FAQ

What is Syscoin?

Syscoin is the Bitcoin-Powered ecosystem securing rollups (L2s and L3s) with
unmatched data availability. Syscoin gives superpowers to Bitcoin by providing
it the ultimate functionality of a modular execution layer and everything that
it needs to scale.



What are modular blockchains such as Syscoin?

The new paradigm is focused on modular blockchains. Rather than trying to
achieve everything (scalability, decentralization, security) on a single layer
(monolithic) blockchain, modularity involves multiple layers, where each layer
is optimized to a specific purpose. Syscoin, the security-focused base layer,
provides guarantees of ultimate security and decentralization to all the super
fast low-cost layers that are built on top or that are integrated with Syscoin’s
zkDA.



How does Syscoin provide scalability?

Our unique data availability helps scaling layers offer their users fees reduced
over 1000% and the ability to provide practically limitless throughput with
successive layers. Soon, further advancements such as Syscoin’s zkDA will enable
other ecosystems to inherit the security of Syscoin’s data availability plus
interoperability with all other ecosystems utilizing it.



What are some rollups that use Syscoin?

Rollux is an OPStack (Optimism-based) L2 rollup that is EVM-equivalent and
utilizes Syscoin’s data availability. Rollux also provides native data
availability based on Syscoin, enabling L3s on top of it. Cartesi enables
application-specific rollups with a Linux runtime, transcending EVM limitations,
and utilizes validity (zk) proofs and Syscoin’s data availability.



How does Syscoin help Bitcoin?

In multiple ways! First, it’s important to understand that we view Bitcoin as
the world’s premier and most-proven secure means of decentralized self-sovereign
digital ownership and transfer. That same decentralized security provided by
Bitcoin’s Proof-of-Work network of miners is extensible through a process called
merged mining, which Satoshi himself created and introduced to Bitcoin Core in
2010. This means Bitcoin’s network is capable of supporting far more than just
storing and sending some BTC or an ordinal. In fact, technically it can already
support everything Ethereum can, and more, without any Core protocol changes.
However, for Bitcoin’s network to tap into this, an appropriately designed
merge-mined modular blockchain is required, and Bitcoin miners need to support
it. This is where Syscoin comes in.

Syscoin also helps Bitcoin by incentivizing Bitcoin’s miners with the utility
coin $SYS. While BTC rewards continue to diminish, the Bitcoin miners who
merge-mine Syscoin get the additional $SYS incentive at practically no extra
cost. That incentive is tied to limitless utility, and this helps them to
continue to support Bitcoin and keep its network decentralized indefinitely into
the future.



Do any large Bitcoin mining pools support Syscoin?

Yes. Three of the top five Bitcoin mining pools, and some smaller pools, already
contribute their total Bitcoin hashrate to the Syscoin ecosystem through merged
mining. At the present time Syscoin’s hashrate typically reflects 50 to 60% of
Bitcoin’s total hashrate. We are happy to assist additional pools with
merge-mining so they can provide $SYS to their miners at practically no extra
cost.



Does Syscoin depend upon Bitcoin in order to function?

No. Any SHA-256 miner can mine or merge-mine SYS. Mining SYS is not exclusive to
Bitcoin. Since 2016, Bitcoin miners continue to represent the vast majority of
hashrate mining SYS. Realistically this will continue. However, should they
cease for any reason, SYS is supported by other miners, so the network and chain
would continue.



Is Syscoin parasitic to Bitcoin?

No. To begin with, Syscoin's functionality does not depend upon Bitcoin's
network. Going further, SYS is a utility-focused coin with economics based on
EIP-1559, thus does not intrude upon BTC's scarcity-focused economics. Also, SYS
is an extra incentive to Bitcoin's miners, encouraging their continued support
of the Bitcoin network despite diminishing BTC block rewards. Syscoin also is an
extension of Bitcoin's network that provides it with more functionality. In sum,
Syscoin is not parasitic and is beneficial to Bitcoin.



Is merged mining secure? What about selfish mining?

At the very least, merge-mining brings the same challenges as standard
Proof-of-Work. However, there are important considerations here beyond just the
distribution of hashrate supporting the chain. Ultimately, whether a merge-mined
chain is secure depends upon that chain’s own protocol. Syscoin is the first
blockchain to make merged mining truly secure. This is accomplished by providing
an additive layer of decentralized finality on top of the work of Bitcoin’s
miners. This is accomplished by a vast network of independently operated
non-authoritative incentivized Sentry full nodes which participate in randomized
multi-quorums to provide chainlocks. This actually makes Syscoin far more
difficult to 51% attack or “selfishly mine” than Bitcoin itself while still
keeping Bitcoin’s own PoW at the bottom of the stack. Even if only a single pool
mined Syscoin, an attack would still require that pool to control a
supermajority of all Sentry nodes, a practically impossible achievement. This
finality, which the Bitcoin parent-chain lacks, makes possible the unique data
availability we provide to Bitcoin’s community, and so much more that Syscoin
provides.



What is $SYS used for and where can I get it?

Don’t blow your finite BTC on gas fees for execution! Syscoin's native coin,
$SYS, is used across the ecosystem for gas and transaction fees and to
incentivize Bitcoin’s miners who support Syscoin as well as the Sentry nodes
that further enhance Syscoin’s security. This coin is very similar to ETH in
supply characteristics and deflationary dynamics. Acquire $SYS by heading to the
Get SYS page!



Where can I learn more about Syscoin's design and/or the philosophy behind it?

Our Foundation President and Lead Core Developer maintains a Medium covering
much of this in-depth and with some technical detail. Also, numerous interviews
and Spaces have been held over the years with the various Syscoin teams, and can
be found by searching X or Youtube.

White papers and other technical papers are available here.
