PoH is our decentralized data integrity protection service. Since it relies on our AnuuTech Network, it’s able to provide robust security, exceptionally fast transactions (via trusted connections), and offers a fully customizable consensus. Using PoH will eliminate the need to store data on the blockchain so as to guarantee both its existence and its integrity. It will also make the existence of technologies such as our PRIVATE CHAINS possible. Ultimately, PoH is an integral part of our solution to separate data validation, data storage and data integrity. We have built our PoH technology on top of the AnuuTech Network. PoH can operate as a decentralized data integrity protection service while running on our node network. Ultimately, PoH provides a safe, fast, and extremely reliable service to anyone seeking to protect their data, regardless of data type and data storage. --------------------------------------------- We are currently deep in our Seed round actively looking for investors.

4. PoH consensus
What is PoH PoH stands for Proof of Hash, it is a network consensus protocol that provides trustable unalterable
proof of the existence of a data subset at a given moment in time.
The PoH consensus protocol is not used to validate any data, it is only used to provide proof of integrity and
existence of (any type of) data.
Average checkpoint
An average checkpoint gets lots of inputs from various users
and these inputs are inseparable from each other. So each
unique original input helps creating a more secure final hash.
These various data inputs are mixed and protecting each
other.
For example User 1 creates a data fingerprint using its own
digital signature. If User 2 does the same and uses these
two inputs, the system creates a third fingerprint and then
this third fingerprint makes it impossible for User 1 and User
2 to repeat the same process using other input.

5. The node network
PoH relies on a network of trusted nodes executing the various tasks that make up the consensus protocol. In the
AnuuTech network the nodes are divided in 3 different levels each responsible for a part of the consensus protocol.
In the AnuuTech network the third level of nodes is the collection layer, users that want to use the PoH service will
interact with the nodes on this layer. The second level of nodes is the aggregation layer where all the data collected
by the third layer is compressed into smaller packages. This layer also serves as a barrier between the third layer
which is accessible by the network users and the first layer where the eventual consensus is reached. This will help
prevent the possibility for network users to interfere with the consensus process. In the first layer the nodes will reach
a consensus on the data collected by the third layer and aggregated by the second layer, and the result of the
consensus will be made available for the rest of the network. The operations that need to be executed are done by
virtual “checkpoints”hostedonthenodenetwork.
The hosting of each checkpoints is assigned in a pseudo random fashion, partially based on the result of the previous
outcome of the consensus round and the certificates issued to the nodes, after each consensus round. Multiple
checkpoints can be assigned to the same physical nodes should there not be enough physical nodes for all the
checkpoints.

6. How does it work?
Consensus phase
Level 3 - Collection phase
When a user wants to use the PoH service, they will present a subset of data to the third node level. The checkpoint
selected to handle this request is directly related to the data. The checkpoint will create a time stamped data finger-
print for the data based on the checkpoints unique certificate and the current network time, add this time stamped
data fingerprint to its collection and the shared temporary storage for the current time period, and provide this
fingerprint to the network user. The user (1) will present this time stamped data fingerprint to a second checkpoint
(5), selected based on the fingerprint , on the third level which will verify if the time stamped data fingerprint was
created by the correct checkpoint (3) on the third level and if it exists in the shared storage. The number of secondary
checkpoints that will collect/verify the time stamped data fingerprint can vary depending on the consensus rules for
the network. All checkpoints on the third level will collect the timestamped data fingerprint (4) they either generated
or veried for the duration of the specic time period (n).
Once a user (1), receives a timestamped data fingerprint , they will have a temporary proof of data integrity, however,
to get full confirmation the master hash for the time period of the time stamped data fingerprint needs to be added
to the shared storage for the PoH consensus protocol and the time stamped data fingerprint needs to be used in the
calculation of the master hash. The time required for full confirmation is n x 4.

7. Level 2 - Aggregation phase part 1
All checkpoints on the third level will aggregate (6) the time stamped data fingerprints they collected during the time
period (n) and hash the collection. The checkpoints on the third level will send the collection hash (7) to a checkpoint
on the second level, selected based on the collection signature. The checkpoints on the second level will verify (8) the
consensus for the time stamped data fingerprints included in the collection and provide a collection fingerprint,
based on the unique certificate of the second level checkpoint and the current network time. The checkpoint on the
second level will add this collection (9) fingerprint to its collection for the current time period and the shared storage
and provide this collection fingerprint to the checkpoint on the third level that had sent the collection. The check-
point on the third level will send the collection fingerprint to a second checkpoint on the second level (10), selected
based on the created collection fingerprint, which will verify if the collection fingerprint was created by the correct
checkpoint on the second level and if it exists in the shared storage. The number of secondary checkpoints that will
collect/verify the collection fingerprint can vary depending on the consensus rules for the network.
All checkpoints of the second level will collect all the collection fingerprints (11) they either created or verified for the
duration of the specific time period (n).

