The problem Supply management solves

In today's economy, the increasing demand for digitization is due to government initiatives.Surprisingly, transportation is currently highly dependent on paperwork that has not been securely digitized. Shipping information usually travels through numerous companies and contractors, which is something that should be avoided during this ongoing COVID-19 pandemic.

Keeping in mind, a late approval or a lost form can leave goods stuck and lead to further delay for the transportation of necessary goods to the COVID-19 hotspots.

Thus, inefficient product procurement processes can account for more damage.

A supply chain blockchain could boost transparency, trust and predictability allowing regional offices to track where a shipment from the central government is at any given time.

Dispute resolution rules could be agreed upon beforehand and applied instantly on the blockchain when necessary.

Blockchain can help regional governments realize the digital supply chain by providing a “single version of the truth” for the entire supply chain.

By sharing important information such as sales data, COVID risk levels, order and shipment information, companies can eliminate information delays and the uncertainty that contributes to “the bullwhip effect” and inflates the safety stock price.

With all regional and central government offices posting to a common ledger, citizens can gain visibility to their entire networks, from their regional offices to their central offices.

This enables them to foresee problems and address them, resulting in a smoother, more efficient supply chain.

The Block Covid app allows:

1. Affordable high-quality quotes from the source
2. On-demand purchasing, tracking and reordering.
3. Secure transactions and communications through smart contracts.
4. Direct connection to the regional manufacturing facility
5. Incentives for pricing quotes quickly.

Challenges I ran into

Managing Decentralization
Enabling blockchain technology to support decentralized applications managed by separate regions, and centralized, industry focused exchanges at the same time, required us to think and come up with an efficient model which turned out to be slightly complex.

Data Complexity
A blockchain application stores every transaction in a distributed ledger, which can add up, particularly when it is used by multiple parties.These factors can lead to larger data structures that each regional government might have to manage. The supply chain's side of the network must include context for transactions, such as a purchase order, the owner of the materials, the timestamp and the equipment, to effectively operate at scale. To overcome this problem, we created a common wallet network for transaction management which largely reduced the data complexions.

Need For Smart Contracts
Blockchain applications are written as smart contracts that could help streamline supply chain management processes that cross organizational boundaries. We wrote our own smart contracts in order to fit certain corner case transactions.
