La (ou les) blockchain (s), une réponse technologique à la crise de confiance

Abstract

Dans sa forme canonique, la blockchain est un refus des tiers de confiance. Cette technologie repose sur une posture idéologique qui n’est pas exempte de populisme. Ce refus des institutions établies s’explique en partie par la crise de confiance que traversent les sociétés modernes. Le solutionnisme technologique qui voudrait établir la confiance par algorithmes, sans ancrage social ou juridique, est illusoire. Compte tenu des coûts et des risques, l’usage de la blockchain canonique (sans tiers de confiance) présente peu d’intérêt en dehors d’un nombre limité de domaines. En revanche, la mise en œuvre des technologies blockchain par des institutions dépositaires de confiance, à l’intérieur d’un cadre juridique et social, paraît promise à un bel avenir. Mais seule une veille active permettra à ses acteurs d’en bénéficier pleinement.

Blockchain-Based Supply Chain System for Olive Fields Using WSNs

“…For precision agriculture, the authors in Ref. [40] used sensors and Raspberry Pi to assess soil fertility and productivity. is approach is different to our approach since we used Ethereum.…”

“…Moisture Monitoring. In our work, we have developed a water-saving irrigation control system that is based on wireless sensor networks [40], whereby the system comprises low-power wireless sensor nodes that communicate through an adhoc ZigBee network. We will monitor soil moisture information parameters such as soil water degree, temperature, and relative humidity that can all be used to measure moisture potential.…”

Implications for Agricultural Producers of Using Blockchain for Food Transparency, Study of 4 Food Chains by Cumulative Approach

“…In general, modern societies are going through a crisis of trust [8], as people do not believe what the media says about the food industry [9]. Trust and reliability are perceived as an essential determining factor of a good relationship between buyers and sellers [10].…”

“…These processes would contribute to the transparency of products. However, the concept of blockchain at the beginning would be to replace the trust in official institutions, [8,11,12] and thus it proposes an alternative way to substitute them. Therefore, this technology would be conducive to solve the trust issues in the sharing economy.…”

“…In other words, it appears that the technology is being used for purposes other than the problems it is likely to solve [30]. Some authors argue that it would ultimately consist of technological solutionism [8] and others hypothesize "technology hype" [31]. For instance, investors would confuse bitcoin and blockchain, and sometimes they use bitcoin performance as an indicator of the expected success of blockchain technology [32] or blockchain-backed projects.…”
