tissue trust assurance

The tissue trust assurance is based in the self asymmetric key pair generation, each cell generates it own keypair. As is the cell public key is not trusted, but as it join the tissue, the public key of this cell is assumed as trusted, as the cell is following the same DNA (enforced by the DNA blockchain).

All the blocks submitted to the DNA blockchain should be signed by a cell member of the tissue, if the block signature is not recognized the block is rejected. The only services the cell can present to the tissue are the services already contained in the tissue. To propose a new service, the DNA should be changed to add the service and the tissue should accept the change first.
