CRONCAT, Decentralized Scheduling for Blockchain Transactions. Schedule tasks for any contract. Automate anything your contract needs. Use the age old standard crontab spec to annotate time intervals. Extended to support blockchain consensus timing. Specify once or many times a task can run. Tasks can execute as long as they have budget. All tasks are triggered by a network of croncat agents. Your task parameters are sandboxed away from any tampering. Tasks pay a small fee for future timing. This rewards agents for staying diligent and doing transactions on your behalf.
