The Canada Council for the Arts, a digital strategy research report on blockchains and culture, and Vancouver (Canada)

Is the May 17, 2021 “Blockchains & Cultural Padlocks (BACP) Digital Strategy Research Report” discussing a hoped for future transformative experience? Given the report’s subtitle: “Towards a Digitally Cooperative Culture: Recommoning Land, Data and Objects,” and the various essays included in the 200 pp document, I say the answer is ‘yes’.

The report was launched by 221 A, a Vancouver (Canada)-based arts and culture organization and funded by the Canada Council for the Arts through their Digital Strategy Fund. Here’s more from the BACP report in the voice of its research leader, Jesse McKee,

… The blockchain is the openly readable and unalterable ledger technology, which is most broadly known for supporting such applications as bitcoin and other cryptocurrencies. This report documents the first research phase in a three-phased approach to establishing our digital strategy [emphasis mine], as we [emphasis mine] learn from the blockchain development communities. This initiative’s approach is an institutional one, not one that is interpreting the technology for individuals, artists and designers alone. The central concept of the blockchain is that exchanges of value need not rely on centralized authentication from institutions such as banks, credit cards or the state, and that this exchange of value is better programmed and tracked with metadata to support the virtues, goals and values of a particular network. This concept relies on a shared, decentralized and trustless ledger. “Trustless” in the blockchain community is an evolution of the term trust, shifting its signification as a contract usually held between individuals, managed and upheld by a centralized social institution, and redistributing it amongst the actors in a blockchain network who uphold the platform’s technical operational codes and can access ledgers of exchange. All parties involved in the system are then able to reach a consensus on what the canonical truth is regarding the holding and exchange of value within the system.

… [from page 6 of the report]

McKee manages to keep the report from floating away in a sea of utopian bliss with some cautionary notes. Still, as a writer I’m surprised he didn’t notice that ‘blockchain‘ which (in English) is supposed to ‘unlock padlocks’ poses a linguistic conundrum if nothing else.

This looks like an interesting report but it’s helpful to have some ‘critical theory’ jargon. That said, the bulk of the report is relatively accessible reading although some of the essays (at the end) from the artist-researchers are tough going.

One more thought, the report does present many exciting and transformative possibilities and I would dearly love to see much of this come to pass. I am more hesitant than McKee and his colleagues and that hesitation is beautifully described in an essay (The Vampire Problem: Illustrating the Paradox of Transformative Experience) first published September 3, 2017 by Maria Popova (originally published on Brain Pickings),

To be human is to suffer from a peculiar congenital blindness: On the precipice of any great change, we can see with terrifying clarity the familiar firm footing we stand to lose, but we fill the abyss of the unfamiliar before us with dread at the potential loss rather than jubilation over the potential gain of gladnesses and gratifications we fail to envision because we haven’t yet experienced them. …

Coming up: Vancouver’s Voxel Bridge

The Vancouver Biennale folks first sent me information about Voxel Bridge in 2018 but this new material is the most substantive description yet, even without an opening date. From a June 6, 2021 article by Kevin Griffin for the Vancouver Sun (Note: Links have been removed),

The underside of the Cambie Bridge is about to be transformed into the unique digital world of Voxel Bridge. Part of the Vancouver Biennale, Voxel Bridge will exist both as a physical analogue art work and an online digital one.

The public art installation is by Jessica Angel. When it’s fully operational, Voxel Bridge will have several non-fungible tokens called NFTs that exist in an interactive 3-D world that uses blockchain technology. The intention is to create a fully immersive installation. Voxel Bridge is being described as the largest digital public art installation of its kind.

“To my knowledge, nothing has been done at this scale outdoors that’s fully interactive,” said Sammi Wei, the Vancouver Biennale‘s operations director. “Once the digital world is built in your phone, you’ll be able to walk around objects. When you touch one, it kind of vibrates.”

Just as a pixel refers to a point in a two-dimensional world, voxel refers to a similar unit in a 3-D world.

Voxel Bridge will be about itself: it will tell the story of what it means to use new decentralized technology called blockchain to create Voxel Bridge.

There are a few more Voxel Bridge details in a June 7, 2021 article by Vincent Plana for the Daily Hive,

Voxel Bridge draws parallels between blockchain technology and the structural integrity of the underpass itself. The installation will be created by using adhesive vinyl and augmented reality technology.

Gfiffin’s description in his June 6, 2021 article gives you a sense of what it will be like to become immersed in Voxel Bridge,

Starting Monday [June 14, 2021], a crew will begin installing a vinyl overlay directly on the architecture on the underside of the bridge deck, around the columns, and underfoot on the sidewalk from West 2nd to the parking-lot road. Enclosing a space of about 18,000 square feet, the vinyl layer will be visible without any digital enhancement. It will look like an off-kilter circuit board.

“It’ll be like you’re standing in the middle of a circuit board,” [emphasis mine] she said. “At the same time, the visual perception will be slightly off. It’s like an optical illusion. You feel the ground is not quite where it’s supposed to be.”

