Lightning network is already available on mainnet, so it is included (see here: https://lnmainnet.gaben.win --> +2000 nodes, with ~6000 channels). What do you mean by layer 2 development and inclusion? Perhaps be a bit more specific? Is it applications, that work "on the bitcoin blockchain"?

Yes, I actually meant applications that work on the bitcoin blockchain.

The chances of LN being included in what?

The chances of LN being included as part of the bitcoin-core and hence compelling people (still centralized exchanges and other outer-layer financial institutes) to upgrade their systems to a truly decentralized one. There's a high chance that I may have missed out on some important information or misunderstood, it has only been a month since I started and the extent/depth of information is overwhelming. Please pardon my misunderstandings, if any.

Not knowing how comment notifications actually work, tagging you @PieterWuille Sir, so that you may be notified.

Perhaps split your question up into separate ones; they're not all that related.

@PieterWuille Sir, I have edited the question to rephrase what I actually intended to ask. Since you have been through the process of a successful release in the bitcoin core v0.13 followed by rigorous testing for about a year and a half, concluding with a 20 core-member review before the mainstream adoption of SegWit, I think your answer could be enlightening. The decision of avoiding a hard-fork with the implementation of the block size being increased (SegWit2x ?), would probably be my next topic to research on.

Post SegWit Inclusion, how long until Lightning Network is included in the core?

### Introduction - Reason for asking this question

With most of the money in the cryptocurrency domain still being utilized in transactions on crypto-exchanges and the numerous hacks that have previously occurred, centralization of the exchanges and their respective wallets have become a major concern.

Though centralization can resolve a lot of issues currently present in the blockchain (majorly referring to bitcoin while addressing this question), there are highly potent second-layer technologies that can achieve the same in a decentralized fashion.

### Lighning Network - theQuestion

While being a second-layer (and not requiring a hard-fork for implementation) technology that solves the use case of micro bitcoin payments and further reducing (probably) the transaction fees, LN (from its documentation) champions the possibility of micro-payment/transactions and fast confirmations, while keeping the block size same and also bringing bitcoin payments to the level of mainstream adaptation as a medium of universal payments.

It also solves the problem of the evergrowing transactions record-keeping (heavy storage memory consumption) by not recording useless intermediary transactions on the blockchain.

> Schnorr probably is also a viable solution for the block size optimization

Though the implementation of this second layer technology was/is heavily dependent on SegWit (malleability) and MultiSig and that being resolved, what are the major roadblocks for the LN to make it to the bitcoin core?

### Second Layer Development and Inclusion (optional extended question)

How does one determine the viability of a second layer technology being included in the bitcoin core and what are the pre-requisites that are to be met for inclusion?
