MultiCurrency in Ethererum/RSK (1)

Filed under: Bitcoin, Blockchain, Ethereum, FinTech, Open Source Projects, RSK — ajlopez @ 9:26 am

In my post serie about connecting blockchains, I’m writing about exchange (value one to one, without change of value) between two popular heterogeneous blockchains (BitCoint and Ethereum/RKS). I’m a member of the development team of @RSKSmart, but those posts are personal opinions: the real work by the team was not published yet.

Another path to explore, is to have, in the SAME blockchain, many cryptocurrencies. My thought is that it could be done in Ethereum/RSK.

In Ethereum, there are accounts with state, and the account state includes the cryptocurrency balance for the account. There is a “default” currency, the Ether. But I think this model could be easily extended.

Each account has a currency, too. The “default” cryptocurrency should be the Ether, but some accounts could be created with ANOTHER cryptocurrency as default currencty. Then, they form a separated set of accounts. One account with currency X, can transfer and can borrow value from another account with THE SAME CURRENCY X. In this way, the new set of account could leverage all the infrastructure of Ethereum, to have a pool of accounts that manage a “coloured” currency value, separated from the default/main one.

In the next post, I want to write about:

– How to define a new currency
– How to create an account with a new currency
– How to transfer between accounts with the same currency
– How to transfer between accounts with different currencies

Stay tuned!

Connecting Blockchains (6)

Filed under: Bitcoin, Blockchain, Ethereum, FinTech, Open Source Projects, RSK — ajlopez @ 7:07 pm

Previous Post

BitCoin is the best known blockchain. Ethereum is the “new kid on the block”, and it has its similarities and its difference with BitCoin. At first, Ethereum has running nodes, transactions, blocks, and a blockchain build by consensus:

The consensus is based on proof of work for each block added to the blockchain, like in BitCoin. But the internal structure of transactions, the state of world by block, are quite different. For example, there are accounts WITH STATUS, instead of unspent outputs as in BitCoin.

But the main, key difference, is that each account could be an smart contract. Each node has a Ethereum Virtual Machine that can run compiled smart contracts. A method in a smart contract could be invoked in each transaction. This new capability opens lot of new use cases.

Having smart contracts in Ethererum/RSK, is one of the motivation to connect both blockchain: BitCoin is limited, running scripts, and the smart contract world is new brave world to be explored.
