Problems with Bitcoin’s Lightning Network

Transactions may be made between parties not on the Bitcoin blockchain or “off-chain,” using Bitcoin’s Lightning Network (LN).

As a result of the Lightning Network, bitcoin has been a game-changer in its progress.  Due to this, the Lightning Network has its own set of charges associated with using it.

Work in progress: Lightning

However, the Lightning Network has been the subject of much contentious literature and media coverage.

When discussing Bitcoin’s scaling issues, it’s either a perfect product that can solve all of Bitcoin’s problems or a poor notion that it should be put aside for a different coin.

We surveyed developers to determine what they were most worried about and what they believed to help Lightning’s adoption grow.

All of their responses are here in the report. Excellent – but what’s broken?” is another common refrain from developers when it comes to Lightning.

Because they want Lightning to succeed, they do this. Breakthrough innovations require a critical eye to ensure their long-term viability.

PROBLEMS IN STATE MANAGEMENT

As long as you don’t spend the same amount of bitcoin twice, the transaction is legitimate. Both parties can’t sign new transactions without the other’s agreement since Lightning channels are 2-of-2 multi-signature.

Unless the other party agrees, you cannot invalidate any of the pre-signed trades you have made on the chain. To maintain this channel, both of you must update it simultaneously.

If either of you could act on your own, one of you could walk away with the entire pot of money.

RESPONSE TIMELINESS

A Lightning payment must be signed twice by every node engaged in its path if it will make it across the network in one piece. Once you set up the amount using HTLCs, you clear the HTLC and settle.

This creates a “weakest link” dynamic in terms of how quickly a payment can clear. If you’re a regular user of Lightning, you may notice that payments sometimes take a few seconds (or perhaps a few minutes) to be processed and reflected in your balance.

It can take anything from 5 to 20 seconds for a transaction to go through using Breez.

Viability of the Channel Amount

On-chain fees significantly impact many aspects of the Lightning Network, not only HTLCs. Lightning channels themselves fall subject to this phenomenon as well.

There is a Lightning channel with $10 of BTC capacity, yet the on-chain charge for that transaction is only $1.

There is a ten percent cost for establishing this channel. Your effective charge rate drops to 1 percent when you put $100 into a canal. 

In other words, the Lightning Network now has an actual market floor where users may engage with it directly.

To open a channel, they will not open it if the effective price rate is excessive. In this dynamic, the only meaningful trade-off or solution is the passage of time.

You can submit your channel-opening transaction with a reduced cost if your funds are less than $100 and you do not wish to pay a 10% fee. 

HTLC ISSUE

HTLCs is the subject of the following two key concerns (Hashed Timelock Contracts). It is a new output added to the pre-signed transactions that say, “If you know a secret, you can claim the money, or the sender can recover it after a waiting time.”

They employ Hashlocks and timelocks. If the final receiver discloses the secret, everyone who helped to transfer money through their channels is entitled to a portion of the payment; if the recipient doesn’t divulge the secret, everyone gets repaid after a certain amount of time has passed. 

TOR IS REQUIRED

Even non-technical users should be aware of one of Lightning’s most significant drawbacks: you must be online to utilize it because sending and receiving is a two-way communication process.

To put it another way, if two peers want to communicate, they’ll require IP addresses. When you have to provide your IP address to your channel peers, it is an important privacy and even censorship concern for ISPs who wish to see whose IP addresses communicate.

Currently, Tor is the most popular option for dealing with this issue. The trouble with it is. that Tor has its own set of difficulties. It relies only on a volunteer-run reputational authority.
