Proof of work is not a consensus model, it's a method to elect a block author, an incentive mechanism designed to keep miners honest.

Consensus is the process through which the network agrees on state. Examples are Nakamoto consensus (e.g. Bitcoin), BFT (e.g. Tendermind) or GRANDPA+BABE (Polkadot).

Fractal Blockchain | Porto, Berlin or remote | https://trustfractal.com/

Fractal builds compliance and identity products for the web and blockchain. We're already ahead of Telegram and Coinbase in identity provisioning and verification.

We're looking for ridiculously good senior engineers. The unicorn candidate will know full-stack web, AWS infra (docker/terraform for Fargate/ECS) and have blockchain familiarity. We work mostly with Ruby/Rails, JavaScript/React, and Go. Amazing engineering team full of A-players.

You can see a quick brief of what we're looking for here: http://drop.whoisjuliosantos.com/ik9Y1z

If you see yourself in this brief, we should talk! I'm the CTO: julio@frctls.com

I published a code walkthrough tutorial yesterday on this: https://hackernoon.com/full-stack-smart-contract-development...

OP here, happy to answer any questions.

SEEKING WORK - remote only, happy to fly if need be though

6 years Ruby on Rails and Javascript (vanilla, Angular, Backbone) experience.

Co-founded 2 companies as CTO: https://gruvi.tv and https://www.madmarkedet.dk/. They're now on cruise mode so I'll spend 2016 freelancing.

We built http://www.attmatr.com with a similar philosophy. The difference is we strive to actually be farm-to-table as we deliver to the customer's doorstep - and our platform caters to B2B too. We're only in Denmark at the moment but will soon expand abroad.

Apologies, I haven't made myself clear with that idiotic of a snarky remark :) What I meant is that their actions in the past shouldn't be an excuse to their actions today.

The principles behind PageRank are based on unbiased reputation, and provide for a good ranking system (spammers aside). Whatever's thrown on top needs to be carefully considered not to enforce biases towards any group in particular.

SEEKING WORK — Remote — max 10h/week — Berlin, Germany

My primary expertise is full-stack development and deployment with Ruby on Rails and JavaScript. I have programmed professionally for 9 years, and have 3+ years of professional experience with Ruby on Rails.

I hold a Masters in Informatics and Computing Engineering. Currently, I live in Berlin, where I lead the development team at Gruvi, the start-up I co-founded.

At Gruvi, I have developed, and managed the development, of several small- and large-scale web/mobile applications. Last year alone our products handled millions of visitors globally for the likes of Warner Brothers, Sony Pictures International, and Disney. I lead our development process using Scrum and manage developers both locally and in outsourcing positions in Latvia and Portugal.

I am also a great cook.

Yea, we're all pretty sane over here.

It's not arbitrary. Check out http://en.wikipedia.org/wiki/Decimal

I believe the correct term is Winklevi.

I recommend you read the article first. Check out the ROI section: http://www.gwern.net/Melatonin#roi

Then, £400 a day is pretty standard for London? I frequently get offers under that value, hence my belief that this kind of pay doesn't come through normal channels.

Edit: Wrote this before coffee. Thought we were talking hourly rates. Nevermind.

Any tips you can share on how you achieved that position?

That's still in Beta though.

Well, it may not be their fault: http://status.aws.amazon.com/

I still dream of the day they'll let us set up different availability zones. Not that I'm sure this wouldn't occur, mind you.

It doesn't affect it in any way: http://facebook.stackoverflow.com/a/12203207/214773

Take a chill pill. «So, what do you do?» is a conversation starter, not an irreversible linnaean damnation.
