It is tough to give very brief summary on lightinig Network but I will try to be very brief and put as much information in less words.

Why we need Lighting network?
The current bitcoin network will not be able to handle if we have to do transactions on large scale as current network will able to handle only 7 (tps) transactions per seconds (which is nowhere when compared to 56000 tps capablity of VISA and handling 4000 tps during peaktime.) So Lightinig Network is a proposed solution that will able to help in doing billion of transactions per day without affecting the blockchain.

How Lightining Network will work?
When two parties are interacting with each other on regular basis then they can commit to signing the transaction  without broadcasting to global bitcoin blockchain. This will remove dependency from blockchain. They can create fund into a 2 of-2 multisignature address (where it requires consent from both parties to create spend).

Micro payment channel created above will create relationship between two parties only. To make bitcoin scalable we will need  a large network of channels on the Bitcoin blockchain. That network will be lighting network.

Lightinig Network will use Hashed TimeLock Contract for security of transactions.

Benefit of lightining network
Rapid payments: payments within an established channel can be made almost as fast as data can travel over the Internet between the two peers.
No third-party trust: the two peers in a channel pay each other directly using regular Bitcoin transactions (of which only one is broadcast) so at no point does any third party control their funds.
Reduced blockchain load
Channels can stay open indefinitely
Rapid cooperative closes
Outsourcable enforcement
Onion-style routing
Multisignature capable
Securely cross blockchains
Sub-satoshi payments
Single-funded channels

Current vulnerability in Lighting network.
Improper Timelocks: Participants must choose timelocks with sufficient amounts of time. If insufficient time is given, it is possible that timelocked transactions believed to be invalid will become valid, enabling coin theft by the counterparty.
Forced Expiration Spam:If a malicious participant creates many  channels and forces them all to expire at once, these may overwhelm block  data capacity, forcing expiration and broadcast to the blockchain. The resultwould be mass spam on the bitcoin network.
Coin Theft via Cracking: As parties must be online and using private keys to sign, there is a possibility  that, if the computer where the private keys are stored is compromised, coins will be stolen by the attacker.
Data Loss : When one party loses data, it is possible for the counterparty to steal funds.
Forgetting to Broadcast the Transaction in Time

All these vulnerablity can be mitigated and Lighting Network will give Bitcoin Network to do billion transactions in a day using the desktop/Home pcs.

In short, Lightning Network will be bidirectional micro payment channel that will help to solve the problem of scalablity in bitcoin Network.

Hi Pugman
I am eagerly waiting for the next question.

@TMAN.

Nice to see you in the beginners forum. May be your's and Jetcash effort will help the forum in long run.

@TweetBirds
If you are looking for help, you will find it here then

you can share your findings in below thread:
https://bitcointalk.org/index.php?topic=1926895.240

Global Moderator rickbig41 is active there and ban the users.

I do not agree with subject of topic as it indirectly implying that all "Newbie-Jr.Member" here are for spamming or all the spamming in this forum is done by "Newbie-Jr.Member". I can agree that there share in spamming is largest of all ranks but topic should be "about stopping spamming" and not to target  a specific ranks in this forum.

Here is my suggestions.
1. Ban all the campaigns that require user to post more than 10 post a week.
2. Formal KYC  for the accounts that are putting "Announcement" and "Bounty" threads in Alt coin board. My personal view  is that these scam developers
    are main reasons for the spam in forum.They give fraction of  there coin/token to users here to spam the forum, sell there coins/token in million dollars
    and then disappear. So basically they are able to spam the forum with zero cost incurred to themselves and without any revelation of their identity. If
    they need to reveal their identity they will not engage/promoting there scam coin in this forum.
3. Do not allow to create more than 2 accounts (or at max. 4) from same IP address and allow people to self delete there accounts.(because sometime
   people create these account for scam accusations only and do not use that account again, so deletion of these account should be allowed.)
4. Official spammer black list, if 3 posted post of a user in a week period are found spam, then disable the signature for 2 week, temporarily suspend user
   and   put formal entry of user in spammer blacklist and signature of user will be disabled until  the username is cleared from this list.
5. Attach the accounts with Phone numbers (I know Theymos/People will not agree as it will cause KYC). But I am sure Account Farmer will not keep 100's
    of active phone numbers.

Not only these, you will get lot of scam videos in which people will suggesting to buy a ponzi coin to others for their referral bonuses.

So is it correct that even if nobody  do any transaction (for assumption) and miners are mining then they still find/create a block.

