Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for managing and indexing content in a blockchain platform. Various aspects may include receiving, at the blockchain platform, content-addressable data. Aspects may also include indexing the content-addressable data. Aspects may also include generating and serving a recommendation including the content-addressable data for one or more users based on user preferences. Aspects may also include receiving an interaction from the one or more users based on the recommendation. Aspects may include updating a state of a blockchain on the blockchain platform based on the interaction.

Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for bridging native tokens. Various aspects may include initializing a first blockchain by allocating a plurality of native tokens. Aspects may also include transferring, using a bridge, one or more transactions from a second blockchain to the first blockchain using locked tokens on the second blockchain as collateral. Aspects may also include minting new native tokens at the first blockchain when a value of transactions sum to the plurality of native tokens and the plurality of native tokens are backed by the locked tokens. Aspects may also include reporting, to the second blockchain, the amount of tokens used for the transaction fees in the one or more transactions. Aspects may also include burning, at the second blockchain, tokens corresponding to the amount of tokens used for paying transaction fees.

Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for cross-chain communication in a blockchain platform. Various aspects may include accepting, at a first blockchain, a first transaction including a message and a message payload. Aspects may also include validating, at the first blockchain, the message by signing the message using signature keys of one or more validators in a first set of validators of the first blockchain. Aspects may also include generating an aggregate signature based on the signature keys of the one or more validators in a first set of validators. Aspects may also include submitting a second transaction on to a second blockchain, the second transaction including the message and the aggregate signature. Aspects may include validating, at the second blockchain, the second transaction based on a shared registry.

Abstract: A method for blockchain management includes receiving a first definition for a custom blockchain on a blockchain platform, the first definition including definitions for default data structures. The method further includes initializing a virtual machine and configuring the virtual machine using the first definition. The method further includes receiving a second definition for the custom blockchain, the second definition including definitions for user-defined data structures. The method further includes further configuring the virtual machine using the second definition and executing the custom blockchain on the virtual machine.
