This Week in Ethereum 47

###Current Status

We are in the last days of preparing the POC-7 release. It is scheduled to ship on 21th of November. Latest stable release is Po6, testnet is reachable here, chain explorer here. Release of PoC8 is expected to be on christmas. Alpha releases are expected for mid January 2015. Release of the genesis is scheduled for March 2015.

Protocol

  • Version update to eth:34

  • Blogs/Blooms/Recipes There are often going to be situations where contracts need to record events that will be indexible/accessible/provable by light clients and these events are often fire-and-forget. So filling a storage index for them is very wasteful. We solve this by adding a an opcode LOG, whose purpose it is to create an event that gets put into the receipt trie of the block but is not stored in the state. The transactions trie is split up into two tries. (1) transactions only (2) medstate, gas, and logs (the recipes)

  • Exception severity uniformity See: https://ethereum.etherpad.mozilla.org/14
