``` sed -z -i 's/Type: Standards Track/Type: Specification/' bip-0*.md sed -z -i 's/Type: Standards Track/Type: Specification/' bip-0*.mediawiki ``` After the scripted changes, the changes to BIP-40, BIP-41, and BIP-63 were undone, because it breaks CI. These three BIPs only exist conceptually and their proposal documents are missing which causes changes to them ot break the CI. I defer the changes to these BIPs to a separate pull request to get CI to pass.

|
==Abstract==
|
|
|
|
Simple, one-time increase in total amount of transaction data permitted in a block from 1MB to 2MB.
|
|
|
|
==Motivation==
|
|
|
|
# Continue current economic policy.
|
|
# Exercise hard fork network upgrade.
|
|
|
|
==Specification==
|
|
|
|
# MAX_BLOCK_SIZE increased to 2,000,000 bytes at trigger point.
|
|
# Increase maximum block sigops by similar factor, preserving SIZE/50 formula.
|
|
# Trigger: (1) Block time 00:00:00 on flag day, AND (2) 95% of the last 1,000 blocks have signaled support.
|
|
|
|
==Backward compatibility==
|
|
|
|
Fully validating older clients are not compatible with this change.
|
|
The first block exceeding 1,000,000 bytes will partition older clients
|
|
off the new network.
|
|
|
|
==Discussion==
|
|
|
|
In the short term, an increase is needed to continue to current
|
|
economic policies with regards to fees and block space, matching
|
|
market expectations and preventing market disruption.
|
|
|
|
In the long term, this limit should focus on reflecting the maximum
|
|
network engineering limit.
