(iii) digitally sign the digital asset to generate a signed asset, (iv) submit, at the first time of asset capture, a first transaction to establish provenance of the captured digital asset based on the first cryptographic hash, (v) compute a second cryptographic hash for first metadata captured with the digital asset at the first time of asset capture, (vi) rehash the signed asset with the second cryptographic hash to generate a stored asset, and (vii) submit a second transaction including the second cryptographic hash, wherein a second transaction entry includes a registration of the second transaction; an electronic registry configured to (i) receive the first transaction from the electronic processing device substantially at the first time of asset capture, (ii) register the first transaction on an immutable distributed digital ledger as a first transaction entry including the first cryptographic hash, and (iii) append the second transaction entry on the immutable distributed ledger; an electronic network configured to receive, at a second time subsequent to the first time of asset capture, a combination of the signed asset and the first cryptographic hash from the electronic processing device and distribute the combined signed asset and first cryptographic hash to an electronic media viewer of the ecosystem as registered digital content; and wherein the electronic media viewer is configured to (i) verify, with the electronic registry over the electronic network, the registered digital content as verified digital content, and (ii) enable viewing of the verified digital content, wherein the electronic registry is further configured to, upon distribution of the combined signed asset and first cryptographic hash by the electronic network, append a third transaction entry to the immutable distributed ledger. ### Claim 2 (depends on 1) The ecosystem of claim 1, wherein the electronic network includes the Internet. ### Claim 3 (depends on 1) The ecosystem of claim 1, wherein the electronic media viewer is one of a client application, a browser, an audio display device, a visual display device, and an audiovisual display device. ### Claim 4 (depends on 1) The ecosystem of claim 1, wherein the electronic registry comprises a server including a secure database within the immutable distributed digital ledger. ### Claim 5 (depends on 4) The ecosystem of claim 4, wherein the immutable distributed digital ledger includes at least one blockchain. ### Claim 6 (depends on 4) The ecosystem of claim 4, wherein the electronic registry is further configured to provide a certification for the signed asset based on the first cryptographic hash registered in the first transaction entry. ### Claim 7 (depends on 4) The ecosystem of claim 4, wherein the electronic registry is further configured to receive a transaction report from the electronic network for one or more of a plurality of distributions of the combined signed asset and first cryptographic hash. ### Claim 8 (depends on 1) The ecosystem of claim 1, wherein the electronic processing device is further configured to (ix) process the signed as set by encryption to generate an encrypted asset, and (x) compute a third cryptographic hash for the encrypted asset. ### Claim 9 (depends on 1) The ecosystem of claim 1, wherein the electronic processing device is further configured to rehash the stored asset with a third cryptographic hash computed for second metadata different from the first metadata. ### Claim 10 (depends on 9) The ecosystem of claim 9, wherein the electronic processing device is further configured to submit a third transaction to the electronic registry for appending onto the immutable distributed digital ledger as a fourth transaction entry. ### Claim 11 An electronic device for a digital asset ecosystem including an electronic registry, an immutable distributed digital ledger, an electronic network, and an electronic media viewer, the electronic device comprising: an electronic capture unit configured to capture a digital asset at a first time of asset capture; a processor; and a memory device including computer-executable instructions therein, which, when executed by the processor, cause the processor to: compute a first cryptographic hash for the digital asset captured by the electronic capture unit, and for first metadata related to the digital asset at the first time of asset capture;
