Trustless, high-performance, layered-architecture, blockchain-based DLT protocol

Symbol supports high customization at both the network and individual node levels. Network-wide settings, specified in network, must be the same for all nodes in a network. In contrast, node-specific settings can vary across all nodes in the same network, and are located in node.

ABOUT SYMBOL

Bulit for everybody with unlimited unique features

Symbol uses cryptography based on Elliptic Curve Cryptography (ECC). The choice of the underlying curve is important in order to guarantee security and speed. The specific curve being used is the Twisted Edwards curve: −x 2 + y 2 = 1 − 121665 121666 x 2 y

  • Aggregate Transaction

    An aggregate transaction shares the same unverifiable header as a basic transaction, and this data is processed in the same way. Additionally, an aggregate transaction has a footer of unverifiable data followed by embedded transactions and cosignatures.

  • Cosignature

    A cosignature is a pair composed of a public key and its corresponding signature. Zero or more cosignatures are appended at the end of an aggregate transaction. Cosignatures are used to cryptographically verify an aggregate transaction involving multiple parties.

  • Extended Layout

    The aggregate transaction layout described earlier was correct with one simplification. All embedded transactions are padded so that they end on 8-byte boundaries. This ensures that all embedded transactions and cosignatures begin on 8-byte boundaries as well. The padding bytes are never signed nor included in any hashes.

  • Disruptor

    One main goal of Symbol is to achieve high throughput. In order to help achieve this goal, the disruptor21 pattern is used to perform most data processing. A disruptor uses a ring buffer data structure to hold all elements in need of processing. New elements are inserted into the next free slot of the ring buffer. Fully processed elements are removed to make space for new elements

aMazing experience

Symbol is a next generation, open source decentralized blockchain platform from NEM that connects businesses to blockchain, helping them to reduce cost, complexity, and find new ways to create value. It has increased speed, usability, security and flexibility - making Symbol the smart, pragmatic choice for both enterprise and developers.

Symbol will help businesses see the possibility of our platform and what it can do for them - helping them to reduce cost, complexity, and find new ways to create value.

Other Key Innovations

Consensus

Symbol has developed a novel consensus mechanism called PoS+, based on Proof-of-Stake and modified with an element of weighting from network activity and contribution to the node network.

Harvesting

Symbol has inherited key features from the original NEM public network, which the core developers have improved upon.

Node Ownership

Node owners will benefit from a network wide service fee charged to harvesters, awarding the node owner 25% of any block rewards earned by the remote harvesters hosted on a given node

Multi-Layer Multi-Signature Accounts

The Symbol public network will allow up to 25 co-signers per account, and a maximum depth of 3.

How it works?

Network Architecture

TThe Symbol blockchain platform is built from a layered network of nodes. Peer nodes form the backbone of the network, the first layer of the layered node architecture. These nodes provide a powerful, stable, and secure platform where transactions are conducted and immutably logged on the blockchain ledger.

Aggregate Transactions

The utility the Symbol platform is further exemplified through a novel feature called aggregate transactions. Aggregate transactions allow for multiple transactions involving multiple transaction signers to be processed in an “all-or-nothing” batch of transactions wrapped in a single outer transaction.

This powerful addition to the technology stack allows for trustless, peer to peer, multi-party asset swaps or trades. Beyond these functions it’s possible to issue any transaction available on the platform such as multisignature transaction signature transactions, mosaic issuance, and namespace renewal, as part of an aggregate transaction. Only aggregate transactions cannot be nested in an aggregate transaction.

Token Configurability

NEM has traditionally been quite an asset centric platform, allowing the issuance of configurable assets, in NEM platform terms. Symbol again takes this concept and crams it with new innovative modifications and improvements such as Mosaic Restrictions.

There are numerous configurations for mosaics, but for the sake of brevity we will focus only on those that allow for the issuance of Security Tokens.

Symbol is Your Blockchain Platform

Symbol is a developer-friendly blockchain platform for businesses. It reduces cost, complexity, and time-to-market so businesses can be more competitive.

Symbol offers flexible and secure customizable solutions through simple, yet powerful, built-in features. Developers are able to easily integrate blockchain technology into their projects or create powerful dApps using Symbol’s REST API. This allows creating a variety of architectural solutions with lightweight code efficiently, in any programming language.

Symbol provides access to both public and private blockchains, individually or as a hybrid, providing options to best suit your company’s needs. The public blockchain is a decentralized, open, and self-sustaining ledger that can be used by anyone. The private blockchain, on the other hand, offers higher speed and privacy.
