Establishment of consortium blockchain network

A method, comprising:

• endorsing a first node, including:
• storing pre-determined code of the pre-determined type of blockchain protocol code in a trusted execution environment (TEE) of the first node;
• storing, in the first node, a first pre-determined membership list of a consortium;
• and storing, in the first node, a first authorization associated with the pre-determined type of blockchain protocol code;
• receiving, from a plurality of prospective members of the consortium:
• a plurality of membership lists, and a plurality of authorizations from the plurality of prospective members of the consortium;
• determining that the plurality of membership lists from the plurality of prospective members of the consortium match the first pre-determined membership list;
• in response to determining that the plurality of membership lists from the plurality of prospective members of the consortium match the first pre-determined membership list verifying with TEE attestation that nodes associated with prospective members of the consortium store the pre-determined type of blockchain protocol code that matches the first authorization;
• and
• bootstrapping a consortium network with the prospective members as members of the consortium network.

A processor-readable storage medium, having stored thereon processor-executable code that, upon execution by at least one processor, enables actions, comprising:

• determining that a plurality of membership lists from plurality of prospective members of a consortium match a first pre-determined membership list;
• in response to determining that the plurality of membership lists from the plurality of prospective members of the consortium match the first pre-determined membership list, verifying, via trusted execution environment (TEE) attestation, that nodes associated with the plurality of plurality of plurality of prospective members of the consortium store a pre-determined type of security protocol code that matches a first authorization;
• and
• in response to verifying that the nodes associated with the plurality of plurality of plurality of prospective members of the consortium store the pre-determined type of security protocol code that matches the first authorization, bootstrapping a consortium network with the plurality of prospective members as members of the consortium network.
