While the cryptocurrency world continues to swirl around in a daze of troughs and highs, startups are continuing to make use of the fundamental underlying strengths of blockchain technology.A new entrant in this race is Tradeshift, a leading players in supply-chain payments and marketplaces, which is today launching its new service which enables supports blockchain-based finance, or writing all transactions to a public ledger in order to create transparency and securing a record.While this doesn&t involve the use of currencies like actual Bitcoin or Ethereum, &having the transactions on a public ledger ensures full transparency and the ability for companies to prove that they have legit transactions,& says CEO and cofounder Christian Lanng.SO what this all means is that Tradeshift cloud platform will bring supply chain payments, supply chain finance, and blockchain-based early payments together into one unified end-to-end solution, called &Tradeshift Pay&.They are aiming at a $9 trillion problem, which is the capital trapped in &accounts receivable& as a result of old-fashioned payment practices and the disconnection between large business buyers and their suppliers.In other words, this could be a boon for small suppliers who find it hard to get paid when their invoices aren&t mapped to a ledger as strong as a blockchain.With this single unified wallet, buyers can use several payment options, including virtual card payments of invoices and purchase orders, dynamic discounting, supply chain finance through bank partners, or blockchain-based payments.
