Substrate/FRAME
the big repo reorg
towards 2.0
/client
/frame
/primitives
the outer node infrastructure
the inner chain functionality
the interface between the two
primitives
- interface between inner and outer node
- prefixed `sp-`
Terms
client
- the outer node infrastructure
- prefixed `sc-`
FRAME
- our opinionated modular, infrastructure to build chain logic
- prefixed `frame-`
pallets
- optional modules for FRAME
- prefixed `pallet-`
Upgrade.txt
with the release of 2.0
- publishing on crates.io
- full Semantic Versioning for all crates
though some (e.g. networking, consensus) will be < 1.0 -
docs/Upgrade.txt will record all steps necessary to upgrade to latest version
continuously updated, also on master
Does it mean it's stable?
It's complicated.
- We are building on it: Kusama
- You don't need build against master for the latest changes
- It's on crates.io; Semantic Versioning; release notes
Should you build on it?
Does it mean it's stable?
– YES
It's complicated.
"Already know about potentially breaking changes" –like what?
- Long running offchain workers
- On-chain data migration paths
- Reducing the macro-magic
- Networking, consensus
consensus
consensus
is this the future yet?
let's give it a reality check

PoC: Gather.wtf
hackathon project–a meetup replacement on substrate with:
- global registry of groups & events
- on-chain governance (awesome!)
- email+pw-login (translates to Account-keys)
- email-auth-flow via json_rpc
- notification-emails via Offchain Workers
- offchain metadata through IPFS
more in the blog post
Interoperability
Safe Data Storage
Data Privacy
Gather.wtf is still lacks ...
what's Parity doing about it?
Interoperability
Polkadot
- parachain
- parathreads
- XCMP
Bridges
Offchain-Worker
- substrate2substrate
- substrate2X
- SPREE
connecting to the non-chain-world, e.g.:
- email or push notifications
- external login mechanism
Large File Storage
- Extension to Substrate & FRAME (in research)
- Storing & retrieving non-consensus off-chain data easy (and native to) in Substrate
- Have a "native" reference to off-chain data on-chain
make Substrate "understand" offchain data - Piggy-back on existing Substrate network to distribute the data
- Allow for data validation to ensure safety-at-write
Data Privacy & Security
- Zero Knowledge Proofs in Substrate
maybe some ZEXE, ZK-Rollup/ZK-Sync - Multi-Sign/ Threshold-Schemes for Offchain Work
- QUIC support for libp2p
- Substrate SecretStore
- Trusted Compute execution
and so many more...
what will YOU make the future to be?
thanks!

Behold the future is upon us!
A quick recap of what happened at Sub0.1, some more projects and honorable mentions, we didn't have time for and other changes that happened and a quick reality check and view into the future of Substrate.
