区块链从技术结构上来说可被看作一个分布式“账本”,通过其网络中不同节点间的共识来记录数据,具有难以被篡改的特点。气象数据是一种不可复验的时间性数据,利用区块链对于气象数据进行记录,可被看作一种无法证伪的历史书写。近年来国内有多起关于气象数据的争议事件。如2012年美国驻京大使馆开始发布自测的空气质量数据,曾由于其发布的数据与官方相悖而引起广泛关注与讨论。2022夏天的持续高温中,手机天气app中显示的极端高温多次被官方辟谣。此外由于高温津贴引起的劳务纠纷每年也常有发生。装置“天气块报”使用几台硬件条件一致的设备作为节点构建私有链,每个节点负责读取不同的气象数据源,节点间利用PoW共识机制生成区块,并争取记录在区块链数据库中的权力,并播报其记录结果。此作品尝试检视与讨论区块链去中心化结构所带来的公平与信任,与其和来自真实世界的或带有偏见的数据相连接时所引发的矛盾,及其可能带来的对数据强权的推波助澜等不可预期的后果。

In terms of its technical structure, the blockchain can be observed as a distributed “ledger” in which data is recorded by consensus at different nodes on a network and is fundamentally tamper-proof. Climatic data is a form of temporal data that cannot be re-validated once obtained. As a result, applying the blockchain to record climatic data can be seen as a means to truthfully write history. Various incidents regarding climatic data disputes have occurred in China over the past few years. For instance, the air pollution index self-measured and published by the United States Embassy in Beijing instigated a public discussion and widespread concern in 2021, as it contradicted the official Chinese data; during the long heatwave in the summer of 2022, extreme temperatures reported on mobile apps were refuted by the local government multiple times; meanwhile, labor disputes while working under high temperatures occur frequently each year. The installation entitled The Weather Consensus builds a private blockchain using devices with identical hardware conditions, such as nodes, each responsible for obtaining information from different climatic data sources. Blocks are generated between nodes under the PoW consensus mechanism as they seize the power that is recorded in the blockchain database, the results of which are then broadcast. This artwork attempts to examine and discuss justice and trust enabled by the decentralized structure of the blockchain, as well as the paradox engendered by the connection between the blockchain and data from the real world or skewed by bias, and the unpredictable consequences it might induce such as the reinforcement of data hegemony, among many others.
