+## Agenda points & Actions
+
+### 0. Retrospective
+* _ignopeverell:_ Main two themes were preparation for grincon0 and consolidation. Beside traveling and presentation, there have been a lot of cleanup and small enhancements, for example @hashmap and @antiochp collaborated around removing a lot of the unsafe code we still had around. Also wallet fixes, refactoring, etc. I expect we'll see mostly that up to mainnet, the only other main thing to get there is Cuckaroo, our second PoW.
+
+### 1. Agenda review
+[Proposed agenda](https://github.com/mimblewimble/grin-pm/issues/12) accepted, with an added point of "Wallet plugins", and moving POW to earlier in discussion.
+
+### 2. Action point follow-up
+* P2P tx building: No update
+
+### 3. Wallet plugins
+* mcdallas tool [Gringotts](https://github.com/mcdallas/gringotts-rust) keybase integration for tx building triggered thinking on supporting "transaction plugins" in the wallet, where http/s could be one such plugin, file-based could be one, gringotts could be another, etc.
+* _yeastplume:_  'plugins' just means providing standard API entry points for different communication methods.
+* _antiochp:_ might be best to get two or three impls done manually so we know what shape the plugins will likely be.
+   * _yeastplume:_ I think getting the http and keybase 'plugins' together in a common format would go a long way towards shaping that.
+* Things worth adding:
+   * from/to in the JSON exchange format as well, to help normalize drop-off services like grinbox
+   * a TTL expressed in block height
+ * Open call to all people building wallet and transaction-building services to get  involved and shape this!
+
+### 4. POW
+* _tromp:_ I've been discussing cuckatoo32 feasibility with an asic designer, they say it looks impossible to make it run at 1 gps. So will start a discussion thread on forum (ed.note: [here](https://www.grin-forum.org/t/cuckatoo32-feasibility/1199)), about required memory bandwidth and how to achieve that. 
+* Anything <1 gps affects progress-freeness.
+* Tromp working on Cuckaroo coding.
+* Discussion around primary vs secondary POW terminology. Alternatives suggested: 
+   * ar/af
+   * GPU/ASIC
+   * mean/lean
+   * cuckaroo/cuckatoo
+   * ari/afi
+ * Decision to keep naming as is for now and change in the code once there's consistency.  
+
+### 5. Hard fork
+* With POW not ready it's too early to agree on a HF schedule.
+* Decision to review again next week. 
+* HF Contents will mainly be Cuckaroo POW.
+
+### 6. Mainnet planning
+* _ignopeverell:_ We're getting real close, if it was a normal software product, I'd be thinking about releasing already
+* Mainnet milestone: https://github.com/mimblewimble/grin/milestone/4
+* Igno to do another pass on triage of `must-have` for mainnet issues. 
+
+
+### 7. Other questions
+
+* Need to introduce a 'block size soft limit', i.e. a capacity limit to allow a miner to ignore txs exceeding the soft block limit. Purpose to allow miners to be able to mine smaller blocks than consensus value for economic/orphan related reasons, and prevent tx spam when fees are very low.
