Better On Blockchain explores how companies or business models benefit from decentralization. In episode two, Reach CEO Chris Swenor and CTO Jay McCarthy discuss whether office suites like Office 365 and Google Workspace would be better served on blockchain.

3. What Are Office Suites?
Existing Business Model: Software as a Service
● Core Functionality
○ Create Documents
○ Share Files
○ Cloud Collaboration
Add-on and Plugin Galleries and Marketplaces
● Core Components
○ Word Processor
○ Spreadsheet
○ Presentation System

4. Understanding the role of commitments:
● Rather than storing the data itself, you can store a commitment for that data.
○ Commitments are, in essence, a probabilistic guarantee that the data you’re looking for is stored somewhere
on the network.
○ There are a number of ways to generate a commitment (e.g. a signature or checksum).
○ Algorithms like MD5 or SHA256 take an arbitrarily large amount of data and compress it down to into
something very small. Unlike ZIP files, the data that makes up a commitment cannot later be extracted.
○ This “one-way” compression generates a unique value (or “commitment”) by which the data can be identified.
○ Then, instead of storing that arbitrarily large quantity of data on each node, you’re only asked to store the
commitment.
○ The commitment is used in retrieval to identify the original files.
Building it on Blockchain

5. Handling decentralized file storage:
● You could implement something similar to Napster such that, when trying to retrieve your data, you search
through different nodes on your network until you find one that has what you’re looking for.
● You could tie this to the blockchain and let users pay to replicate their data by paying coins in the token of the
blockchain.
● However, this strays too far from the typical conceptualization of “blockchain storage”. The happy medium would
be to store hashes on a public chain like Algorand or Ethereum and pairing it with networks like Siacoin or
Arweave which are specifically built for decentralized data and file storage.

7. Pros
● With each save, users can effectively “sign” their work in a way which is more secure and harder to falsify than
esignatures on Adobe eSign or DocuSign. Each signature is accompanied by their digital fingerprint. That
fingerprint serves as a record of trust that that user is who they say they are.
● Hashing algorithms are useful because you can store a very small amount of data on-chain to certify that this
other data that’s stored off-chain is the right stuff.
● You don’t have to deal with huge packages of add-ons or plugins (which exist, in large part, to avoid paying a
transaction fee for each individual component).
● It’s easier to attribute content or ideas to their creators (which could clear up a number of headaches in
intellectual property law).
Pros & Cons of Decentralization

8. Cons
● Storage can be costly depending on what chain you use.
● Hashing algorithms aren’t useful for backing up your data.
● Blockchain adds value to some features, but not others; i.e. a “purely” decentralized office suite can’t stand on
its own relative to existing off-chain options.
