From Snowflake to Avalanche: A New Family of Consensus Protocols to Change the World Professor Emin Gun Sirer of Cornell University: Cornell professor Emin Gun Sirer will unveil, for the first time in Europe, a new family of consensus protocols that combines the best of Nakamoto consensus with the best of classical consensus. One of the earliest pioneers in the cryptocurrencies space explores where this journey might take us next.

Interessanter Komentar:
This "Avalanche Consensus" is not fundamentally novel! It is inherently the same concept with NKN.ORG 's majority voting cellular automata (MVCA) consensus. The reason why I claimed that was we verified the concept both proof in math and simulations last year, we finalized the whitepaper in Feb 2018, and now we have released the minimum viable prototype (MVP) of NKN blockchain already (released on 6/16/2018, NEO London Meetup).

Kennt jemand NKN?
Ich habe das WP (https://www.nkn.org/doc/NKN_Whitepaper.pdf) überflogen, und es sieht interessant aus.
Ich glaube ich werde mir da ein paar Krümel holen...

90 minütiges, englisches Interview mit Gün sehr hörenswert! Kleiner Geschichtsausflug mit guten Vergleichen und Erklärungen.

Episode 23
September 19, 2018 — 90 mins
Guests: Emin Gün Sirer

Revolutionary! On this episode we have the brilliant Dr. Gün Sirer to whet our appetites for Avalanche, a new category of consensus protocol. He distinguishes Avalanche from Paxos/RAFT systems, blockchain, and traditional gossip networks to show how this new algorithm prevents double spends while allowing for high throughput (early tests supporting over 1200 tx/s). We learn about his new coin, Ava, which will test the limits of Avalanche’s public consensus on a global scale! The future is exciting!

und noch eine weiterer Artikel der beschreibt, warum PoW, PoS und DAG keine Konsens Protokolle sind. Für mich hat es den Anschein, als würden wir den nächsten wichtigen Schritt in der Entwicklung angehen...

Quote

PoW, PoS and DAGs are NOT consensus protocols
The much hyped concepts of Proof-Of-Work, Proof-of-Stake and Directed Acyclic Graphs are often mistakenly advertised as “consensus protocols”. Neither of them are, but rather address the key challenges of a robust blockchain design: Sybil resistance and asynchronicity.

so mal wieder etwas zum Thema. In dem Artikel wird versucht, den Mechanismus verständlich zu vermitteln...

Der Artikel beschreibt zum besseren Verständnis anfänglich die grundlegenden Probleme und Technik, sowie deren Entwicklung.
Nach der Einleitung und der Beschreibung der Entwicklung der Techniken, wird beschrieben, wie Avalance "das Beste aus zwei Welten" vereint.
Im Artikel sind auch Bilder/Animationen.

Avalanche

Avalanche comes in and combines the best of both world’s, in particular,

Quick finality and low latency: That is, it takes around 2 seconds to achieve finality across the globe. This basically means that after 2 seconds, you can get your payment processed and verified.
Higher throughput: 1000–10,000 transactions per second.
Robust: The network does not need to agree on who the participants are to achieve undeniable consensus.
Quiescent protocol: Most importantly, the protocol is green. That means that it is sustainable, it does not waste any energy, and that there is no special ecosystem of miners with their own separate interests from the users.

In this article, we will simplify and visualize the protocol for you, leaving you with an understanding of this new approach.

Ferner werden erklärt:
metastability
Protokoll anmerkungen
Efficient scalabil
Byzantine tolerance
Egalitarian ecosystem
No liveness guarantee for conflicting transactions

The Avalanche Token: AVA
Sybil deterrence via staking
Economic governance via voting

Conclusion

People often talk about the consensus protocol used in Bitcoin as if it was a pure decentralized approach that determines the opinions of all network participants equally. Unfortunately it is not, in Bitcoin the decisions are mostly made by the miners.

