PrizmCore 1.10.3.42 Changelog

This update is a bugfix update.

It also includes minor Core performance optimizations.

Please note:

On first start PrizmCore 1.10.3.42 will RESCAN blockchain. 

This process is automatic and is going to take from 30 to 60 minutes (depending on a hardware)

1. Fixed false-positive “Double spending” error

We discovered the bug causing some nodes to refuse valid blocks. We revised this problem and made a fix. It requires the blockchain to be re-scanned from height 0. This process is very fast. It will take some time during first start of PrizmCore 1.10.3.42. No additional download required.

2. Fixed “wrong account balance” bug

There was an insignificant potential for incorrect calculation of the account balance with completely correct initial data.

3. Further optimizations of derived tables trimming algorithm

This process has become slightly faster while maintaining more precise processing of an outdated database records.

4. Slight increase in blockchain download performance

Now PrizmCore is using more appropriate mechanism to process transaction data.

It is highly recommended that you apply this update as soon as possible to avoid unwanted downtime.
