The Indexer Ecosystem Collaboration call is an opportunity for Tezos Indexer developers to collaborate and develop a shared understanding of Indexer challenges.

# Agenda / Topics 1st Nov, 2022. 16:30 CET / 07:30 Pacific (45 minutes)

proto-ecosystem calls.

Lima
Two

Corentin - Suggests having regular calls, not ad-hoc.

# Agenda / Topics 26th July, 2022. 16:30 CET / 07:30 Pacific (45 minutes)

- K new ops
- VDF op
- paid storage
- Kathmandunet will be reactivated, because TORU was disabled in error.
- K on testnet will have soru disabled, to match presumptive K protocol on mainnet.
-
- Events

Nicolas; First five cycles on L will not have VDF.
VDF has a bug, but it is expected to be fixed in the shell, and will run in K.
If a baker does not reveal in two hours, they lose their VDF fee.

- [ ] Question for Alex/TZStats, are they doing some sort of calculations for baking rights, or relying on RPC?
- [ ] Cycle parameter is deprecated in K. Let's track indexer progress on this, so Octez can know when it is safe to remove.
- [ ] Get block levels for example new ops on K.

# Agenda / Topics 12th June, 2022. 16:30 CET / 07:30 Pacific (45 minutes)

- Kathmandu
- vdf_revelation
- events
- MZ- decoding typed events into a human readable manners.
- Indexers that have active Ghostnet instances - Status?
- [x] http://ghostnet.tzkt.io/ - done, happy about this
- [x] http://ghost.tzstats.com/ - Updated, some quirks on baker rights. It's running
- [ ] Conseil (which web interfaces are out there now?). In progress, some issues with nodes.
- [ ] Tezos Indexer - easier
- [ ] Functori - Lightweight explorer for devs.
- Indexers that have active K instances - Status?
- [ ] http://kathmandunet.tzkt.io/ - pretty hard to get to this.
- [ ] http://kathmandu.tzstats.com/ No time this month, probably end of August
- [ ] Conseil - On way, but having to catch up on Tech debt related to J.
- [ ] Tezos Indexer - ocaml changes that make it more complex for tezos indexer.
- [ ] Functori -

Vishakh - nodes had some problems. 70G on ithacanet. Why is it so big? - Nicolas Answer; NL did stress testing, which created a lot of accounts.
Fedor - Do end user require this type of data?
- Testnet bloat - Our faucets are open, and can or will become a problem
- Simon TezTok.
- New ops - important that we get these ops on testnets early on.
- Alex - read spec. Seems to be missing the type of an event, we get the value in the receipt.

# Agenda / Topics 5th April, 2022. 16:30 CET / 07:30 Pacific (45 minutes)

- Guest Joel Bjorson from Trilitech. Joel will be joining us to talk about Tickets generally and changes to Tickets in the upcoming "J" protocol

# Agenda / Topics 22nd Feburary, 2022. 16:30 CET / 07:30 Pacific (45 minutes)

### Topics for discussion

- Ithaca support
- What are the URLs for each indexers ithaca instance?
- ETA for getting ithaca indexers online for each team?
- Impediments / Blockers?
- Sapling
- There is a fresh effort to build out Sapling support in the Tezos Wallets.
- What implications will Sapling have on Indexers?

## Agenda / Topics 25th January, 2022. 16:30 CET / 07:30 Pacific (45 minutes)

### Notes

- Non-indexer specific, some public nodes do not expose the POST RPC `/chains/main/blocks/head/context/contracts/{address}/script/normalized`
- Ithaca delay
- Silver lining for tooling teams is more time to implement/integrate or pay down tech debt where we often don't have time

## Agenda / Topics: 11th January, 2022. 16:30 CET / 07:30 Pacific (45 minutes)

- Mondaynet
- Tenderbake

### Notes

- Mondaynet discussion
- Tradeoff between faster moving target, early testing and the maintenance cost of continious integration against mondaynet
- Ithaca integration in indexers
- Teams have conducted or are conducting planning and impact analysis. No significant progress on implementing support.
- Discussion on capacity planning, operationl expenses, and strategies for reducting storage costs
- Discussion on IPFS, the cost and performance challanges, CloudFlares service (good but very expensive).
- Discussion on community incentivized IPFS cluster

- Ad-hoc survery of atendees about experience with testnets
- There are concerns about the longterm operationl cost in maintaining such long-running testnets
- Re-deployment of smart-contracts on testnets is seen as a chore.
- Protocol Injection - wishes from Indexer teams to ease development and maintenance of indexers
- Earlier notice of injection, and earlier opportunities to integrate (We did have idiazabalnet this time)
- Earlier access to Changelogs/Backlog.

### Agenda / Topics (December 14th, 2021)

- Survey teams on their experiences with Tezos testnet and their lifecycle
- Tenderbake progress / challanges

### Agenda / Topics (November 30th, 2021)

Theme: Tenderbake and Indexing

### Guests

- Vbot
- EugenZ

### Items

- Tenderbake and the implications for Indexers
- Change in Endorsement slots 256 -> 7,000
- New convenience RPCs to fetch rights
- Discuss performance implications, steady-state and modes of degradation
- Is it i/O bound and synchronous?
- Discuss how to calculate locally (vbot to elaborate)
- Endorsement forecast design (Rights Heatmap)
- Does the heat map, as a feature, provide value to users when using tenderbake?
- Endorsement rights are going to be far more abundant.
- Re-orgs
- What are the characteristics of re-orgs in Tenderbake?
- There was a discussion that a client of the mempool can determine if a block will be final (earlier or before the next block) based on the number of pre-endorsements in the mempool. This is based not on the number of endorsements but "endorsing power." Let's discuss or try to get specific details on how this works.
