@winsvega @jwasinger Added!

An interesting EIP raising the question of concurrency and locks for storage: ethereum/EIPs#718.

There is already some discussion about it in the EIP and perhaps by bringing it up in the meeting we can see opinions of other core devs on the topic: ethereum/EIPs#718

[axic]

Perhaps we could agree on the bitwise shifting EIP: ethereum/EIPs#215. There is one change from last time: the operand order was swapped to match more natural use cases (shifting a value already on the stack and as such removes the need for swap)

[chriseth]

I think we should also slowly bring up account abstraction again. How do the toolset providers think about it? Did we find better solutions in the meantime?

[chriseth]

Something that does not yet have an EIP (at least I think): Some way to reduce the gas costs for an SSTORE if that slot (or the whole contract) is destroyed at the end of the transaction ("ephemeral storage"). This is useful for mutexes and auxiliary data that is passed to contracts deep inside the call chain but that we neither want to pass along all the time nor store permanently in some data storage contract.

[holiman]

@chriseth would SSTORE be the best vehicle for ephemeral storage? Or would a new type of memory be better?

[chriseth]

@holiman open to anything as long as it solves the use-cases :-)
