Faster dapps with the robustness of the Ethereum

Transcript

1. Faster dapps with the robustness of Ethereum Cryptoeconomics Lab -Sg
2. Slow dapps • Gas existence • Gas Price Pump • Confirmation
3. Robustness of Ethereum Buy GPU mining farms only for a few moments
4. Insecurity of normal sidechains In detail: https://speakerdeck.com/shogochiai/2nd-layer-scaling-and-economic-security-analysis Implicitly trusts the malicious operater (e.g. Federated withdrawal, Proof-of-Burn)
5. Security inheritance of Plasma In detail: https://learnplasma.org Deposit withdrawal process doesn’t require to talk with operator. 1st layer contract do all. No trusted point.
6. Permissioned chain or federated bridge *without regulation/license* — cannot store values because of incentive to steal money Collude to achive big double spending Don’t permit to withdraw
7. Build an app on Plasma Imagine RoR and Heroku Imagine BaaS with Modern UI Imagine stressless dapps!
8. Poker on Plasma Cash 
 with
 Range Chunking
 RSA Accumulator
 
 FYI
 UTXO Contract with multisig commit-reveal
9. Plasma Generator
10. Why gather them all into one place? Cheap submission cost by the commit aggregation Fast Finality’s logic and “insurance” fund had better to be shared (unless the chain’s contract is broken) The opeartor delegation with legal contract and SLA
11. Why gather them all into one place? - 2 Network Effect The same interface Plasmas there will be. UTXO based contract would be shared on github Even though a papp(Plasma app) failed in a certain country, it maybe used in a certain other countries. (Imagine Uber, Airbnb, and so on.)
12. How can we write UTXO contract? Look, Ivy lang Dan Robinson from Chain Inc. invented Ivy-lang contract-clause syntax is like contract-function in Solidity The constructor makes input of Tx, then clause get args to process data, finally output would be released.
13. Challenges • Ivy doesn’t cover strong typing, we need it for deal with complexity of UTXO contract on Plasma. • Fast Finality and Commit Aggregation is still early stage of research • Pros/Cons comparison with the “counterfactual on Plasma Cash” idea.
14. Waiting for… • Serenity(Sharding) makes the “commit“ cost much more cheaper. • Much more insight of UTXO based contracts’ safe exit procedure (like Plasma Cashflow’s swap Tx). • Much more participation of engineers from the country suffering from unstable goverment ;)
