While this so-called "blockchain as a service" functionality is not new, the public blockchain options reflect a new willingness among enterprises to explore the technology As far back as 2016, companies such as Microsoft had helped coin the phrase "blockchain as a service" with the launch of its own blockchain sandbox with Azure cloud integration. Similarly, Blockdaemon's blockchain support platform lets enterprises spin up fully supported nodes starting at $249 a month, with part of the recent venture capital investment being used to subsidize adoption of the bitcoin and ethereum platforms down to a rate of $14.99 a month. Blockdaemon also plans to use the new capital to double the size of the company's engineering team from 10 to 20 in the next few months, resulting in a proportionate doubling of the corporate run-rate to about $100,000 a month.
