SHOWPLUS CHAIN 2.0
MAIN-NET
Overview of the Main-net
ShowPlus Chain's next-generation blockchain network, called SHOW, delivers industry-leading performance and scalability through an innovative architecture based on DAG (Directed Acyclic Graph) and BFT-DAG consensus algorithm.
The BFT-DAG consensus algorithm combines Byzantine Fault Tolerance with DAG structure to achieve transaction processing speeds of over 200,000 TPS and block generation times of 0.5 seconds.

Compared to traditional consensus algorithms like PoW, PoS, and PoA, this provides the following innovative advantages :
-
Unlimited scalability through parallel transaction processing
-
Maintains high security and decentralization levels
-
Energy-efficient consensus mechanism
-
Immediate transaction finality
-
Cross-chain interoperability support
Furthermore, the network enhances scalability through sharding technology and provides cross-chain bridges with major blockchains such as Ethereum, Polygon, and Solana, enabling seamless integration with the global blockchain ecosystem.
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
Current Ethereum's limited transaction processing speed (15-30 TPS) leads to severe performance degradation and high gas fees during network congestion. This limitation becomes particularly apparent when executing complex smart contracts.
Shopple Chain fundamentally solves these issues through innovative DAG technology and sharding:
-
200,000+ transactions per second (6,600x improvement over Ethereum)
-
Minimized network load through DAG-based parallel processing
-
Instant transaction processing with 0.5-second block generation
-
Maximized execution efficiency with WASM-based smart contracts
-
Unlimited scalability through sharding technology

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
ShowPlus Chain processes high-performance computations directly on-chain by combining WASM-based smart contract execution environment with In-Memory computing technology. This enables efficient handling of complex operations such as DeFi calculations, NFT minting, and large-scale data processing.

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.
