The End of Rent Collection: A Major Shift in Solana's Architecture

One of the most notable announcements in this changelog is the proposal to remove rent collection from the Solana runtime. This development, outlined in SIMD-84, marks a significant evolution in how Solana handles data storage costs on the blockchain.

The History of Rent on Solana

When Solana was initially created, users had to pay rent upfront for all data stored on the blockchain. This system was designed to ensure efficient use of network resources and prevent unnecessary data bloat. However, as the network evolved, this approach was refined.

The Current Rent System

The current system requires users to pay two years' worth of rent upfront when creating new accounts. This change has significantly reduced the number of accounts subject to ongoing rent collection, leaving only a small number of older accounts still paying rent periodically.

The Proposal to Disable Rent Collection

As the number of non-rent-exempt accounts continues to dwindle, the Solana team has proposed removing the rent collection feature entirely from the codebase. This move would streamline the Solana runtime and potentially improve overall system efficiency.

Jacob commented on this development, saying:

"It's really cool that it's kind of like lining up that it's been what roughly two years since rent was disabled to where you could create non-rent exempt accounts. And now that they can finally remove this, they can't. It's cool to see."

The Future of "Rent" on Solana

While the removal of rent collection is a significant change, it's worth noting that the concept of "rent" in Solana might be due for a nomenclature update. As Jacob pointed out:

"It's kind of getting to the point where I would personally like to see rent changed as like what it's called because it's my house more of a deposit. And the concept of an actual rent is different."

This observation highlights the evolving nature of Solana's architecture and the potential for further refinements in how the network describes and handles account storage costs.

Implementing the Rent Collection Disable Feature

In line with the SIMD-84 proposal, a new feature has been merged into the Solana codebase. This feature will allow for the disabling of rent collection when the time is right.
