SatoshiPay partners with

Nov 12, 2017 · 6 min read

We are happy to announce our partnership with the Stellar Development Foundation (SDF). Starting with our next major release, we will use Stellar as the underlying cryptocurrency ledger of our nanopayment system. will generously credit each of our users 500 lumens. Yay!

A few months ago it became evident that Bitcoin’s original vision of a peer-to-peer electronic cash system is no longer viable for everyday transactions. Due to its wild success, stalling scalability measures and the subsequent network congestions, minimum amounts that can be sent over the Bitcoin network and transaction fees rose from under a cent to several EUR/USD per transaction. For SatoshiPay this meant we could no longer wait for Bitcoin to scale, but needed to look for a new blockchain or distributed ledger to migrate our nanopayment system to.

We looked at different options that are suitable for micropayments at our expected scale, did thorough due diligence and tested extensively for current production readiness — and concluded to make Stellar our default ledger.

Jed McCaleb, cofounder of on our decision and joint vision:

“We’re excited that SatoshiPay has selected Stellar as its primary ledger technology and look forward to inviting SatoshiPay users to the Stellar community. Cryptocurrencies and blockchain technology are facilitating open innovation and revolutionizing the payments space, and we’re thrilled to be working with SatoshiPay to help lead the way by making micropayments much faster and less costly than ever before.”

The Stellar advantage

Stellar also sports native asset token support, distributed exchange features and allows transactions to be routed through different currencies. On top of that there is a sophisticated multi-signature account architecture, time locks and batched operations — which enable simple smart contracts. This is ideal for our needs, and thanks to Stellar’s own version of the “Keep it simple, stupid” principle, it’s all easy to plug together.

Because in Stellar there is no mining or other verification work that might consume plenty of energy, server infrastructure to run the network is minimal and in terms of CO2 footprint it can be considered very environmentally friendly, especially when compared to proof-of-work based blockchains like Bitcoin or Ethereum.

We feel that apart from the solid technical advantages, SDF is without doubt also a very powerful and well connected business partner: Founded in 2014, is headquartered in San Francisco and received initial funding by the credit card payment processor Stripe. IBM recently announced to use Stellar in their blockchain banking platform. Stellar’s cryptocurrency Lumen currently has a market cap of €480m.

How SatoshiPay uses Stellar

In Bitcoin we used micropayment channels to save transaction fees and to speed up payments. Channels delayed payouts to publishers to up to a week. Because all Stellar transactions are final within seconds and cost next to nothing, we no longer need payment channels and will for the first time be able to settle all transactions in real-time and directly on the distributed ledger. This means now a publisher will irreversibly receive funds to their Stellar account within seconds after a consumer pays for content — true peer-to-peer nanopayments.

We will continue to generate the private keys that control consumer funds on the consumer’s device and never submit them to our servers, meaning we never directly control consumer funds, but merely act as a transaction broker. This also means that consumers still don’t need to create a login with us — one barrier to adoption less.

500 free lumens for each SatoshiPay user

SDF has agreed to grant these free lumens to our first 100,000 users, with an option to extend the program to more users later. Correct, at current XLM exchange rate this is over €1m in free credit to SatoshiPay users, and some guaranteed income for our publishers through content payments resulting from that. This is absolutely HUGE!

Multiple ledger support

Back in Berlin, our team was already working hard on replacing Bitcoin in our backend, and while planning the software architecture for a switch to a new ledger technology, it became evident that hardwiring a new cryptocurrency to our updated system would be a little short-sighted. Instead, we started abstracting all cryptocurrency ledger operations — like wallet creation, balance queries and payments — into a layer between our business logic and the underlying ledger. Using this layered approach, the switch from one default ledger to another will become relatively easy and we are not locked into a specific ledger or blockchain.

Multiple ledger support will also allow us to use different ledgers depending on the requirements of large corporate clients or industry verticals of our nanopayment settlement platform. This is where our long-term partnership with IOTA comes in. While we didn’t pick IOTA as the default ledger for our web content payment product, we will continue to evaluate IOTA for upcoming products, for example for white-label solutions or in the Internet of things sector.

What does this mean for SatoshiPay?

December (re)launch

To celebrate our launch we will organise events on 7 December in Berlin and 12 December in London. We will release more details about these events shortly! Follow us on Twitter to stay up-to-date.
