Lightning adds Smart Contract interoperability to Bitcoin

Lightning @ 22:37 minutes

So what follows is a brief discussing Lightning.

Bitcoin can (and virtually since forever) process Smart Contracts. An example of this is a multi-signature wallet, which is an example of a Smart Contract; however, compared to Ethereum, Bitcoin is programatically inefficient.

This means that it is quite expensive to utilize the Bitcoin Smart Contract features — whereas Ethereum might allow 1,000 lines of code modifications for a small fee, Bitcoin allows only 1 line. Thus, adding in 1,000 lines of code increases fees 1,000x, vs a few pennies on Ethereum.

Aside: the intention behind this is to steer Bitcoin toward retaining its core properties of node distribution and value transfer, not to serve as an ultra expensive Github or Wikipedia. Today, there are far, far more nodes run by Bitcoin users than Ethereum users, and a Bitcoin node requires $100 of hardware compared to an Ethereum node necessitating $1,000 for similar performance (note: it is common propaganda amongst Ethereum pumpers to declare full archival transaction indexed nodes an unnecessary luxury for the modern man, but it is the opinion of this author that such statements are designed to confuse rather than educate a common audience).

Lightning, however, better incorporates Smart Contract functionality into the Bitcoin blockchain.

The Lightning network is a series of single-purpose Smart Contracts with one purpose only: to track value transference, initiated and settled over the Bitcoin blockchain.

Again, as with Bitcoin, the intent is not to store the Encyclopedia, but to track value. This is highly important, as it makes the code storage requirement still very minimal and relatively easy to process — but it enables one key feature, which is Smart Contracts executed efficiently via Bitcoin; but there is more to it than that, and that is where interoperability comes in, generically referenced as ‘atomic swaps’.

Ignoring the buzz, this is simply two Smart Contract platforms sharing a common interaction. A base example could be the Ethereum database interacting with the Neo database, so that someone transfers 10 OMG tokens to a new ETH address while transfering 1 NEO token to a new NEO address — each occurring simultaneously, or put more precisely for finality to be reached only after the occurrence of each, or the disoccurance of one prevents the finality of either (or issues an unstoppable automatic reversal).

Now, what you have with Bitcoin is the possibility of it interacting with the Lightning network, which could in turn interact with a variety of other blockchain databases.

This could pave the way for ICOs and similar creations to utilize the Bitcoin network for transferances of value (similar to Ethereum) or to interact with other blockchains in a like-minded fashion; some could refer to this as the Bitcoin Exchange or perhaps more poetically ‘the rainbow road’.

Aside: it is important to note that unlike Ethereum, each token or alternative blockchain would need to maintain its own databases or sources of ‘decentralized distributed data’. Whereas Ethereum houses millions of kittens, the Bitcoin borders are rather closed; preserving consistent quality.

Lastly, regarding cost, the fee to run a complex Ethereum transaction can be 100x more than the cost of processing a standard movement of Ethereum. However, the cost for processing a series of Lightning transactions is a small fraction of the cost of processing a Bitcoin transaction, and any interoperable blockchains would set a fee relative to itself.

So while Ethereum kittens are housed at the same cost of storage as that of its credit card substitute, Bitcoin transactions always maintain priority; and theoretically all Lightning contracts could be batched into 1 transaction per block; and all interoperable data batched within Lightning.

So, in the post-Segwit world of Bitcoin you have 10x the available space for Bitcoin transactions and Lightning interoperability, creating a more colorful and expansive world for interactivity, without fostering a technological addiction, growing with prolonged or continued use; with Bitcoin, Lightning, and interoperability the Bitcoin blockchain is strained by 1 transaction per block, or 9 MBs per year, while providing comparable functionality to that of other modern Smart Contract platforms.

Some could argue more reliably, and others more cumbersome, but I will leave the reader to choose.

Hope you have enjoyed this exploration into the Bitcoin blockchain. To participate in our Thursday discussions, email Our prime group meets at 8pm EST, however if sufficient quantities of Europeans, Pacificans, or Asians express interest than we will add more time slots; each meeting is limited to exactly 8 people, with a representative elective system for scale. For more information, partake :)
