As said in Péter Szilágyi post DAO Wars: Your voice on the soft-fork dilemma:

Miners supporting the DAO soft-fork can do so by starting Geth 1.4.8 with --dao-soft-fork. This will cause the block gas limits to be lowered towards Pi million until the deciding block 1800000 (approx. 6 days from now) is reached. If the gas limit of this block is below or equal 4M, the soft-fork goes into effect and (all updating) miners will start blocking DAO transactions that release funds.

How does the Geth (or Parity) client knows the current global network gas limit ? I can't see any explorer that shows it except https://ethstats.net/ that only shows some voluntary nodes.

The block gasLimit is in each block. Example:


  difficulty: 34982465665323,
  extraData: "0xd783010305844765746887676f312e352e31856c696e7578",
  gasLimit: 4712388,
  • "Is in each block" was the key. I was looking for a global data... thanks. Jun 24, 2016 at 22:55