Griffin’s June 6, 2021 article offers good detail and a glossary.

So, Vancouver is offering more than one opportunity to learn about and/or experience blockchain.

Blue Brain Project builds a digital piece of brain

Here’s more *about this virtual brain slice* from an Oct. 8, 2015 Cell (magazine) news release on EurekAlert,

If you want to learn how something works, one strategy is to take it apart and put it back together again [also known as reverse engineering]. For 10 years, a global initiative called the Blue Brain Project–hosted at the Ecole Polytechnique Federale de Lausanne (EPFL)–has been attempting to do this digitally with a section of juvenile rat brain. The project presents a first draft of this reconstruction, which contains over 31,000 neurons, 55 layers of cells, and 207 different neuron subtypes, on October 8 [2015] in Cell.

Heroic efforts are currently being made to define all the different types of neurons in the brain, to measure their electrical firing properties, and to map out the circuits that connect them to one another. These painstaking efforts are giving us a glimpse into the building blocks and logic of brain wiring. However, getting a full, high-resolution picture of all the features and activity of the neurons within a brain region and the circuit-level behaviors of these neurons is a major challenge.

Henry Markram and colleagues have taken an engineering approach to this question by digitally reconstructing a slice of the neocortex, an area of the brain that has benefitted from extensive characterization. Using this wealth of data, they built a virtual brain slice representing the different neuron types present in this region and the key features controlling their firing and, most notably, modeling their connectivity, including nearly 40 million synapses and 2,000 connections between each brain cell type.

“The reconstruction required an enormous number of experiments,” says Markram, of the EPFL. “It paves the way for predicting the location, numbers, and even the amount of ion currents flowing through all 40 million synapses.”

Once the reconstruction was complete, the investigators used powerful supercomputers to simulate the behavior of neurons under different conditions. Remarkably, the researchers found that, by slightly adjusting just one parameter, the level of calcium ions, they could produce broader patterns of circuit-level activity that could not be predicted based on features of the individual neurons. For instance, slow synchronous waves of neuronal activity, which have been observed in the brain during sleep, were triggered in their simulations, suggesting that neural circuits may be able to switch into different “states” that could underlie important behaviors.

“An analogy would be a computer processor that can reconfigure to focus on certain tasks,” Markram says. “The experiments suggest the existence of a spectrum of states, so this raises new types of questions, such as ‘what if you’re stuck in the wrong state?'” For instance, Markram suggests that the findings may open up new avenues for explaining how initiating the fight-or-flight response through the adrenocorticotropic hormone yields tunnel vision and aggression.

The Blue Brain Project researchers plan to continue exploring the state-dependent computational theory while improving the model they’ve built. All of the results to date are now freely available to the scientific community at https://bbp.epfl.ch/nmc-portal.

An Oct. 8, 2015 Hebrew University of Jerusalem press release on the Canadian Friends of the Hebrew University of Jerusalem website provides more detail,

Published by the renowned journal Cell, the paper is the result of a massive effort by 82 scientists and engineers at EPFL and at institutions in Israel, Spain, Hungary, USA, China, Sweden, and the UK. It represents the culmination of 20 years of biological experimentation that generated the core dataset, and 10 years of computational science work that developed the algorithms and built the software ecosystem required to digitally reconstruct and simulate the tissue.

The Hebrew University of Jerusalem’s Prof. Idan Segev, a senior author of the research paper, said: “With the Blue Brain Project, we are creating a digital reconstruction of the brain and using supercomputer simulations of its electrical behavior to reveal a variety of brain states. This allows us to examine brain phenomena within a purely digital environment and conduct experiments previously only possible using biological tissue. The insights we gather from these experiments will help us to understand normal and abnormal brain states, and in the future may have the potential to help us develop new avenues for treating brain disorders.”

Segev, a member of the Hebrew University’s Edmond and Lily Safra Center for Brain Sciences and director of the university’s Department of Neurobiology, sees the paper as building on the pioneering work of the Spanish anatomist Ramon y Cajal from more than 100 years ago: “Ramon y Cajal began drawing every type of neuron in the brain by hand. He even drew in arrows to describe how he thought the information was flowing from one neuron to the next. Today, we are doing what Cajal would be doing with the tools of the day: building a digital representation of the neurons and synapses, and simulating the flow of information between neurons on supercomputers. Furthermore, the digitization of the tissue is open to the community and allows the data and the models to be preserved and reused for future generations.”

While a long way from digitizing the whole brain, the study demonstrates that it is feasible to digitally reconstruct and simulate brain tissue, and most importantly, to reveal novel insights into the brain’s functioning. Simulating the emergent electrical behavior of this virtual tissue on supercomputers reproduced a range of previous observations made in experiments on the brain, validating its biological accuracy and providing new insights into the functioning of the neocortex. This is a first step and a significant contribution to Europe’s Human Brain Project, which Henry Markram founded, and where EPFL is the coordinating partner.
