Video & slides from #ETHBerlin: Introducing OpenST Mosaic Protocol: Running meta blockchains on Ethereum to scale DApps to billions of users

Mosaic is token sharding at layer 2 that will work right now on Ethereum v1.0 to scale DApps — with an open, staked validator set, and asynchronous finalization of transactions on Ethereum.

On Friday 7 September, 2018 OST Chief Blockchain Scientist Benjamin Bollen presented OpenST Mosaic Protocol for the first time at ETHBerlin.

ETHBerlin was a fantastic community-driven event featuring substantive tech talks, workshops, and an incredibly inspiring hackathon. Huge props to the ETHBerlin community leaders for your tireless efforts. You rocked it! That was one of the best developer events we’ve ever participated in!

ETH Berlin marked the public introduction of OpenST Mosaic — the first time we presented the OpenST Mosaic Protocol in full details.

  • OpenST Mosaic is a consensus protocol to run meta-blockchains on top of Ethereum.
  • Each meta-blockchain runs in parallel and injects an additional state space into Ethereum.
  • Each meta-blockchain is secured by Ethereum with an open, staked validator set.
  • All transactions on meta-blockchains are asynchronously finalised and committed onto Ethereum.
  • Mosaic has a message-passing protocol between Ethereum and meta-blockchains (later directly between meta-blockchains).

To put Mosaic into context vs. other important Ethereum scalability projects:

  • Sharding + Casper are the work behind “Ethereum 2.0” to scale Ethereum in the future (2020 to 2022), first by a hybrid POW/POS consensus mechanism, and then ultimately moving to a full POS consensus mechanism and sharding. Sharding is intended to provide parallel processing of transactions. Each node can process its shard separately, while together nodes can work in parallel, increasing the network’s bandwidth and transaction speed by several times.
  • Plasma is a body of work designed to scale each DApp off-chain. Plasma is a technique for off-chain transactions while relying on the underlying Ethereum blockchain to ground its security. Other off-chain scalability projects include state channels and Truebit.
  • OpenST Mosaic is a new on-chain layer 2 specification for token sharding — building on many of the concepts behind Casper and Sharding but enabling them to work now, on-chain, as a layer-2 solution.

Here is the video from Ben’s talk on OpenST Mosaic.

Here are the slides in-full from the presentation:

At the end of the presentation we present an update on the current state of OST and OpenST development, and what’s next.

  • OST KIT & OpenST 0.9.2 used by 120+ external developer teams on Testnet
  • OST KIT & OpenST 0.9.2 used by 10+ external partners on Mainnet3 months ahead of schedule
  • OpenST 0.9.3 (cross-chain messaging) completed
  • OpenST 0.9.4 (decentralized keys engine & token rules engine) in progress

We are currently introducing OpenST Mosaic at several events like ETHBerlin to solicit community feedback. Upcoming:

  • Upbit Developer Conference, in South Korea, on September 13th
  • Hashed Lounge: Origin Protocol & OST Simple Token on September 14th in Seoul

Q3 2018

  • Publish OpenST Mosaic Paper for Community Feedback

Q4 2018

  • Continue Mainnet testing of OST, OpenST Protocol

2019

  • Mosaic alpha
  • Mosaic beta — warm up validator pool
  • Widespread Deployments of OST, OpenST, Mosaic to mainstream businesses and DApps
  • smart contract calls across auxiliary chains
  • 2nd-order meta-blocks (aux-on-aux-on-ETHv1.0 or v2.0)

2020

  • Mosaic fully released to decentralised validator pool
