EvrLight and Nostr4Evr
*EvrLight uses Evrmore as Layer-1 for diverse
Lightning assets like Bitcoin is Layer-1 for
Lightning money*
The EvrLight Announcement
The announcement of EvrLight, which was made on Oct 31st
2023 on the first anniversary of Evrmore's launch, is
recorded here. It provides a good summary of why EvrLight is
important and why it can be important to Nostr:
Those of you who have followed my work know that much of it
has focused on low-level protocol. In 2018 I began working
with the Medici developers to debug Ravencoin's basic UTXO
asset functionality, and eventually it led to the planned
enhancements documented in the Evrmore whitepaper. But most
importantly, I know that Evrmore must attract users and
developers for real-world use cases. Doing so requires
interfacing with other projects and communities. To
accomplish that, I have increasingly focused on asset atomic
swap technology as a key building block. I spent substantial
effort 2 years ago debugging asset HTLCs on testnet and
successfully executed cross-chain atomic swaps of assets in
exchange for Bitcoin. I implemented that asset functionality
with some needed bugfixes on Evrmore's mainnet when it
launched a year ago.
Earlier this year I went even deeper down the HTLC rabbit
hole to understand in detail how Komodo's AtomicDEX
technology functions and what it would take to support EVR
and Evrmore Assets. I turned on EVR support in AtomicDEX but
decided not to invest the time yet to implement Evrmore
assets in AtomicDEX because I realized something much more
important.
I realized that since
a) Bitcoin and Evrmore are both based on
UTXOs and addresses,
b) Bitcoin-Lightning is based on HTLCs
and secret-locked invoices, and
c) Evrmore supports HTLCs for both EVR
and Evrmore Assets in a very Bitcoin-like way,
that means something hugely important:
It means that
Evrmore is the perfect Layer-1 for diverse Lightning
assets in the same way that Bitcoin is the Layer-1 for
Lightning money.
In retrospect it is obvious, like the way many of the best
inventions are. This technology, which I call EvrLight, is
an enhanced protocol based on BTC-Lightning submarine swap
technology interacting with the Evrmore on-chain UTXO
Assets. It takes advantage of the strengths of both Evrmore
and Bitcoin-Lightning to enable users to buy and sell
Evrmore Assets using only a Lightning-capable Bitcoin
wallet, the EvrLight protocol, and associated automation
code. It will enable transactions which are atomic and
non-custodial, with low fees, and 1-conf average settlement
time of just over 2 minutes. Moreover, the transactions will
be privacy-enhanced because the Lightning invoice payment
leaves no on-chain record of the source of the Bitcoins. I
have been working through the details and have documented
the first draft of my work for other developers to study,
begin testing, and help generate reference code examples for
different languages. It will take time for developers to
implement it in applications before end users can enjoy its
benefits. But it is certainly worth celebrating with this
announcement on Evrmore's birthday.
EvrLight will make it possible to build asset-based Commerce
and DeFi applications for users who do not need to know
anything about Evrmore. But all commerce, including a DEX,
also requires an orderbook or other mechanism for buyers and
sellers to communicate. Therefore I also want to highlight
the strategic opportunity which is emerging from the Nostr
protocol. Like Evrmore, Nostr embraces the core values of
Bitcoin and a focus on protocols. From a technology
viewpoint, Nostr is a perfect fit for EvrLight. Not only are
many of the Nostr developers also Lightning developers, but
Nostr's users generate a private/public key pair as their
effective user ID, and that key can be directly translated
to an Evrmore address. That means that, without any prior
communication, you can directly interact with Nostr users
for EvrLight transactions using their address and know that
they will have the needed private key.
Nostr is still a tiny project compared to its competitors,
and one of the biggest challenges will be in finding a
revenue model which can support the needed infrastructure
and developers to compete with the well-financed social
media titans. EvrLight can provide the tools to add powerful
peer-to-peer social commerce and DeFi capabilities to Nostr.
I am working on an EvrLight example application for Nostr
and a list of apps worth writing, which I will promote under
the name Nostr4Evr. I hope other developers will join me.
Working with Nostr is a win-win opportunity.
As most of you know and anyone can see in the
explorer, we have
accomplished our work this year without touching the
minerdevfund. As the price of EVR rises, the Evrmore
Foundation will begin using your minerdevfund as intended to
pay a few part-time followed by full-time developer salaries
and bounties to help speed up the pace of progress.
There has never been a more exciting time for Evrmore. We
are just getting started. Welcome to the new world where the
EvrLight protocol will make it possible to buy and sell
Evrmore assets using only a Lightning-capable Bitcoin
wallet. See the
website
for more information.
Happy Birthday Evrmore !!!
