Dear Lisk community,

With this email I want to kickstart the discussion and gather your feedback regarding the LIP "Improve transaction processing efficiency". You can find a short summary of the LIP and link to the LIPS repository below.

Abstract

This LIP proposes to improve the processing of transactions by optimizing the verification of transactions, applying transactions in memory, and consolidating database queries. Additionally, it suggests improvements for managing transactions in the transaction pool.

## Abstract

This LIP proposes to improve the processing of transactions by optimizing the verification of transactions, applying transactions in memory, and consolidating database queries. Additionally, it suggests improvements for managing transactions in the transaction pool.

## Motivation

In the current implementation, transactions are processed by performing application logic and database queries alternately. Furthermore, for transactions which are yet to be included in the blockchain, the database keeps track of the accounts state that would result if all these transactions were applied. This accounts state is called *unconfirmed state*. The *unconfirmed state* is calculated to ensure that transactions do not conflict with each other and it is calculated in the transaction pool and during block processing.
