Does anyone knows if it is possible to store more transactions in a block?
So far I understood that for each transaction generated, 1 block is created.|
Hyperledger Fabric claims to achieve a throughput of 3,500 transactions per second, which is clearly not achievable if in BigchainDB we create a block for each transaction.
I am having issue in transferTransaction functionality in bgchaindb,getting response - {"error": true,"message": "HTTP Error: Requested page not reachable","data": null }
and in bigchaindb-errors.logs, error is as -
HTTP API error: 400 - POST:/api/v1/transactions - Invalid transaction (InvalidSignature): Transaction signature is invalid. (bigchaindb_webapi - pid: 12335).
Note - makeTransferTransaction and signTransaction functions are giving output fine but getting error in this function - connection.postTransactionCommit(txTransferSigned).
Also,get and create transaction are woking fine too.
Can anyone help me on this?
Hey guys. I am researching BCDB possible application
came to this post
https://www.reddit.com/r/Bitcoin/comments/4j7wjf/bigchaindb_a_prime_example_of_blockchain_bullshit/
this post is very old (2016) maybe a lot of changed after that
can someone guide me how this was addressed in the end?
But BigchainDB's architecture is fundamentally flawed. All BigchainDB nodes, by design, connect to a single RethinkDB cluster. (RethinkDB is a distributed NoSQL database, kinda like MongoDB but better.) If something bad happens to that RethinkDB cluster, the whole blockchains goes down.
Hello; my team and I are currently looking to transition from locally stored flat files with our wallet and chain to utilizing bigchainDB; everything has been going fine thus far and I'm not sure if we will run into issues. However I was looking to see if there is anyone around here with experience utilizing the software specifically that we can bounce questions off real-time when the conversion takes place.
The "Amount" in our system is a little unique than most in it isn't currency, however all other aspects follow a typical blockchain deployment.

ValueError: recipients list cannot be empty How to solve it??
Hello everyone.I am running single bigchaindb server node and also successfully making transactions but transactions are nor saving on bigchaindb and neither giving any errors.Unconfirmed transactions are zero.Is it because of single node?
