Mozambique: How digital identities can help in case of a natural catastrophe

Last Thursday, cyclone Idai left a devastating trail in Mozambique. With more than 400 deaths accounted for, the International Red Cross estimates more than 400.000 people were left homeless. The United Nations is describing it as “the worst climate disaster ever in the southern hemisphere”.

The Red Cross teams on sight are distributing shelter supplies to affected families and chlorine tablets to purify the water. Diseases transmitted by contaminated water are one of the biggest concerns in case of a catastrophe where normal water supplies are interrupted.

“Many families have lost everything” according to the Red Cross spokesperson, Jamie LeSueur. If they also lost their documents or if the governmental identification processes have been compromised, not being able to prove who they are can cause irreparable damage to their short term survival.

Mozambique has the third highest smartphone adoption rate in the African continent (sources 1, 2 and 3) meaning that digital identities could play a pivotal role in easing people’s suffering in a natural catastrophe scenario. This is how:

1) Aid expedition

Humanitarian aid distribution – whether shelter, food or cash based assistance – requires a strong identification layer. How else could an NGO account for what aid has been distributed and to whom?

Current identity management systems are paper-based and make this process reliant on vouchers. Paper vouchers. This not only slows the aid distribution process – and in a scenario like this time is lives – but it also jeopardizes the quality of aid provided. If a citizen is to lose their voucher they would have to start the aid request process all over again. Worse: unfortunately it is quite common, in a scenario like this, that vouchers are stolen or subject to fraud. In a paper-based system, NGOs have no means to efficiently combat wrongful behaviours.

Digital identities will provide an efficient way for an affected person to request aid. A trusted organisation can quickly issue a digital credential that verifies that person’s identity and allows them faster access to their services. All vouchers are digitised and, alongside the identity credentials, are held in a digital identity wallet in that person’s mobile device. Digital vouchers can’t be lost or stolen and provide an NGO with important and reliable information about who has been aided.

Digital identities leveraging distributed ledger technology provide a private and secure channel to share and request personal data to and from an organisation.

2) Displacement to another city/country

In catastrophe scenarios like this, the people affected are often displaced to another city or country. They become refugees. Not being able to prove who they are prevents them from accessing services like healthcare, education or banking and excludes them from society.

Digital identities allow for a trusted organisation such as the government or an NGO to issue a digital credential attesting to that person’s identity. Through the use of distributed ledger technology that credential is verified with a signature from that organisation. A signature that cannot be deleted or subject to fraud.

When verifying a persons’ affected identity, the verifier does not need to verify the accuracy of the data contained in the credential. The verifying party will validate the issuers’ signature who issued and attested to this credential to then decide whether he trusts the issuers’ assessment about the accuracy of the data.

A process like this, that eliminates the possibility of identity fraud and where everyone in the network has the same source of truth about which credentials are still valid and who attested to the validity of the data inside the credential (without revealing the actual data) will speed and facilitate identification processes between governmental departments and between governments. Accounting for less bureaucracy, less need for data management and possible frauds.

Above all, this will ease people’s suffering as it will allow them to quickly access services, such as healthcare or banking, and be included in society again. Their identities and their access to human rights are protected. Right there on their mobile devices.

Digital Identity: Why use blockchain?

A distributed ledger (commonly called “blockchain”) enables everyone in the network to have the same source of truth about which credentials are valid and who attested to the validity of the data inside the credential, without revealing the actual data.

Tykn’s digital identity platform uses Sovrin. A global registry for public keys to verify offchain data with those keys.

Through the infrastructure of Sovrin, the verifying parties do not need to check the validity of the actual data in the provided proof but can rather use the Sovrin blockchain to check the validity of the attestation and attesting party (such as the government) from which they can determine whether to validate the proof.

For example, when an identity owner presents a proof of their date-of-birth, rather than actually checking the truth of the date of birth itself, the verifying party will validate the government’s signature who issued and attested to this credential to then decide whether he trusts the government’s assessment about the accuracy of the data.

Hence, the validation of a proof is based on the verifier’s judgement of the reliability of the attestor.

Leveraging the Sovrin blockchain establishes trust between the parties and guarantees the authenticity of the data and attestations, without actually storing any personal data on the blockchain.

This is crucial as a distributed ledger is immutable, meaning anything that is put on the ledger can never be altered nor deleted, and thus no personal data should ever be put on the ledger.

Sovrin is a global platform, with 60+ trusted Stewards (like IBM, CISCO and Tykn) operating the network, covering every continent (except antarctica).

