Scaling blockchain: The final frontier

Blockchain technology’s potential has been much publicised. However, there remain significant obstacles to be overcome before it achieves widespread adoption.

The most pressing question to be answered is whether or not it can scale-in terms of both total transaction volume and the number of independent participants involved in processing them.

A wide variety of solutions have been proposed. These fall into two categories — layer I ‘on-chain' solutions, such as Ethereum’s effort to implement sharding, or layer II solutions built on top of the blockchain ‘off-chain', such as the Lightning Network.

How feasible are these solutions? Are these just short-term fixes? What are the fundamental tradeoffs? What can we expect in the future?

What you’ll master



This 2-day workshop saw 20 of the world’s foremost developers, researchers and industry experts lead discussion on a variety of scaling solutions for blockchain.

Highlights included:

  • DAG-based cryptocurrency frameworks
  • Consistency guarantees of different blockchain algorithms and their relation to scalability concerns
  • OmniLedger: A secure, scale-out, decentralised ledger via sharding
  • PolyShard: How coded sharding achieves linearly scaling efficiency and security simultaneously

This workshop is the second in our series of 2-day Master Workshops examining scaling solutions for blockchain. It followed our ‘Off the chain' event earlier in the year, where 25+ experts including Patrick McCorry, Liam Horne, Jason Teutsch and Lefteris Karapetsas joined us in Berlin.


What they said about Master Workshop: Off the chain:

We should have more events like this … where we can all talk together and discuss our solutions and how we can combine our work.
Lefteris Karapetsas, Raiden Network Developer Team Lead

I feel like there’s a lot of diversity here and you really get an idea of what the latest is in the space. It’s been a really good day for me.
Jason Teutsch, Founder of TrueBit
