PLATFORM
SHOWPLUS CHAIN
MAIN-NET
The blockchain network of the Show+ Chain is designed in a private form and
uses a PoA (Proof-of-Authority) consensus algorithm.
PoA is a consensus algorithm that uses pre-approved
permissions to verify the validity of transactions.
The PoA consensus algorithm can reach a consensus faster than
the PoW (Proof-of-Work) and PoS (Proof-of-Stake) used in other Side Nets
and Main Nets, so it can reduce the transaction consensus time.
Coin information
Overcome the limitations of existing major coins
Disadvantages of existing major coins
Systems that use the proof-of-work (PoW) method,
such as Bitcoin and Ethereum, which are existing major
coin blockchain forms, support about 10 transactions per
second, and Tendemint, which uses the PBFT-based
Proof-of-Stake (PoS) method, is known to support about
1,000 TPS with 100-200 nodes.
Resolved by generating a transaction
Due to the low TPS shown by Ethereum, the TPS of Ethereum's
transactions is further reduced when the Ethereum network
becomes congested. Transactions that are deployed
on the network have put more load on the network as the
content of the transactions becomes more complicated.
If simple transactions can be generated,
the sharp drop in TPS can be reduced.
Limitations of blockchain computing
In addition, when the internal function is complicated,
such as the process of performing an operation, in the function
call of the smart contract, the overhead increases.
Due to the increase in overhead, the speed of the Ethereum
network is slowed down, and there is a possibility that the
use of the Ethereum network may become impossible.
Decentralized distributed method
Complicated calculations such as encryption are reflected by
entering encrypted data after proceeding outside
the blockchain, not inside the blockchain,
and the Show+ Chain network was developed based on
a private network that aims to implement a decentralized
distributed blockchain system with fast speed
and high performance at the single node level.
Advantages of PoA Private Network
Optimized blockchain
it can provide an optimized
blockchain service by developing
a smart contract that minimizes
gas costs based on the maximum
and estimated values of gas costs
for the data structure and number
of parameters when calling
functions of smart contracts.
Optimization of tests
it optimizes testing. Testing
environments to save gas costs
are carried out using Geth 1.8.15
and Mist 0.11.1. Although more
accurate results can be obtained
by conducting tests on Main Net,
tests are conducted on the
testnet "Showby" to consider the
fact that actual money must be
used to deploy. Rinkeby uses PoA
as a consensus algorithm.
Easy to measure costs
it can measure the gas cost
based on the structure and
number of data in internal
functions and parameters when
executing functions. By
measuring this, it provides a way
to determine the most efficient
way to store the same data by
which method in smart contract
configuration.
Smart Block
Show+ Chain has developed SmartBlock, a mechanism that intelligently
loads a local, privacy-preserving alternative to a blocked resource that
works well enough like the original resource to ensure the service is
functioning properly. With Tracking Protections, SmartBlock intelligently
corrects malfunctions or blank pages without violating user privacy.
SmartBlock also provides local bandwidth for blocked third-party tracking
scripts and performs modification. These standalone scripts operate
similarly to the original scripts that can verify that the website is working.
With these features, damaged sites that rely on existing scripts can be
loaded as they are. In the third version of SmartBlock, support for
replacing popular Google Analytic scripts has been significantly improved,
and support for popular services such as Optimizely, Criteo, Amazon TAM,
and various Google advertising scripts has been added.
These replacement features of SmartBlock are bundled into the
Pando Browser and no third-party content of the tracker is loaded,
so users cannot be tracked in any way.
Core Code
For the core setting, Show+ Chain has replaced the existing 32-bit
implementation of Curve25519 with an implementation of the Fiat-Crypto project.
The arbitrary precision arithmetic function of this implementation has been
functionally proven to be correct and is 10 times faster than the previous code.
Show+ Chain updated its 64-bit implementation to a new HACL* code, achieving
about a 27% speed improvement compared to the previous version.
Pando Browser recently provided this update to Windows as well. These
improvements are very important. Curve25519 forms the most widely used elliptic
curve form of ECDH(E) key setting in the Pando Browser, and the energy
consumption is reduced compared to the processing capacity increase when
applied to mobile devices, which is particularly important for mobile devices.
<32-bit Curve25519 with Fiat-Crypto>
<64-bit Curve25519 with HACL>
The arithmetic properties of Curve25519 are as follows:
𝑦^2= 𝑥^3+48662𝑥^2+𝑥
The curve used is the Montgomery curve above the prime field defined by the
prime 2^255−19. And the base point is 𝑥=9. This base point generates a cyclic
subgroup of the prime order. This subgroup represents the prime below.
2^252+27742317777372353535851937790883648493
The Co-factor of this subgroup is 8, which means that the number of components
of the subgroup is 1/8. The Montgomery curve is defined by the following
equation (field K):
𝑀_(𝐴,𝐵) : 𝐵_(𝑦^2 )= 𝑥^3+ 〖𝐴𝑥〗^2+ 𝑥^
For specific A, B ∈ K, and simultaneously, B(𝐴^2−4)≠0
Show+ Chain has improved the performance of ChaCha20-Poly1305 for
encryption and decryption. ChaCha20-Poly1305 is an
AEAD (Authenticated Encryption with Additional Data) algorithm that combines
ChaCha20 stream cipher and Poly1305 message authentication code.
The ChaCha20-Poly1305 algorithm generally provides better performance than
the AES-GCM algorithm, which is widely used in systems without hardware
acceleration on the CPU.
The vectorization using 128-bit and 256-bit integer arithmetic (using AVX2 instructions set
on x86-64 CPUs) doubled the processing capacity. If these functions are not available,
NSS is replaced by AVX or scalar implementation, both of which are further optimized.
Architecture
Distribution information
Show+ Chain will be allocated for the development and transactions of applications
that can be used in the Show+ Chain ecosystem, inducing participation in the ecosystem,
encouraging information utilization and transparency, and managing the transparent
records of the information. Additionally, it will be utilized for marketing, listing,
and developing an independent blockchain network, maintenance,
platform establishment, contingency plans for market fluctuations, etc. to expand
the Show+ Chain ecosystem through partnership and cooperation with other businesses.
