Description

Release v1.3.1 is a maintenance release to support PBSS on BSC.
PBSS stands for: Path-Based-Storage-Scheme, which is used to optimize the MPT trie tree access, to improve its efficiency and also brings the inline state prune. You could refer this post on how it works: Geth Path-Based Storage Model and Newly Inline State Prune

Currently, PBSS is disabled by default, use this new flag to enable it: --state.scheme path
Important
Before use PBSS, you need to make sure your MPT storage in levelDB are already in PBSS format. There are 2 options to get the PBSS storage:

• 1.Full sync from genesis with the flag: --state.scheme path. // Not recommend, could take 3 months to catch up the latest block.
• 2.Use the converting tool, refer: cmd/geth: add hbss to pbss convert tool #1882. // Recommend, could take ~3 days to complete the MPT convert from HashBased to PBSS.

Compatibility

PBSS will have a new MPT storage scheme, although it is still based the Key/Value database, like LevelDB. HashBased storage could not use PBSS and vice versa.
