How to create private payment networks with Hyperledger Besu

This is your high level guide to creating a private payment network. You create these because you want instant trade settlement with full allocation clarity, and you do it to avoid other more costly traditional event based solutions, like Swift.

Private payment networks are taking the world by storm. We’ve now left the innovation lab, and business benefits are being realised with production ready software. Included in the stack we typically find Hyperledger Besu, an Ethereum node implementation I’ve blogged about previously.

First, let’s talk about what we typically don’t find in such private blockchain networks: Native cryptocurrency. These tokens, like bitcoin or ethers, exist to enable transactions to take place on public permissionless blockchains, like the Ethereum mainnet. They also serve as the incentive mechanism for node operators.

While they can be used for things like collateral in DeFi applications, private networks don’t normally have a native token. And if they exist, they are often without value, functioning only as a transaction spam prevention mechanism. This is a bit like how native cryptocurrencies on testnets operate. They are needed to perform actions, but they are given away for free or in exchange for managing the network.

Instead of managing private networks through native token incentives, private networks are managed through governance structures.

3 Steps to creating a private payment network 

Step 1: Private blockchain network governance

Running a private network means agreeing on the rules. The rules are likely to state the criteria required for being allowed to join the network. These are followed up with further rules around the responsibilities.

An example responsibility would be to run one (or more) instances of the Hyperledger Besu node across servers managed by the participating member. They’d need to commit to a certain amount of availability and keep up with mandatory updates. They’d also need to agree on the configuration, so that the right protocol parameters are set.

Not having members run their own node compromises the decentralisation of the network. In the worst case scenario, it turns it into a centralised database that can be manipulated or shut down by the operator.

As an enterprise ready Ethereum node implementation, this is where Hyperledger Besu shines. It is flexible enough to allow for customisations, through plugins, enabling unique features within the private network. It also comes out of the box with support for private transactions and consensus mechanisms that are well suited for such networks.

The governance framework then helps define the approach to this, among other things.

Step 2: Securing monetary value

Creating a private network and then issuing tokens on it is just as easy as on a public network.

But how do you secure the value of these tokens? We likely don’t want these tokens to be priced based on just supply and demand. Instead, we want them to represent some underlying asset or currency.

On public blockchain networks we have stablecoins. These are tokens usually pegged to the US dollar, making 1 token equal to 1 USD. And they often maintain this value by having some entity hold the corresponding currency as collateral in one or more banks.

That works, but it’s at the mercy of the safety of the banks holding the assets. We’ve recently seen this cause concern with the collapse of Silicon Valley Bank causing USDC to temporarily depeg. This is likely a risk not tolerated within a private network, so the gold standard (no pun intended) is for the collateral to be held by the relevant central bank.

An example would be if we wanted to have a token representing GBP. Within this framework we’d then need to work with the Bank of England, have them hold the collateral, and the owners of that collateral would receive tokens in return. The owners can then exchange the tokens with other network members or redeem the tokens for the underlying cash.

This minimises risk, as we know the central bank can deliver the underlying. But it’s also a very involved structure. While a solid framework, it takes time to establish, and only really apply directly between banks.

Some might call these CBDCs, short for Central Bank Digital Currency. But the definition of CBDCs often includes central banks directly exposing this to retail. This isn’t the case for private networks.

Step 3: Enabling better money

While the above talks about banks and central banks, it doesn’t always need to be just that. You can also use Hyperledger Besu to create private networks between well established customer relationships. Imagine a logistics chain with many companies. Each company needs to pay the other and get paid by the next as the inventory passes through the various steps.

Throughout that process, the various companies involved have various levels of exposure to the other companies. While we often talk about just in time delivery of products (something done to reduce inventory and costs), private blockchain networks can allow for the same with monetary value.

Private blockchain networks can give us a better and more up to date view on financial transactions, and we can leverage features of smart money. Smart money, or programmable money, can reduce risk and delays by automating transactions, helping us maintain counterparty risk within defined parameters.

Through this, and the shared ledger represented by the private blockchain network, we can enable just-in-time value transfer that reduces capital lock-ups and speeds up settlement time.


Business partners, customers and suppliers, with products and services that are exchanged benefit from private blockchain networks. This is because they enable a better and more efficient flow of transactions and value.

Private networks can remove ambiguity around settlement and allocation, reduce capital lock-up and help move money into a just-in-time mindset. Programmability of money allows for smart money, which in turn is integrated with risk parameters and boundaries that help automate flows and reduce errors.

These private blockchain networks are supported by enterprise grade Hyperledger Besu blockchain node software. At Web3 Labs we’re experts at running and maintaining these. We offer multiple tiers of support designed to meet your unique blockchain technology needs from development to production.