In contrast, Avalanche separates the consensus problem from the governance problem. Each one is tackled modularly and independently. Consensus is achieved via a smart combination of gossip protocols with recurrent subsampling. While, fair governance is achieved via sampling and staking resulting in a direct tie between users and their decisions.

ich packe mal noch ein 15 Minuten Video von Emin Gün Sirer rein, in welchem er über Snowflake und Avalanche spricht.

Das Thema scheint langsam an Interesse zu gewinnen

Hi everyone, Humbled and thrilled by the attention Avalanche is getting. Our unofficial telegram group went from 25 enthusiasts to, literally, over 9000 overnight. I'm going to be doing a development binge. Please bear with me as I ignore everyone for a short while.

Very promising new consensus algorithm. Maybe it will take some time until we see an implementation.

Thank you For your Feedback! Maybe you would like to drop a Post if there are any news. I am very exited and interessted about and in this.

I‘ll try to do my best. No easy to keep updated in crypto space.

Von der Schneeflocke zur Lawine, aber hoffentlich kein Schneeballsystem im deutschen Sinne Grin

Cornell University professor Emin Gün Sirer schwärmt seit ein paar Wochen von der neuen Protokoll Familie. Er ist eine bekannte Größe im Blockchain Ecosystem und was ich bisher von ihm gelesen habe fand ich gut (kritisch und sachlich).

Das neue "Pokomon" whitepaper von "Team Rocket" hört sich echt spannend an (ich konnte nicht widerstehen Roll Eyes

), hat sich schon jemand damit auseinander gesetzt, gibt's schon Meinungen dazu? Falls jemandem ein Projekt mit dem consens Protokoll über den Weg läuft wäre ich für nen Hinweis sehr dankbar, aber vermutlich wird das noch ne ganze Weile dauern bis da was kommt.

Soweit ich das verstehe, werden mehrere Protokolle ineinander verschachtelt und darauf basierend weiter aufgebaut. So wird anfänglich das Slush Protokoll in einem Netzwerk mit byzantinischen Nodes ohne Fehlertoleranz integriert. Darauf basierend erweitert "Snowflake" Slush mit einem einfachen Zähler, welcher die "Stärke/Kraft" der Node speichert. Durch entsprechende Parametrisierung wird dann eine Fehlertoleranz erzeugt (glaube ich verstanden zu haben Grin

). Dann fügt "Snowball" vertrauen hinzu. Und hier bin ich technisch dann ausgestiegen Roll Eyes

Zwar kann ich dem englischen noch einigermaßen folgen, aber sinnvoll, lesbar übersetzt bekomme ich es dann nicht mehr, von den Formeln im WP ganz zu schweigen Tongue

Quote

Snowball augments Snowflake with confidence counters that capture the number of queries that have yielded a threshold result for their corresponding color (Figure 3).
A node decides a color if, during a certain number of consecutive queries, its con-fidence for that color exceeds that of other colors. The differences between Snow-flake
and Snowball are as follows:
1. Upon every successful query, the node increments its
confidence counter for that color.
2. A node switches colors when the confidence in its
current color becomes lower than the confidence value of
the new color.

Danach wir mit Avalanche DAG eingeführt.
Mit Avalanche wird das letzte Protokoll eingeführt, es generalisiert Snowball und wartet die dynamischen "append-only" Directed Acyclic Graph (DAG) aller bekannten Transaktionen.

Quote

The DAG has a single sink that is the genesis vertex.

Hier hat google Translate nciht wirklich weitergeholen ="Die DAG hat eine einzige Senke, die der Genesscheitel ist" Grin

Und meine Übersetzung hiervon erspare ich euch auch besser....

Quote

Maintaining a DAG provides two significant benefits. First, it improves effi-ciency, because a single vote on a DAG vertex implicitly votes for all transactions on the path to the genesis vertex.
Second, it also improves security, because the DAG intertwines the fate of transac-tions, similar to the Bitcoin blockchain. This renders past decisions difficult to undo without the approval of correct nodes.
