Aptos’ validator set has shrunk sharply in both size and geographic spread, according to a report cited by PANews. The network had 146 validator nodes across 22 countries and 48 cities in October 2024. By September 2026, that had dropped to 84 nodes in 13 countries and 28 cities, with most of the remaining infrastructure concentrated in Europe and the Americas. Outside those regions, only Tokyo still had a node. The report ties the shift to two pressures that hit at the same time. On the technical side, the Baby Raptr upgrade in June 2025 and AIP-131, also known as Velociraptr, pushed Aptos block times below 50 milliseconds. That improved user-facing performance, but it also made latency and data center location more important for validators because proposal success rates affect rewards. On the economic side, annual staking rewards fell from 7% to 2.6%, while APT dropped from $9.50 to $0.58 over the same period. Even though average stake per validator rose from 5.75 million APT to 8.97 million APT, the report said annual rewards measured in U.S. dollars still fell 96%. The piece argues that Aptos reflects a broader proof-of-stake problem: faster consensus and lower token issuance can support network efficiency, but they can also raise operating pressure and reduce geographic diversity among validators.

Aptos’ validator set has shrunk sharply, with the network moving from 146 validators across 22 countries and 48 cities in October 2024 to 84 validators across 13 countries and 28 cities by September 2026. The article argues this was not just a drop in node count. It ties the shift to faster chain performance, reward design changes, and a steep decline in APT’s dollar price, all of which altered where validators could operate economically. After the Baby Raptr upgrade and AIP-131, also known as Velociraptr, pushed Aptos block times below 50 milliseconds in June 2025, latency and data center location carried more weight for validator proposal success. Because Aptos rewards are linked to staked amount, reward rate, and proposal success rate, operators farther from the main validator cluster faced weaker revenue performance. At the same time, annual staking rewards fell from 7% to 2.6%, while APT dropped from $9.50 to $0.58. Even though average stake per validator rose from 5.75 million APT to 8.97 million APT after weaker operators exited, the annualized reward measured in U.S. dollars still fell 96%. The piece says this tension is not unique to Aptos. It also points to Ethereum’s EIP-8363 debate and argues that long-term decentralization depends on whether validators can survive weak markets, keep operating costs down, and leave room for new entrants.

ChainFeeds’ Sept. 18 research roundup pulled together five separate market and policy narratives that are shaping crypto discussion this week. One report argued that Aptos has seen a sharp contraction in validator count and geographic distribution, with lower staking rewards, a steep drop in APT’s price, and higher operating requirements squeezing smaller operators. Another focused on Ethena, saying a governance-approved fee switch would begin directing protocol revenue toward ENA buybacks once USDe’s 14-day average supply rises above $7.5 billion, with stock perpetuals, improving funding rates, TRON deployment, CEX collateral integrations, and Ethena Pay cited as possible growth drivers. The roundup also highlighted Arc’s mainnet debut as a fresh battleground for Meme traders. According to block explorer data cited by PANews, daily transactions topped 1.16 million on Sept. 16, while address growth and USDC inflows accelerated as traders rushed to secure early positions. A separate piece examined ZEC’s rally, noting that its market capitalization had climbed to about $23.2 billion by Sept. 17, pushing it into the global top 10 as U.S.-listed exchange-traded products, options trading, and a revived “private Bitcoin” narrative drew attention. The final report turned to Washington, where the U.S. Senate failed to advance the CLARITY Act on Sept. 15, leaving the SEC and CFTC in a more prominent position as they move ahead with interim crypto rulemaking and interpretive guidance.
