This is an introductory slide deck to learn about the tools that Algorand has to build Blockchain Solutions. SDKs are reviewed as well as getting started with Blockchain development. Algorand is a Permisionless Blockchain that scales to billions of users which has... Enterprise Speed: More than 1000 transactions per second, 4.27 second latency Instant Finality: There are no soft forks. Every transaction committed to the chain is final Layer 1 Assets: Organizations can easily create their own assets, with double-spending protection guaranteed by the protocol Atomic Multi-Party Transactions: Transactions can be grouped together. Either all transactions in the group are executed, or none of them are executed Algorand Smart Contracts: Small programs written in an assembly-like language that can be used as a replacement for signatures within a transaction using Teal: Transaction Execution Approval Language

Public blockchains are decentralized and no one has control over the network and they are secure in that the data cannot be changed once validated on the blockchain. Permissioned networks place restrictions on who is allowed to participate in the network and in what transactions. 23
