The company is leveraging its advanced technical expertise, which is built over decades in Japan’s telecommunications industry, to support Solana’s network stability, security, and decentralization.
NTT Digital Strengthens Presence Across Major Blockchains
A validator is a node that verifies blockchain transactions and participates in the consensus process that secures the network.
Solana, known for its high throughput and low transaction fees, supports a large ecosystem of decentralized applications (dApps). The entry of a major Japanese enterprise like NTT Digital is expected to further bolster the network’s reliability.
NTT Digital has already established a track record operating validators on multiple blockchain networks. These include:
- NERO Chain
- ZetaChain
- Injective
This multi-chain strategy aligns with the company’s broader goal: strengthening Web3 infrastructure both in Japan and globally. Through reliable node operations and scalable infrastructure, NTT Digital aims to support the long-term growth of decentralized networks.
The wider NTT Group is also deepening its involvement in blockchain technologies. For example, NTT Data operates a validator for the NEAR Protocol, highlighting a group-wide push into Web3.
Beyond validator services, NTT Digital offers an infrastructure product called “N node”, an API-based platform that simplifies access to blockchain data. This enables developers to build Web3 applications with more ease and reliability.
Enterprise-Level Infrastructure Powering Solana
Solana positions itself as “the world’s most censorship-resistant, high-performance blockchain,” and validators are crucial to achieving that goal. Maintaining Solana’s speed and performance requires enterprise-grade hardware with:
- High-core-count CPUs
- Large memory capacity
- Low-latency connections to major validator clusters
Drawing on its telecommunications heritage, NTT Digital provides robust, low-latency infrastructure capable of meeting Solana’s demanding technical requirements.
Validators earn rewards through protocol inflation and delegated staking, meaning NTT Digital’s participation also expands reliable staking options for SOL holders. This benefits users looking for trusted entities to stake their assets with.
As Solana’s mainnet continues to attract more validators, competition for stake delegation is increasing. NTT Digital aims to strengthen its presence in the ecosystem by combining technical excellence with enterprise reliability.
Boosting Solana’s Global Ecosystem Growth
The participation of major corporations like NTT Digital is expected to enhance confidence in Solana’s network performance and resilience. A more stable and decentralized validator set also increases appeal for users and institutions considering investments or building on Solana.
As NTT Digital deepens its role across Web3 infrastructure, the company aims to become a core pillar in supporting the decentralized internet of the future.
