has the benefit of not requiring extra Unicode support, and being backward compatible with statements like "OMG, someone just did a market buy of ฿25K on Gox!"
EDIT: Added TheZombio's suggestion from here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
