Advanced Tokens Blockchain
DAG-style Blockchain for Loyalty, Store Credit, Gifts and a lot more. Zero fees. What will you build with it?

What is Lyra?

Lyra is a technologically advanced crypto token issuance blockchain and processing platform, which allows merchants, governments, and individuals to create custom tokens that can be accepted by others in a closed-loop environments, or at the point of sale together with cryptocurrencies and fiat methods of payment.
Merchant Tokens (Loyalty programs, Store Credit, Gift certificates, Discount coupons)
Corporate tokens (Internal-departmental accounting, corporate perks, channel currency)
Government Tokens (national or local)
Personal Tokens (Inter-family money, school perks and rewards, collectibles)

Why Lyra?

The appetite for experimentation with private coins or tokens among governments and corporations is growing very quickly. Lyra’s technology with emphasis on flexible fees, unlimited TPS, instant transactions, small footprint, and point-of-sale compatibility makes it a perfect platform for this growing trend.

Main Features

Lyra was designed and developed from scratch using the latest techniques in blockchain design to solve the speed, size, and throughput (TPS) limitations.
DAG-style chain collection / blocklist architecture Eliminates the need for large size blockchains. The blockchain is distributed among clients (hence the name “blocklist”).
Super Light Clients / WalletsThanks to blocklist architecture, the client doesn’t need to keep a copy of the entire blockchain – just their own blocks (in many cases only very last block), making it possible to have a wallet implementation that doesn’t require cloud or web wallets, permanent connectivity or massive local storage. As an example of wallet’s efficientcy, we have successfully implemented the complete stand-alone wallet on Raspberry Pi.
Fungible and Non-fungible Tokens The tokens can be both indistinguishable and unique (personalized). In fact, there are uses for both inside most applications, with transition from fungible to non-fungible at the time of redemption. Example: fungible reward tokens (as accumulated loyalty points) and non-fungible discount/gift tokens (as loyalty reward redemption mechanism).
Pre-programmed Smart Contracts No Programming Needed – creation of new token takes just a few moments. Each token type is pre-programmed for particular use case. User just enters simple configuration parameters.
Instant Transactions It always takes less than a few seconds to process a transaction with Lyra, making it compatible with point-of-sale environment where guaranteed speed of transaction is a requirement.
Built-in Instant Token Exchange Capability Atomic swap based token exchanges are built in, allowing for instant token exchanges, which is critical for various situations such as redemptions and and loyalty program partnerships.
Compatible with Point of Sale Lyra Tokens Blockchain leverages point of sale integration from GRAFT.Network payment platform project and facilitates paying with tokens at the point of sale via certified integration with payment terminals (Verifone, Ingenico, others).
Flexible Transaction Fee Structure Most blockchains have built-in hardcoded fee mechanism with a sender paying the fees. Lyra has a flexible mechanism when the fee can be paid by the sender, the recipient, or both sides, depending on the transaction type and other configuration parameters. This flexibility enables implementing various use cases that would be impossible with traditional fee structure.
Permissionless or Permissioned Lyra blocklist can run in various configurations – permissionless or permissioned, decentralized or centralized, public or proprietary – depending on the use case. Contact the team if you are interested in running a proprietary Lyra network.

Current State of Product and Technology

The initial blocklist implementation has been completed. It’s capable of issuing tokens, storing blocks at the clients, facilitating transactions, fungible and non-fungible tokens, and token “redemption”.

LYRA will be launched first as permissioned network with a gateway and privately controlled authorizer nodes in order to establish the network, and flush out the technology. A permissionless network with DPoS (delegated proof of stake) consensus will be launched after this initial “settle in” period.


Market for the Loyalty programs itself (just for the loyalty management software) is estimated at $6.8B / year with 23% annual growth rate.

As rule of thumb estimate it’s fair to say that at least 10% ($1 out of $10 spent) is accounted for by loyalty points, store credits, gift certificates, etc. This figure is likely to grow in the coming years.

Corporate, government, and personal tokens represent young but very quickly emerging markets which allow entities to issue their own “stable currencies” or tokens tied to the internal unit of measure.

Being able to issue their own tokens that are easily accepted at the point of sale or redeemed makes Lyra tokens blockchain uniquely positioned to be the platform for such tokens issuance and redemption. Having a built-in exchange for tokens cross-acceptance further sets Lyra blockchain apart from the competition.


We’re ramping up the first commercial implementation of the blockchain – a Shopify integration, where over 500,000 active Shopify merchants will be able to utilize Lyra for a portable and persistent, server-less loyalty, store credit, and gift certificate solution.

We have also been communicating to a good size sample of government organizations and corporations who confirmed their interest in being able to issue internal tokens that can be connected to a regular point of sale environment.

In order to jumpstart the adoption, we are making token issuance and basic (slower) transaction fees 0 on the permissioned network, which will allow anyone to issue and transact with tokens for free. We believe Lyra is the only token issuance blockchain at this time that is offering that, which should lead to a lot of innovative token uses.

How it works

Lyra Tokens can be accepted by merchants via integrated ecommerce platforms, in a person-to-person format using mobile applications, or at the point of sale via GRAFT.Network enabled payment terminals.

Create and issue custom merchant tokens

Give them out as cash back rewards, store credit, gift cards

Customers redeem those at the checkout or in the store


LYRA blockchain development is lead by Slava Gomzin and the rest of the GRAFT.Network Team

Slava is a recognized technologist, veteran of payments industry, author of “Hacking Point of Sale” and “Bitcoin for Nonmathematicians”. The team is well established and consists of professionals who have come with solid blockchain and industry experience, with a proven track record in building blockchain, open platforms, payment terminal and point-of-sale integrations, and various other components necessary for the project of this nature. LYRA is a continuation of work on GRAFT.Network – a decentralized 2nd layer PoS based, instant authorization blockchain on top of Monero / Cryptonode and are continuing to build it up for accepting various cryptocurrencies at the point of sale.

Roll-out Roadmap


Lyra will initially run as a permissioned network (for use with Shopify and other integrated platforms and partnerships). We’re doing this to establish the network and solidify the technology.

LYPE tokens (for Lyra Permissioned) will be used by the network for authorizer node staking and as “gas” for certain types of transactions and will be distributed through the upcoming token sale.

(Note: Lyra project’s commercial gateways, partners, and third party developers, will have to purchase these tokens from the market in order to run the gateway).

Becoming an Authorizer

Lyra Permissionless Network will run on Delegated Proof of Stake (DPoS) consensus with 42 authorizer nodes. Those who stake on Lyra permissioned network will become the first set of authorizer nodes on Lyra Permissionless.
