About

• Blockchain and full-stack software engineer

  • Worked with Port of Rotterdam as senior engineer, where I met Mick

What sucks about mainnet?

• Transaction fees
• Storing lots of data
  • $$$
  • images?
  • HTML? 
• Speed
  • Moving lots of data 
• Various other constraints of public chains
  • Privacy (in proprietary/business settings)

But mainet is also great.

What is the alternative?

• Polkadot
  • not ready till Q3
  • requires stake/approval (not for MVP's)
• Cosmos
  •  IBC not ready till Q3
• Plasma
  • "WTF are predicates."
• POA/xDAI
  • Trusted validator set
  • No bridging to mainnet.
• None of these are ready

We'll launch our own blockchain!

But wait, take this...

Berse.

The bridge between chains.

Ethereum Mainnet, Kovan, Rinkeby, Polkadot, Cosmos...

Berse: how it works

• Contracts emit events (as usual)
• You write your contracts, deploy them to two chains
  • Mainnet
  • Your own chain
• Using Berse's API's, you can verify the events of one contract on the other chain

Berse: technicals

• Cross-chain relayer of events
• Simple one-liner Solidity API:
  • EventEmitter.relayEvent("Deposit")
  • EventListener.checkEvent(fromChain, proof)
• Merkle proofs to verify events on other chains
• Tunable security parameters around finality/delay

Demo

Cheers!
