The email thread revolves around the block size limit in bitcoin following the segregated witness upgrade. Ryan argues that the block size limit has been replaced by a more restrictive block weight limit, while Eric maintains that the previous rules remain in effect and no rule has been "replaced." However, both agree that additional rules have been applied to further restrict block validity and consider additional data in the context of the block.Specifically, the block size limit of one megabyte has been replaced with a block weight limit of four million weight units. Although there is a debate over whether this constitutes replacing a rule or adding a new one, it is evident that the new limit is more restrictive than the previous one. As a soft fork, all preceding rules continue to apply, and blocks must validate against pre-SegWit rules to be considered valid.The discussion also touches upon the increased block space enabled by the segregated witness upgrade. The upgrade replaces the 1MB block size limit with a block weight limit of 4M weight units. Bytes sent to old clients are weighted at four units each, allowing for compatibility as a soft fork. It is emphasized that all preceding rules remain in effect, and blocks must adhere to pre-segwit rules to be deemed valid. Additional rules are introduced to further restrict validity and account for additional witness data.CANNON raises a question regarding the extra block space beyond the legacy 1 MB limit and whether it is exclusively allocated to witness data. The response clarifies that the block size limit has indeed been replaced by a block weight limit, and there are no separate limits. Bytes sent to old clients are assigned a weight of four units each, enabling the soft fork implementation. The email from CANNON includes a PGP signature, ensuring secure communication, and serves as a reminder that any unsigned or unencrypted email correspondence should be considered potentially forged and not private.On February 18, 2018, a question was posed on the bitcoin-dev mailing list regarding the increased block space resulting from the segregated witness upgrade. CANNON inquired whether the additional block space beyond the 1 MB limit exclusively accommodated witness data. The response confirms that this is effectively the case, with the weight discount applying to the witness data. Furthermore, CANNON's PGP fingerprint and email address are provided for secure communication purposes. The email signature emphasizes the importance of PGP-signed or encrypted correspondence, cautioning against potentially forged and non-private messages. Additionally, an HTML attachment is included, although no further details about its content are provided.In summary, the email thread delves into the block size limit in bitcoin after the segregated witness upgrade. While differing opinions exist regarding the replacement of rules or the addition of new ones, it is evident that the new block weight limit is more restrictive than its predecessor. The discussion also touches upon the increased block space enabled by the upgrade, with clarification that the extra space primarily caters to witness data. The inclusion of PGP signatures and reminders about secure communication highlight the importance of privacy and authenticity in email correspondences.
