Solana's Accelerate convention, one of the largest community events for the blockchain ecosystem in China, was abruptly postponed on October 16, with attendees who had traveled to Shanghai speculating about the circumstances behind the decision. The postponement underscores the regulatory sensitivities surrounding large-scale blockchain gatherings in mainland China.

The gathering had been scheduled to take place at the Shangri-La Hotel in Shanghai on October 16. According to reports circulating on social media, attendees who arrived at the designated venue were left waiting for more than an hour without being granted access.

Lily Liu, president of the Solana Foundation, attributed the postponement to the publicity surrounding the convention. "Event registrations quadrupled overnight, far exceeding the event cap we had registered with local authorities, and we had no way to prevent people from overwhelming the venue," she said.

Liu stated that the foundation postponed the event until it can "better accommodate the breadth and scale of our community," and apologized to the attendees who had traveled to be part of the experience.

However, photographs suggesting the presence of law enforcement officers, along with first-hand accounts of officials blocking access to the venue, point to local authorities intervening over the event's cryptocurrency links, even though no session on the Accelerate Shanghai program addressed the topic.

Changpeng Zhao, founder of Binance, weighed in on the postponement: "Sad to see. Looks like they really didn't know the local policies?" His remarks hinted that the enforcement of China's anti-crypto policies was the real reason the convention was called off.

Zhao also pointed out that this was not the first time the convention had drawn the attention of local police. The 2025 Solana Accelerate Shenzhen event was temporarily canceled citing public safety reasons after a similar overcrowding situation unfolded.

Other Chinese crypto sources indicated that the heavy publicity surrounding the event, combined with the promotion of an office established by the foundation, gave it a high profile. According to these accounts, authorities stepped in to shut down the gathering and enforce local crypto policies that have been in place since 2021 and were recently reinforced by the People's Bank of China (PBOC). Under that framework, regulators declared cryptocurrency-related business activities to be illegal financial activities, and both crypto trading and mining were banned nationwide. The Solana Foundation has not announced a new date for the postponed Shanghai gathering.