8. Level 1 - Aggregation phase part 2
All checkpoints on the second level will aggregate the collections they collected during the time period (n) and hash
of the new collection (12). The checkpoints on the second level will send the new collection hash to a checkpoint on
the first level, selected based on the new collection signature. The checkpoints on the first level will verify the consen-
sus for the collections included in the new collection and the consensus for the digital fingerprints included in the
collection, (13) and provide a consensus fingerprint, based on the unique certificate of the first level checkpoint and
the current network time. The checkpoint on the first level will add this consensus fingerprint to its collection for the
current time period and the shared storage and provide this collection fingerprint to the checkpoint on the second
level (14 Page 9) that had sent the new collection. The checkpoint on the second level will send the consensus finger-
print to a second checkpoint on the first level, selected based on the created consensus fingerprint, which will verify if
the consensus fingerprint was created by the correct checkpoint on the first level and if it exists in the shared storage
(15). The number of secondary checkpoints that will collect/verify the consensus fingerprint can vary depending on
the consensus rules for the network.
All checkpoints of the first level will collect all the consensus fingerprints they either created or verified for the dura-
tion of the specific time period (n) (16).

10. Master hash phase
Level 1 - Signing phase round 1
All the checkpoints of the first level (17) are ordered in a pseudo random fashion, based on the previously generated
masterhash, in a number of groups with equal members.
Within each group all the checkpoints will have a specific order as well.
All the groups will work simultaneously to generate an aggregated collection of unique time stamped data finger-
prints included in all the new collections for which the checkpoints of the first level that are part of the group either
created a consensus fingerprint or verified a one during the previous phase. The first member of the groups will have
an allotted time frame to add all the unique time stamped data fingerprints included in the new collection for which
it created or verified a consensus fingerprint during the previous phase to the groups shared storage and sign the
entries. The other checkpoints of the groups will sync with the shared storage and add the entries to their collection if
they can confirm the consensus for each time stamped data fingerprint. After the allotted time frame for the first
checkpoint has expired, the second checkpoint of the group (18) will add all the unique time stamped data finger-
prints, included in the new collections for which the checkpoint either created or verified a consensus fingerprint, and
which have not yet been added to the group’s shared storage during its allotted time frame and sign the entries.
Again, the remaining checkpoints (19) of the groups will sync with the shared storage and add the entries to their
collection if they can confirm the consensus for each digital fingerprint. Next (20) the third checkpoint will do the
same followed by all other checkpoints in the group.

11. Level 1 - Signing phase round 2
When all checkpoints have added their digital fingerprints to the group’s shared storage, each member of the first
group (I) will send their collection of digital fingerprints to their counterpart in the second group (G1C1 -> G2C1;
G1C2->G2C2; …). The checkpoints of the second group (II) will compare the collection of digital fingerprints they
each received with the rest of the group. If they received the same, they will continue with the collection they
received, if not they will continue with the collection with most digital fingerprints for which they can confirm the
consensus. The checkpoint of the second group will verify the consensus for each digital fingerprint and add the
collection of digital fingerprints for the second group generated in the previous phase. The combination of digital
fingerprints collected by the first group and those by the second group is sent to the counterpart in the third group
(G2C1->G3C1; G2C2-G3C2; …). The checkpoints of the third group (III) will compare the collections they each received
with the rest of the group. If they received the same, they will continue with the collection they received, if not they
will continue with the collection with most digital fingerprints for which they can confirm the consensus. The check-
point of the second group will verify the consensus for each digital fingerprint and add the collection of digital
fingerprints for the third group generated in the previous phase. The combination of digital fingerprints collected by
the second group and those by the third group is sent to the counterpart in the fourth group (G3C1->G4C1;
G3C2-G4C2; …). Next the fourth group (IV) will do the same followed by the other groups.
21. Repetition of step 20
the remaining checkpoints of the groups will sync with the shared storage (19) and
add the entries to their collection if they can confirm the consensus for each TSDFP.
22. Repetition of step 20
the third checkpoint of each group will add the unique TSDFPs

Level 1 - Adding phase
When the last group has finished adding the digital fingerprints for the last group. The checkpoint of the last group
will compare their collections with each other and the checkpoint with the highest priority will create a master hash
with all the digital fingerprints for which the consensus could be confirmed. This checkpoint will present the master
hash to the controllers of the location in the decentralized storage selected to store the master hash for that time
period. All the controllers verify if the checkpoint presenting the master hash has the highest priority in the last group
and verify the created master hash before the master hash is stored. If one of the controllers rejects the master hash,
new controllers will be selected pseudo-randomly. And the checkpoint with the highest priority will repeat the
process. If no master hash is added within the pre-defined time frame, an empty hash will be added.

14. How does PoH provide trustable proof
The digital fingerprint created by the level 3 checkpoints uses the hashed value of the data requesting the PoH
integrity protection, the current network time and the unique certificate of the level 3 checkpoint for that time
period. This way the digital fingerprint provides 3rd party verification of the data content for the data at the moment
the digital fingerprint was requested. The master hash is a hash value created from all the digital fingerprints for that
time period and provides proof for the digital signature's existence in that time period. Only 1 master hash can exist
for each time period and the master hashes are also linked to each other much like the blocks in a regular block
blockchain.
Every user will sync with the network the moment they connect to the network adding all the master hashes to their
chain.
It will be impossible for a user to change the data protected by a digital fingerprint after the master hash for that time
period has been created.
