Active customers in finance, enterprise, insurance and energy

First French Blockchain startup to raise 600k Euros, currently fundraising for Series A

Our world is governed by processes

Which are managed in databases

That exist in silos

Everything is a process

Yet, today’s workflows are built as “Black Box” systems prone to :

• Asymmetric Information

• Synchronization & Complexity

• Exposure to Private Data

Blockchains Streamline Processes• Blockchains streamline

processes through timelines

• Timeline is established by consensus

• Data which is contained in a blockchain is secure and transparent

Blockchain Features

• Timeline by consensus

• Cryptocurrencies & Tokens

• Transactions & Multiparty Sigs

• Smart Contracts

Blockchain AnatomySecure chain of dataProvides traceability, transparency, replay, immutability

TransactionsTransfer of ownership of assets, data notarization, tokenization

ConsensusEstablish independent validation between multiple parties (trust engine)

Blockchains provide an objective proof of the existence of data in time.*

New Paradigm: Trust Networks

Data immutability

Transparency between stakeholders

Independent auditability

First Use Case: Bitcoin

• Digital cash

• Store of value

• Payment mechanism

• Instant settlement

“A purely peer-to-peer version of electronic cash would allow online payments to be sent directly

from one party to another without going through a financial institution. ”

–Satoshi Nakamoto

Bitcoin AnatomyLedger of transactionsBlocks contain transactions which were sent to the network within the last 10 min

TransactionsTokens (Bitcoins) are transparently transacted between participants of the network

ConsensusMiners compete to preserve integrity of the ledger and are incentivised for this work

Blockchains enable Trust Networks

What if we bring the blockchain to the business workflow?

Objective: Digital Notary

By storing a digital fingerprint, or hash, in a blockchain transaction, any data scientist can prove the existence of data in time.

Trust NetworksTrust Networks leverage actors in consensus to verify subjective facts such as “Does Atma live in Mauritius?”

Proof SystemsA prover must convince the verifier of a secret or fact, within a reasonable doubt, through a protocol of exchanging messages.

Trusted WorkflowsDigital facts supported by data integrity, proof of anteriority, non-repudiation and contextual proof

Integrating Proofs Into Processes

• Proof of Process paper which describes how to integrate proofs into processes

• Ability to establish a complete Trust Network leveraging both objective and subjective proofs

Read the paper

Proof of ProcessA protocol that enables a prover to convince a verifier of the integrity of a process by sharing the proofs of each step.

Stratumn PlatformBuilt on an n-Tier architecture, our platform can be used to leverage proof systems to secure business workflows.
