Procurement is a primary function that organizations use to interact with their external business partners. The technology used to manage both buyer and supplier networks has become more complex. The procurement teams are good at negotiating deals but struggle with executing them. Legal, procurement, supply-chain, and finance all operate in a loosely coupled, internally optimized environment within the enterprise. Traditional ERP systems struggle to handle volume discounts and business rules in procurement across multiple subsidiaries, divisions, and partners. The complexity of today’s contract execution requirements causes a significant amount of contract leakage, which results in a gap between the negotiated and realized savings.

Hedera is owned by some of the most respected organizations in the world. Hedera is the most widely used enterprise-grade network that allows you to create your digital world. HBAR, the native, energy-efficient cryptocurrency from Hedera that powers decentralized economies, is called Hedera's HBAR. Hedera is open to all, regardless of whether you are a startup, an enterprise, or a consumer. It goes beyond the blockchain for developers to create the next generation of fast, fair and secure applications. Bitcoin was the first to use decentralized infrastructure, and Ethereum introduced programmability. However, proof-of-work blockchains of the past consume huge amounts of energy and take a long time to process transactions in order achieve acceptable levels security. These technologies consume a lot of bandwidth and can charge high fees even for a simple transaction. The Hedera proof of-stake public network powered by hashgraph consensus achieves the highest level of security (ABFT).

A new blockchain and smart transaction platform that is more efficient, secure, and easier to use. We believe cryptocurrency should be more accessible than cash, easier to lose, and almost impossible to steal. Anyone who needs to validate transactions should have the ability to farm without a lot of hardware or electricity. Bram Cohen, the creator of BitTorrent, has created Chia Network, a blockchain and smart transaction platform. It implements the first ever new Nakamoto consensus algorithm, since Bitcoin in 2008. It implements the first new Nakamoto consensus algorithm since Bitcoin in 2008. It will make cryptocurrency more accessible than cash. Refer to the following smart transactions: Colored coins and rate-limited wallets.

zkSync is Ethereum’s most user-centric ZK rollup. ZK rollup does not have an upper limit on the amount it can safely handle in L2. This is unlike any other scaling strategy. All assets can be moved capital-efficiently between ZK rollups and L1. This is in contrast to optimistic rollups. zkSync has the lowest real transaction costs of all planned and existing rollups. zkSync supports meta-transactions and instant confirmations with economic finality. It also offers low-cost privacy and low-cost privacy. zkSync's design is easy and fun. In just a few lines of code, you can integrate payments and atomic swaps.

Bitcoin Lightning Network. Instant Payments. Lightning-fast, blockchain payments without the need for block confirmation. Blockchain smart-contracts ensure security without the need to create an on-blockchain transaction for individual transactions. Payment speed is measured in milliseconds to seconds. Scalability. The network can handle millions to billions in transactions per second. Legacy payment rails are thrown out the window by this capacity. It is now possible to attach payment per click/action without custodians. Low cost. Lightning Network allows for extremely low fees by transacting and settling off blockchain. This allows for emerging use cases like instant micropayments. Cross Blockchains. Cross-chain atomic Swaps can be made off-chain immediately using heterogeneous blockchain consensus rules. Transactios can be made across blockchains as long as they support the same cryptographic haveh function.
