An Introduction To Stellar And XLM: Mission, Control, And Consensus

This project is an enigma. On the one hand, Stellar is not for
profit, it doesn’t have owners or shareholders, and strives to be
somewhat decentralized. On the other, Stellar is a
compliance-focused protocol, and its directors often meet with
shadowy organizations like the World Economic Forum. According to
their website, the protocol seeks “to unlock the world’s economic
potential by making money more fluid, markets more open, and people
more empowered.” Fine, but, at what cost? Related Reading | Stellar
To Power VISA’s New Partnership, XLM Begins Breakout According to
the legend, Stellar is a Ripple fork. However, as you’ll see below,
that’s not exactly true. Founder of the infamous Mt. Gox
cryptocurrency exchange and co-founder of Ripple, Jed McCaleb,
launched Stellar in 2014. Joyce Kim, a lawyer, was his partner in
the venture. Stripe financed the initial operation. The native
currency of the whole Stelar ecosystem is called Lumen or XLM.
Stellar’s Mission And Approach The recently appointed CEO and
Executive Director of the Stellar Development Foundation, Denelle
Dixon, was recently interviewed by Securities.io. “The vision is
big: Stellar and SDF hope to unlock the world’s economic potential
by making money more fluid, markets more open, and people more
empowered,” she told them. On its website, Stellar justifies its
existence by telling us. “The way the global financial
establishment is structured today, people are born into an economy
just like they’re born into a political system. Stellar is a way
out: it lets people participate in a worldwide, stable, financial
network regardless of where they live.” The controversial aspect is
Stellar’s approach. It’s completely opposed to the cryptocurrency
ethos. The company wants to build a bridge between the traditional
banking system and the cryptocurrency space, but by following the
traditional banking system’s rusty rules. “The software has always
been intended to enhance rather than undermine or replace the
existing financial system.” In other words, Stellar aims to
provide a platform with which all financial actors can interact
without any friction. All financial actors that are properly
identified and approved by the legacy system, that is. What
Is The Stellar Consensus Protocol? As a consensus mechanism,
Stellar doesn’t use Proof-Of-Work or Proof-Of-Stake. It uses its
own Stellar Consensus Protocol (SCP.) For a formal definition,
let’s quote the paper that Stellar presented at the Symposium on
Operating Systems Principles. How did Stellar solve the Byzantine
general problem? “With SCP, each institution specifies other
institutions with which to remain in agreement; through the global
interconnectedness of the financial system, the whole network then
agrees on atomic transactions spanning arbitrary institutions, with
no solvency or exchange-rate risk from intermediary asset issuers
or market makers.” And, what does the Stellar Consensus Protocol
accomplish exactly? “SCP lets Stellar atomically commit
irreversible transactions across arbitrary participants who don’t
know about or trust each other. That in turn guarantees new
entrants access to the same markets as established players, makes
it secure to get the best available exchange rates even from
untrusted market makers, and dramatically reduces payment latency.”
For the system to function, Stellar relies on Federated Byzantine
Agreements. For a description of what those do, let’s quote
Bit2meAcademy: “For the FBAs to function properly, participants
must wait for the majority to reach a consensus. In this way,
participants know which transactions are most relevant before
starting to settle them. So when the majority of the network takes
a position, the network accepts the transaction and makes it
unfeasible to roll it back for an attacker. In other words, the
Stellar Consensus Protocol tends towards centralization and just
ignores most of the problems that Proof-Of-Work solves. It does use
significantly less energy, though. XLM price chart for 09/04/2021

Characteristics Of The Stellar Blockchain Almost all of the Stellar
validators are corporate entities of some sort. Or are maintained
by the Stellar Development Foundation. However, “anyone can
install the Stellar software and join the consensus process.” Each
Stellar Lumen account must have a minimum of XLM in them. This
minimum balance protects the network from spam accounts. The
Stellar Lumen’s mission is to pay for gas to conduct operations
inside the Stellar ecosystem. The Stellar ecosystem was not
designed for direct payments. The idea is to provide a platform to
serve as an intermediary in currency exchange. The system “doesn’t
privilege any particular currency.” The code is open source and
auditable by anyone. “The Foundation helps maintain Stellar’s
codebase, supports the technical and business communities around
Stellar,” great! “And is a speaking partner to regulators and
institutions,” ow. Stellar recently signed a partnership with
“crypto-asset risk management solutions” firm Elliptic. That means,
“Elliptic’s monitoring, compliance, and analysis software now
incorporates support for XLM, the native asset of Stellar.” Ow.
With the recent protocol 13 update, Stellar allows “fine-grained
control of asset authorization.” This means the issuer of an asset
can deauthorize accounts and don’t let them use the asset. This
means, more control and permissions. The Lumens had an inflation
rate of 1% per year. In September 2019, Stellar removed inflation
of Lumens. Also, the Stellar Development Foundation burned 55B of
their Lumens. So, Is Stellar a Ripple Fork? In its FAQ,
Stellar goes back to its origins: “The old Stellar network launched
in July 2014. The node software (stellard) was a modified fork of
the Ripple node software (rippled). The ledger was completely new
and contained no history from Ripple’s network.” Related Reading |
Stellar To Introduce AMM Functionality, What This Means For Its
Ecosystem So, the software was originally based on Ripple’s, but
the ledger was brand new. Nevertheless, in 2015, when they released
the Stellar Consensus Protocol, they re-wrote the software from
scratch. From that point onwards, Stellar doesn’t share any code
with Ripple. Featured Image by Nicole Avagliano on Unsplash -
