+ +==Abstract== + +Increase total amount of transaction data permitted in a block from 1MB to 2MB on November 11, 2015. + +==Motivation== + +# Exercise network upgrade procedure. +# Continue current economic policy of low fee pressure on average. + +==Specification== + +# Maximum block size permitted to be valid is 1MB. +# Increase this maximum to 2MB on November 11, 2015 at 00:00:00 UTC. +# Increase maximum block sigops by similar factor, preserving SIZE/50 formula. + +==Backward compatibility== + +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 facilitate +network growth, and buy time for more comprehensive solutions to be +developed. This continues the current economic policies with regards to +fees, matching market expectations and preventing market disruption. + +In the long term, continued direct management of this limit is a moral hazard that clouds free market input and prevents a healthy fee market from developing. This area of code should be transitioned away from direct management. + +==Implementation== + +https://github.com/jgarzik/bitcoin/tree/2015_2mb_blocksize + From 46e70a9a97af23014b456ff9bf5dd9e232b41421 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Tue, 23 Jun 2015 02:54:09 -0400 Subject: [PATCH 2/3] BIP XX - add growth point --- bip-XX-2mb.mediawiki | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/bip-XX-2mb.mediawiki b/bip-XX-2mb.mediawiki index ad9a423954..dbca5326f7 100644 --- a/bip-XX-2mb.mediawiki +++ b/bip-XX-2mb.mediawiki @@ -13,8 +13,9 @@ Increase total amount of transaction data permitted in a block from 1MB to 2MB o ==Motivation== -# Exercise network upgrade procedure. +# Enable network growth. # Continue current economic policy of low fee pressure on average. +# Exercise network upgrade procedure. ==Specification== From 188ee9e718dc12c34d86c2f4886c79c476437f0a Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Tue, 23 Jun 2015 18:18:39 -0400 Subject: [PATCH 3/3] bip-XX-2mb assigned BIP number 102. --- bip-XX-2mb.mediawiki => bip-0102.mediawiki | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) rename bip-XX-2mb.mediawiki => bip-0102.mediawiki (99%) diff --git a/bip-XX-2mb.mediawiki b/bip-0102.mediawiki similarity index 99% rename from bip-XX-2mb.mediawiki rename to bip-0102.mediawiki index dbca5326f7..6694cb8a28 100644 --- a/bip-XX-2mb.mediawiki +++ b/bip-0102.mediawiki @@ -1,5 +1,5 @@
