As per https://internetofcoins.org/en/earlyholders:

AFTER MAKING ADDRESSES

When you have made 7 addresses using the blockchain systems above, please send them to us by e-mail to: distribution@internetofcoins.org

Please copy and include the following in your message.

TXID: {transaction ID's you used}
Omni: {public key}
Ethereum: {public key}
NEM: {public key}
Bitshares: {public key}
Counterparty: {public key}
NXT: {public key}
Waves: {public key}

Could someone please clarify how such submissions would be verified to ensure that the claimant is in fact the original contributor?
TXID-s are publicly visible, aren't they? I.e. - where in this equation is the proof of ownership of the contributor's private key?
Thx

HYBRIDs will be distributed to donators who registered their transaction with our crowdfund in the past three months. They can distribute them further after receiving them in July if they want to
