Realtime Bitcoin
- em3rgent0rdr 9y agoBeautiful. I think text size should always be proportional to log(transaction size) for better visual processing. I notice once $650,000 which was indeed larger and slower, which was great, but would be nice if had text size function change over entire range.
- kensai 9y agoI think near the "coins in circulation" as $ rate someone should add a big fat disclaimer: "AT CURRENT EXCHANGE RATE". I know this applies to every currency, but given Bitcoin's volatility, it goes without saying...
- kobeya 9y agoAlso, AAPL is worth $800bn with the big fat disclaimer: "AT CURRENT STOCK PRICES".
- oculusthrift 9y agoyes because apple stock doubles or halves every 6 months and is routinely stolen.
- nebabyte 9y agoAgreed - it's less for the 'this isn't obvious' than the 'this is a well-placed intuitive reminder (or hint) that this number swings around a lot'
- djhworld 9y agoThe money sent metric is interesting, is that what's actually going on right now? I have a miniscule amount of BTC (currently 'worth' £20), I just bought it out of novelty really, never found that much of a use for it outside of buying gift vouchers. Where is all this money going? People just trading the currency between each other? Retail?

- killin_dan 9y agoThis isn't an encyclopedia, it's an informal messaging board. If you want citations that badly, use your old pal Google and go find them. Also, one word posts will almost always get downvotes unless you're answering a question that can reasonably be answered with only one word.
- trakout 9y agoCare to expand on backpage ads?
- hehheh 9y agoHe or she's talking about backpage.com. They're infamous for hosting prostitution ads.
- droopyEyelids 9y agoDo you ever watch highway traffic at an odd time of day? I have the same thoughts about it. Who are all these people? Where do they need to go at 1am on a Monday morning? How did they get the money to buy these cars?
- omarchowdhury 9y agoYeah, the world is a pretty big place.

- mmccaff 9y agoBeautiful design! Care to share any of the details on the tech? Are you using each of the exchange's individual APIs to calculate the weighted average? Did you use any library or framework to help with websockets, or to look at the blockchain? The meaning of "Estimated Money Sent" was a little confusing to me, even after reading the definition on the About page. What do the scrolling numbers in the background mean? I imagine there aren't enough of them to be all of the realtime transactions happening on the blockchain. Also, I'm sure you know, but they overlap when showing as 600x120 in iframe mode. Allowing users to embed the widget in an iframe is nice and a good way to spread the word about your site. Maybe unbury that from the About page and link directly to an 'Embed this' page from the main page, and (as silly as it sounds) use something like clipboardjs to make copying the snippet to the clipboard easier.
- prohor 9y ago1.7 GW power. Wow! That means about 1 ton of CO2 released per hour (according to: https://carbonfund.org/how-we-calculate/ https://carbonfund.org/how-we-calculate/).
- dane-pgp 9y agoFor a more accurate (although still large) value for the amount of power used to secure the blockchain, see here: http://blog.zorinaq.com/bitcoin-electricity-consumption/ http://blog.zorinaq.com/bitcoin-electricity-consumption/ Tl;dr: "the electricity consumption of the network at 3250 PH/s adds up to 470-540 MW".

- CyberDildonics 9y agomost of the mining is being done in china near hydro electric plants where the electricity cost is being subsidized.
- em3rgent0rdr 9y agoThat is only true for burning fossil fules. Considering that the Hover Dam can generate 2 GW peak, the bitcoin network could feasibly run on renewable energy.
- tsukaisute 9y agoSimilar also beautiful page for the Ethereum network: https://ethstats.net/ https://ethstats.net/ (I'm not the author, just a user.)
- oskarth 9y agoI also recommend people check out the author's website: https://johan-nordberg.com/ https://johan-nordberg.com/ - it has quite a neat realtime chat interface.
- alasano 9y agoThis is blowing my mind. I was knocking and wondering why nothing was happening. It simply took Johan a moment to "let me in" it seems? Then we chatted! Impressive if anyone has a link as to how it's built I'd love to see it.
- lelandbatey 9y agoHoly crap that's really cool! For one, the interface is very pretty, for two he is actually chatting in real time with you once you enter the site! I asked him how he does it, he says he built the chat mostly as a frontend to Slack, so he gets messages on his phone and can respond to them on his phone. Pretty cool!
- chias 9y agoHah! I assumed it was a bot at first. But then it started responding to me all humanlike. Very nice.
- dorianm 9y agoAnd his actual website: http://jn.cx/ http://jn.cx/
- eGzg0t 9y agoI asked him if he can let me out so that I can knock again as a joke but it turns out he can do that. I was laughing my ass off.
- wklm 9y agoI'm wondering what are they using

- alex_duf 9y agoThe amount of power we're wasting computing a giant rainbow table drives me mad. We could at least burn coal to compute something useful. I'm not dismissing bitcoin altogether as it brought a great deal of interesting concepts, in fact I even mined a very small quantity once uppon a time. But right now the whole hashing random number madness is mostly a waste of energy. I don't think we should afford 1.7GW (apparently 500MW according to a comment bellow) of power as long as we're still burning fossil fuel somewhere on earth.
- DINKDINK 9y agoWhy aren't you mad about all the gigawatt hours that are wasted powering banks, bank servers, armored trucks silly moving fancy paper from business to banks, printing presses, the distruction of various ecological areas to take the mineral gold out of the ground, VISA servers, printing Visa cards etc. Just because the method to defend against unmodified database entries in the Bitcoin blockchain is very evident and the evidence of ecological cost to our current financial system is largely silent doesn't mean one can ignore those costs.
- alex_duf 9y agoIt's the nature of the computation that bugs me. We have a network growing exponentially relying on the fact that we're hashing random numbers. Academic research aside, it sounds very useless. That has nothing to do with the way banks are doing their maths or maintaining their infrastructure. Again, I'm also very grateful of bitcoin demonstrating we can exchange value without a 3rd party, but it looks like nowadays we could do better. Now in regard of the destruction of ecological areas, mining gold etc... I simply agree with you.
- eru 9y agoSome people have looked into securing a blockchain currency with some other more useful computation. So far nothing much has come out of it, and there are some theoretical reasons why we shouldn't expect too much.
- oculusthrift 9y agois there any reason this is trending? i've been using this site for years..
- macawfish 9y agoRecently, Bitcoin nearly hit $3000. I think a lot of people are curious about what this all means.
- awqrre 9y agoI usually use https://btc-e.com/ https://btc-e.com/ because it also offers the value of other coins...