The Future of Cash Based Assistance


The International Disaster Database records a steady increase in the frequency of natural disasters over the past 35 years. In the past 10 years, the number of people affected by humanitarian crises have almost doubled, whilst the cost of humanitarian assistance has tripled. For this reason, the humanitarian world is undergoing a transformation in the way that aid is delivered. This transformation must not compromise the humanitarian principles of impartiality, neutrality and independence.

Assistance must always reach the most vulnerable. An effective way to support people affected by natural disasters is through a combination of CBA and FBF. FBF allows for both decision-makers and people affected to better prepare for and cope with natural disasters and thus reducing needs when disaster strikes. CBA offers a more efficient and dignified means to deliver assistance, empowers people in need and fosters local economies.


However, these CBA programs face multiple challenges. Every disaster type and local context has its unique set of challenges and in turn a unique set of solutions. The scope of the current solutions differ dramatically from high digital connectivity, to that of low or no connectivity. For this reason we started with a common set of parameters that we want to improve on. These can be clustered as:

TIME: Depending on the location, getting cash-based assistance to the most vulnerable can be a slow process. We aim for a system to trigger fund release from anything up to 6 days to 24 hours before a natural disaster strikes (for early warning and early action).

SAFETY: Both Red Cross field staff & volunteers, and the recipients of assistance, are vulnerable due to large amounts of physical cash.

COSTS: International bank transfers, hiring security and in-country logistical challenges creates high costs.

INCLUSIVENESS: Beneficiaries do not always have a proof of identity and are therefore not easily included in humanitarian aid across various humanitarian organizations.

SCALABILITY: Current solutions differ dramatically in each context.


510 together with Tykn.tech are exploring the potential of humanitarian aid integrating blockchain in current humanitarian operations.


We gathered both teams to meet with a diverse group, including experienced Red Cross cash delegates, system engineers, econometricians and social scientists. Through numerous sessions, we established the current and potential user journeys for all stakeholders. Highlighting challenges of beneficiary registration due to a lack of proof of identity. Incorporating the knowledge of a 150 years of providing humanitarian aid, we look at the social & economic factors that affect the potential technological applications and algorithms that can help identify and ultimately reach the most vulnerable.


The project will conduct a pilot integration in at least one of the current Red Cross operations during 2018.


The ultimate goal is to develop a system that can adapt to any type of disaster in any location. In the interest of scalability, we are exploring two very different local contexts. One with high digital connectivity as with St Maarten, and one with low to no connectivity such as the most vulnerable areas of Malawi.

510 x Tykn Press Release

510 is exploring the use of Blockchain in Humanitarian Aid with Tykn.tech.

The organization is looking for smarter and more efficient solutions to enhance aid when a natural disaster strikes.

510 and Tykn.tech are researching the potential of blockchain to improve cash based assistance. The organization aims to develop a system with a digital wallet that can be used to transfer money faster to those affected in a disaster area. With this money, those affected can purchase necessities like food, water and other relief goods. Today, the 510 data team of the Netherlands Red Cross and Tykn.tech are announcing their cooperation at The North American Bitcoin Conference in Miami.

In some specific cases, the Red Cross chooses to give money to those affected by a disaster to buy the things they need, like food. This process fosters the local economy, increases the resilience of the affected communities and reduces the need of food parcel distributions.

Safe and Efficient

510 and Tykn.tech are researching how blockchain technology can make cash distributions both safer and more efficient. The use of blockchain can, among other things, reduce the logistical challenges where cash distributions are involved. This makes the situation safer for both Red Cross field staff and those affected by the disaster. In parallel, the use of blockchain has the potential to lower overhead costs and accelerate the aid process. As each digital wallet could be linked to an individual, it would be easier to see who has or has not received aid.

“We know from experience that in some specific cases, giving money instead of relief goods works better. Blockchain could optimize this process. To insure we explore to the fullest, we have chosen to work with Tykn.tech”, says Stefania Giodini, team leader of the 510 data team.

“Because of my experience as a refugee, I know the importance of the responsible use of data in humanitarian aid. Working with 510 ensures we can create a process that meets the needs of those affected.”, says Tey el-Rjula, founder of Tykn.tech.

How and if humanitarian aid can integrate blockchain and what the practical implications will be is currently being researched.


St. Maarten

St-Maarten has been heavily affected by hurricane Irma and therefore there are currently many Red Cross projects, both running and planned, that focus on recovery. 510 is building on the learnings of St-Maarten’s unique set of challenges and is investigating the potential of blockchain to positively impact these projects. The ultimate goal is to develop a system that can adapt to any type of disaster in any local context.
