Join us for a great session on tap about everything new with the Algorand blockchain. We will take a look at these new features and provide demos using goal and the SDKs. The first half of the session will provide an overview of these features and the second half will focus on code samples. Algorand’s Rekeying feature allows users to change their private spending key without the need to change their public address. Fast Catchup enables developers to quickly sync a node and get started developing. Algorand Smart Contracts - Algorand now provides both stateless and stateful smart contracts that can be used to build on-chain applications that scale. Indexer V2 - Algorand’s new Indexer now provides the ability to do historic-based and paginated result set searches across the entire blockchain in an efficient and fast way. Review getting started code, using V2 SDKs, for transactions and building stateless and stateful applications. In this session you will learn... How to build blockchain solutions using the V2 SDKs. How to change the account private key without changing the public key. How to spin up a node and have it synced in a matter of minutes instead of days How to search the Algorand blockchain in an easy way.

How? • I create a node and can not use it for days. Catching up from the genesis block takes forever! • The cost and speed of other smart contracts make business models hard, UX spotty and tough to implement • How do I do searches on the Blockchain? Quick! 12
