We want to create a cenarios where third node modifies block information on node two. &nbsp;We have following questions.<br /> <br /> 1. Does multichain detect that information is tampered?<br /> <br /> 2. As a user of the blockchain how is the tampering is made known to the node two?<br /> <br /> 3. Is there a API to modify block information by node three?<br /> <br /> It would help if you share these information. https://www.multichain.com/qa/5180/altering-block-information Fri, 26 May 2017 13:23:58 +0000
