Achain is a simplistic and efficient blockchain platform in which users can execute smart contracts, digital assets and other decentralised applications. After two years in development, Achain has gained notoriety in the market with regards to the issuance of digital assets. Its exclusive, distributed consensus RDPOS (Result Delegated Proof of Stake) mechanism has integrated an intelligent Turing VM, with fully patented rights to intellectual property. The transaction speed of the chain is up to 1,000 transactions per second (TPS). Achain can create and carry out smart contracts, issue a number of digital asset types, handle evidence certificates, copyright protection and more. It is set to compete with NEO for the title of 'the next Ethereum'.Both are public blockchains, with the ability to execute smart contracts and applications. Both are driven by digital assets, with built-in cryptocurrencies and an open-source status. Of course, Ethereum uses a POW+POS consensus, while Achain works around its original RDPOS distributed consensus, which it is still working to improve. The primary point where RDPOS differs from DPOS is the element which undertakes the validation of an execution of a smart contract. DPOS deploys a correspondent node to execute a smart contract, so as to compare with the production block node execution. RDPOS, on the other hand, will dynamically determine whether smart contract verification should come via a correspondent node or all nodes. It does this by analysing the state of the result transaction when packaging the production block node. Achain and NEO perform a similar function, but if the Achain consensus method can be tweaked to perfection, then it could be the thing that gives it the edge over its rival when fighting for the title of 'next Ethereum'. It is certainly worth watching in the near future, if you are looking for the next big cryptocurrency to invest in.
