 ## Abstract
 
-This RFC delineates the specifications for CKB-VM version 2. CKB-VM version 2 pertains to the version implemented in the CKB 2023 hardfork. It is important to note that this version is distinct from the version of CKB-VM available on Github or [Crates.io](http://crates.io/).
+This RFC delineates the specifications for CKB-VM version 2. CKB-VM version 2 pertains to the version implemented in the CKB Meepo hardfork. It is important to note that this version is distinct from the version of CKB-VM available on Github or [Crates.io](http://crates.io/).
 
 ## **Motivation**
 
-The upgrade of CKB-VM in 2023 aims to enhance the security, portability, and efficiency of scripts. Throughout recent years, several questions have been a source of concern for us:
+The upgrade of CKB-VM in Meepo hardfork aims to enhance the security, portability, and efficiency of scripts. Throughout recent years, several questions have been a source of concern for us:
 
 - We currently lack a secure and straightforward method to invoke one script from another.
     - The **[dynamic library call](https://github.com/nervosnetwork/rfcs/blob/master/rfcs/0009-vm-syscalls/0009-vm-syscalls.md#load-cell-data-as-code)** presents a security concern. The sub-script and parent script share the same memory space, leading to an uncontrolled security risk when calling an unknown sub-script.
