UNESCO (United Nations Educational, Scientific and Cultural Organization) has endorsed OER for several reasons, aligned with its mission to promote peace and sustainable development through education, science, culture, and communication. 

Six specific sustainable development goals have been identified to support OERs and BCT (UNESCO, 2022).

Blockchain as a Service (BaaS) democratizes access to blockchain technology, enabling businesses and developers to leverage its benefits without the complexities of managing the underlying infrastructure. By providing a cost-effective, scalable, and user-friendly platform, BaaS fosters innovation and accelerates the adoption of blockchain across various industries.

Blockchain of Things (BCoT) represents a powerful synergy between blockchain and IoT technologies, addressing key challenges in security, transparency, and efficiency within IoT networks. By leveraging the strengths of both, BoT enables more robust, scalable, and reliable IoT ecosystems, paving the way for innovative applications across various industries.

Estonia's implementation of blockchain technology across various government services sets a benchmark for digital governance. By enhancing security, transparency, efficiency, and accessibility, Estonia has demonstrated how blockchain can revolutionize public administration, fostering a more resilient and trustworthy government. This pioneering approach has positioned Estonia as a leader in digital innovation, offering valuable insights for other nations looking to modernize their government services.

France's government has adopted a supportive and proactive stance towards blockchain technology. By establishing clear regulations, providing funding and support for innovation, and exploring public sector applications, France aims to become a leader in the blockchain space. The government's efforts to balance regulation with fostering innovation are central to its strategy, promoting the growth and integration of blockchain technology across various sectors.

The Energy Web Foundation focuses on accelerating the energy transition through blockchain technology. In relation to educational blockchain, their initiatives could offer insights into blockchain applications for energy management education, real-world case studies for students, and resources for understanding decentralized energy systems. They provide practical examples of blockchain enhancing transparency, security, and efficiency in energy sectors, which can be valuable educational content for students learning about sustainable technologies and blockchain’s role in industry transformation.

Plastic Bank is an organization focused on reducing ocean plastic while improving lives. It empowers communities to collect and exchange plastic waste for money, items, or blockchain-secured digital tokens, creating a circular economy. This initiative supports environmental conservation and provides economic opportunities for people in impoverished regions. The Plastic Bank platform ensures transparency and traceability in the plastic collection and recycling process.

Blockchain technology (BCT) helps supply chains ethically by enhancing transparency and accountability. Platforms like Bext360 use blockchain to track products from origin to consumer, ensuring that all transactions are visible and immutable. This promotes fair wages and working conditions for producers, as every step is documented and verifiable. Additionally, blockchain helps prevent fraud and ensures that products are sustainably sourced, fostering trust and ethical practices throughout the supply chain.

Bext360 leverages blockchain, AI, and IoT to enhance supply chain transparency and efficiency, particularly in the agriculture and forestry sectors. Their platform tracks products from origin to consumer, ensuring fair wages for farmers and promoting sustainable practices. By providing real-time data and secure transactions, Bext360 aims to create more ethical and efficient supply chains.

Steemit is a blockchain-based social media platform where users can create, share, and monetize content. It uses the Steem blockchain to reward contributors with cryptocurrency (STEEM) based on community voting and engagement. This system incentivizes quality content and active participation, offering a decentralized alternative to traditional social media platforms.

CryptoPunks are a set of 10,000 unique digital collectible characters stored on the Ethereum blockchain. Each item in the collection is a 24x24 pixel, 8-bit-style portrait with a unique set of attributes.
