Closed Fatman13 closed 1 year ago
Hi @Fatman13, thank you for your proposal. We will not be proceeding with this grant at this time as it does not align with the priorities of our current research & development roadmap. Wishing you the best of luck with your project work!
Hello, @ErinOCon! Thank you for the reply! Would you please kindly share a list of current priorities? Would love to align our goals with Filecoin's research & development roadmap. Thank you!
@ErinOCon btw do you have an account on Slack? Maybe we can have a quick chat on Slack too.
There are currently more than 1200+ nodes on the network that is larger than 3PiB power, which means it is likely that the node will have at least one partition to prove for each deadline of the day. Falling out of sync and failing proof would mean devastating loss for SPs.
With the introduction of https://github.com/filecoin-project/FIPs/discussions/386, it would make stakes in the node up to 100x higher, which in turn making potential loss/penalty also up to 100x. Therefore we think that chain-co could be a crucial piece of infrastructure to keep the network going forward.
HI @Fatman13, thanks for reaching out! I have provide resources on the grants-help channel in Slack!
Fuhon is no longer being maintained and does not sync mainnet.
I have a couple Q on this proposal (not sure whats the status on this one given its closed)
Hi, @jennijuju, thanks for the reply!
Fuhon is no longer being maintained and does not sync mainnet.
Sorry to hear that. 😢
who runs the chain-co? SP themselves or some service providers?
For Lotus, it will be SP themselves. For Venus, it can be a chain service operator (a trusted third party).
whats the main difference between Venus node & lotus node today? AFAIK, majority of the protocol changes were made in lotus and back ported to Venus, does Venus normally then do a round of audit or optimization,
There are many subtle differences but the general consensus protocol should be followed by both. For example, Venus experienced this consensus issue earlier this year.
There is currently one audit report conducted for Venus.
so that if something bad occurs with lotus node -> the same wont happen to Venus nodes?
Right now given the market share, even if "something bad occurs with lotus node", the consensus of the network will still be of what Lotus considers to be true as Lotus is the overwhelming majority.
Pool of chain-co daemon nodes can be deployed across different geo regions to gain best chain synchronization from block propagation.
im highly interested in interchangeability between go impls & forest nodes!!
Maybe we can reorganize our proposal around this if that's what you consider to be most helpful to the network? We can cut couple things that may not be as important and revise the proposal to align with the long term goals of the network.
Hello, @realChainLife, glad chatting with you yesterday!
We have made modifications to our proposal for your revision.
lotus is planning to implement it natively for our users FYI - so not sure what an external service will bring.

There are a lot of things lotus could be planning, but features like PoST worker in the past the community had been waiting for close to a year for it to be implemented in lotus. I think this proposal doesn't necessarily conflicts with what lotus is planning, besides the approach we take is fundamentally different where our solution opens up collaboration with all potential Filecoin implementations. Overall, I think both approaches can be complementing each other to have a more secure network.
Sure - I’m just sharing information as an ongoing wip lotus issue is being referenced. And I wanna make sure lotus users who read this message knows that we are implementing a native solution, and they can decide whether they should plan for an external service in their architecture or not.
Looking forward ti Venus to implement a solution for Venus user and broader community even sooner.
I think this proposal doesn't necessarily conflicts
to be clear, I have never implied there is a conflict. in fact - I reached out to the grant team when I noticed this RFP was closed, cuz I do think it needs better scope but has interesting points.
Hi @Fatman13, thank you for your patience with our review. We expect to have an update available next week.
Hi @Fatman13, Thank you again for your patience with our review process. After additional evaluation, we will not award funding for the scope of work outlined here. We would be happy to consider a new proposal with value for the broader Filecoin ecosystem.
Got it! Thanks for taking time to revaluate the application!
RFP Proposal:
A high availability solution for Filecoin Daemon
Name of Project: Chain-co
Proposal Category:
core-dev

Force community Team
(Optional) Technical Sponsor: N/A

Project Description
At the time of writting this proposal, Filecoin network has reached ~17 EiB storage power with ~20 to ~30 PiB growth per day. Given that more than 400 nodes are having 10+ PiB of storage power with top nodes even having 100+ PiB storage power, a high availability solution for Filecoin daemon would be crucial to the stability and overall health of the network. Imagine the Filecoin daemon node for a 100 PiB storage system failed to sync height with network or experienced severe hardware failure for an extended period of time, storage power would be wiped out and causing turbulence to the network, which is not ideal at all.
In order to mitigate the risk of Filecoin daemon failure and to secure a generally sane and coherent network, we propose chain coordinator, chain-co for short, to coordinate a collection of redundant daemon nodes and let the storage system to use the daemon that has the heaviest chain (most weighed). Thus, paves the way for a stronger and more resilient Filecoin network.
Value
The benefits of chain-co to the long-term health of Filecoin infrastructure is profound. For storage providers, they can now rest assure that there wouldn’t be a single point of failure for their storage systems. For ecosystem partners, they can now build upon a more reliable infrastructure for their applications. For end storage user, they can also enjoy a more consistent storage service without denials. Imagine an ideal world that each of the four filecoin implementation represents 25% of the network and chain-co have a collection redundancy daemons of the four implementations. In case when one implementation fails to sync, chain-co solution could help to make sure that the Filecoin network wouldn’t suffer denial of service.
On the other hand, the risk of not having chain-co infrastructure would deprive storage providers, ecosystem partners and end storage user the exact benefits described above, which also represent a systemic risk that the whole Filecoin network come into a halt if one implementation of the Filecoin fail to sync.
Deliverables
Chain-co solution will be running in between a pool of redundant Fileccoin daemons of different flavors and a proxy agent. Essentially, the complete chain-co solution will be replacing single daemon solution to make sure that your storage systems have access to all the critical RPC APIs you need for PoRep and PoST.
