Digital advancement in government and the public sector

Through our participation in the Kyoto Big Data Utilization Platform and the "Chain Up KYOTO" working group it spun off, we introduce our work and knowledge on advancing digital government. We cover proof-of-concept themes for applying Web3 and blockchain to public policy, such as building community ties, digital certification, and regional payments.

Where Web3 applies to government DX

The value Web3 and blockchain technology can bring to local-government policy falls into four areas, where tamper-resistant records, trusted data sharing across organizations, and resident self-sovereignty come into play.

Building community ties

For hometown-tax-payment programs, relocation initiatives, and building "related population" (people with an ongoing connection to a region), NFTs and digital badges can make a person's history of engagement visible, helping support people who maintain ties to a region over time.

Digital certification and digital identity

Issuing residence certificates and other credentials as DID/VC (decentralized identity / verifiable credentials) can combine tamper resistance with resident self-sovereignty, while also making counter operations more efficient.

Regional currency and regional payments

Support for digitizing regional currency or premium gift certificates that circulate within a region, and for visibility into payment data among local businesses, built on a blockchain foundation.

Transparent government administration

Recording the use of donations, subsidies, and grants on a tamper-resistant ledger to strengthen accountability to residents. This can also apply to fund management at NPOs and public-interest organizations.

"Chain Up KYOTO" working group participation

Since March 10, 2026, we have participated in "Chain Up KYOTO," a working group formed out of the Kyoto Big Data Utilization Platform. Through study sessions and project discussions, we take part in debate on the social implementation of Web3 and blockchain.

• Participation in discussions on Web3 use cases for local-government DX
• Participation in discussions on the direction of regional tokens and NFT initiatives that build community ties
• Participation in discussions on the technical points around digital certification and digital-ID use
• Sharing knowledge on Web3 and blockchain implementation

Themes worth exploring in local government and the public sector

The following are themes that could be explored in local government and the public sector — these are not a record of projects Netsujo has delivered. The actual feasibility of any of them needs to be assessed against the specific regulation, budget, data-handling requirements, and operating structure involved.

Using community-tie and digital-certification tools (example theme)

NFT-based approaches are being explored for making related-population activity visible and for digital resident certificates — there are many points to work out in advance, from the issuance and grant flow to the resident-facing experience.

Digital certification and digital identity, DID/VC (example theme)

Interest is growing in using DID/VC to issue and manage various resident certificates and qualifications in a tamper-resistant form, with discussion moving toward reducing counter workload while letting residents self-serve.

A regionally circulating payment foundation (example theme)

Digitizing regional currency and premium gift certificates, and making payment data among local businesses visible, are now technically achievable ways to keep money circulating within a region.

Transparent government operations and record-keeping (area we can support)

Using a tamper-resistant ledger for how subsidies and grants are spent, and for the integrity of government documents. This strengthens accountability to residents and improves trust in data shared across departments.

Frequently asked questions

Is it worth local governments adopting Web3 or blockchain?

It fails if adoption itself becomes the goal. It works when there is a genuine need — strengthening accountability to residents, needing tamper-resistant records, or sharing trusted data across organizations — that is genuinely hard to solve without blockchain. Start from the problem and work backward to where it applies.

How does government DX relate to the Digital Garden City Nation vision?

That national policy vision sets out priority measures to accelerate digital implementation in regional areas. Web3 and blockchain touch several of its priority areas, including building community ties, digital identity, and regional currency, so adoption can proceed in a way that aligns with that framework.

Where should we start?

We recommend starting by clarifying the problem in the target business area, then following the sequence: make the problem visible → confirm whether blockchain applies → verify with a small PoC → make the production decision.

How long does a PoC take and what does it cost?

It depends on scope, but a minimal PoC typically takes 2–3 months and can start from a budget in the low millions of yen. We provide a concrete scope and team proposal after an initial hearing.

How is residents' personal information handled?

We do not recommend recording personal information itself on a blockchain. A common approach is to record only a "hash of the proof" on-chain where verifiability is needed, while managing the underlying data securely elsewhere. Combining this with zero-knowledge proofs (ZK) can achieve both privacy and verifiability.
