NTT Digital, a subsidiary of NTT Docomo, has announced that it has begun operating a validator node on the Solana blockchain as of December 3. The development reflects the company’s growing involvement in Web3 infrastructure and highlights its intent to play a bigger role in the global decentralized ecosystem. Executives indicated that the move takes advantage of NTT’s technical foundation, built over several decades in Japan’s telecommunications sector, to enhance network stability, security, and decentralization within the Solana ecosystem.
A validator in a blockchain network is responsible for verifying transactions and contributing to the consensus process that maintains network integrity. Solana, known for its low transaction costs and high throughput, hosts a broad array of decentralized applications. Industry analysts suggested that participation from a major enterprise such as NTT Digital is expected to further reinforce Solana’s operational reliability.
Building on Multi-Chain Validator Expertise
NTT Digital already has experience managing validator nodes across several blockchain environments. Its validator operations extend to networks such as NERO Chain, ZetaChain, and Injective, forming part of a multi-chain strategy designed to strengthen Web3 infrastructure both within Japan and internationally. Company representatives stated that the organization intends to support long-term decentralized network growth by offering scalable infrastructure and dependable node operations.
The broader NTT Group has also increased its engagement with blockchain technologies. NTT Data, another arm of the conglomerate, operates a validator for the NEAR Protocol. Observers view this as evidence of a coordinated corporate shift toward deeper participation in Web3 technologies across multiple business units.
Beyond validator functions, NTT Digital provides an infrastructure product known as N node. This API-based platform is designed to simplify developer access to blockchain data, making it easier to build Web3 applications with reliable and scalable backend support. The company sees this offering as a way to reduce technical barriers and encourage broader adoption of decentralized systems.

Technical Capacity Strengthens Solana’s Performance
Solana promotes itself as a highly performant and censorship-resistant blockchain, and maintaining its speed requires enterprise-grade hardware. The network depends on validators equipped with high-core-count CPUs, substantial memory resources, and low-latency connections to major clusters of validators. Drawing from its telecommunications background, NTT Digital is positioned to deliver the type of robust, low-latency infrastructure required to support Solana’s demanding technical needs.
Validators on Solana earn rewards through a blend of protocol inflation and delegated staking. NTT Digital’s participation, therefore, increases the pool of trusted staking options for SOL holders who prefer delegating to well-established entities. As Solana’s mainnet attracts more validators, competition for delegated stake continues to grow. The company aims to strengthen its role by pairing enterprise-level reliability with technical excellence.
Industry observers say that the involvement of prominent corporations like NTT Digital enhances confidence in Solana’s network performance and overall resilience. A more decentralized and stable validator set may also encourage additional institutional and developer engagement, potentially drawing more builders and investors to the ecosystem.
With plans to expand its Web3 infrastructure initiatives, NTT Digital aims to position itself as a central contributor to the decentralized internet’s evolution.
