When Bitcoin (BTC) first appeared on the market, people saw it as a new way to trade and exchange money without intermediaries. The cryptocurrency did not seem very secure, but it still gained great interest among entrepreneurs and investors. Today, 15 years later, Bitcoin received recognition as the main cryptocurrency in the world. BTC is considered a global Internet native currency, and some crypto-enthusiasts even predict a complete transition to a decentralized economic system in the future.
Bitcoin indeed has enormous potential for realizing the opportunities of the Crypto World and transforming the centralized economy into a more convenient and accessible format, but it comes with its costs. The main problem of the number one crypto is its scalability.
Bitcoin is hindered by its own popularity. Due to increased demand (BTC still holds a leading position in the cryptocurrency market), the speed of transactions on the blockchain decreases, and their cost increases. This problem is now being addressed by specialists who are developing new effective protocols. One of such solutions is the Lightning Network. What is it and how will it help to save Bitcoin?
Lightning Network – what is it?
In 2015, it became obvious that Bitcoin's throughput could not cope with the flow of transactions. Blockchain developer Joseph Poon decided to solve this problem and, together with his colleagues, developed a separate scaling system – the Lightning Network. The concept of this new solution was described in the white paper of the project in 2016.
Lightning Network (LN) is an L2 protocol released on top of Bitcoin that can speed up the process of transferring funds and minimize fees. That is, users will be able to transfer their coins faster, in larger volumes and with lower fees.
The creators of LN noted that Bitcoin itself, without outside help, “is not capable of meeting the needs of the global commerce market”. The Lightning Network system is already being actively integrated by large platforms such as OKX and Kraken.
Pros and cons of Lightning Network
At first glance, it is obvious that the new development has become a salvation for Bitcoin. With a throughput of the world's first cryptocurrency of 7 TPS and an average transfer time of 10 minutes, any acceleration of the process will be a great help. The Lightning Network promises to increase throughput to 1 million TPS! Transaction processing might become instantaneous.
Other advantages of implementing LN also include:
- Lightning Network can reduce the load on the entire Bitcoin network;
- lower fees;
- the protocol preserves the anonymity of users;
- Lightning Network supports smart contracts, which means that it is possible to create DeFi applications with this protocol.
In general, the LN protocol allows Bitcoin to keep up with other crypto in terms of technological equipment, like Ethereum (ETH).
Despite the “noble mission” that the Lightning Network does for the Bitcoin, this protocol has a number of limitations:
- Depends on the Internet. The entire operation of LN completely depends on the stable operation of the Internet.
- Bugs. In the event of a technical or network failure, there is a high probability of blocking the channel, forced closure of the transactions, or even loss of user funds.
- Distribution. Despite the fact that the project has already existed for several years, it is still far from widespread distribution. The developers have to figure out the technical problems in the area of channel creation and management.
Lightning Network and centralization
Some crypto enthusiasts began to accuse the Lightning Network protocol of contradicting the very idea of crypto. Bitcoin was created as a means of decentralization, while LN channels are becoming control centers (analogues of banks in the traditional economic system).
On the one hand, such a policy violates the principles of direct transfers without intermediaries. Moreover, large Lightning Network nodes are capable of monitoring transactions, censoring the activities of unwanted users, and they are not immune from government decisions. All this does not fit in with free anonymous trade.
On the other hand, potential centralization within the LN can act as a security authority for the system. With the help of controllers, you can resolve disputes that arise during the transfer of funds and restore access to coins lost as a result by backing up data.
The future of LN and Bitcoin
The Lightning Network system is currently one of the most optimal solutions for the Bitcoin network. The technology allows this cryptocurrency to move forward and serve even more users around the world.
The problems of the system itself (namely the problems of token liquidity) are now being actively addressed by the developers. Despite some difficulties, investors and entrepreneurs continue to support LN. In 2022, Lightning Labs managed to raise $80 million to develop a new Taro protocol that works with stablecoins. One of the investors was former Twitter CEO Jack Dorsey.
