Prevention of majority attacks

A method, comprising:

• connecting, by a participating blockchain (BC) node, to a blockchain network configured to store a plurality of packages;
• selecting and downloading, by the participating BC node, a package containing a random code variant identified by a unique identifier (ID);
• executing, by the participating BC node, the package to calculate an outcome associated with the variant ID;
• receiving, by the participating BC node, votes on outcomes associated with the variant ID and votes on outcomes associated with different variant IDs from other nodes of the blockchain network;
• and
• analyzing, by the participating BC node, the votes to determine if the votes on the outcomes associated with the variant ID are different from the votes on the outcomes associated with the different variant IDs.

A non-transitory computer readable medium comprising instructions, that when read by a processor, cause the processor to perform:

• connecting to a blockchain network configured to store a plurality of packages;
• selecting and downloading a package containing a random code variant identified by a unique identifier (ID);
• executing the package to calculate an outcome associated with the variant ID;
• receiving votes on outcomes associated with the variant ID and votes on outcomes associated with different variant IDs from other nodes of the blockchain network;
• and
• analyzing the votes to determine if the votes on the outcomes associated with the variant ID are different from the votes on the outcomes associated with the different variant IDs.
