that guy is great.. but the first day someone gets interested in bitcoin, it needs to be laymen demonstration. then lesson 2 gets more technical explanation, lesson 3 gets even more technical code snippets..

for instance if
5=consumers
1=github repo's

the guy in the world bitcoin network video's is a 2-3.

bitcoin needs alot more concentration on level 5 consumer based services, options and tutorials

less buzzword wizardry and theory. more layman demonstration.
as i said before on a different page making an escrow (multisig) should not be a command prompt technique where users have to try remember the spellings of the command and the formatting of the brackets, comma's and speachmarks.

the way i imagine it..

imagine you meet a woman in a bar
you dont say i am a trader of a trustless world wide decentralized cryptographically secure public ledger token.
you would say. i trade international currencies

and when they seem interested. you dont say "to use it you need to RPC call createmultisig <nrequired> <‘[“key”,”key”]’>, add the .."
instead you say, "let me show you, let me buy you a drink, waitress ill have bottle of champagne, can you display your QR code so i can pay"

as i think that is the problem with the whole escrow thing.
1. they are bombarded with technical waffle that bitcoin is a trustless peer to peer, blah blah that doesnt need central oversight.. so that makes them think they dont have to worry about trust.
then they know RPC commands are like speaking chinese to a texas rancher, so they just do what they would do on paypal and hand the money over to some stranger who says they offer a escrow payment service

i know you prefer to do the acedemic detailed and technical education. but is there anyone that is involved in the basic "noob guides"?

i thought that blockstream with their price waterhouse backing was meant to be the go to location for the technical /business integration stuff.. but there needs to also be a part of the "foundation" that is there for common users.

EG apple have a technical section for the IOS interested parties and developers. but they also have a "consumer" department too for their front end features, that doesnt waffle about the technical stuff. i dont even think the consumer stuff even mentions the words IOS that often. they just make laymen demonstrations of how to use basic features.. if you get my drift

no. other things do too.. but some dont.

but in some ways signature hashing of sha256 can be manipulated to give false readings.
   hash length extension attack

so although sha256 is safe in regards to how bitcoin uses it.. other applications have been misused

sha 2, is like the category or brief way of saying it

sha3 is the same. it has some variations (Schnorr being one of them)

but to be specific to bitcoin.. its secp256k1

not quite 2 procedures.. check the <includes>..

yep, will have to be a separate GUI... afterall it cant ever be a 'shiny knob' feature in the 'bitcoin engine'.. you need to know RPC commands just to play with the 'engine'.

it could happen, just needs:
user friendly method to perform it
tutorials

it seems most noobs on the trading category of this website have only just wrapped their heads around standard transaction types.
bitcoin lacks basic guides for noobs, something i thought charles hoskinson was meant to be working on.

its like ages ago i proposed for bitcoin based websites to not use usernames and passwords.. but to store a customers public key and then ask the customer to sign a random message using their private key and pasting the message into a login box..

seems it would solve alot of issues and at first light you would think that copying a random message and pressing sign, and copy and paste back was easy as pie.. but even that seemed too complicated for some services

ok maybe not direct sidechains (eg not like a merge mine idea) but there would need to be some decentralised method for swapping in and out, that way your bitcoin gold still reigns supreme as a reserve currency which others are backed by (even if only in theory rather than linked chains)

i think the best way to ensure bitcoins reserve currency status is the sidechain method, where it starts with 6 main sidechains to represent the main world continents

easy enough to close off the mining so only retailers can mine/authorise. so that outsiders cant jump in. EG customers only have lite wallets with no miner code to reveal how the mining/authorisation works. then there would not be any hashpower race. and just basic security distributed across the many retailers of the mall

yep possible could work for a "mall shopping centre" blockchain currency.. i admit that could be a possibility. covering multiple stores. but i dont envision a 1 currency per business as that gets too complicated for customers.

maybe the first step into you achieving it is to promote it first as a loyalty card system for a mall.. and then expand it to allow customers to buy/sell coins, to expand it into a a currency once the retailers are comfortable and trained in using it

blockchains per company will piss people off having to convert each time they use a different store or service..

maybe sidechains, where each side chain represents a continent, or a country.. and if user adoption gets too high in that main area, creating a bottle neck. then new sub-side chains are created to represent a smaller population base of that area ( states, provinces, counties)

that way people are not
1. worried the chain becomes useless if a company goes into bankruptcy, taking their miners offline
2. swapping between currencies every time they want to shop locally.
3. worried funds wont disappear as its based on geographic location rather than company.

also if one company was using a chain.. it would just be a ledger, and no real point in the decentralized blocks.. (unless its a international company or something with 1000 different stores). but even so swapping applecoin for bitcoin then into walmart coin.. or even applecoin after buying an ipad to then change directly into walmart coin to then spend walmart coin.. is a few too many transactions in the middle, that people wont like.

they would prefer however UKcoin  to buy things in the uk and only swap if they are going on holiday abroad

(i expect you to knit pick and whinge like a school girl.. so have a cup of coffee first and think about it for a while)

no, a block can hold upto 1mb of data

1 transaction can be anything from 250bytes+

which means a block holds anything from 1 transaction, (on average 1500) to if lucky, 4000 transactions.

