The proposal to lower the minimum transaction fee in Bitcoin is called the **Dust Limit Reduction Proposal**. It was first introduced in 2019 by Bitcoin developer Matt Corallo. The proposal would reduce the minimum transaction fee from 1 satoshi to 0.000001 Bitcoin, which is about one-tenth of a cent.

The Dust Limit Reduction Proposal has been met with mixed reactions. Some people support the proposal, arguing that it would make Bitcoin more usable for small payments. Others oppose the proposal, arguing that it would make the Bitcoin network less secure.

The proposal is still under discussion, and it is not yet clear whether it will be adopted. If it is adopted, it could make Bitcoin more usable for small payments, but it could also make the network less secure.

Here are some of the pros and cons of the Dust Limit Reduction Proposal:

**Pros:**

* Would make Bitcoin more usable for small payments.

* Would make it easier for people to experiment with Bitcoin.

* Would reduce the amount of "dust" in the Bitcoin network.

**Cons:**

* Could make the Bitcoin network less secure.

* Could encourage people to spam the network with low-value transactions.

* Could make it more difficult for miners to earn fees.

Ultimately, the decision of whether or not to adopt the Dust Limit Reduction Proposal is up to the Bitcoin community. There are strong arguments on both sides of the issue, and it is important to weigh the pros and cons carefully before making a decision.
