Blockchain vs Atomikos

How does blockchain compare to classical distributed transactions?

Blockchains and "classical" distributed transactions like from Atomikos offer similar solutions in some ways, with some important differences.

Why trust us?

We are distributed transaction experts (not specifically blockchain, but still). That is how we make money. The blockchain trend is important enough for us to follow-up on it and see what synergies are possible. So we do study the differences and similarities a lot. The table below outlines where we can complement your blockchain project.

Comparison table

Feature	Benefit	Atomikos	Blockchain	Remarks
Distributed consensus	All parties agree whether a change to the data is acceptable			For blockchain this applies to whether a block can be added to the history contained within the ledger. For classical transactions, this applies to any distributed update scenario so it's more general.
Target any data store	Can you choose the storage mechanism?			For blockchains, the ledger is the storage (by definition). Atomikos supports multiple types of data stores.
Crash recovery	Does the platform handle node outages?			Atomikos offers self-healing recovery to guarantee consensus even in the presence of crashes. For blockchains, this is not clearly specified and implementation-dependent.
Avoids duplicate transaction messages	In case of failures and retries, you don't want a transaction to happen twice			For blockchains this is implementation dependent - ask your vendor for details.
Avoids losing transaction messages	When you make a payment, you don't want it to get lost in cyberspace			For blockchains this is implementation dependent. To our knowledge, R3 is the only platform that currently avoids losing messages.

Our take

Blockchain is an important and interesting new phenomenon, but so far the only real use case seems to be digital currencies. Blockchain is more of a storage mechanism than a "transaction" mechanism since it registers the fact that transactions have happened. However, for this information to reach the blockchain, a lot of intermediate distributed transactions are needed where a solution like Atomikos can ensure that data is not lost, or no duplicates arise.

We expect to see private blockchain implementations rise as a mechanism for sharing facts among parties that trust each other. This will happen mostly in proof-of-concept implementations to test the waters. In such private blockchains, your blockchain platform may benefit from Atomikos in several ways:

• by using Atomikos to make sure that transactions make it to the chain, exactly-once (no losses nor duplicates)
• by using Atomikos to implement consensus with crash recovery and self-healing capabilities
