Grass roots power concerns all aspects of people's daily production and life. In order to safeguard the vital interests of the people, the discipline inspection and supervision institutions have constantly promoted the implementation of supervision, found and remedied corruption and style problems around the people with accurate and effective supervision, and let the people feel that the right wind, discipline and anti-corruption are around. At the same time, it must be noted that in practice, grass-roots supervision still faces such problems as insufficient supervision power, asymmetric information, low enthusiasm of the masses to participate in supervision actively, and limited channels. It is important to solve the problem of grass-roots supervision and strengthen the information construction. Based on the primary responsibility of supervision, local discipline inspection and supervision institutions actively promote the deep integration of information technology and discipline inspection and supervision, promote the implementation of supervision, and safeguard the vital interests of the masses. It has become the habit of Lao Han, a villager in Wanzihe Village, Chengguan Town, Xinmi City, Henan Province, to promote fairness through openness, promote the standardization and institutionalization of the operation of small and micro power, open his mobile phone, log in to the regulatory cloud platform APP, check the village accounts, and see the receipt of pension and farmers' subsidies. "We are all supervisors. Let's see if we feel at ease, and we can put forward any comments at any time!" The APP that Lao Han logged in is the "sunshine and openness" supervision cloud platform developed and built by the Xinmi Commission for Discipline Inspection. The platform has set up four major systems, including big data analysis and administrative power supervision, and 13 sectors, including people's livelihood and enterprise related funds. It has established an open publicity system covering 350 administrative matters of 51 units. It has moved people's concerns from "behind the scenes" to "in front of the stage", making it more transparent, convenient to query, and more effective to supervise. Since this year, the number of visitors to the platform has exceeded 1.19 million. The untimely and opaque disclosure of information at the grass-roots level and the blind spots in the supervision of power operation are important reasons for the emergence of grass-roots contradictions and the breeding of corruption. It is an important consideration to establish an information supervision platform system to solve the problem of information disclosure by technical means, standardize the operation of power of small and micro enterprises, and strengthen the supervision of grass-roots public officials. Rural collective "three capital" (capital, assets and resources) is a prone area for grass-roots cadres to violate disciplines and laws. According to the relevant person in charge of the Hanjiang District Commission for Discipline Inspection in Yangzhou City, Jiangsu Province, some village collectives' "three kinds of capital" are unclear, unclear and ineffective. The transparency of village affairs and the participation of the masses are low, and there is a lack of effective supervision over the power of village cadres. In response to these problems, the Hanjiang District Commission for Discipline Inspection has built a "three capital" informatization supervision platform to achieve trace and standardized management of financial reimbursement, approval and other business processes, and achieve the full supervision of asset resources from registration, lease, inventory, maintenance and disposal. In the work practice of building the "three capital" supervision platform, all localities actively use new technologies such as big data and blockchain to find problems intuitively and efficiently, realize active and accurate supervision, and improve the quality and efficiency of supervision. The Commission for Discipline Inspection of Xishan District, Kunming City, Yunnan Province explored a new mode of "blockchain+" three capital "supervision", made public the information and data related to collective "three capital" on mobile phones and computer terminals, and fixed important data with "blockchain" technology to achieve on chain operation, on chain certificate storage, and on chain ownership. At present, the community collective "three capital" upgrading supervision platform in Xishan District has been officially put into use, and the monetary funds and creditor's rights of 504 collective economic organizations in the district
