Australians win the New York Consensus Hackathon

At the New York Consensus event, a bunch of Australians banded together and entered the hackathon.  Playing on the Australian them of the black box flight recorder, the team created an Ethereum based “block box” event recorder, to record traffic incidents using Ethereum, Microsoft Azure, Microsoft Power BI and IoT hub.  The winning team included:

  • Tim Bass form Block8
  • Nick Addision from Agri Digital
  • Lucas Cullen from Civic Ledger
  • Sam Brooks from Veredictum

Special thanks to Mark Staples from Data61 for his input.  Sam’s original white paper and hackathon code can be found here.

2017 APAC Blockchain Conference Sydney, Australia

The APAC Blockchain Conference, developed in partnership with the Australian Digital Currency Commerce Association (ADCCA) and the Blockchain Association of Australia, took place from 7-9 March 2017 in Sydney, and focused on identifying the opportunities and overcoming the challenges to make the revolutionary blockchain technology a reality.

The event looked beyond the hype by bringing together captains of industry who are currently driving the change, world leading projects, innovative start-ups and regulators all into one place to share their knowledge and experiences.

Lucas was invited to participate in the APAC Blockchain Conference program to share with the delegates Civic Ledger’s journey, the problems we are solving with the technology and where Civic Ledger will be in 2017 and beyond.

Sheree was also invited to give a legal perspective on blockchain developments  but couldn’t not attend.

Lucas shared the stage with Emma Weston, CEO and Co-Founder of Agridigital, a provider of blockchain solutions that brings transparency, efficiency, and trust to agri-commodity supply chain, and Julian Smith, CEO and Founder of Blockfreight, the blockchain for global freight.

Photos from the UQ Bitcoin event

On Tuesday 21st Feb, I was asked to panel a screening of the documentary “Bitcoin; The end of money as we know it” at the University of Queensland. A quote from one of the guests.

“I thoroughly enjoyed your talk about bitcoin last night at the University of Queensland.

I started researching the currency from a legal perspective about two years ago and wrote a blog on my findings. I would like to retract my blog and write a new analysis of the currency after hearing your talk”

Here are some photos from that event.

Australian Bitcoin Pizza Day events

On this day bitcoiners all the world over will celebrate the anniversary of the most expensive pizzas in history.

Bought on 22nd May 2010 programmer, Laszlo Hanyecz, paid a fellow Bitcoin Talk forum user 10,000 BTC for two Papa John’s pizzas. Back then – when the technology was just over a year old – that equated to roughly $25, but is $5.12m by today’s exchange rate.

At bitcoin’s all-time high, the pizzas would have been worth an eye-watering $11.47M, making them likely candidates for the most expensive pizzas of all time.

Now widely recognised as the first real-world transaction with bitcoin, May 22nd has come to celebrate ‘Bitcoin Pizza Day’, with cryptocurrency enthusiasts raising a slice to Hanyecz’s infamous hunger pangs that paved the way for early merchant adoption.

Come and celebrate Bitcoin Pizza Day.

Node Update

To “vote” on the blockchain scaling debate, I personally have changed my full node to Bitcoin Classic from Bitcoin Core.

I won’t go into the scaling debate here, but long story short the bitcoin blockchain has a 1mb limit per block.  The bitcoin community have not reached consensus on which of the proposals is the “correct” solution.  Ultimately, its up to the community to vote, and we do that by running the client that implements the solution we think should be the future of bitcoin.

The Blockchain Association of Australia, run a full node on Microsoft’s Azure cloud service as a way to contribute back to the community, and ensure there are enough full nodes on the network to propagate and validate transactions.  At the moment, this is bitcoin core client.  I will put it to the board for a vote to change this to classic.

June 2016 Bitcoin Halving is Near!

The halving is near!

For those who are new to bitcoin or need a refresher, bitcoin “halving” occurs about every 4 years. This was built in to the protocol to reduce the supply of bitcoins over time, arguably to make bitcoin more scarce. When miners find a block, about every 10 mins, they are paid 25BTC for their efforts. Around the 10th of July this reward is set to halve to 12.5.

Please see the meetup board for your nearest halving party.

Our node is running well. We recently upgraded it to core 0.12.1. At one point we had over 100 connections to it!

The colour coin membership development is still ticking along. We have setup our NodeJS endpoint to automate this process.

A slack channel has also been setup to engage with the community. Visit at:

Lucas has been busy preparing for the Block Chain summit in Melbourne. Unfortunately Adam could not make this event, due to his recent commitment to run for Senate with in Tasmania. This will be a great way to promote the BAA. Note: All flights and accommodation have been paid by the attendee themselves.

As mentioned above, one of our founding members, Max Kaye has recently registered his party VOTEFLUX.ORG | UPGRADE DEMOCRACY! and is fielding candidates in all states at this Federal Election. Adam has been selected as the Tasmanian candidate and is running alongside Max in their effort to gain at least one senate seat.
If elected, a Flux senator promises to vote according to the will of the Flux members as expressed via the Flux App. More info at
