First Polish blockchain contract for commercial real estate
Polish start-up ShareSpace (www.sharespace.pl) has created in August 2018 the first office rent transaction in Poland based on blockchain technology. ShareSpace is the marketplace that allows to find, compare and rent coworking or shared office spaces online, due to the analytical tools and standardization of all offers. The advantage of using blockchain in the lease process is not only transaction security. The whole operation is automated, so the office administrator saves time and money on long-term negotiations. In turn, the tenant is able to find the right space and make a rent contract within a dozen of minutes. “Most lease agreements on the real estate market are concluded in a traditional paper form. Until now, the parties have exchanged scans of signed documents, not seeing each other and with no possibility of checking the identity. However, we strongly believe in this electronic documentary form, secured by the blockchain technology, because it allows full verification of both sides of the transaction “, says Robert Chmielewski, ShareSpace co-founder.
