PrivateStack

Now in Kaleido, we provide decentralized solutions for every level of participation seen in enterprise blockchain networks:

• High investment members who are the trust anchors of the network: Can run nodes in their own private data center, or private cloud VPC, have full control over every aspect of the software and infrastructure stack, can demonstrate infrastructure decentralization of the network validators, and meet the strict IT security requirements with tech designed for enterprise.
• The network operator entity or board of trustees: Make the blockchain plumbing a simple part of the application stack, allowing new members to onboard while retaining a fully interconnected business network - including with privately hosted nodes, retaining visibility of the health of the infrastructure, and retaining control of permissioning and governance. 
• Full participation network members: Have your own fully managed blockchain node in seconds in AWS or Azure, run multi-region, multi-cloud with fully-managed infrastructure, enterprise grade high availability (HA) and disaster recovery (DR), key management — including AWS & Azure cloud HSMs and HashiCorp Vault, REST APIs and Event Streams to integrate to your existing apps & infra, off-chain private file and data transfer, with strong identity and encryption.
• The “long tail” of network participants: Connect to a multi-tenant node without needing any IT investment, secure signing keys and data dedicated to you, gain visibility into how blockchain makes the business network decentralized.
• End users: Secure connectivity into the network (OAuth / Open ID connect), with custodial or non-custodial key management.

The PrivateStack software package itself provides you with two key components:

1. PrivateStack Network Bridge

Combines forward & reverse proxies, secure network bridging via industry standard DMZ friendly networking, and dynamic configuration management. Designed to put you in full control of your network security, while retaining bi-directional connectivity to and from the whole business network.

2. PrivateStack Agent‍

Simplifies the creation of your private self-managed node into a single command. Provides a secure API to bootstrap your node into the business network, and share its public identity with other nodes in the same Kaleido environment. A cut-down version of the agent we run for nodes in the Kaleido fully-managed platform, it provides your organization enough with enough connectivity to ease on-boarding, without compromising the integrity of your private keys and data.

We’ve been able to keep the OSS core blockchain protocol itself untouched and able to support all protocols, regardless of their choice of networking and consensus algorithm. Today we support: Corda, Hyperledger Besu + Orion private transaction manager, Quorum + Tessera private transaction manager, and Go Ethereum.
