Unlock the Power of Web3 for the AEC Industry

Put BIM Files to the Blockchain, Define Contractor Payments, Increase Security

Arcartera Protocol focuses on blockchain infrastructure for the AEC Industry. We use smart contracts to bring the building environment to Web3. Smart Contracts play a major role in our eco-system. A typical mega city like Hong Kong has a construction market of 35 Billion USD annually. Delays and Overbudgeting usually cause 10-50% additional costs. These can be caused by Mis-Communication, Distrust and lack of transparency. PropTech, in particular Arcartera’s Decentralized App (Dapp) and DeFi Protocols can help to improve this, saving billions of dollars.D

Arcartera is bringing the benefits of Blockchain to the Architecture, Engineering, and Construction (AEC) industry. The AEC industry is known for its complex and multifaceted projects, and Blockchain technology offers a solution to improve efficiency and transparency in these projects.

One major benefit of Blockchain in the AEC industry is the ability to securely share and access project information in real-time. With Blockchain, all stakeholders – including architects, engineers, contractors, and clients – can access and update project data in a secure and tamper-proof manner. This improves collaboration and reduces delays caused by a lack of access to critical information.

Another benefit of Blockchain in the AEC industry is the ability to track and verify the authenticity of materials and components used in a project. By using smart contracts and RFID tags, Blockchain technology can create an immutable record of materials and components used in a project, ensuring that they meet the necessary standards and regulations.

In addition, Blockchain technology can also improve the efficiency of the bidding and procurement process for AEC projects. By using Blockchain-based platforms, contractors can submit bids and proposals in a secure and transparent manner, reducing the risk of fraud and corruption.

Overall, Blockchain technology has the potential to revolutionize the AEC industry by improving collaboration, transparency, and efficiency in projects. We hope this video has provided you with a better understanding of the benefits of Blockchain in the AEC industry and how it can be applied to improve the building process.

Arcartera Limited is a pioneer in building Blockchain Applications. Before specialising on Architectural Blockchain, the team had built guidelines for Web3 Payment Systems and received a letter of Appreciation from the Monetary Authority of the Hong Kong government. HKMA is the defacto Central Bank of Hong Kong, making Arcartera the first blockchain start-up to receive such endorsement.

This payment system is now also part of the company’s Contractor Payment System. It utilizes Tokens on Shards while running on an ecological friendly Carbon footprint.

ARCA is a digital token, created for the exchange and transfer of data and value on  Arcartera’s payment network. It is also used for staking and to govern community funding,

Its supply is disbursed over time to drive near-term growth and long-term sustainability. ARCA value is designed to increase with a rise in usage volume, the number of coins is fixed.