I was wondering how the bitcoin network started. I understood that genesis block is first block, but from where the first bitcoin created to mine that first block.
(Means even for mining that first block we should have a bitcoin and couple of address to do the transaction, so how this first bicoin come into existence.)

I think every forum has different parser/ or different standards because I checked your same code in some other site code checking box and that code was working as intended.  I read few tags from outside tutorial and they do not work here.

I am also new and no idea what is standard being followed in this forum. you can try your luck by asking your same question in below topic.
https://bitcointalk.org/index.php?topic=1727100.0

I found SFR10 also very experienced but not sure whether he will replies to PMs.

I think these big Corporations will gather these data create some new subject like "Selling Engineering" in which they will target the particular individual and decide what they should try to sell that individual at what price or so on (Extensions to Analytics,Forecasting or Customer Demographics etc.)
I think Selling Engineering  (or whatever system these corporation will create) will just be legal form of Social Engineering.

Hi Rickbig41

can you please take a look on below topic also.

https://bitcointalk.org/index.php?topic=2855895.100
 
Some users reported copy paster there also.

Merit is acting like medicine in this forum but when tooth is decayed too much then dentist extract the decayed tooth instead of giving medicine.

So I donot think Merit can control spam but it will be able contain the spammers in their ranks.

Anyways this is way to search the forum using forum search engine but everybody agree that forum engine is somewhat fuzzy.
Better to use google search in this forum..

Way to do this kind of search.

1. Go to google.com
2. In google search bar type below
 site :https://bitcointalk.org   Search string

Here you can replace "Search string" with any of your keywords to search

Hi roslinpl
Thanks for your great tutorial.

I have few questions.
1. Apart from 4000 characters, do forum put limitation on 3 lines? (as you asked to quote p  3 times in different line.)
2. How these p and "pt" will relate to each other?  I read signature above 42 pt will also be not displayed.

Any particular reason was given for not implementing the suggestion? Actually I am not in mission to catch copy-paster , but they are so widespread in forum that I automatically find them.  A Banned list is not only useful for people reporting them, but it will cause fear in copy-paster too. When they see that so many user are Permabanned , they will automatically mend their ways.


Have you tried that? My personal experience is that Mods/Admin rarely reply to PM.

I already stated you " normal moderator  do not have capability to ban the user. "
I am sure when  you see duplicated content , you automatically recognize it but you need to use your memory+Google search to find that original URL. I even found people that copied from the local language board , used "Google translator" and posted in English forum.
 
I just want to say if I  find copy-pasted content, I can just refer to single list and single thread (that will be much easier), It will also serve lesson for other stupid users that copy pasting causes ban.

I guarantee, you will get one thread less in Meta daily, because these copy-paster when banned create a thread here to ask Why banned ?
Creating a list and single official thread is fair to everybody.  

 

It is not a good choice to give the whole URL when some time people copy in parts. I did not understand why you both want to duplicate the effort by others when user might be already banned or reported by others.

"Report To Moderator" is for reporting shit post/cross post and it goes to normal moderator queue that do not have capability to ban the user.
 

Whenever I encountered a copy-paster, I always report them. Reporting them require me to find the existing thread ,archiving and quoting the evidence and file my evidence report in any one of the below thread.

https://bitcointalk.org/index.php?topic=2855895.0  by marlboroza
https://bitcointalk.org/index.php?topic=1926895.0  by LoyceV

I saw rickbig41 in LoyceV thread banning copy-paster but it does not look to me that moderator has gone through the whole list and below question of LoyceV is still unanswered.


Theymos himself banned some users in marlboroza thread.

So it is proved beyond doubt that forum permabanned for plagiarism but why the forum still not created any sticky thread (and off course a single thread) to report them.

Apart from a single sticky thread , I will suggest to create a list of permabanned user for copy/pasting and moderators giving track that which post of that thread they have processed. This will help in reporting as we can easily check whether user is already banned or reported by other but pending review by moderator so no need to take action or re-report.

PS: It take effort to report the user but when nobody take actions on these reports then it look likes wasted time and effort and in other hand it give wrong signal that forum is not serious about plagiarism.

Apart from this Forum signature, Is BB code is used elsewhere?
In first glance, BB Code look similar to HTML.

Edit: Just figured out everything we write in this forum is BB code only. It never strike to me that we use "[" and "]" here instead of "<>"  as in HTML. Look like BB code is/will be preferred language for forum creation
