9	P3	Wallet	File locks for wallet (needs definition, but might be very desired for Transaction update rework as well)	mimblewimble/grin-wallet#148	"won't be happening just now, it was something I thought might be needed but won't be for the time being"

Wallet P1

• TOR RFC and matching functionality - Optional Tor Send/Listen Functionality grin-wallet#226
• Payment Proofs (which will use TOR addresses/keys but also work without TOR) - Add Payment Proofs grin-wallet#230

P2

• Transaction Update Rework -Rework of wallet output and transaction state update process grin-wallet#244 (Will likely need RFC)

P3

• File locks for wallet (needs definition, but might be very desired for Transaction update rework as well) Storage: implement read/write locks for calls to the LMDB backend grin-wallet#148

Out of Scope

• Interactive CLI for wallet mentioned earlier, justification being there won't be enough time, what we have there in P1/P2 issues is plenty.
