collecting, with a join block in the blockchain, transactions, the join block adjacent the blockchain block; encapsulating the shard creation transaction; applying the block including the shard creation transaction to yield a new shard in the block; and broadcasting the block. ## Claims ### Claim 1 A computer-implemented method, comprising: receiving from a decentralized app (dApp), a shard creation transaction in a blockchain block of a blockchain, the blockchain block comprising pre-existing shard(s), the shard creation transaction creating shard processing resources; collecting, with a join block in the blockchain, transactions, the join block as a special blockchain block at an interval, the join block executing cross shard transactions without impacting parallel execution of intra-shard transactions with separate processing resources by separating inter-shard and intra-shard transactions into different blocks; ceasing, by all nodes, processing any intra-shard transactions; encapsulating the shard creation transaction; applying the join block including the shard creation transaction to yield a new shard in the blockchain block; and broadcasting the blockchain block having the new shard. ### Claim 2 (depends on 1) The method of claim 1, further comprising receiving a transaction from the dApp for the new shard; executing, the transaction as input in processing resources assigned for the new shard; encapsulating the executed dApp transaction into the new shard in the blockchain block; verifying the executed dApp transaction; and applying the blockchain block after verification. ### Claim 3 (depends on 2) The method of claim 2, further comprising receiving a connect transaction from the dApp, the transaction comprising a destination and source; and connecting a destination and source shard. ### Claim 4 (depends on 1) The method of claim 1, wherein the multiple shards have their own permissions. ### Claim 5 (depends on 1) The method of claim 1, wherein only transactions created by the dApp for a specific shard are added to the specific shard. ### Claim 6 (depends on 5) The method of claim 5, further comprising executing the transactions for different shards in parallel by different processing resources. ### Claim 7 (depends on 6) The method of claim 6, further comprising configuring different processing resources to share a same memory space of node processing resources. ### Claim 8 (depends on 7) The method of claim 7, further comprising configuring the different processing resources to run in different hardware threads and CPU cores of a computer server. ### Claim 9 (depends on 8) The method of claim 8, further comprising joining together software threads to execute a join block transaction. ### Claim 10 (depends on 1) The method of claim 1, further comprising ceasing shard execution when a join block is executing. ### Claim 11 (depends on 1) The method of claim 1, further comprising communicating between sibling chains via the join block. ### Claim 12 (depends on 1) The method of claim 1, further comprising sharding a block on the same node via multithreading. ### Claim 13 (depends on 1) The method of claim 1, further comprising forking an existing chain and preserving a state of the existing chain in a new chain. ### Claim 14 A system, comprising: one or more processors of a machine; a non-transitory memory storing instruction that, when executed by the one or more processors, cause the machine to perform operations comprising: receiving from a distributed app (dApp), a shard creation transaction in a blockchain block of a blockchain, the blockchain block comprising pre-existing shard(s), the shard creation transaction creating shard processing resources; collecting, with a join block in the blockchain, transactions, the join block adjacent the blockchain block, the join block executing cross shard transactions without impacting parallel execution of intra-shard transactions with separate processing resources by separating inter-shard and intra-shard transactions into different blocks; ceasing, by all nodes, processing any intra-shard transactions; encapsulating the shard creation transaction; applying the join block including the shard creation transaction to yield a new shard in the blockchain block; and broadcasting the blockchain block having the new block. ### Claim 15 A non-transitory machine-readable medium embodying instructions that, when executed by a machine, cause the machine to perform operations comprising: receiving from a distributed app (dApp), a shard creation transaction in a blockchain block of a blockchain, the blockchain block comprising pre-existing shard(s), the shard creation transaction creating shard processing resources; collecting, with a join block in the blockchain, transactions, the join block adjacent the blockchain block, the join block executing cross shard transactions without impacting parallel execution of intra-shard transactions with separate processing resources by separating inter-shard and intra-shard transactions into different blocks; ceasing, by all nodes, processing any intra-shard transactions; encapsulating the shard creation transaction; applying the join block including the shard creation transaction to yield a new shard in the blockchain block; and broadcasting the blockchain block having the new block. ### Claim 16 (depends on 15) The medium of claim 15, wherein the operations further comprise receiving a transaction from the dApp for the new shard; executing the transaction as input; encapsulating the executed dApp transaction into the new shard in the blockchain block; verifying the executed dApp transaction; and applying the blockchain block after verification. ### Claim 17 (depends on 15) The medium of claim 15, wherein the operations further comprise receiving a connect transaction from the dApp, the transaction comprising a destination and source; and connecting a destination and source shard. ### Claim 18 (depends on 15) The medium of claim 15, wherein the multiple shards have their own permissions. ### Claim 19 (depends on 15) The medium of claim 15, wherein only transactions created by the dApp for a specific shard are added to the specific shard. ### Claim 20 (depends on 19) The medium of claim 19, wherein the operations further comprise executing the transactions for different shards in parallel by different processing resources. ### Claim 21 (depends on 20) The medium of claim 20, wherein the operations further comprise configuring the different processing resources to share a same memory space of a node processing resources. ### Claim 22 (depends on 21) The medium of claim 21, wherein the operations further comprise configuring the different processing resources to run in different hardware threads and CPU cores of a computer server. ### Claim 23 (depends on 22) The medium of claim 22, wherein the operations further comprise joining together software threads to execute a join block transaction. ### Claim 24 (depends on 15) The medium of claim 15, wherein the operations further comprise ceasing shard execution when a join block is executing. ### Claim 25 (depends on 15) The medium of claim 15, wherein the operations further comprise communicating between sibling chains via the join block. ### Claim 26 (depends on 15) The medium of claim 15, wherein the operations further comprise sharding a block on the same node via multithreading. ### Claim 27 (depends on 15) The medium of claim 15, wherein the operations further comprise forking an existing chain and preserving a state of the existing chain in a new chain.
