#LIGHTNING SCHEDULE FULL#It can be argued that running LN is not too much more difficult than running a full bitcoin node, though. Running a LN node can be quite difficult and it could be the case that there are payment incentive problems for running smaller nodes. For LN to be successful, it requires a robust network of Bitcoin nodes running the LN protocol. There are concerns about how easy it is to run a LN node. As such, it is faced with many challenges ranging from usability to security. LN is a new protocol still in the testing phase. Node A transacts with node Q despite only having direct payment channels with nodes C and B. Over time, by the theory of six degrees of separation, LN allows Alice to transact with anyone else. Note that in this scenario, Bob might take a small payment for passing on the transaction. What if Alice wants to transact with Carol? Well, it so happens that Bob has a payment channel with Carol, so Alice transacts with Bob, and Bob passes the transaction on to Carol. In this case, Alice’s final balance is 11 BTC and Bob’s is 4 BTC. When one or both wish to close the channel, a closing transaction is sent to the blockchain with the final balances of Alice and Bob. Below are transactions between Alice and Bob: Once that transaction has been added to the blockchain, which can take 10 minutes or more, Alice and Bob can transact an unlimited number of times at much faster speeds and effectively zero cost. An opening transaction holding Alice and Bob’s combined 15 BTC is put onto the Bitcoin blockchain. Alice commits 10 BTC and Bob commits 5 BTC into the payment channel. Let’s look at an example to illustrate this:Īlice and Bob want to form a payment channel with each other. The total amount of Bitcoin that can be transferred through this channel is the total amount of Bitcoin committed. That Bitcoin is held and cannot be released as long as the payment channel remains open. To start a payment channel, both parties must commit an amount of Bitcoin. Any number of transactions between the first and last will happen off chain, which means those transactions are not limited by the Bitcoin protocol. LN works by setting up a payment channel between two parties, where only the first and last transaction are put on the Bitcoin blockchain. This means that it allows the Bitcoin protocol to remain relatively unchanged, but provides the benefits major reworkings could bring - in theory, at least. The Lightning Network, rather than creating a new blockchain, is a layer-2 solution.

Since blocks are added to the chain approximately every 10 minutes, there is a hard limit to the number of transactions possible without significantly altering the Bitcoin protocol. The limiting factor of the Bitcoin network is that every transaction must be put in a new block on chain. To understand how LN works, and the current challenges of LN, we need to talk about Bitcoin. But if Bitcoin is to be used for everyday payments (so-called micro-transactions, e.g., a cup of coffee, gas), the transaction speed must increase and transaction costs must decrease drastically. For large transactions, such as bank transfers or international remittance, Bitcoin’s speed and cost is comparable or superior to alternatives. For instance, on April 20th 2021 average transaction fees were in excess of $50, while on August 9th 2021, the average was around $2.50. Contrast this with traditional payment processors like VISA, which handled on average 6,000 TPS in 2020 (based on VISA’s claim of 188 billion transactions a year).īitcoin’s transaction fees can vary wildly depending on the current demand to use the network. LN was created in response to scalability issues with Bitcoin, namely the speed and cost of Bitcoin transactions.īitcoin’s current theoretical maximum transactions per second (TPS) is 10, though in reality it is between 3 and 7. Proposed in a white paper in 2016, the Lightning Network (LN) is a layer-2 solution built on top of Bitcoin.
