	~~==Abstract==~~		{{BipMoved\|bip-0034.mediawiki\|BIP 0034}}

	Bitcoin blocks and transactions are versioned binary structures. Both currently use version 1. This BIP introduces an upgrade path for versioned transactions and blocks. A unique value is added to newly produced coinbase transactions, and blocks are updated to version 2.

	~~==Motivation==~~

	~~# Clarify and exercise the mechanism whereby the bitcoin network collectively consents to upgrade transaction or block binary structures, rules and behaviors.~~
	~~# Enforce block and transaction uniqueness, and assist unconnected block validation.~~

	~~==Specification==~~

	~~# Treat transactions with a version greater than 1 as non~~-~~standard (official Satoshi client will not mine or relay them)~~.
	# Add height as the first item in the coinbase transaction's scriptSig, and increase block version to 2. The format of the height is "serialized CScript" -- first byte is number of bytes in the number (will be 0x03 on main net for the next 300 or so years), following bytes are little-endian representation of the number. Height is the height of the mined block in the block chain, where the genesis block is height zero (0).
	~~# 75% rule: If 750 of the last 1,000 blocks are version 2 or greater, reject invalid version 2 blocks. (testnet3: 51 of last 100)~~
	~~# 95% rule ("Point of no return"): If 950 of the last 1,000 blocks are version 2 or greater, reject all version 1 blocks. (testnet3: 75 of last 100)~~

	~~==Backward compatibility==~~

	All older clients are compatible with this change. Users and merchants should not be impacted. Miners are strongly recommended to upgrade to version 2 blocks. Once 95% of the miners have upgraded to version 2, the remainder will be orphaned if they fail to upgrade.

	~~==Implementation==~~
