Exxact Blockchain Servers Features

FULLY TURNKEY

Each solution is validated and tested to provide immediate use and the fastest time to deployment.



FASTEST LEAD TIMES

We have years of experience and a proven track record of manufacturing and distributing computing systems internationally.



LARGE DEPLOYMENTS

Our knowledgeable engineering staff can develop solutions and provide support for Blockchain nodes or storage racks.



HIGH AVAILABILITY

Exxact Blockchain Systems offer the highest reliability and availability to ensure your nodes are resistant to downtime.



OPTIMIZED SYSTEMS

EEngineers can optimize systems and servers for Bitcoin full nodes, or Nodes to run Hyperledger for private Blockchains.



SCALABLE SERVERS

Exxact Blockchain Servers can scale from small consensus node deployments, to large racks and clusters for multi party consensus and massive Blockchain storage operations.



What is a Full Node? (Bitcoin)

Full nodes download every block and transaction and check them against Bitcoin's consensus rules. Here are examples of consensus rules, though there are many more:





Blocks may only create a certain number of bitcoins. (Currently 12.5 BTC per block.)



Transactions must have correct signatures for the bitcoins being spent.



Transactions/blocks must be in the correct data format.



Within a single block chain, a transaction output cannot be double-spent.

If a transaction or block violates the consensus rules, then it is absolutely rejected, even if every other node on the network thinks that it is valid. This is one of the most important characteristics of full nodes: they do what's right no matter what. For full nodes, miners actually have fairly limited power: they can only reorder or remove transactions, and only by spending a lot of computing power. A powerful miner is able to execute some serious attacks, but because full nodes rely on miners only for a few things, miners could not completely change or destroy Bitcoin.





Why Run a Full Node?

Running a full node is the only way you can use Bitcoin in a trustless way. You will know for sure that all the rules of Bitcoin are being followed, for example that no bitcoins are spent not belonging to the owner, that no coins were spent twice, that no inflation happens outside of the schedule and that all the rules needed to make the system work (e.g. difficulty) are followed. Full nodes are currently the most private way to use Bitcoin, with nobody else learning which bitcoin addresses belong to you. Full nodes are the most secure way to use Bitcoin, they do not suffer from many attacks that affect lightweight wallets.

Hyperledger Architectures for Private Blockchain

1All Hyperledger projects follow a design philosophy that includes a modular extensible approach, interoperability, an emphasis on highly secure solutions, a token-agnostic approach with no native cryptocurrency, and the development of a rich and easy-to-use Application Programming Interface (API). The Hyperledger Architecture WG has distinguished the following business blockchain components:

CRYPTO ABSTRACTION

Allows different crypto algorithms or modules to be swapped out without affecting other modules.

CONSENSUS LAYER

Responsible for generating an agreement on the order and confirming the correctness of the set of transactions that constitute a block.

SMART CONTRACT LAYER

Responsible for processing transaction requests and determining if transactions are valid by executing business logic.

POLICY SERVICES

Responsible for policy management of various policies specified in the system, such as the endorsement policy, consensus policy, or group management policy. It interfaces and depends on other modules to enforce the various policies.

COMMUNICATION LAYER

Responsible for peer-to-peer message transport between the nodes that participate in a shared ledger instance.

IDENTITY SERVICES

Enables the establishment of a root of trust during setup of a blockchain instance, the enrollment and registration of identities or system entities during network operation, and the management of changes like drops, adds, and revocations. Also, provides authentication and authorization.

DATA STORE ABSTRACTION

Allows different data-stores to be used by other modules.

APIS

Enables clients and applications to interface to blockchains.

INTEROPERATION

Allows different data-stores to be used by other modules.
