19:30-20:45 - Breaking free from chains: Secure "chainless" protocols for Bitcoin (Aviv Zohar)
20:45-21:30 - Free discussion
Bitcoin and other blockchain-based crypto-currencies do not easily scale to process a high throughput of transactions, or to quickly approve individual transactions. When block creation rates and block sizes are accelerated, networking delays cause many conflicts to occur and the security of the protocol quickly degrades.
We present a new "chainless'' protocol for the consensus core of crypto-currencies that remains secure even when delays are substantial. During the talk, we will present various attacks and naive attempts to solve them that slowly develop and lead to our current approach.
The talk will assume some very basic knowledge of the current Bitcoin protocol (proof-of-work & longest-chain selection).
The talk will be given in Hebrew.
We would like to start the lecture at 19:30 sharp, so please make an effort to arrive on time, taking traffic into account. From 19:00 you'll have the opportunity to enjoy refreshments and socialize.
As always, the talk will be recorded for those of us who can't attend.
Parking is recommended at the nearby Azrieli Center.
