A brief overview of our technology

How It Works


At Commons Impact, our core values are ensuring security, privacy and fully decentralized communication. Using these principles, we build sensors and software to monitor noise pollution and store noise events securely on IPFS.

At each noise site, we deploy sensors that automatically form a local mesh network and capture noise events thousands of times a second and compute the average sound level in dB(A) units.


The business (or agent for the noise offender) visits Commons Impact website or smartphone app to initiate the contract. Key information collected will be the address of the business (used to establish GPS position) and maximum allowable noise readings in Decibels (db) by timezone throughout day. The business will have the option to stipulate if they would like noise readings monitored by the Commons Impact smartphone app or a noise consultant. If a consultant is selected the business will nominate a proposed consultant from a list of recommended consultants on the Commons Impact website. If there are no consultants listed for their geographic region the default will be smartphone app monitoring. If there is more than one consultant for their area the business will be required to nominate a minimum of 2 consultants.


Once the contract is initiated it is listed as an active contract. Nearby residents will be able to request to be added to the contract and a notification automatically sent to the business. If the resident is within the specified proximity of the business they will be automatically added as a 'Beneficiary' to the contract. Requests which come from outside the specified proximity zone (which might also come from a local authority for access to 'Monitor' the contract) must be approved by the contract initiator. If the contract involves an external noise consultant they will be added by the contract initiator with 'Collector' status. This status will also be automatically applied to residents under the smartphone app option.

  • Initiator - business owner (or agent)
  • Beneficiary - resident (or other parties impacted by noise)
  • Monitor - local authority (or other enforcement agency)
  • Collector - data provider (either noise consultants or smartphone app users)


Noise data collection can commence at any time but only becomes live once the contract start date is reached. Data will initially be verified using a tolerance algorithm on a decentralised application layer such as IPFS to minimise calculations that need to be performed within the smart contract thus minimising gas costs. Data which is over tolerance (i.e. exceeds decibel levels set by the project initiator for the time of day) will be combined with a proximity algorithm to determine the payout for each beneficiary. All data collected will also be hashed and sent to the blockchain in packets to enable subsequent verification by GPS data point.



Commons Impact will be the most affordable noise monitoring solution in the market. Commons Impact contracts will be able to be initiated for a small monthly fee in contrast to current noise monitoring which requires specialist equipment and acoustic consultants or engineers costing thousands (and in some cases hundreds of thousands) of dollars. Often each party will engage their own noise consultant, Commons Impact will enable parties to mutually agree on a noise consultant or completely avoid the need for a consultant by agreeing to use smartphone monitoring.


Noise readings are submitted to the blockchain and verifiable using blockchain reporting tools. This ensures trust in the system with results shared instantly between relevant parties rather than the current situation where the noise consultant report is produced days or weeks later.


Commons Impact will provide a mechanism where businesses can interact directly with impacted parties (i.e. nearby residents) thus creating a 'social contract with financial compensation should conditions not be met. This will enhance the reputation of the business and decrease the need for monitoring by local authorities, enforcement agencies and/or noise consultants. Noise monitoring in some situations will also be able to done directly by individuals using the Commons Impact smartphone app, providing them with enhanced satisfaction with results.


Businesses will be able to initiate a smart contract in minutes specifying target noise levels by time of day. Nearby residents (or other impacted parties) will scan for relevant contracts in within proximity and requested access to the contract. Once access is approved they can vote on a preferred noise consultant or selectto self monitor using the Commons Impact smartphone app (if this option is enabled).


Impacted parties will receive financial compensation within minutes should noise parameters be exceeded. This provides an incentive to businesses to ensure noise levels are acceptable and compensation to citizens for their loss of quiet existence. Currently impacted parties are very rarely compensated and the response by local authorities or enforement agencies is often not timely enough nor does it provide a specific enough outcome for impacted parties.
