Neo

Neo receives a B- risk grade (31/100) from Hindenrank, where lower scores indicate lower risk. Moderate risk — mature dBFT consensus with instant finality and long track record, but centralized node set, Chinese regulatory exposure, and declining ecosystem vitality create meaningful uncertainty. Neo is a Layer 1 blockchain platform founded in 2014, often called the 'Ethereum of China,' using a delegated Byzantine Fault Tolerance (dBFT) consensus mechanism for instant transaction finality. With a dual-token model (NEO for governance, GAS for fees), approximately $50 million in ecosystem TVL, and a $273 million fully diluted valuation, Neo is a mature but declining L1 chain. Its B- grade reflects the proven dBFT consensus design with 8+ years of operation and no major exploits on the core chain, but material risk from a small centralized consensus node set, Chinese regulatory exposure, declining ecosystem vitality, and a June 2025 remote token theft vulnerability disclosed by Tencent.

The key risks identified for Neo are: (1) Neo uses delegated Byzantine Fault Tolerance (dBFT) with a small set of elected consensus nodes. A smaller validator set means fewer nodes need to be compromised to halt or censor the network. Unlike proof-of-stake chains where anyone can become a validator, dBFT consensus participation is restricted to elected nodes. (2) Neo was founded in China and has historically had strong ties to Chinese developer and user communities. Chinese regulatory actions against cryptocurrency have directly impacted Neo's ecosystem in the past, and ongoing regulatory uncertainty in China creates jurisdictional risk for the project. (3) In June 2025, Tencent security researchers disclosed a vulnerability that allowed potential remote theft of native tokens from Neo blockchain users. While the vulnerability was patched, it demonstrates that the Neo codebase can have exploitable security issues. (4) Neo's ecosystem activity, TVL, and developer engagement have declined significantly from 2018-2021 peaks. Competing L1 blockchains offer deeper DeFi ecosystems, more active developer communities, and higher transaction throughput, making it increasingly difficult for Neo to attract new users and capital.

Neo scores 31/100 across eight risk dimensions: Mechanism Novelty: 0/15, Interaction Severity: 5/20, Oracle Surface: 0/10, Documentation Gaps: 3/10, Track Record: 6/15, Scale Exposure: 5/10, Regulatory Risk: 6/10, Vitality Risk: 6/10. The highest risk area is Regulatory Risk at 6/10.

Among 56 rated L1 protocols on Hindenrank, Neo ranks #22 by safety (lowest risk score = safest). Its 31/100 risk score and B- grade place it in the middle tier of L1 protocols.

Neo scores 6/15 on the Track Record risk dimension, indicating some history of security incidents or exploits. Higher scores reflect more severe or frequent incidents. Review the full risk report for details.