also the time a block is created is not precisely 10 minutes. some blocks can be 2minutes some 1 hour. but the average is 1 per 10 minutes..

this is averaged, due to the fact that every 2016 blocks is calculated as about 2 weeks(2016*10=20160(=336 hours=14 days).. if 2016 blocks are created in less than 14 days after the last difficulty check. it means miners are working too fast. and so the difficulty is increased to slow them down. thus attempting to keep it to the average of 10minutes per block

im from the UK too and in my head, i spell realised with an S.. but this irritating web browser puts a red line under the word forcing me to use a Z instead of an S.

if you check his white paper that is not confined to the crappy web browser racist spellchecker.. where it gives us UK folk more freedom to talk how we brits want. then you will see that he writes like a brit.

so analysing forum posts fails, if you dont take the american spell checker defaulted into the browser into context
(i avoided auto-correct, purely to make a point)

kind of... team core.. AKA blockstream want it to be the reserve currency for their Liquid, which isnt even a true decentralised block ledger. its not mined as such its just signed off on by a dozen pre-selected computers, that way transaction settlement is near instant as its signing off on transactions rather than gathering them up as blocks of transactions. thus no proof of stake/work to be even considered.. just signatures that 12 people agree the data is valid.

but shhh no one is suppose to know that they are trying to kill off usability of bitcoin to shift people over to liquid

its an estimate..it can be more. it can be less.
https://bugsnag.com/customers/coinbase
quotes 1.5mill customers. but i prefer to undersell numbers just to be more fair of regular users as oppose to those who just play with it once and then dont come back

well there are more than 5000 full nodes.. but only 5000 running 24/7.
reasons why they dont run 24/7, because they only do one transaction a day or a week and dont really understand that being a fullnode means running 24/7.
people who are not running businesses dont need the RPC-API connections and so they just run it occassionally.

the reason there is not a 25% usage. is purely because home users dont leave computers on every day and over night.
most of those nodes are businesses and programmers. and hardly any of them are home users.

as for statistics.. well i know ur just baiting me with a trick question. after all bitcoin is decentralized,
but im sure if you do a WHOIS search on the IP addresses found on https://bitnodes.21.co/nodes
you will find alot of businesses rather than users.

so if its a real question you want answers to, ill leave you to investigate


exactly we are not in 2009 anymore.. DSL isnt 2mb down 200k up... its higher.. and as i said fiber is even higher again.
as for 25% american population. which is 79million population so not something to ignore or downplay. i would think that anyone who's mindset is into the internet.. (rather than farmer Joe on a ranch). you know people that are savvi internet users.. are going to be by definition internet ready. and thus if we brush away all the farmer joe's that dont even use the internet and so wont even know or care about bitcoin.. and then just take the demograph that could find interest in bitcoin.. i think you will find atleast 50% of them possibly more are in fibre area's


65-75 connections..?
lol no wonder your complaining
try 7-30 youll be happier.
maybe its worth looking into the term "7 degrees of separation" or the more modern term "7 degree's of kevin bacon" and you will learn that if 7 people who are connected to 7people who are .. blah blah blah eventually everyone is connected to each other.

so complaining about speed and then having your setting up so high, is much like blaming bitcoin for the argument you had with your fibre company.

so relax, set it to 7-30(30 very max) maybe even aim for 20 max. and you'll do fine.

oh and if you are only using it just for a couple hours a day just to resync, and you dont have the community spirit to be a true 24/7 full node.. then knock it down to under 7 connections. you will still get the data. but then you not pissing off the rest of the network by connecting to you temporarily where instead they can connect to other that want to be 24/7 full nodes


wait..so when i shoot a bullet or do a jump or move in the game, those commands only get sent once a day? but magically other players see me moving live and react to situations... are you sure its not a constant pinging of data as fast as my finger can press a key?
because im shocked.. thats like magic.. so i guess call of duty doesnt use the internet to send movement, shooting, target data.. that its instead done through psychic voodoo.. ok i got it thanks

lol 6Tb?

um 2mb=104Gb a year
 to be 6Tb a year thats means the block limit would be 120Mb a block.

um, sorry thats not gonna happen in 2016

so essentially your saying that out of 1 million people in bitcoin. the reason for only 5000 full nodes is due to a possibility that only 0.1% of the bitcoin community can get fibre..

ok..

ill call Activision and tell them that online gaming is impossible because 0.1% of population cant play online constantly.
then ill call blizzard

oh and ill call youtube and tell them that they need to turn off their video upload feature because people cant upload.
wait. next ill call skype as their 3mb a minute video calls (30mb per 10 minutes) are impossible.

anyone else you want me to call? as it seems there must be a problem.. and strangely these services have not been aware..

storage is not an issue.
the mining pools just buys a $100 2terrebyte hard drive..1 per pool, not per asic..

the pool stores the transaction data after all.. and the mining ASICs are just hashing small bits of data. of temporary data that they forget about after the average 10 minutes to work on new data.. (unscrew a asic, there is no hard drive) only the pool needs a $100 hard drive.. not each asic, so relax
